INTRODUCTION

About This Machine

For Machines Mfg. Since 8 /09

Capabilities

This metal cutting bandsaw uses a gravity-fed blade to make straight cuts through workpieces that are clamped in a vise. Since the workpiece is secured and remains stationary while the blade lowers automatically, accuracy and operator safety are maximized.

The vise on the Model SB1020 is capable of holding rectangular stock up to 9" x 12" and round stock up to 10".

After a cut is complete, the OFF switch is triggered and the motor automatically turns off.

Features

In addition to its capabilities, the Model SB1020 has several features to increase versatility and efﬁciency.

The headstock can be rotated to make angled cuts from -45°–60° while variable blade speeds ensure that the proper cutting speed is available for a variety of workpiece sizes and materials.

Both the downfeed rate and pressure are adjustable for ﬁne-tuning each cutting operation and an adjustable auto-OFF power switch maximizes safety and minimizes energy use by turning the machine off at the end of every cut.

A ﬂood coolant system, comprised of a coolant tank and pump in the machine base and an adjustable nozzle at the blade provide adequate coolant for optimum cutting efﬁciency and blade life.

A storage compartment in the cabinet base provides a convenient location for keeping spare blades or other accessories and the transport handle makes moving the machine easy.

SAFETY

Additional Metal Bandsaw Safety

For Machines Mfg. Since 8 /09

1. Blade Condition. A dull or damaged

blade can break apart during operation, increasing the risk of operator injury. Do not operate with a dull, cracked or badly worn blade. Inspect the blade for cracks or missing teeth before each use.

2. Hand Placement. Hands could be cut

by the blade or crushed when lowering the headstock. Never position ﬁngers or thumbs in line with the cut or under the headstock while it is moving.

3. Blade Guard. Hands and ﬁngers can easily

be cut by the bandsaw blade. To reduce the risk of laceration injuries, do not operate this bandsaw without the blade guard in place.

4. Starting Position. To reduce the

likelihood of blade breakage and possible entanglement, never turn the saw ON with the blade resting on the workpiece.

6. Workpiece Handling. A shifting workpiece

can result in impact or laceration injuries. To reduce the risk of injury, always securely clamp the workpiece in the vise and use additional support ﬁxtures if needed. Never hold the workpiece with your hands during a cut. Flag long pieces to reduce the risk of tripping over them.

7. Power Interruption. Unplug the machine

and turn the power switch OFF after a power interruption. If left plugged in and turned ON, this machine will start up when power is restored, resulting in possible entanglement, laceration, or amputation hazards.

8. Hot Surfaces/Sharp Edges. Due to the

cutting process, a freshly cut workpiece, chips, and some machine components can be hot enough to burn you and sharp enough to cut you. Allow components to cool and use safe handling methods to reduce the risk of these injuries.

5. Blade Replacement. The blade can only

make a safe and efﬁcient cut if the teeth are facing the workpiece. When replacing blades, make sure the teeth face toward the workpiece. Wear gloves to protect hands and safety glasses to protect eyes.

9. Moving Blade. A moving bandsaw blade

presents a serious risk for laceration or amputation injuries. Always allow the blade to come to a complete stop before mounting or repositioning a workpiece in the vise. Never touch a moving blade.

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed.

To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by a qualified electrician in accordance with all applicable codes and standards.

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result—especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

The unpainted surfaces are coated at the factory with a heavy-duty rust preventative that prevents corrosion during shipment and storage. The beneﬁt of this rust preventative is that it works very well. The downside is that it can be time-consuming to thoroughly remove.

Be patient and do a careful job when cleaning and removing the rust preventative. The time you spend doing this will reward you with smooth-sliding parts and a better appreciation for the proper care of the unpainted surfaces.

Although there are many ways to successfully remove the rust preventative, we have cleaned thousands of machines and found the following process to be the best balance between efﬁciency and minimized exposure to toxic fumes or chemicals.

Before cleaning, gather the following:

• Disposablerags

• Cleaner/degreaser (certain citrus-based

degreasers work extremely well and they have non-toxic fumes)

• Safetyglasses&disposablegloves

Note: Automotive degreasers, mineral spirits, or

WD•40canbeusedtoremoverustpreventative.

Weight Load

Refer to the Machine Speciﬁcations for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual.

Physical Environment

The physical environment where your machine is operated is important for safe operation and longevity of parts. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous or flammable chemicals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature is outside the range of 41°– 104°F; the relative humidity is outside the range of 20–95% (non-condensing); or the environment is subject to vibration, shocks, or bumps.

Electrical Installation

Place this machine near an existing power source. Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave access to a means of disconnecting the power source or engaging a lockout/tagout device.

Lighting

Lighting around the machine must be adequate enough that operations can be performed safely. Shadows, glare, or strobe effects that may distract or impede the operator must be eliminated.

Children or untrained people may be seriously injured by this machine. Only install in an access restricted location.

Leveling machinery helps precision components, such as bed ways, remain straight and ﬂat during the lifespan of the machine. Components on an unleveled machine may slowly twist due to the dynamic loads placed on the machine during operation.

For best results, use a precision level that is at least 12" long and sensitive enough to show a distinct movement when a 0.003" shim (approximately the thickness of one sheet of standard newspaper) is placed under one end of the level.

See the ﬁgure below for an example of a high precision level.

We strongly recommend securing your machine to the floor if it is hardwired to the power source. Consult with your electrician to ensure compliance with local codes.

Generally, you can either bolt your machine to the ﬂoor or mount it on machine mounts. Although not required, we recommend that you secure the machine to the ﬂoor and level it while doing so. Because this is an optional step and ﬂoor materials may vary, hardware for securing the machine to the ﬂoor is not included.

Lifting & Moving

This machine and its parts are heavy! Serious personal injury may occur if safe moving methods are not used. To reduce the risk of a lifting or dropping injury, ask others for help and use power equipment.

Unbolt the machine from its pallet, then insert two round steel bars through the lifting holes in the machine base. Attach lifting straps and hooks to the bars as shown in Figure 6. Lift the machine just high enough to clear the pallet, then move it to its final location. Have an assistant stabilize the machine while moving.

Lag Screw

and Anchor

Anchor

Stud

Lag screws and anchors, or anchor studs (below), are two popular methods for securing machinery to a concrete ﬂoor. We suggest you research the many options and methods for securing your machine and choose the best one for your speciﬁc application.

Machine mounts are rubber pads mounted to a threaded stud, which can be fastened to the bottom of the machine.

Machine mounts offer certain advantages such as ease of installation, vibration dampening, and easy leveling. They also make it easier to relocate the machine later on.

The disadvantage of machine mounts is that the machine can shift or move over time. For this reason, electrical codes may limit their use if the machine is hardwired to the power source. Also, mounts may reduce the total surface area of machine-to-floor contact, depending on the design of the machine.

OPERATION

Blade Selection

Selecting the right blade for the cut requires a knowledge of various blade characteristics. This section breaks down blade characteristics to help the reader make an informed decision about what blade to use for a given operation.

Blade Terminology

For Machines Mfg. Since 8 /09

Tooth Rake: The angle of the tooth face

from a line perpendicular to the length of the blade.

Gullet Depth: The distance from the tooth

tip to the bottom of the curved area (gullet).

Tooth Pitch: The distance between tooth

tips.

Blade Back: The distance between the bot-

tom of the gullet and the back edge of the blade.

Blade Pitch or TPI: The number of teeth per

inch measured from gullet to gullet.

Blade Length

Measured by the blade circumference, blade lengths are usually unique to the brand of your bandsaw and the distance between the wheels.

Figure 16. Bandsaw blade terminology.

A. Kerf: The width of the cut made during op-

eration.

Tooth Set: The distance each tooth is bent

left or right from the blade.

Gauge: The thickness of the blade.

Blade Width: The widest point of the blade

measured from the tip of the tooth to the back edge of the blade.

Model Blade Length

SB1020 .......................................................... 108

⁄4"

Blade Width

Measured from the back of the blade to the tip of the blade tooth (the widest point), blade width is often the ﬁrst consideration given to blade selection. Blade width dictates the largest and smallest curve that can be cut, as well as how accurately it can cut a straight line—generally the wider the blade, the straighter it will cut.

OPERATION

Tooth Set

Three common tooth sets are alternate, wavy, and raker (see Figure 17). Each removes material in a different manner to make the kerf in the workpiece.

Figure 17. Bandsaw blade tooth sets.

Alternate: An all-purpose arrangement with

teeth bent evenly left and right of the blade. Generally used for milder metals.

Wavy: Generally three or more teeth in a group

that are bent one way, followed by a non-set tooth, and then a group bent the other way. Recommended for straight cuts in thin metals or thin-wall tubing.

Raker: Three teeth in a recurring group—one

bent left, next one bent right, and then a nonset tooth. The raker set is ideal for most contour cuts.

Tooth Type

The most common tooth types are described below and illustrated in Figure 18. Each removes, gathers, and expels material differently.

Figure 18. Bandsaw blade tooth types.

Variable Pitch (VP): Varying gullet depth and

tooth spacing, a "0" rake angle, excellent chip removing capacity, and smooth cutting.

Variable Pitch with Positive Rake: Varying

gullet depth and tooth spacing, a positive rake angle, better chip formation, and aggressive cutting.

Hook or Claw: Wide gullets (round or flat),

equally spaced teeth, positive rake angle, and fast cut with good surface finish.

Skip or Skip Tooth: Wide, flat gullets, a "0" rake

angle, equally spaced teeth, and recommended for non-ferrous materials.

Standard or Raker: Equally spaced teeth set at

a "0" rake angle. Recommended for all purpose use.

Blade Pitch (TPI)

The chart below is a basic starting point for choosing teeth per inch (TPI) for variable pitch blades and standard raker set bi-metal blades/ HSS blades. However, for exact speciﬁcations of bandsaw blades that are correct for your operation, contact the blade manufacturer.

To select the correct blade pitch:

1. Measure the material thickness. This

measurement is the distance from where each tooth enters the workpiece to where it exits the workpiece.

2. Refer to the "Material Width/Diameter" row of the blade selection chart in Figure 19, and read across to find the workpiece thickness you need to cut.

Material Width/Diameter

Material Shapes

3. Refer to the "Material Shapes" row and find

the shape of the material to be cut.

4. In the applicable row, read across to the

right and find the box where the row and column intersect. Listed in the box is the minimum TPI recommended for the variable tooth pitch blades.

5. The "Cutting Speed Rate Recommendation"

section of the chart offers guidelines for various metals, given in feet per minute (FPM). Choose the speed closest to the number shown in the chart.

OPERATION

Blade Changes

Change blades when they become dull, damaged, or if the operation requires a different type of blade.

To change the blade on the bandsaw:

1. DISCONNECT BANDSAW FROM POWER!

2. Raise the head of the bandsaw, then remove

the blade cover.

3. Loosen the tension knob and slip the blade off of the wheels.

Figure 21. Blade cutting direction.

4. Install the new blade through both blade

guides, as shown in Figure 20, and around the bottom wheel.

Figure 20. Typical blade installation.

5. Hold the blade around the bottom wheel

with one hand and slip it around the top wheel with the other hand, keeping the blade between the blade guides.

Note: It is sometimes possible to ﬂip the

blade inside out, in which case the blade will be installed in the wrong direction. Check to make sure the blade teeth are facing toward the workpiece, as shown in Figure 21, after installing it on the bandsaw. Some blades will have a directional arrow you can use as a guide.

6. When the blade is around both wheels,

adjust the position so the back of the blade is against the wheel shoulder, as shown in Figure 22.

blade selection

Blade Tension

Proper blade tension is essential to avoid blade vibration, twist, or`slippage on the wheels. A correctly tensioned blade provides long life, straight cuts, and efficient cutting times.

The three major signs of incorrect blade tension are: 1) The blade stalls in the cut and slips on the wheels, 2) the blade frequently breaks, and 3) the bandsaw does not make straight cuts.

To tension the blade on the bandsaw:

1. Make sure the blade is tracking properly.

2. DISCONNECT BANDSAW FROM POWER!

3. Loosen and slide the blade guide as far out

as it will go, then tighten it down again.

4. Turn the tension knob in Figure 23 clockwise to tighten the blade or clockwise to loosen the blade.

Tension

Gauge

Blade Breakage

Many conditions may cause a bandsaw blade to break. Some of these conditions are unavoidable and are the natural result of the stresses placed on the bandsaw; other causes of blade breakage are avoidable.

The most common causes of avoidable blade breakage are:

• Faulty alignment or adjustment of the blade guides.

• Forcing or twisting a wide blade around a tight radius.

• Feeding the workpiece too fast.

• Dull or damaged teeth.

• Over-tensioned blade.

• Top blade guide assembly set too high above

the workpiece. Adjust the top blade guide assembly so that there is approximately

⁄8"–1⁄4" between the bottom of the assembly and the workpiece. Understand that with smaller workpieces, this may not be possible. In these cases, simply adjust the blade guide as far down as possible.

Blade

Tension

5. Tighten the blade until the tension gauge

moves into the green section.

-24-

• Using a blade with a lumpy or improperly finished braze or weld.

• Continuously running the bandsaw when not in use.

• Leaving the blade tensioned when not in use.

• Using the wrong blade pitch (TPI) for the

workpiece thickness. The general rule of thumb is to have no fewer than three teeth in contact with the workpiece when starting a cut and at all times during cutting.

OPERATION

Blade Care & Break-In

Blade Care

To prolong blade life, always use a blade with the proper width, set, type, and pitch for each application. Maintain the appropriate feed rate, feed pressure, and blade speed and pay attention to the chip characteristics (Refer to the Chip Inspection Chart on Page 26). Keep your blades clean, since dirty or gummed up blades pass through the cutting material with much more resistance than clean blades, causing unnecessary heat.

Blade Break-In

The tips and edges of a new blade are extremely sharp. Cutting at too fast of a feed rate or too slow of a blade speed can fracture these tips and edges, quickly dulling the blade. Properly breaking-in a blade allows these sharp edges to wear without fracturing, thus keeping the blade sharp longer. Below is a typical break-in procedure. For aftermarket blades, refer to the manufacturer's break-in procedure to keep from voiding the warranty.

Use the Chip Inspection Chart on Page 26 as a guide to evaluate the chips and ensure that the optimal blade speed and feed rate are being used.

To properly break-in a new blade:

1. Choose the correct speed for the blade and

material of the operation.

2. Reduce the feed pressure by half for the first

50–100 in

of material cut.

Downfeed Rate

Start and stop downfeed with the downfeed knob. The downfeed rate is adjusted by turning the downfeed rate adjust knob (Figure 24). Turning the knob clockwise decreases the downfeed rate and turning the knob counterclockwise increases the downfeed rate.

Downfeed Pressure

The downfeed pressure is controlled by the spring shown in Figure 25.

To decrease downfeed pressure, turn the cap screw clockwise to increase spring tension.

To increase downfeed pressure, turn the cap screw counterclockwise to release spring tension.

3. To avoid twisting the blade when cutting,

adjust the feed pressure when the total width of the blade is in the cut.

Blade Speed Chart

The chart in Figure 26 offers blade speed guidelines for various metals, given in feet per minute (FPM) and meters per minute (M/Min). Choose the closest available speed on the machine, then adjust the feed rate as necessary, using the appearance of the chips produced as a guide. Refer to the Chip Inspection Chart that follows for recommendations on adjusting feed rate or blade speed based on the appearance of the chips produced.

Figure 26. Dry cutting blade speed chart.

Chip Inspection Chart

The best method for choosing the cutting speed and feed rate for a cutting operation is to inspect the chips created by the cut. These chips are indicators of what is commonly referred to as the "chip load." Refer to the chip inspection chart below to evaluate chip characteristics and determine whether to adjust feed rate/pressure, blade speed, or both.

OPERATION

Cutting Fluid

While simple in concept and function, many issues must be taken into account to find and use the correct cutting fluid. Always follow all product warnings and contact the f luid manufacturer for unanswered questions.

Use the information below as a guideline to choose the appropriate cutting fluid. Always refer to the cutting fluid manufacturer for specific application and safety information:

• Forcuttinglowalloy,lowcarbon,and

general-purpose category metals with a bi-metal blade —use a water soluble cutting fluid.

• Forcuttingstainlesssteels,highcarbon,and

high alloy metals, brass, copper and mild steels—use "Neat Cutting Oil" (commonly undiluted mineral oils) that have extreme pressure additives (EP additives).

Cutting Fluid System

This bandsaw has a built-in cutting fluid system that extends the life of your bandsaw blades by lowering the temperature of the blade and workpiece and washing away chips.

To use the cutting ﬂuid system:

1. Thoroughly clean and remove any foreign

material that may have fallen inside the reservoir during shipping.

2. Place the filter screen and drain tube in the reservoir as shown in Figure 34.

Drain

Tube

• For cutting cast iron, cutting fluid is not recommended.

Remember: Too much flow at the cutting fluid nozzles will make a mess and can make the work area unsafe; and not enough fluid at the cut will heat the blade, causing the blade teeth to load up and break.

Tip: Using a refractometer or hydrometer to replenish water in water-based coolant can extend the life of blades and coolant, and ensure consistent cutting results.

BIOLOGICAL AND POISON HAZARD! Use proper personal protection equipment when handling cutting fluid and follow federal, state, and fluid manufacturer requirements to properly dispose of cutting fluid.

Low

Figure 34. Filter screen and hose.

3. Fill the reservoir to the "high" mark with

your chosen cutting fluid solution.

Magnesium fires are extremely dangerous! When cutting magnesium, always use a cutting fluid intended for this type of metal and carefully follow the fluid manufacturer's recommendations.

Machine Storage

All machinery will develop serious rust problems and corrosion damage if it is not properly prepared for storage. If decommissioning this machine, use the steps in this section to ensure that it remains in good condition.

To prepare your machine for storage or decommission it from service:

1. DISCONNECT BANDSAW FROM POWER!

2. Thoroughly clean all unpainted, bare metal

surfaces, then coat them with a light weight grease or rust preventative. Take care to ensure these surfaces are completely covered but that the grease or rust preventative is kept off of painted surfaces.

If the machine will be out of service for only

a short period of time, use a quality mediumweight machine oil (not auto engine oil) in place of the grease or rust preventative.
