Machining Operations 10-1 SG9A Manual

Chapter 10 Spindle to Work:
When the cylinder head is clamped properly on the
table and adjusted, float the workhead to the first
valve guide by pressing spindle float.
At this point, the spindle and workhead should be
level according to the position of the cylinder head.
Most machining operations require the spindle to be
directly centered over the work to be performed.
This is usually accomplished by air floating the
workhead above the area to be machined, then
manually lowering the spindle to the pilot shank with
the spindle adapter sleeve on the down position,
once that you have the toolholder about ½” in to the
pilot shank release the sleeve to the upper position to achieve perfect centering according to the position of the pilot
and lower the toolholder into the pilot manually until reach the proper height or until the carbide tip is a few
thousands from making contact on the valve seat. Do not make contact with the seat surface, the work head should
be floating at all the time for few seconds, do not touch the workhead when is on centering mode.
Special care should be taken in centering the floating Workhead. (keep hands away from flouting Workhead)
Note: when machine the seat, the sleeve should be in upper position. The work head should be in float mode at all
times when is on the centering mode.
NOTE: It is important that the operator of the SG9A read the Control Definitions chapter in this manual
before proceeding any further.
