Ammco 6936 Cross Feed Extension User Manual download pdf

The Cross Feed Extension is used to increase the

capacity of the twin cutter to machine large diameter

brake discs on the standard Model 4000 and 4100 Brake

Lathes.

The placement of the twin cutter on the Cross Feed

Extension is determined by the diameter of the rotor to

be machined: Use hole A to increase the rotor diameter

by 2 1/4", hole B to increase by 4 1/4" and hole C to

increase by 5 1/2".

Mounting Instructions

Referring to the illustration, remove the cross feed lock-

ing stud and clean all surfaces of chips. Mount the Cross

Feed Extension plate directly on the cross feed with Part

# 925271 1/2" x 2" Hex Socket Flat Head Screw — for

cross feeds

with

a recess. Use Part # 925270 1/2" x 1"

Insert the # 911222 locking stud (with the # 911227 nut

and washer assembly) through the twin cutter and into
