Centerless Grinders CNC Series - alloy bearing type spindle FCL-20 is a product with excellent performance. Grinding accuracy is very important for many industries. The spindle of this series adopts high-quality alloy bearings to ensure stable and high-accuracy operation. At the same time, the one-V-one-flat structure of the lower slide further improves the feeding accuracy of the grinder. The controller adopts CNC numerical control feed, with graphic man-machine interface, which makes the operation more flexible and efficient.

As a professional Centerless Grinding Machines manufacturer, we are committed to providing high-quality products and perfect technical support. We know that grinding accuracy is very important to the needs of customers and the competitiveness of the industry, so we continue to strive to improve our product performance and technical level. When you choose the FCL-20 Centerless Grinder, you can rely on its high-accurate grinding capabilities to deliver excellent results for your machining jobs.


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.


Pressure Switch

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.


Feed Screw

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.


Lubrication system

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.
