Adjusting the Square Carbide Inserts
:
The micrometer should be used.
Set the Digital micrometer (BM) according to the
valve seat insert diameter and the required
interference.
Slide the tool holder without the pilot on the
micrometer.
With the setting screw, adjust the square tip holder
offset.
IMPORTANT:
When 90 degreed bits (RCA512) or the Triangle bits are fitted, check that their reference
faces are perfectly clean.
The accuracy of the seat angles depends on this.
While rotating the assembly tool holder/carbide tip holder, the carbide bit’s cutting edge should just touch
the micrometer spindle.
Once in contact with the micrometer spindle, the carbide tip should not be moved at all. If this is not
observed, the cutting edge may be damaged and the resulting surface quality, when machining, will be
deteriorated.
Tapping Operations:
Place the Jacobs chuck or Collet Holder in the spindle as explained previously. Install tap in the chuck,
and tighten.
Center over the hole to be tapped
Set spindle RPM at approximately 50 RPM and Feed Rate at .00010
Choose a spindle speed sufficient for the tap (approximately 50 RPM), and allow the tap to feed the
spindle as it threads the hole.
When the proper depth is achieved, press to reverse the spindle rotation and left spindle return the tap off
the hole.
