Fully programmable
C-Axis
rotary axis for
contouring
operations
Can be clamped in

Y-Axis Configuration
2-Axis Wedge Design
• X-Axis
• Used to compensate for clearance
of the moving Y-axis
• Y-Axis
• Programmed as perpendicular
plane to the X-axis.

26. Radial Clearance
Limited clearance for long tools –
especially on the TMM (pictured)
Measure before indexing turret
Use offset toolholders when
possible
27. Axial Clearance
Limited clearance for long tools
Clearance issues on both front and back
side of turret (main & sub-spindle)
31. VDI Turrets
Must indicate holders due to allowable
play in mounting
Some holders have adjustment dials
built-in to the holder
32. VDI Advantages
Quick change-over
More availability of flexible tool
holder options than BMT
Versatility – can be used on
different turret styles (TMM or
MY/MYS)
Typically has higher quality
bearings than BMT
Can be adjusted for increased
accuracy
33. BMT Turrets
No need to indicate
Locating keys present on turret
34. BMT Advantages
More rigid setup
Keyed for quick alignment – but
also has no ability for fine
adjustment
Can be DIY if needed – make
your own
36. Advantages
3-Jaw Chuck No part pull-back when closing
Flexible – wide range of sizes
Can clamp out-of-round or
irregular shaped parts
Disadvantages
Must grease daily
Not as accurate as collets
Difficult to change stock sizes
Serrations can damage part
surface
37. Collet Chuck Advantages
Easy change-over
Chuck diameter is smaller –
providing less interference
Increased accuracy
Low maintenance – no grease
Disadvantages
More expensive
Separate collet needed for each
clamping diameter – requires
storage of many collets
Part can pull-back when closing
