    The witness marks must be carefully aligned when installing the arbor （Figure 3）. 1. Locate the witness marks on the arbor and the spindle. Figure 3-Align witness marks during arbor installation 2. Insert the arbor into the spindle making sure the witness marks are aligned.

  • Page 14: Basic Operation

    Basic Operation To completely understand drum and rotor turning you must have knowledge of the lathe itself. Spindle The spindle is a motor driven shaft that turns the arbor upon which the brake drum or rotor is mounted. By turning the drum and holding a cutting tool against the inner braking surface, metal can be removed.

  • Page 15: Cross Feed

    1. Release the belt tension by moving the V-belt adjusting lever to the right (clockwise). 2. Move the belt to the pulley groove that will give the correct spindle speed for the cut to be taken. 3. Reapply tension to the V-belt by moving the adjusting lever back to the operating position.

  • Page 16: Basic Operation Of Handwheels

    Basic Operation of Handwheel Clockwise rotation of the spindle feed handwheel retracts the spindle in towards the lathe. Clockwise rotation of the cross feed handwheel moves the cutting tool in towards the lathe. Figure 9-Clockwise rotation of handwheel Counterclockwise rotation of the spindle feed handwheel extends the spindle out away from the lathe.

  • Page 17: Mounting Drums

    Note: most often, the discard diameter is cast into the brake drum, not the maximum machining diameter. 3. Inspect brake drum. do not attempt to machine a drum that is damaged or in poor condition. Mounting Drums 1. Loosen the boring bar clamp nut and push the boring bar all the way into the clamp.
  • Page 18 6. Turn the drum by hand to make sure that everything is clear. 7. Turn the lathe ON. 8. Advance the tool bit manually until it just contacts the drum surface momentarily and makes a scratch cut. Figure 14 - First scratch cut 9.
  • Page 19 12. Turn the spindle feed handwheel 1/2 turn in either direction and make a second scratch cut. No change the drum diameter. Figure 16-Second scratch cut 13. Turn the lathe OFF. 14. Examine the scratch cuts. If the first and second cuts are opposite one another (180°apart), fix wrong, remove the drum from the arbor, check the mounting adapters and arbor for nicks, burrs, or chips, remount the drum , and repeat scratch cut process.

    until the cutter move to the drum outside. Turn off the drum/rotor switch and spindle motor switch. 21. Spindle feed speed should be adjusted by feed timing potentiometer. High speed used to roughing cut, low speed used to finish cut. NOTE: Refer to rotor diameter to find spindle speed and feed speed.

  • Page 21: Twin Cutters

    Twin Cutters Twin cutters can cut two surfaces of disc. Figure 20 – fix twin cutters Rotor Mounting Review the descriptions of mounting a brake drum on page 6. The same directions apply when mounting a brake rotor. Spacers are used to fill out the arbor shaft so that the arbor nut can be tightened.

  • Page 22: Set Up And Reconditioning Rotors

    Set Up and Reconditioning Rotors 1. Install a silencer band on the mounted rotor. Stretch the band around the rotor and hook the metal loop over a lead weight. Figure 22 – Attach silencer band 2. Center the twin cutter to the rotor. The twin cutter should be approximately parallel to the lathe spindle.
  • Page 23 8. When the tool bits make contact, rotate each of the inner depth-of-cut collars to zero and back the tool bits away from the rotor. Figure 25 – Tool bit controls 9. Turn the cross feed handwheel until the tool bits are at mid-point of the rotor face.
  • Page 24 Figure 28 – Second scratch cut 12. If the scratch cuts are side; the run out or wobble is caused by rotor condition. A centesimal meter may be used to compare rotor run out with manufacturer's specifications. 13. If the scratch cuts are opposite one another (180°), the rotor may not be properly mounted on the arbor.

  • Page 25: Typical Adapter Usage For Rotors

    Typical Adapter Usage for Rotors Before you begin It is important in any machining operation that all adapters and mounting hardware, as well as disc to be machined, are clean and free of nicks. IMPORTANT: The flange plate must contact the flat portion of the disc, but must not contact the rotor anywhere around the outside radius.

  • Page 26: Maintenance And Service

    Referring to the illustration, remove the cross feed locking stud and clean all surfaces of chips. Mount the cross feed extension plate directly on the cross feed seat. Insert the locking stud (with nut and washer assembly)through the cross shelves joint cross feed extension. Hand tightens the stud using the knurled head.

  • Page 27: Cleaning

    Use a hand pump grease gun only when cross feed grease fitting. A high pressure gun can burst the lathe casting. Figure 34 – Cross feed grease fitting Grease the feed screw pole monthly. Locate the feed screw pole by pulling the protective boot back.
