Unimat DB 200 or SL 1000 Chuck & Accessory Backing or Mounting Plate Plate. 1001/01
This backing plate is New, Never Used.
When purchased new, 3 Jaw Chucks Nos. 1001, and Polishing Arbor # 1030 included a separate threaded mounting plate which is supplied over-sized and was supposed be turned down slightly to fit the back of the chuck or accessory. This was to achieve perfect concentricity.
Easy to do, this simple machining operation MUST be performed on the same Unimat lathe on which the chuck will be used, to ensure a true and concentric running accessory.
These Mounting Plates are useful for your 3 jaw chuck if the mounting plate on it was turned on another machine. Also very useful for mounting special arbors, chucks or fixture plates onto the Unimat.
This will also fit the Round T-Slotted Fixture Plate #1261
Comes with two set's (1 set long, 1 set short) of the special screws needed as shown.
