Lathe used for processing hard contact lenses

Abstract

The invention discloses a lathe used for processing hard contact lenses, and the lathe belongs to the range of optical workpiece processing equipment. The lathe comprises a sharp knife tool device fixed to the mounting surface of a granite platform, a general knife tool device and a workpiece shaft device with a transverse sliding block device, wherein a touch control screen and a front control table are supported in front of the granite platform; an electric control machine cabinet is placed on the rear wall of a machine body; an air processing device comprising a cooling and drying machine and a pressure regulation device is mounted on one side surface of the machine body; and the granite platform is fixed to a machine frame comprising an inner filling shock absorption mixture and a steel structure, so that the machine body with high rigidity, shock absorption property, frequency modulation damping property and vibration isolation property is formed. According to the lathe, high-precision and high-efficiency processing of the hard contact lenses with processing demands of different surface designs, in particular a free-form surface design is achieved and a guarantee is provided for high-precision and high-efficiency turning a free-form surface.

Description

technical field [0001] The invention belongs to the field of optical workpiece processing equipment, in particular to a lathe used for processing hard contact lenses. Background technique [0002] With the development of science and technology, the demand for various machine tool equipment is increasing, and the precision requirements for machine tool equipment are getting higher and higher. Relying on traditional manual or semi-automatic operation methods can no longer meet the needs of the development of science and technology today. In the process of precision machining of machine tools such as turning, milling, and grinding, the stability of the spindle rotation and the degree of wear of the spindle determine the workpiece. The machining accuracy of ordinary machine tool equipment mainly depends on the bearing mechanical support of the main shaft, and the mechanical friction and wear are quite serious. With the increase of processing time, the stability of the main shaft...

Problems solved by technology

Relying on traditional manual or semi-automatic operation methods can no longer meet the needs of the development of science and technology today. In the process of precision machining of machine tools such as turning, milling, and grinding, the stability of the spindle rotation and the degree of wear of the spindle determine the workpiece. The machining accuracy of ordinary machine tool equipment mainly depends on the mechanical support of bearings, and the mechanical friction and wear are quite serious. With the increase of processing time, the stability of the spindle rotation becomes worse, and the machining accuracy of the workpiece is difficult to meet the processing requirements.
