TAPS USER GUIDE

GTI / GTIN - Tapping Attachment Description:
Short tap chucks for ER collets.
Operation
For through- and blind-hole tapping: Application:

1 Enter feed rate according to thread pitch (or 1-2 % lower). Axial float/tension/compression type for
Set spindle to starting point with 0.08 mm clearance. CNC milling machines and lathes with
1 reversing motors and rigid tapping.

Features:
• Compensates for machine feed and tap pitch variance
• Floating mechanism compensates for

misalignment between tap and workpiece
• Right- and left-hand tapping

Advantages:
• Practical and efficient tap holding by the ER

spring collet without using jaw drive
• Compact design for minimal clearance applications
• Heavy duty design for high torque drive ensures

the same accuracy as the tap itself

2 Start spindle forward with right hand
rotation until reaching desired depth.
