| Machine Features: |
 |
Digital feeds and stock removal needs no calculating.
|
"Dialogue" data input system:
Diagram on main panel combines with highlighted step by step instructions on display panel.
|
Coarse and fine feed process combines with spark out process (max. 9 passes) to ensure high precision and high efficiency grinding.
|
Position of vertical axis is displayed at all the times to monitor the wheel spindle. |
Zero set and zero return are also available for easy handing.

1.Rapid movement:230mm/min
2.Semi-rapid movement:230mm/min
3.Detault down feed (Set-up by F value)
4.0.001mm down feed.
5.Manual movement
6.Full automatic |
|
| Does not need to be preset again, even if vertical head is moved from original position or modified from original preset feed amount. |
| There are 3 selections for vertical head elevation: |
|
1.No elevating on Vertical head
2.Elevating to "Zero point"
3. Elevating over "Zero point" to "a" (must be input) |
| Press “Zero Return”, vertical head rapidly descends to "Zero Point" from “a”. Next, press “Auto Cycle” to proceed – safe and fast. |
Transverse and plunge automatic cycles are available. |
| 2 selections of feeding for plunge mode. |
|
1.Left side feeding.
2.Both side feeding. |
End mode selections: |
|
1. Machine non-stop, Buzzer actuated.
2. Machine non-stop, Flash alarm actuated.
3. Work table stops at right side and machine switches off.
