Uncrating and assembly

6.0 Electrical connections

1. Finish uncrating the band saw. Contact your distributor if any damage has occurred during shipping.

2. Remove any preservative with kerosene or diesel oil. Do not use gasoline, paint thinner, or any cellulose-based product, as these will damage painted surfaces.

3. Remove two socket head cap screws from left side of vertical column. Attach shear assembly (A, Figure 1) to column by inserting hex cap screws.

4. Place rip fence onto table and tighten with locking knob.

Figure 1

All electrical connections must

be done by a qualified electrician. All adjustments or repairs must be done with machine disconnected from power source. Failure to comply may cause serious injury.

The VBS-1610 Band Saw is rated at 400V and without plug.

You may connect a proper plug suitable for 400 volt operation, or "hard-wire" the machine directly to your electrical panel provided there is a disconnect near the machine for the operator.

The band saw must be grounded. A qualified electrician can make the proper electrical connections and confirm the power on site is compatible with the saw.

Before connecting to power source, make sure switch is in off position.

6.1 Three-phase test run

After wiring the band saw, you should check that the wires have been connected properly. Connect machine to power source and turn it on for an instant to watch direction of blade movement.

If blade runs upward instead of downward, disconnect machine from power, and switch any two of the three leads in the motor junction box (see section 18.0, Electrical diagram).

5.0 Installation

1. Remove three (3) nuts and washers holding band saw to shipping crate bottom.

2. Use the lifting ring to lift band saw into its permanent location. For best performance, band saw should be bolted to floor after a level position has been found.

3. Using a square, adjust table 90 degrees to blade, both front to back and side to side. Loosen the hex cap screws below the table to move it and tighten to hold table in place. If necessary, adjust the pointers to zero should they read different once table is perpendicular to blade in both directions.

4. To level the machine, place a machinist's level on the table and observe in both directions.

5. Use metal shims under the appropriate hold down screw. Tighten screw and recheck for level.

6. Adjust with additional shims, as required, until table is level when all mounting screws (or nuts) are tight.

8.0 Adjustments

All adjustments or repairs to

machine must be done with power off and machine disconnected from power source. Failure to comply may cause serious injury.

8.1 Blade tensioning

1. Raise upper blade guide by loosening lock knob (A, Figure 7) and lifting blade guide handle (B, Figure 7) to its highest position.

Figure 8

8.2 Blade tracking

Blade tracking may be required periodically depending upon blade size and tension. The blade must be tensioned as outlined in section 9.1 Blade tensioning. Disconnect machine from power source and open upper blade wheel door. Shift high-low gear box lever into neutral position. Turn upper blade wheel by hand while observing blade position on upper blade wheel. If adjustment is necessary:

1. Turn blade tracking knob (E, Figure 8) clockwise to track blade toward front of blade wheel.

2. Turn tracking knob counterclockwise to track blade toward rear of blade wheel. Blade should run next to, but not against, the wheel flange.

Note: Upper and lower blade guides should be moved away and left loose from the blade while tracking adjustments are being made.

8.3 Blade guide adjustment

Figure 7

2. Apply finger pressure to blade. Travel from vertical should be approximately 10mm each way.

3. To tighten blade, turn handwheel (C, Figure 7) clockwise. To loosen blade, turn handwheel counterclockwise.

4. Use blade tension indicator (D, Figure 8) as reference only. Blade should be tensioned using the finger pressure method.

Blade guides must be properly

adjusted or damage may occur to blade and/or guides.

Guard has been removed to

show detail. Always operate saw with guard in place and properly adjusted. Failure to comply may cause serious injury.

Blade guide adjustment has been set by the manufacturer. Should future adjustment be needed, proceed as follows.

1. Loosen upper blade guide lock knob and raise guide assembly to half-way between table and head, then tighten lock knob

2. Loosen two set screws (F, Figure 9) and adjust guide so that blade guides are in back of saw teeth. Blade guides must be adjusted far enough back to clear saw blade even during cutting operation when the blade is deflected toward the rear.

3. Tighten the two screws (F, Figure 9).

4. Open upper access door and rotate blade wheel by hand until weld portion of blade is between the two fingers.

5. Loosen two socket head cap screws (G, Figure

9) and adjust each finger toward the blade. They should not touch the blade. Adjust for

0.25mm clearance on either side.

6. Retighten the two screws (G, Figure 9) once proper adjustment has been made. Be sure that adjustment for air nozzle has not changed and it directs the flow of air to the cut.

Figure 9

7. Adjust lower blade guides in similar manner.

Note: Even properly adjusted blade guides will show wear after continual use. Readjust as necessary. If the blade guides become difficult to adjust, switch the left and right blade guides.

8.4 Top guide adjustment

Always position top guide to within 3mm of the top surface of workpiece. This minimizes exposure of operator’s hands to the saw blade.

8.5 Changing saw blades

7. Tension blade by turning tension handwheel. Rotate wheel by hand and make sure blade is properly seated in blade guides. Blade guides will have to be adjusted if the replacement blade is a different type and width.

8. Turn on saw and check blade tracking. Adjust tracking if necessary.

8.6 Work lamp

The work lamp uses a standard 20W/24V Halogen light.

9.0 Blade selection

Proper blade selection is just as important to band saw operation as is blade speed and material feed. Proper blade selection will impact blade life, straightness of cut, cut finish, and efficiency of operation. Excessive blade breakage, stripping of teeth, and waviness of cut are some of the results of improper blade selection.

Blades are classified by material composition, tooth shape, tooth pitch, tooth set, gage of the band material, and kerf of the set (width of cut).

9.1 Material composition

Carbon Steel – low cost, for use with non-ferrous materials, wood, and plastics.

High Speed Steel – resists heat generated by dry cutting. Used for ferrous metals.

Alloy Steel – tough and wear resistant, cuts faster with longer blade life. Used on hard materials. More expensive than carbon or high speed steel.

Carbide Tipped – for cutting unusual materials such as uranium, titanium, or beryllium.

1. Disconnect saw from power source.

2. Move upper blade guide to its highest position and lock in place.

3. Open both wheel doors. Turn tension adjustment handwheel counterclockwise to loosen tension on blade.

4. Remove blade from both wheels and maneuver it around blade guard on column and protective shield on upper blade guide. Use gloves when handling blades.

5. Install new blade by maneuvering around blade guard on column and protective shield on upper blade guide.

6. Place it between the fingers of both blade guides and onto both wheels. Position next to both wheel flanges. Make sure teeth point down toward table. NOTE: If teeth will not point downward regardless of blade orientation, the blade is inside-out. Twist blade outside-in and reinstall.

9.2 Tooth shape

Note: When cutting thin materials, the rule for blade pitch is to have a minimum of two teeth engaging the material being cut at all times.

Standard Tooth - generally used to cut ferrous metals, hard bronze, hard brass, and thin metals.

Skip Tooth - have better chip clearance (larger gullet) and are used on softer, non-ferrous materials such as aluminum, copper, magnesium, and soft brass.

Hook Tooth - provides a chip breaker and has less tendency to gum up in softer materials. Used in the same materials as skip tooth but can be fed faster than standard or skip tooth blades.

9.3 Set type

Straight Set – used for free cutting non-ferrous materials; i.e., aluminum, magnesium, plastics, and wood.

Wavy Set – used on materials of varying thickness (pipe, tubing, and structural shapes).

Raker Set – used in large cuts on thick plate and bar stock where finish of cut is not as important as speed.

9.4 Gage

Gage is the thickness of material from which the blade is produced. The thicker the material, the stronger the blade.

9.5 Kerf

Kerf is the width of a cut. Kerf will vary according to the set of the blade teeth.

10.0 Welder operation

Wear eye protection while

operating welder. Use care when handling blade after welding to avoid burns.

The welding procedure involves the following steps: Shearing the blade, grinding teeth to allow for the weld area, the actual welding, inspection of blade, annealing, grinding and a final inspection of blade. This procedure can be accomplished using the shear and welder assemblies on your band saw. Proceed as follows:

10.1 Shearing

9.6 Width

The thinner the blade, the tighter will be the minimum radius of cut. Always use widest blade possible for the job.

General rules for blade selection:  Select coarser pitch blades for thicker or softer

material.

 Select finer pitch blades for thinner or harder

material.

 Use fine pitch blades to obtain a smooth finish.  Use coarse pitch blades to obtain faster cutting

speeds (thick material).

 To prevent premature blade wear, use fastest

practical speed.

 Adjust feed rate to ensure continuous cutting

action.

 Run the bandsaw with blade centered in upper

and lower guides, and guide fingers adjusted as close as possible without touching the blade or weld joint.

Never adjust guide fingers

while blade is running. Failure to comply may cause serious injury.

9.7 Blade breakage

Band saw blades are subject to high stresses and breakage may sometimes be unavoidable. However, many factors can be controlled to help prevent most blade breakage. Here are some common causes for breakage:

1. Misalignment of blade guides.

2. Feeding workpiece too quickly.

3. Using a wide blade to cut a short radius curve.

4. Excessive tension.

5. Teeth are dull or improperly set.

6. Upper guides are set too high off the workpiece.

7. Faulty weld on blade.

Cut blade to longest length needed for band saw. Using the shear to cut your blade will ensure that cut ends are flat, square and smooth.

1. Place handle in upright position.

2. Position blade against back of square cutting guide of shear. See Figure 10. Make sure blade is held square with shear knife, so that cut will be square with blade.

Figure 10

3. Position blade so that cut is made at a place that allows for uniform spacing of teeth. See Figure

11.

4. Bring handle down firmly to cut blade.

IMPORTANT: If a blade has been cut by using snips, the ends of the blade must be ground square before welding them together, as shown in Figure 12.
