Principle Of Centerless Grinding Machine
The centerless grinding machine is a kind of grinding machine which does not need to use the axis positioning of the workpiece to grind. It is mainly composed of grinding wheel, adjusting wheel and workpiece bracket. The grinding wheel is actually grinding work, Control the rotation of the workpiece and control the feed speed of the workpiece. As for the workpiece holder, it supports the workpiece when grinding. The three parts can have several methods, but the same is done except for the stop grinding.Centerless Grinding Machine
A centerless shortened centerless grinder, which is particularly suitable for use in a small installation space and is able to meet the simplicity and space saving requirements of various production lines. Since the grinding wheel dressing unit is disposed at an obliquely downward position above the grinding wheel, it is not necessary to maintain a space for the grinding wheel dressing unit on the side of the grinding wheel, which is most closely related to the transverse dimension of the conventional centerless grinder. Thus, the size of the centerless grinder can be greatly reduced and the grinder can be installed in a small installation space to meet the simplicity and space saving requirements of the various production lines.
Application of the centerless grinding method of grinding the workpiece surface of the grinding machine, usually refers to the centerless grinder. In the centerless grinder, the workpiece without the center of the center and support, but between the wheel and guide wheel, supported by the pallet and guide wheel. The grinding wheel is usually mounted on the end of the spindle, the width of more than 250 mm wheel is installed in the middle of the spindle, the maximum width of up to 900 mm wheel. The grinding wheel rotates at high speed, and the guide wheel rotates in the same direction with the slow speed, which drives the workpiece to rotate for the circumferential feed. Through the grinding, by adjusting the guide wheel axis of the small tilt angle to achieve axial feed, suitable for grinding elongated cylindrical workpiece, no center hole of the short axis and sets of parts and so on.Centerless Grinding Machine
When the grinding is carried out, the radial feed is achieved by the movement of the guide wheel frame or the wheel frame, which is suitable for grinding the workpiece with the shoulder or boss, and the workpiece of the cone, sphere or other thread. The productivity of the centerless grinder is high, and it is easy to realize automation after loading and unloading. It is mostly used for mass production and can be operated by very skilled workers. Centerless grinding machine grinding accuracy is generally: roundness 2 microns, dimensional accuracy of 4 microns, high-precision centerless grinding machine can reach 0.5 microns and 2 microns. In addition, there are no heart round grinder and centerless thread grinder.Centerless Grinding Machine
