JH Universal Commutator Repair Machine

Commutator Turning, Automatic Undercutting & Deburring All in One Machine!

Saves Time – Improves Quality & Reduces Armature Handling!

Now there is a stand-alone, multi-functional, universal commutator processing machine for turning and facing commutators that automatically undercutting mica slots and deburring and polishing armatures in three easy steps. CAM’s new commutator turn and undercut machine greatly reduces armature handling and speeds process time by eliminating the need to move armatures back and forth between single function machines. Designed specifically for shops that handle small to medium sized armatures, the JH is ideal for servicing small DC motors and those used in transit and light rail systems.

   • World’s first universal commutator processing machine!
   • Saves shop lathe for other work.
   • Uses the latest technology to produce high quality, repeatable results.

Step 1: Turning & Facing

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 setup. The machine’s spindle speed is variable up to a maximum of 300 rpm.

Step 2: Automatic Mica Undercutting with Optical Sensor Technology

The JH Universal Armature Machine has all of the features found in our top-of-the-line automatic undercutters including: a programmable controller, retractable spindle, 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.

Step 3: Brush Deburring & Polishing

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.
