What Are The Characteristics Of The Centerless Grinder And The Ordinary Grinder?

Apr 22, 2017

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, The rotation of the workpiece, and control the feed speed of the workpiece, as the workpiece bracket is in the grinding support the workpiece, these three parts can have several methods, but stop grinding, the same principle.

The following are the same as the "

The performance of the centerless grinder has the following characteristics compared with the ordinary grinder:

The following are the same as the "

1, continuous processing, without retracting, clamping parts and other replication time is short, high productivity.

The following are the same as the "

2, the bracket and guide wheel positioning mechanism than the ordinary cylindrical grinder top, the center frame mechanism of good rigidity, the amount of cutting can be large, and is conducive to the processing of slender shaft parts, easy to achieve high-speed grinding and strong grinding.

The following are the same as the "

3, the centerless grinding machine workpiece by the outer circle in the positioning mechanism on the positioning, the amount of grinding is the balance of the workpiece diameter, so the grinding wheel wear, feed mechanism compensation and cutting mechanism of repeated positioning accuracy error on the dimensional accuracy of parts diameter . Only half of the ordinary cylindrical grinder, do not need to hit the center hole, and easy to achieve on, cutting automation.

The following are the same as the "

4, wide grinding wheel centerless grinder through the type of institutions, can be used to increase the processing of each margin, in the cut into the mill when the complex surface can be grinding or grinding wheel grinding, high productivity, wide range of applications.

The following are the same as the "

5, the centerless grinding machine does not guarantee grinding surface and non-grinding surface relative position accuracy (coaxial degree, vertical degree, etc.) of the body, grinding the circumferential surface of the intermittent roundness is poor.

The following are the same as the "

6, the grinding surface is easy to produce odd degree of roundness, such as the larger will often result in measurement size is less than the maximum physical size of the illusion, and affect the assembly quality and performance.

The following are the same as the "

7, machine adjustment more complex, time-consuming, each change the diameter of the workpiece to be adjusted to adjust the height of the bracket, and the distance and the relevant process parameters. So the adjustment technology is more difficult, not suitable for small batch and single production.
