GRINDING APPLICATIONS

 


STRAIGHT GRINDING

Small quantity grinding : auto.
infeed+sparkout timer can obtain good
grinding results. For mass production,
2-steps auto infeed + 2-steps auto
measuring system (optional) for
productivity.


SHOULDER GRINDING

Capable of external and shoulder grinding
in one step. With the work piece supported by two centers this enables shoulder grinding on either side. For special applications, the wheel head can be turned to a certain degree.


LONGITUDINAL GRINDING

Intermittent automatic infeed and hydraulicdriven table provide the workpiece with the most effective longitudinal grinding.

     


END SURFACE GRINDING

Dismantle the cover of the spindle head.
Install a 3-jaw or 4-jaw chuck. Change the position of the pin so as rotate the chuck. Place the pin at 90 degrees for end surface grinding.


TAPER GRINDING

With the work piece held by chuck or two
centers the table and the wheel head can
swivel to accommodate taper grinding.
Adjustments are easy.


INTERNAL GRINDING

Internal grinding is possible with an optional hinge type attachment.
