The clamping device on the 2M8015 Vertical Center Hole Grinder produced by our company, with the “V”-shaped jaws and finger jaws fixed on the upper part of the left and right sliding plates respectively, is capable of realizing the automatic centering of cylindrical workpieces in a clamping mode. As the machine tool in the machinery industry to promote the scope of application, some rotary parts, although the basic size of the machine tool in the processing range, but its structure is special, such as the journal size difference is large, the positioning journal size is shorter, or journal size difference is large, the positioning journal size is long, but the positioning journal at the top end of the groove or a hole, etc., the jaws can not be clamped, in order to adapt to the needs of these special workpiece clamping in the original automatic centering clamping device structure based on the “V” shaped clamping device and finger-shaped clamps were fixed on the left and right slide plate. In order to meet the needs of these special workpiece clamping, on the basis of the original automatic centering clamping device structure, the design of the jaws mounting guide. In order to realize the up and down movement of the jaws, a screw adjustment mechanism is designed.

In general-purpose grinding machines (surface grinding machines, cylindrical grinding machines, etc.) and bearing inner ring outer groove grinding machines are used in large-diameter, high-rotation grinding wheel grinding, grinding when the outer diameter of the wheel is 150 mm and larger wheels, wheel mass range of 0.2-300 kg need to be balanced on the wheel, wheel imbalance to make the use of its serious consequences, resulting in wheel The imbalance of the grinding wheel has serious consequences during its use, resulting in vibration of the grinding wheel frame and its system, causing ripples in the processed workpiece, reducing the quality of workpiece grinding, increasing the surface roughness of the workpiece, and accelerating the wear of the spindle bearings. Therefore, in order to ensure the quality of the grinding workpiece and prolong the service life of the spindle, it is necessary to carry out balancing of the grinding wheel and the grinding wheel chuck together prior to the grinding process.
