| JHT– Large Universal Commutator Repair Machine |
Commutator Turning, Automatic Undercutting & Deburring
All in One Machine! |
 |
Multi-Function Machine, Uses Innovative, Smart Technology to Improve Work Quality &
Shop Productivity!
CAM's new commutator Turn & Undercut machines greatly reduce armature handling and speed process time by eliminating the need to move armatures back and forth between single function machines. Designed specifically for shops that handle medium to large sized armatures, the JHT is ideal for servicing DC traction motors, mining and mill motors used in many industrial applications.

#1 Commutator Turning & Facing
The quick change commutator turning attachment mounts on the machine's tool post. Once the tool set-points and carriage feed rates are determined they can be easily programmed and stored in memory for repeatable set-up.
 Easy, Fast
Recipe Set-Up
with program storage capacity for up to 20 armature types ensures optimal performance
every time!

#2 Automatic Mica Undercutting with
Fiber Optic Indexing Technology
This Universal Armature Machine has all of the features found in our top-of-the-line Automatic Undercutters including: a programmable controller, retractable spindle, fiber optic 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 for faster process time and extended saw life.
|
#3 Brush Deburring
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.
Brush Deburring takes only 15 minutes, is more consistent than hand chamfering and is better for the motor!
