With a highly experienced design and manufacturing background in centerless grinders, PALMARY present a new series of CNC centerless grinder. It is designed and engineered to offer the operational performance you've come to expect.
Equipped with an advanced CNC control, featuring operator-friendly operation with maximum control convenience. When you require a machine that will greatly upgrade production efficiency and create more profits, PALMARY's new CNC centerless grinder will fully meet your requirements.
Rigid machine structure
The machine structure is manufactured from high quality Meehanite cast iron, heat treated and stress relieved before machining. Slideways are high frequency hardened and precision ground. Maximum material stability for deformation-free and outstanding wear resistance.
When starting the GW and RW spindle, this pressure switch allows starting only when oil enters into bearings thereby providing safety protection for the spindle bearings.
The feed screw is manufactured from alloy steel. It's also normailzed, high frequency harden and precision ground in order to have high feeding accuracy and excellent wear resistance.
The automatic lubricator provides lubrication to the GW spindle. Also all slideways are lubricated by a centerlized lubrication system, ensuring proper lubrication and feeding accuracy.
