FEATURES AND CONSTRUCTION

Both V-ways of the table are precision ground and hand scraped, they are lubricated by hydrostatic lubrication system for smoother movement and longer machine life. The table moves in the longitude axes only while the machines column moves in the cross feed axes. The table is fully supported by the base casting even when at either end position.

All of the major cast iron components such as the base, table, column, wheel head and saddle are honey comb ribbed and are annealed to relieve stress improving the machine performance and life expectancy.

The vertical travel of the wheel head is driven by a precision ground ball screw and A.C Servo Motor with encoder. The slide ways are lubricated by an automatic lube system to insure smooth movements.

Easy setting of the cross travel, for automatic cross feed is on the control panel setting distance and reversal points viz the push buttons on the control panel.

POWERFUL PLC TOUCH SCREEN CONTROL

A precision ballscrew, and A.C. servo motor with encoder, coupled with the PLC touch screen control allows the operator a wide range of grinding programs and control features. Grinding cycles include: Surface, Plunge, and Crisscross modes.

A color touch screen is easy to read and simple to operate. Both rough and fine feed rates can be set on the touch screen. The wheelhead can be jogged up or down with use of two push button switches.
