Lathe MountedAutomatic UndercutterThe CU Automatic Lathe Mounted Undercutter is
designed specifically for shops rebuilding DCmotors. The undercutter attaches directly to your existing lathe
and automatically undercuts the mica in less time thanmanual methods. It not only works faster, the CU sys-tem also reduces the amount of finish work because ofthe precise cutting action of the saw and floating spin-dle.
The CU Automatic Undercutter uses laser technologyto precisely position the cutting saw for accurate micaremoval. Manual methods rely on the operator’s skilland ability to visually align the cutter in the slot. Thefloating spindle of the CU follows skew in the mica slot,and the climb cut rotation of the saw produces smoothcuts requiring less clean-up.
The CU Automatic Undercutter pays for itself in a shorttime by reducing the man hours needed for completemotor rebuilding. Set up is fast, and the operator is freeto complete other tasks during the undercutting opera-tion. The CU increases the efficiency of your shop andimproves the quality of the finished armatures.

To justify the investment in this equipment, simply compare the labor to set up the undercutter to the total labor presently spent on manual undercutting.The set-up time for this undercutter is short compared to the several hours that can be spent hand undercutting a large commutator. This undercutter ’sconsistent results may also help reduce clean-up time.
This tool is intended to be used on lathes that swing armatures at least 16” (406mm) diameter. If the lathe does not have this swing, it may still be pos-sible to modify the unit to make it fit.
The unit can be set-up quickly as it has basically 3 components.
1. The UL Undercutting Head that fits in the lathe T-slot. The base of the undercutting head is man-ufactured to fit one lathe. Additional adapters can be made for other lathes you may havein house.
2. The Indexing Attachment that fits over the bedways. The enduser sends a data chart showing dimensions of the lathe bedways so the base of the attachment can be made to mount easily on the lathe.
3. The Control Console on its own pedestal. The console can be moved next to the lathe when needed.
