168 Stop-Block Mounting Example

CHECK SUITABILITY OF THE MACHINE TOOL SPINDLE TO MOUNT

A STOP BLOCK.

If stop block is already mounted on the machine tool. H
1. Check the bushing diameter in the stop block
(18mm or 28mm)

2. Calculate the “A” dimension based on the shank choices in Pin detail
the chart. Page 54
Note “B” is calculated from Spindle Gage Line

= =
If no stop block is mounted on the machine spindle. X S
1. The standard positioning pin is OK and it will be necessary Gauge Line 1
to make a spacer if dimension X is larger than the values B *A
indicated in table 1.
2. The positioning pin must be shortened if dimension X is
(Incl.) between values indicated in table 1 (Max shortening
8mm with angle heads type 1 & 2, Max 6,5mm with angle
heads type 3).
Pin
3. It will be necessary for a special positioning pin if *A - 35mm Type1-2
- 37mm Type 3
dimension X is less than the values indicated in table 1.
