Operating instructions GS

Specifications

The tapping spindle type GS has an adjustable ball-bearing, axial movement (floating) which eliminates the machine spindle axial force. This enables the use of taps with different pitch in multi-spindle machines. A hard collaring pressure makes the tap start to cut directly when feeding into the material.

 

A major advantage of the GS is that the floating can be adjusted forward or backward in order to achieve the best results.

Putting into operation

The tapping chuck has an internal taper for assembling on to an arbor shaft, or directly to the machine spindle. The internal taper is prepared with two holes for fixing it against the arbor. We always recommend fixation to the arbor taper by dowelling. 

When mounting into a machine, please follow the 4 steps of the instructions.

Adjusting the floating

The tapping spindle can be adjusted to allow full floating backward, forward or in both directions. Use an Alen key for adjustment. Clockwise turning extends the forward floating and counterclockwise extends the backwards floating.

  1. Before assembling on a taper, the floating movement shall be compressed to protect the internal components from damage. Screw clockwise to the bottom.

  2. Clean the internal taper and the machine taper properly before exampling of the tapping spindle.

  3. Assemble with a hard push. Do NOT use a hammer other violent treatment.

  4. Re-tighten the floating screw counterclockwise and fix the taper by dowelling. Now the floating can be adjusted for the best performance.

Adjusting the floating

The tapping spindle can be adjusted to allow full floating backward, forward or in both directions. Use an Alen key for adjustment. Clockwise turning extends the forward floating and counterclockwise extends the backwards floating.

The spindles total floating is:

GS-8 25 mm

GS-12 25 mm

GS-24 40 mm
