Step 1 - Turning & Facing   Step 2 - Automatic Mica Undercutting with Laser Indexing Technology   Step 3 - Brush Deburring & Polishing
The JH's quick change commutator turning attachment mounts on the machine's tool compound. Once commutator turning set-points and carriage speed rates are determined they can be easily programmed and stored in memory for repeatable set-up.

The machine's spindle speed is variable up to a maximum of 500 rpm.
  The JH Combination Armature Machine has all of the features found in our top-of-the-line Automatic Undercutters including: a programmable controller, retractable spindle, laser mica slot sensor and automatic armature indexing. The floating spindle follows skewed mica eliminating constant operator adjustments. On the return stroke the spindle retracts out of the mica slot speeding process time and extending saw life.   CAM's patented Brush Deburring Attachment eliminates tedious and time consuming hand chamfering of each mica slot and speeds clean up. Just slide the attachment onto the JH tool post and the JH will automatically follow the deburring recipe for each armature type.
