REFERENCE
PROCEDURE
A cold saw is a circular saw designed to cut metal which uses a toothed blade to transfer the heat generated by cutting to the chips created by the saw blade, allowing both the blade and material being cut to remain cool.
Saw Blade Head Assembly: The section of the machine composed of the saw motor, gear case, blade and blade guard, and feed handle and trigger switch.
Feed Handle: A long angled tube with a grip for raising and lowering the disk head and a trigger switch to start and stop the saw motor.
Gear Case: The central part of the assembly, housing the gear system. The motor mounts to the back and the output to the blade is to the left side.
Blade Guard: The Blade guard has a stationary cover which mounts to the left side of the gear case and a movable part which has linkage connect to it to cause the guard to open and expose the lower part of the blade as the feed handle is pulled downward.
Saw Blade: The saw blade is mounted onto the end of the arbor shaft and positioned to be centered within the guard assembly.
Electrical Box: The electrical box is mounted to the right of the saw blade head assembly and house the electrical control system except for the trigger switch.
Machine Base: A heavy cast iron structure that supports the miter system, vise system, head assembly, and holds the coolant system.
Vise: A clamping system that provides the basic support and grip for the work material. A handwheel opens and closes the vise jaws. From the operators position in front of the saw, the left side of the vise has the jaws to clamp the material. The right side bar provides support to reduce and prevent the material from kicking out at the end of the cut.
Material Stop: The material stop to the right side of the vise may be used to set the cut length of the material. This is especially useful for multiple cuts of the same length.
Support Roller: The support roller to the left or infeed side of the vise will assist in holding the material on plane with the vise table as well as assist in feeding the material through the vise.
Stand Support: structure for the machine head assembly, machine base, vise system, and coolant pump system.
Coolant Pump: Located within the rear of the machine base is a drawer-like self-contained coolant pump system, and includes a tank, pump, motor, filters, and hose.
Miter Angle
1. Push the miter lock lever to the left to release the disk head assembly.
2. Rotate the disk head assembly to the desired miter angle.
3. Use the indicator scale to set the desired cut angle. (Fine tune the angle as needed to get the exact angle.)
4. Pull the miter lock lever back to the right to lock in the angle. ALWAYS LOCK THE LEVER BEFORE CUTTING. 5. Adjust the vise clamping jaw to allow for the blade to clear the vise without contacting the jaw. Important: Never allow the saw to cut into the vise jaws.
6. Loosen the clamping bolt and slide the jaw left or right as needed to clear the saw blade. The jaw should be between 0.25” and 0.5” (6 – 13mm) without contacting the saw blade.
7. Adjust the clamping support to the right side of the blade by loosening and the mounting bolt and sliding the support within the slots or when needed, changing the slots.
Vise Operation
1. Use the hand wheel to open and close the vise jaw for pieces that vary in width.
a. Counter clockwise to open jaws
b. Clockwise to close jaws
2. Use the vise release lever to quickly clamp and unclamp pieces of the same width. The release lever is a 1/2 turn lever, from straight up (loosen) to straight down (clamped).
a. Clockwise to clamp the piece
b. Counter clockwise to unclamp the piece
Loading the Piece Part
1. Use the vise hand-wheel to open the jaws wider than the width of the piece.
2. Measure and mark off the length of material to be cut.
3. Place the piece on the flat surface in between the vise jaws.
4. Slide the piece through the jaws so the scribed length mark lines up with the blade or disk.
5. Push the piece up against the back vise jaw.
6. Turn the hand-wheel clockwise to clamp the piece.
If repetitive cuts are required for material of the same width:
1. Turn the vise hand-wheel clockwise to approach the piece part, leaving approximately 3/16” (5mm) gap between front jaw and the piece part.
2. Then use the vise lock lever to clamp and unclamp the piece.
Setting Cut Length Setting the cut length eliminates measuring duplicate pieces.
1. Measure and mark the length of material to be cut off.
2. Load the piece part.
3. Line up the cut.
4. Clamp the piece part.
5. Loosen the hex nut at the base of the bar riser.
6. Slide the bar riser (A) along the long rod so that the tip of stop bar touches the end of the piece part.
7. Tighten the hex nut at the base of the bar riser.
Using the stop bar
1. Cut off the first length from the clamped piece part.
2. Unclamp the piece part.
3. Slide the piece part forward until it reaches the tip of the stop bar.
4. Clamp the piece part.
5. Proceed with the cutting cycle.
Cutting Operation Cycle
1. Set the miter cut angle.
2. Open the vise jaws.
3. Load and clamp the piece part.
4. Adjust the bar stop for cutting length.
5. Press button to turn power on to the saw.
6. Set the coolant switch to on.
7. Grasp the feed handle.
8. Press the trigger switch to start blade motor.
9. Pull down the feed handle applying a steady and constant pressure.
10. After cut-off, raise feed handle slowly.
11. Release the trigger switch to stop the blade motor.
12. Use vise lever to open the jaws.
13. Remove or advance the piece part forward for next cut.
14. To turn off machine power press the stop button.
15. To stop machine in an emergency situation, press the EMERGENCY STOP button.
16. Before restarting machine, emergency stop button must be reset with a clockwise twist.
CHOOSING A SAW BLADE
A general-purpose blade is intended to allow for the saw to make cut as soon as it is safely set up and ready for operation. While this blade will cut many material profiles, the best cutting results will be achieved using a blade which is chosen to match the material to be cut. To achieve a quality and efficient saw cut, the following points must be taken into consideration:
• Type of material being cut (ferrous or non-ferrous)
• Material hardness and physical dimensions
• Blade descent rate
• Rotational speed of blade
• Blade tooth profile Choose a tooth pitch that is suitable for the workpiece.
Thin walled profiles, including tubes and pipes require close toothing. At least 3-6 teeth should be in contact with the material while cutting.
Large solid or transverse sections require widely spaced toothing to allow for greater volume of chips and better tooth penetration. Soft materials such as plastics, light alloys, mild bronze, Teflon, wood, etc., require widely spaced toothing to avoid clogging.
Blade Selection Chart
TROUBLESHOOTING
On average, a typical cold saw blade should last at least six months. Damaged teeth. Typically, a cold saw blade can complete between 800 to 1000 cuts before totally wearing out.
Metal Chip Indicators
Chips are the best indicator of correct material feed force. Monitor chip information and adjust feed accordingly.
• Thin or Powdered Chips – increase feed rate or reduce saw speed
• Burned Chips – reduce feed rate and / or saw speed
• Curly Silvery and Warm Chips – optimum feed rate and saw speed
