Problems solved by technology

[0012] According to the data of PJM320B type surface fine grinding machine, its linear speed is too low when processing high hardness composite ceramics and alloy tantalum and niobium materials. The removal of the abrasive surface is difficult to control, and the grinding tools on the grinding disc must be repaired frequently

Abstract

The invention relates to a surface grinder spindle device and a planetary grinding disc device. The spindle device comprises an inner spindle and an outer spindle. The grinding disc device comprises a revolving disc, a solar grinding disc and a planetary grinding disc. The revolving disc moves at low speed while the solar grinding disc and the planetary grinding disc move at high speed, the inner and outer spindles and the planetary grinding disc are associated with an upper gear case and a lower gear case, and the inner and outer spindles can be driven by one or two variable frequency speed-adjusting motors. The device has the advantage that: by means of the modification of traditional technology, namely one large grinding disc is changed into a plurality of small grinding discs, centrifugal forces of the grinding discs is reduced, overall linear speed of grinding heads is enhanced, surface shape of grinding tools can be repaired effectively by utilizing workpieces to realize constant removal, and repair times of grinding tools is reduced. Therefore, the effect of increasing yield and efficiency and saving energy is obtained, and simultaneously, an outer planetary grinding disc can be further arranged on the grinder according to the requirement of processed products.

Description

1. Technical field [0001] The invention relates to advanced manufacturing high-speed grinding technology. 2. Background technology [0002] The current track-type surface grinder mainly grinds the periphery of the emery wheel, which has a small contact surface with the workpiece when grinding a large plane. Refer to face grinder, horizontal, vertical double-sided grinder spindle and disc device. The workpiece is ground with the abrasive tool fixed on the end face. Although the contact surface with the workpiece to be processed is enlarged, they have a fatal weakness that the larger the grinding disc, the removal amount of the abrasive tool is unbalanced during grinding. The phenomenon becomes more serious. The larger the diameter of the grinding disc does not mean the higher the production capacity per unit area. The larger the diameter of the grinding disc, the higher the manufacturing cost of the grinding machine, and the closer the grinding disc is to the inside, the l...
