1.      The advantage of the cross-grinding option is that the cross feed speed is infinitely variable yielding a very wide range of cross feed choices.

2.      In criss-cross grinding, the table longitudinal movement and wheel head cross feed movement are synchronized and engaged simultaneously.

3.      This grinding method is invaluable for grinding very thin workpieces efficiently.

ELECTRIC TOUCH CROSS TRAVERSE SETTING SYSTEM-

1.      The advantage of the electronic ‘one-touch’ system is to quickly electronically pre-set the beginning and end surface width of cross grinding to be accomplished. This can significantly improve production time.

2.      Setting the system is simple-

• .Hold power rapid cross feed pushbutton down until the grinding wheel reaches the desired start position.
• .Push the start SB12 pushbutton which will flash an indicator lamp on the command panel.
• .Hold the power rapid opposite crossfeed pushbutton down until the desired finish location of the grinding wheel is achieved.
• .Push the SB12 pushbutton again which will cause the lamp to flash again. This is the desired end of cross feed grinding position and the settings are completed.
  3.      Positioning accuracy is 4mm (0.1”) for PSGS series grinders.
  Positioning accuracy is 5mm (0.2”) for PSGC and PSGO series grinders.
  Positioning accuracy is 10mm (0.2”) for PSGP series grinders.
