GRINDING MACHINES
Yorky Grinder Type 'O'
Yorky Grinder Type 'R'

* One piece bed, 45° slant bed construction ensures maximum stability and convenient chip disposal.
* Alloy steel spindle with opposed taper roller bearings.
* All gears in the headstock are hardened and precisely ground.
* Automatic ranges of spindle speed through pneumatic gear shift.
* Spindle speed ranges are automatically changed by M code.
* Infinitely variable speed are commanded by S code.
* Tool change are commanded by T code.
* Auto lubrication system is equipped for headstock, carriage, and cross-slide.
* Precision tapered roller bearings are equipped on the spindle and the quill.
* The quill is heat treated and precisely ground.
* Internal taper of quill to suit MT#5 dead center or live centre.
* Turcite B anti friction material is applied on cross slide and carriage for reduce friction.
* X and Z axis ballscrews are protected by covers to prevent ingress of swarf / chips and coolant.

* V12 turret.
* Rotating tailstock quill with 160mm diameter.
* Motorized tailstock body and quill movement.
* FANUC 0i-TF series complete with manual guide and thread repair.
* Front chip conveyor.
