Auto Downfeed Surface Grinders


Machine Feature

Precision spindle ultraprecision (P4 level) bearings, to ensure the best quality grinding.
Optical Devic
Down feed can be installed with optical ruler, make more accurate.
Upper & Lower Minimum Feed Amount: 0.001mm; NC System Feature
Can be divided into coarse grinding, fine grinding two-stage process, and with 0-9 times to ensure that no spark grinding precision grinding.

Spindle position can be set at any point zero.

Planning of 0:00 reset function, when the spindle movement, just by pressing the zero reset, you can reset to zero.

Spindle moves up and down to do: 1. Speed 2. feed into Jog 3. Micro 4.MPG electronic handwheel: Feed rate 1μ, 5μ, 10μ.
All the Digital Input, Don’t Need to Calculate, More Easier Operation
Grooving Choose Unilateral or Bilateral Feed.

After the Processing is Completed Selectable: 1.Does not Stop, or Only the Warning Lights Flashing 2.After Milling is Completed, the Table Off the Right Stop + Power Off.
