Standard Centerless Ginding Machine
The Standard Centerless Ginding Machine are driven mainly manual or hydraulic. The stadard smallest ground size is 1 mm. Equipped with special thrufeed grinding device, we can grind the size to 0.2mm. we are confidential with our precision straightness and roundness below 0.001mm. The Regulating wheel driven power is through servo moto combined with reducer. It is easy to adjsut the speed of thrufeeding to match with your automation.
According to the methods of feed, centerless grinding can be divided into three types:
- Through Feed Centerless Grinding
- Infeed Centerless Grinding- to grind one step or above.
- End Feed Centerless Grinding – it used for taper or the grinding length more than the wheel’s.
- Through feed Centerless grinding :
Equipped the long bar grinding device, the grinding length can achieve 3 meter.
In addition, we can offer standard throufeeding automation (belt type) is gernally used in the area, diameter from 3-25mmL and the length 50-900 mm, the basical pricipal is the length should be bigger than the diameter.
Vibaration hooper: the diameter from 3mm-12mm, the length 5mm-110mm.
- Infeed Centerless grinding :
The critical concept that G.W line, R.W line and blade line should be in paralle. under the G.W width, the machine can achieve the precision cylindricity below 0.002mm; roundness below 0.001mm. When it comes to profile grinding, you can discuss with our sales engineer to make the template and blade.
The general one step grinding, we can upgrade to high CP value NC1 automaiton. it can save engineer energy and increase the stability. if your workipece is more complicated and not easy to load, the advacing NC machine is recommended.
