5. Description of Individual Units - all Models

5.1. Setting of Cutting Angle

The machine design enables cutting the material in angle without material handling. The material is stable between the fixed and moving gripping jaws. The cutting angle is set by turning the band saw head including the rotary table Y after releasing the arresting lever Z of the table. The band saw head must be elevated while it is being turned so that the saw blade is above the bearing surface of the vice. When the required angle has been set (acc. to angle scale), secure the rotary table with the arresting lever Z of the table. The fixed stop serves for constant setting of the limit angles. No angle cutting is possible with the ARG 220 NC Automat model.

5.2.1. Setting of Vice Clamping Force

The hydraulic unit is provided with a PRESSURE CONTROLLER which enables the setting of the required vice clamping force between 15-35 bar depending on the workpiece type. Low pressure is used in cutting thin-walled sections so that their distortion in clamping may be avoided. Turning the PRESSURE CONTROLLER to the left decreases the pressure; turning to the right increases the pressure (see figure). The set pressure is displayed on the vice pressure display. If the pressure is set below 15 bar, the SAFETY PRESSURE CONTROLLER does not switch on and the saw blade does not start.

Prevent the hydraulic cylinder piston shifting out too far by correct adjustment of the gripping jaws. Wrong clamping can cause damage to cylinder sealing, prolongation of feed intervals and impact the accuracy of feed.

In order that the feed system may work accurately, there must not be any guide clearance on the moving vice gripping jaws. Therefore, the vices must be regularly checked and adjusted.

5.2.3. Moving Vice Feed System

The standard equipment of all moving vice models is a retarding system in end positions, both when the material is moved forward and backward.

Description of Cycle:

The moving vice clamps the workpiece, starting slowly to move forward (approx. 4 mm); then the induction sensor switches the hydraulic system over to the fast feed and the last 4 mm before the end position is achieved, it again switches over to the slow retarding speed. The same process repeats when the vice reverses. This system ensures maximum accuracy of workpiece feed, prevents workpiece skidding, delayed actions in end positions and mechanical impacts in the entire system. The retarding system also eliminates the weight loss of the work piece while it is gradually being cut off.

5.2.4. Setting of Feeding Speed of Moving Vice

The standard equipment of the hydraulic cylinder of the moving vice feed system in all NC Automat models is a control valve, which enables continuous setting of the feeding speed of the moving vice. The correct speed setting affects the speed of the cutting cycle including the accuracy of the feed. Lower speed of feed is used for heavy, full materials, for which the maximum accuracy is required. On the contrary, faster feed can be used for sections, which are usually longer.

5.2.5. Setting of Auxiliary Roller

The auxiliary roller moves on guide rods and serves for supporting short (end) workpieces, which do not reach the firm roller track. The auxiliary roller should be adjusted outside the zone of movement of the feed vice according to its feed length.

5.2.6. HVP 250, 300 NC Pressure Device for Bundle Cutting (special outfit)

The vertical hydraulic pressure device serves for clamping the material for cutting in bundles (except for ARG 220 NC Automat). The correct and sufficient clamping of all material pieces in the bundle substantially influences the saw blade life. The pressure device is adjusted to the clamping cycle of the fixed and moving vice.

The pressure plate serves for vertical clamping of the material. The pressure plate diameter is 70 mm (see figure). If a larger bearing surface is required, install your own fixture with required dimensions on the pressure plate.

5.3. Saw Blade Guide

The Saw blade is guided in two guide heads provided with eccentrically arranged bearings, which enable the saw blade winding more easily towards the guide on the moving wheels and the carbide guides on either side and the upper edge of the saw blade. The right guide head is mounted on the fixed guide bar. The left guide head is on the moving guide bar, moving in the distance of 5 to 10 mm from the workpiece. The guide bars are provided with saw blade protective enclosures as far as the cutting zone. There is no

saw blade protective enclosure in the cutting zone.

A timely replacement of the saw blade is necessary for achieving a good cutting power, the surface quality and the workpiece dimensions. High consumption of electrical power, scarf cuts and rough cutting surfaces are caused by blunt saw blades. One of the important factors affecting the quality of the cut and the life of the cutting tool is the correct and sufficient saw blade tension. The correct saw blade guide on the moving wheels and the guide heads affects substantially the saw blade life.

5.3.1. Saw Blade Replacement, Tension and Setting

The TOTAL STOP button is unlocked. Release the arresting lever of the end stroke of the band saw head so that band saw head stroke cam for elevating the band saw head in the upper position is released

elevate the band saw head in the upper position (see chapter 6).When replacing a broken S

(see fig. 5.5.). Switch on the MASTER SWITCH, depress

the hydraulic unit - START button. Shut off the control valve (see chapter 5.4). Switch over the machine to MANUAL MODE a

aw blade (the saw blade limit switch is not switched on), elevate the band saw head in the upper position by pressing the button 3 on the control unit (see chapter 6 - Manual mode). Switch off the master switch or isolate the machine from supply and secure it against restarting. Remove the rear guard of the band saw head. Releasing the tension grip, release the idler and thus the whole saw blade. Remove the saw blade from the moving wheels and push it off the guide heads (see chapter 5.3.2.). Insert the new saw blade in the guide heads. Put it on the moving wheels and tighten with the tension grip.

Tighten the tension grip so that the Belleville washers are pressed completely (no light appears) and the saw blade limit switch switches! In this way, the correct saw blade tension is achieved!

Note: These operations may only be carried out when the master switch is off and secured against restarting or when the machine is isolated from the network. Warning: Danger of injury by the sharp saw blade teeth. Use protective gloves. Do not touch the guiding wheels and the saw blade.

Close the guard, switch on the master switch or connect the machine to the network. Switch on the hydraulic unit and set the minimum saw blade speed. Start the saw blade by depressing the push-button Saw Blade Start so that it turns approximately once through. Make sure that the saw blade fits correctly in the guide heads. Restart the saw blade with the Start push-button and let it turn approximately once through. Switch off the master switch or isolate the machine from supply and secure it against restarting. Remove the rear guard of the band saw head to make sure that the saw blade is correctly fitted in the guide heads and correctly installed on the moving wheels (see figure). If the saw blade is not correctly installed on the moving wheels, release the tension grip and adjust the wheel setting with the screw (see figure). Tighten the tension grip so that the Belleville washers are pressed completely (no light appears) and the saw blade limit switch switches! Close the rear guard of the band saw head and switch on the hydraulic unit. Make a test run of the saw blade. Switch off the master switch or isolate the machine from supply, and check the fitting of the saw blade on the moving wheels. Repeat the whole procedure, if required. For casual checking of blade position can be used SAW BLADE GUIDE INSPECTION HOLE. Close the rear guard of the band saw head, switch on the master switch and the hydraulic unit. Adjust the stoke height of the band saw head (see chapter 5.5.). Carry out the first cut.

5.3.2. Guide Head Setting

The correct setting of the bearings and the carbide saw blade guides in the guide heads substantially\ influences the saw blade life and the quality of the cut. The eccentrically arranged guide head bearings must be set in such a manner that the saw blade surface is parallel to the carbide plate surfaces and the clearance between these plates and the saw blade is minimal.

FIXED

CARBIDE GUIDE

Guide Head Setting

Elevate the saw blade approx. 20 mm above the fixed gripping jaw of the vice. Switch off the master switch, isolate the machine from supply and secure it against restarting. Adjust the moving guide head so that the guide heads are approx. 20 cm from each other. Disconnect the supply hoses of the coolant valves. Unscrew the guide heads gradually from the fixed and moving guide bars, turn them through 180° (bearing and carbide guide upward) and screw to the bars again. Observe the perpendicularity of the guide heads to the bars and the identical height of the guide heads. Check the tightening of the fixed carbide guides. Insert approx. 30 cm of an old saw blade in the guide heads between the carbide guide and the bearings. Set the pressure carbide guides with the width setting screw of the carbide guides so that the saw blade moves without clearance between the carbide guides, but does not seize. When the saw blade is correctly set, adjust the eccentrically arranged bearings to prevent the bearings from "cutting" the saw blade but there must not be big clearance between the bearings. When the saw blade moves, the bearings are carried along by the saw blade. Check all the bolt connections for tightening. Unscrew the guide heads from the bars. Fit the saw blade on the moving wheels, checks its correct alignment on the moving wheels and tension the saw blade. Install both guide heads on the saw blade in the space between the bars and adjust their correct position on the bars. Than we move guiding heads up, so that the space between fixed carbide guides and upper part of saw band was approx 0,5-1mm. In this way, the correct guide head height towards the bars is set. Adjust the guide heads perpendicularly to the bars and tighten them. Close the rear head protective enclosure, switch on the master switch or connect the machine to the network. Switch on the hydraulic unit and carry out a short test run of the saw blade. Switch off the master switch, isolate the machine from supply, open the rear head protective enclosure and check the saw blade fitting on the moving wheels and guiding heads. Make corrections, if required (see 5.3.1.). Close the rear head protective enclosure, connect the machine to supply, switch on the master switch and hydraulic unit. Carry out the first cut.

5.4. Saw Blade Feed into Cutting Position

The control valve is situated on the central control board. It enables a continuous setting of the speed of the saw blade feed into the cutting position or its stabilization in any position by turning the valve mechanically. The examples of descent speed are shown in chapter 11.6. The optimum value can also be determined very easily by listening. The saw blade movement must be noiseless, free from vibrations. This condition can be achieved if the pressure force is increased or decreased (head decent speed). The condition for setting the optimum pressure is the selection of the correct cutting speed of the saw blade and the optimum size of the saw blade teeth.

the band saw head stroke cam, set the required stroke on the scale (approx. 15-20 mm above the workpiece section) and tighten the arresting lever.

The band saw head is elevated above the lower end position.

Switch the band saw to MANUEL MODE and lower the band saw head in the lower end position (see chapter 6.). Release the arresting lever of the head stroke cam, setting the required stroke on the scale (approx. 15-20 mm above the workpiece section) and tighten the arresting lever.

5.5. Setting of Band Saw Head Stroke Height

The system enables the setting of the head stroke height close above the workpiece. It is particularly important when material is cut in series. It substantially reduces the cutting cycle time in comparison with the situation if the head returned to the maximum upper position.

VICE PRESSURE VALVE

If you release the arresting lever and thus the band saw head stroke cam, the band saw head can be elevated to the maximum position. This procedure is used when the saw blade is being replaced - it enables easier access to the saw blade. The setting on the scale serves for guidance only. The stroke and the setting have to be tested, as required.

5.7. Cooling System

The pump and the coolant tank mounted in the base are the basic elements of the cooling system. The coolant tank can be dismantled separately from the pump. The coolant pump carries the coolant via hoses, cocks and guide heads to the saw blade. In addition to the main cooling via the guide heads, there is an auxiliary cooling. We recommend to install it after the fixed guide head. The coolant quantity is regulated by cocks on the guide heads. The coolant cools and lubricates the saw blade and flushes the metal chips. The pump switches on and off simultaneously when the saw blade drive is started or shut down. Installed in the coolant tank is a settling tank, which has to be cleaned during routine checks depending on the material cut.

When coolants are handled, the exposure to dangerous substances cannot be excluded. Observe in your own interest the instructions and recommendations of the producer or your company referring to safe coolant handling.

The overflow opening bored in the coolant tank provides for the supply of the correct quantity of coolant in order that the pump overflow is prevented (the pump could burn). If too much coolant is poured in, the coolant will flow out

below the band saw.

Caution - danger of injury! Carry out maintenance only when the master switch is off or the machine isolated from supply.

FU 2 or FU 3 fuse s burn out repeatedly.

The rectifier diode of one of the magnets is probably broken. Disconnect the terminal wires 76,79,82,86,88,89 and 90 on the X 1 terminal board, replace the burn-out fuse and switch on the machine. If the fuse burns out again, the short circuit is caused elsewhere. Check the switchboard or the limit switch for a shortcircuited earth conductor. Gradually connect the conductors disconnected from the terminals using the following procedure: connect one conductor and switch on the hydraulic system. If the fuse does not burn out, connect the next conductor, as soon as the conductor connected burns out the fuse, replace the respective magnet on the hydraulic unit.

The moving vice cannot be moved in manual mode

The switch must be in the Manual Mode position. The band saw head must be in the upper position on the BP3 limit switch. The stop must not be in zero position; it is necessary to set the required measure on a hand-operated counter or remove the stop by PLC. Both vices must be unclamped.

The H1 green signal light does not light up when the master switch is switched on

Check the Total Stop SB 1, the BP 2 limit switch of the band saw head and the BP 1 saw blade tensioning. Check the input voltage on the X1 supply terminal board with L1, L2, L3, N, Pe terminals, and/or the TR 1 transformer output voltage on 0 V and 24 V terminals.

The machine does not measure the length correctly

Make sure that no wire in the 96,97,67,95 terminals of the X1 terminal board has become loose. Make sure that the coupling between the IRC 1 sensor and the measuring screw is tight. If everything is all right, replace the IRC 1 sensor.

The stop does not stop at the required measure and the frequency converter signals an error at the end of screw

Switch off and on the hydraulic system of the machine. The error code is displayed on the frequency converter. Press the STOP RESET button on the frequency converter; after a while 0.0 will be displayed. Switch over the switch to automatic mode; the stop must start moving towards the zero position. After that, proceed in conformity with item "The machine does not measure the length correctly".

Check the protective enclosures of the machine for any damages and failures before starting everyday work.

Feed Line Checking

Make a regular check of the following items at least once a week: power line integrity • intactness of line connections and pull relief. Inspections and checks of electric appliances are subject to valid legal regulations of the respective country.

Machine Cleaning

Clean the machine thoroughly at regular intervals (always after the shift or during the shift, if required). Use appropriate cleaning agents. Do not use solvents (e.g. nitrosolvents). do not use compressed air for cleaning the machine! Otherwise the fine chips and impurities will penetrate under the sliding elements. Keep all induction sensors clean! (see figure).

Removal / Disposal of Metal Chips

Caution - danger of injury! Carry out maintenance only when the master switch is off or the machine isolated from supply.

The coolant tank can be removed from the machine base for cleaning and maintenance. The pump is restricted by the length of the connecting cable). Warning: The used up coolant is special waste!

Our recommendation: Regular cleaning and maintenance of the cooling system extend the life and the functionality of the coolant pump. Coolants miscible with water, non irritating the skin, highly ageing and corrosion resistant should be used. Oil content in the coolant should be checked at least once a week. Good lubrication increases the productivity of cutting. Integrated in the coolant tank is a setting tank, which should be checked in the course of routine checks depending on the material cut.

Hydraulic Unit

The hydraulic unit is maintenance-free. The

Lubrication

Regular lubrication and cleaning extend the life and the reliability of performance of the machine. While making routine checks, make sure there is sufficient grease on the vice friction surfaces and the trapezoidal screw and on the friction surfaces of the saw blade moving bar. Make sure that the measuring bar, the guide bars of the moving vice as well as the vice are thoroughly lubricated (see figure). Add grease, if necessary.

Pilous band saws are filled with PARAMOL HM 46 oil. The exchange of the oil charge is recommended within 5000 operating hours. The oil level in the oil level gauge on the hydraulic unit in the machine base should be consequently checked.

11. Saw Blades

The prerequisite of the correct cutting power of the machine is the use of high-quality saw blades. In order to achieve a high cutting power, it is recommended to use bimetallic saw blades. The main saw blade component is the high-quality heat treated steel with a high elasticity limit. The tooth edges are high-speed steel of the following quality: M 42, M 51.

M 42 - a saw blade for universal use for cutting metallic and non-ferrous materials within the whole range of quality classes up to the 45 HRC hardness. The saw blade is suitable for cutting full materials of all cross-sections and diameters, profiles, pipes and bundles.

M 51 - with reference to the M 42 saw blade, the M51 is designed first of all for cutting steel up to 50 HRC, steel of higher strength classes, acid-resistant and stainless steels, nickel, titan alloys and special bronze.

Carbide - high cutting power as compared to bimetallic saw blades. Suitable for cutting of steel, non-ferrous metals, material with high content of chrome, nickel, titan, stainless steel and face-hardened materials up to 62 HRC. The saw blades can be used for all materials including stainless steel, tool steel, non-ferrous metals, cast iron, plastics and fibreboards. These saw blades are characterized by a high thermal conductivity, high wear and tear and thus longer life, higher cutting speed, less frequent saw blade replacements and better productivity as compared with carbon steel saw blades.

Design: M 42 - composition: W 2%, Mo 10%, V 1%, CO 8%, tooth hardness: 68 HRC. For cuttingof materials up to 45 HRC Design: M 51 - composition: W 10%, Mo 4%, V 3%, Co 10%, tooth hardness: 69 HRC. For cuttingof materials up to 50 HRC Design: Carbide - tooth hardness 1600 HV. For cutting of materials up to 62 HRC

In addition to standard shapes and sizes of teeth, the saw blades are also manufactured with special features, such as saw setting, tooth angle and tooth face shape, which are used particularly for cutting of specific materials. Please contact your saw blade supplier to get more information about these features.

Saw Blade Tooth Arrangement

a) Constant - tooth edge spacing always equal. b) Variable - the tooth edge space is different, repeating periodically. This up-to-date saw blade design enables a bigger cutting range in one saw blade type. It is able to eliminate vibrations caused by the tooth edge touching the material and thus to achieve a clean smooth cut and longer life.

11.2. Tooth Size

The selection of the tooth size is of crucial importance for the saw blade life.

11.3. Optimum Workpiece Clamping

The correct workpiece clamping can substantially influence the saw blade life, the quality and precision of the cut and enables the correct selection of the tooth size. For bundle cutting, the use of the upper (vertical) pressure device is recommended. Observe the following kinds of clamping to achieve an optimum cut (life and cutting power):

Rule: At least four, but not more than thirty teeth must bite while a workpiece is being cut.

Note: The a.-m. values do not refer to cutting of different sections. Such a requirement must be treated with respect to the section shape, the number of pieces in the bundle and the dimensions. When the saw blade is used for cutting sections, its life becomes shorter by up to one third.

11.6. Values Recommended for Cutting

The selection of values depends on the material class and the material section. The table data serve only as a guide; they have to be adjusted to the material for certain ranges. The numbers of the CSN-Standards serve for information only. They define only the guide for the material properties for which the respective saw blade type is designed.

11.5. Factors Influencing Saw Blade Life

inappropriate saw blade tooth size • inappropriate saw blade speed and saw blade lowering speed in the cutting position • the saw blade (the whole band saw head) bears against the workpiece when the band saw is not in the cutting position • the workpiece is not clamped as recommended • the saw blade tension is not correct (mostly too little tension) • the saw blade is not correctly fitted on the guide wheels (the saw blade touches the wheel shoulder) • the saw blade guide heads are not correctly adjusted • the distance between the saw blade guide heads and the workpiece is too big • the oil content of the coolant is too low • the saw blade is not correctly run in • saw blade maintenance is bad, the metal chips have not been removed from the band saw.

11.4. Running-in New Saw Blades

The running-in refers to new saw blades. The sharp cutting edges with extremely small edge radii enable high cutting power. In order that the maximum tool life may be achieved, it is necessary to run in the saw blade to the optimum. Depending on the correct cutting speed and the workpiece feed and the quality of its material, the saw blade must be run in only with 50% of currently used feed. In this way the breaking of extremely sharp edges particularly in big workpiece sections will be prevented. These micro-fragments cause destruction of further teeth. Should vibrations or sounds due to oscillations manifest themselves when a new saw blade has been fitted, reduce the cutting speed slightly. In small workpiece sections it is recommended to run in the saw blade with a reduced power for 15 minutes, in big sections for 30 minutes. Then increase the feed slowly to the optimum value.

The a.-m. faults cause inaccurate cut, reducing the saw blade life and/or causing even its damage.
