SPECIFICATIONS：

CONTROL PANEL
	Vertical feed powered by double motors High efficiency AC motor for rapid up / down. Stepping motor for micro downfeed positioning and slow up / down. Quick digit output feedback by encoder.
	Display for position of axis Y to show the present position of spindle. The digit display is for setting start point, rough grinding volume, start point for finish grinding(finish rginding volume), downfeed volume for finish grinding, target point, rise up point, intermittent spark-out, and spark-out.
	Cross transverse travel powered by DC servo motor. Available for step feed and continuous infeed grinding. The speed for dressing wheel is adjustable on the panel.

General Features：

1.HIGH PRECISION CARTRIDGE WHEEL SPINDLE:

Spindle supported by two precision angular ball bearings & one NN TYPE roller bearing and driven by V3 class motor that allow heavy leaded and high accurate grinding performance.

2.HIGH RIGID CASTING CONSTRUCTION:

The saddle rests on precision hand-scraped double V ways, and the table rests on precision hand-scraped V and flat ways which coated with "TURCITE-B". These guide ways are equipped with auto lubrication to resist wear of guide ways, plus lasting accuracy and damping.

3 AUTO LUBE SYSTEM:

Automatic lubrication system is applied as standard to ensure sufficient lubrication at lead-screws and guide-ways for more longevity.
