We can grind parts from .100 to 4.500 inch Diameter by 18 inches long, Infeed, thru feed and profile. Unlike center-type or chucker-type grinding, parts made using a centerless process do not require center holes, drivers or workhead fixtures. Instead, the workpiece is supported on its own outer diameter by a workblade located between a high ...

With both through-feed and profile centerless grinding capabilities, we can take on projects with challenging requirements for surface quality, size, or concentricity. To ensure accuracy, we closely monitor every step of the process, from feed rate to wheel force to rotational speed to dressing method.

Increase traverse or in feed rate to make wheel act softer. Or use a softer grade wheel—consult your grinding wheel manufacturer's representative for specific particulars. Insufficient coolant when grinding tubing or other hollow work such as pistons, etc Increase flow of coolant at point of contact. Grinding pressures too high.

Through-feed grinding is performed by tilting the horizontal axis of the regulating wheel. Thus, centerless grinding can efficiently regulate the feed rate of the workpiece during this operation. The workpiece, or bar, is fed into the grinding wheel and the regulating wheel. There is a continuous motion of bars entering one side and flying out ...

Even with fine feeds, graphite will tend to chip slightly on the exit side. If too heavy a feed rate or dull tools are used, heavy chipping will occur. Grinding. Surface grinding — Standard surface grinders can be used with graphite, but the wheels must be kept sharp. The most common grinding wheel used is a green wheel, composed of 60 grit ...
