Numerical-control precision machining grinding machine

Abstract

The invention relates to the technical field of grinding machines and discloses a numerical-control precision machining grinding machine. The numerical-control precision machining grinding machine comprises a grinding machine body, the top face of the grinding machine body is provided with a workbench, the workbench is internally and fixedly connected with an electromagnetic suction cup in a sleeved manner, the top face of the electromagnetic suction cup is provided with a grinding wheel, the outer side of the grinding wheel is provided with a protection cover in a sleeve connection manner, and the two sides of the bottom of the protection cover are fixedly connected with fixing sleeves. According to the numerical-control precision machining grinding machine, by means of the manner that connecting plates, adjusting plates and shrinking plates are connected and fastened by corresponding fixing bolts and screws, the shrinking plates are made to be close to the outer side of the grindingwheel, the width of a gas passage between the grinding wheel and the protection cover is reduced in disguised form, the airflow moving direction and state at the outer edge part of the grinding wheelare forcibly changed, and then air cushion fluid formed under high-speed rotation of the grinding wheel is destroyed, grinding fluid is made to make full contact with a workpiece for cleaning and cooling, meanwhile, the problem that the grinding fluid is atomized and dispersed around by the air cushion fluid also can be solved, and the working environment is improved and the staff physical healthis maintained.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a grinding machine for numerical control precision machining. Background technique [0002] CNC grinding machine is a machine tool that uses abrasive tools to grind the surface of workpieces through numerical control technology. Most of them use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oil stones and abrasive belts and free abrasives. Some ultra-finishing grinders, CNC surface grinders, etc. [0003] However, there are still some problems in the actual processing of the existing CNC grinding machines that need to be improved. First, during the high-speed rotation of the grinding wheel, the outer edge and the side walls on both sides will drive the air to make a circular motion, forming a strong layer around the grinding wheel. Powerful air flow, also known as air cushion, will form an isolation between the grinding fl...
