Product description

Parameters

1. Product use, scope of application and characteristics

This machine is mainly used for single-sided polishing of sapphire flake materials and single-sided high-precision and high-efficiency polishing of parallel planes of other hard and brittle materials.

The machine adopts touch interface and PLC control. Provide users with an open graphical control interface to give full play to the performance of the mechanical hardware; the main drive of the machine has the characteristics of short transmission chain, stability and reliability; the four upper throwing heads actively rotate, and the pressure control adopts the electric proportional valve to set arbitrarily, and each Each head can be controlled individually; the upper and lower throwing trays are forced to cool by circulating cooling water, and the temperature is controlled accurately.

2. Equipment transmission structure and layout

Ø The main shaft system is located below the equipment. The motor drives the worm gearbox through a narrow V-belt. The gearbox is directly connected to the shaft to ensure its running accuracy. The bottom plate is positioned and supported by cross roller bearings, and the running rigidity and accuracy have been obtained. Good protection, the lower part of the bottom plate shaft is equipped with a rotary joint, which is used to pass cooling water into the throwing plate;

Ø The upper polishing system is located in the upper part of the equipment, the lifting and pressurization of the upper polishing head is realized by the air cylinder, the upper plate is provided with a cooling water channel for cooling the upper polishing head, and the rotation of the upper polishing head is directly driven by a geared motor through a gear;

Ø There is a middle guide wheel device that can be raised and lowered in the middle of the lower throwing plate, and four outer guide wheel devices are arranged at the edge of the liquid receiving basin, and the two can cooperate to realize the automatic positioning of the workpiece plate;

Ø There is a main operation panel on the front of the upper beam of the equipment, which can perform parameter setting, operation monitoring and other functions. There are two small control panels on each side of the beam for the lifting operation of the upper throwing head;

Ø A liquid circuit device is installed on the rear box of the equipment, with passages for cooling water, polishing liquid, and cleaning water for the upper and lower disks;

Ø Front uprights are installed on both sides of the front box and crossbeam of the equipment for auxiliary support of the crossbeam, and the height of the uprights is adjusted slightly;

Ø There are two oil filling ports on the right side of the box, which are used for lubricating the two sets of bearings of the main shaft;

Ø An infrared temperature measuring device is installed on the beam to monitor the surface temperature of the throwing plate;

Ø A slidable protective cover is provided on the outside of the lower throwing plate to prevent the splashing of working fluid and reduce the overflow of harmful gases;
