Fig. 19.7 Split-sheave eccentric

A circular hole is provided at the centre of the block for holding the cylindrical portion of

the nut 4. An adjusting screw 8 passes through the nut and is held to the body by means of a

bearing plate 6.

By operating the adjusting screw, the slide block is made to move along with the tool holder

on the body. A cylindrical tool holder 3 is fitted in the T-slot provided on the slide block. A tool is

fixed in the tool holder by means of a screw 9. A circular washer 7 is provided on the slide block

which forms a bearing surface for the cutting tool.
