High speed grinding machine

Abstract

The invention discloses a high-speed grinding machine comprising a machine body and a post extending from the rear portion of the machine body upwards. The top of the machine body is provided with concave machining groove, and a moving device capable of moving longitudinally is arranged in the machining groove and is provided with a workbench; the post is provided with two vertical guide rails and a screw which is located between the two vertical guide rails, a vertical sliding table is arranged on the vertical guide rails in a sliding manner, and the top of the post is provided with a vertical driving part and a vertical driving part which are used for driving the screw to rotate; a machining part is arranged on the front of the vertical sliding table, a spindle component is arranged below the machining part, a machining driving unit used for driving a spindle of the spindle component to rotate in a hight speed is arranged above the machining part, and a grinding tool is detachably fixed at the front end of the spindle component. The grinding machine is simple in structure, high in grinding speed, high in machining efficiency, and good in lubricating effect; abnormal heating of a bearing is avoided, and smoothness and accuracy of machining are guaranteed.

Description

technical field [0001] The invention relates to the technical field of grinding machine tools, in particular to a high-speed grinding machine tool with high precision and good lubrication performance. Background technique [0002] Commonly used grinding machine tools can effectively grind the surface of the workpiece. The front end is provided with a spindle supporting the grinding tool to drive the grinding tool to rotate, so that the surface can be ground and processed by grinding discs and other tools. [0003] In the existing machine tools, in order to efficiently process the bearings used in the spindle unit of the machine tool, the speed has been increased. If the discharge performance of the lubricant is deteriorated in the bearing rotating at high speed, there will be too much lubricant, and abnormal heat will be generated due to the generation of stirring heat. In such a case, the temperature of the bearing rises abnormally, which may cause damage to the bearing. ...

AI Technical Summary

Problems solved by technology

In the cage of such a cylindrical roller bearing, the guide gap between the outer peripheral surface of the cage and the inner peripheral surface of the outer ring is narrow, resulting in deterioration of lubricant discharge performance, and a long test run is required.

[0006] Moreover, under high temperature conditions, the neutrality of the bearing becomes worse, which reduces the machining accuracy

[0007] Therefore, the problem to be solved in the prior art is that in the case of too much lubricant, the rolling bearing is prone to abnormal temperature rise, and maintains good centering during high-speed motion
