OPERATIONS

MAKING THE CUT

After clamping the workpiece securely in the vise, turn the machine on and allow the motor to come up to full speed. Lower the wheel (A) lightly until it comes into contact with the workpiece (B), as shown in Fig. 17.

Do not allow the wheel to chatter and jump as this may cause the wheel to wear out of round, resulting in poor quality cutting and possible broken wheels.

Continue to push firmly down on the handle while the cut is being made, as shown in Fig. 18.

When coming through the bottom of the cut, as shown in Fig. 19, do not slow up. This keeps the metal from overheating and dragging off in a heavy burr.

Fig. 20 illustrates the cut-off piece after the cut is completed. NOTE: The number of cuts per wheel, as well as the quality of cut, may vary considerably with the cutting time. Fast cuts cause the wheel to wear more rapidly but also help to reduce discoloration and burr.
