GTI / GTIN - Tapping Attachment

GTIN ER32 – Tapping Collet Description
Compact tapping collet with tension and compression Short tap chucks for ER collets.
floating mechanism for ER32 collet chucks. Applications
A tapping collet for standard and rigid tapping operations. Axial float/tension/compression type for
GTIN ER32 collet make tap removal and replacement CNC milling machines and lathes with
easy, quick and reliable. Designed for stationary and reversing motors and rigid tapping.
rotating applications. GTIN ER32 collets are economical
and efficient due to the ability to use existing ER32 Features
collet chucks (with various shank sizes and types). • Compensates for machine feed and tap pitch variance
• Floating mechanism compensates for
Applications misalignment between tap and workpiece
The GTIN ER32 tapping collet is designed especially for • Right- and left-hand tapping
CNC mill/turn centers using regular and rigid tapping.
Advantages
Advantages • Practical and efficient tap holding by the ER
• Quick tap change by a front clamping nut spring collet without using jaw drive
• Compact design for minimal clearance • Compact design for minimal clearance applications
between the turret and chuck • Heavy duty design for high torque drive ensures
• Fits every type of stationary and rotating ER32 collet chuck the same accuracy as the tap itself
• Positive tap drive with internal square driver
• Compensates for machine feed and tap pitch
variance, resulting in greater thread accuracy
• Floating mechanism compensates for
misalignment between tap and workpiece
• High accuracy due to tension and
compression mechanism
• Available for all tap shank standards (DIN, ISO, ANSI, JIS)
• Tapping range M1-M16 (#0 to 5/8”)
• Saves setup time by quick tap changing
without removing GTIN from the machine
• Optimal for machines that have limited space
between the turret and workpiece

1 Enter feed rate according to thread pitch (or 1-2 % lower).
Set spindle to starting point with 0.08 clearance.
2 Start spindle forward with right hand rotation
until reaching desired depth.
3 Stop feed and rotation and reverse to starting point.
