A grinder is a grinding machine that grinds the surface of a workpiece with a lap that is coated with or embedded in an abrasive. It is mainly used for grinding high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, thread surfaces and other profiles in workpieces. The main types of grinders are disc grinders, shaft grinders and various special grinders. The grinder control system uses PLC as the control core, and the text display is the control method of the human-machine dialogue interface. The man-machine dialogue interface can dialogue with people on equipment maintenance, operation, faults and other information; the operation interface is intuitive and convenient, program control, and operation are simple. All-round safety considerations, abnormal operating conditions are ineffective. Real-time monitoring, faults, false alarms, easy maintenance.
Types of
The main types of grinders are disc grinders, shaft grinders and various special grinders.
Disc grinder
Divided into two kinds of single disc and double disc, the most common use of double disc grinder. In a double disc grinder (see Fig. [Double disc grinder]), multiple workpieces are simultaneously placed in a cage located between the upper and lower grinding discs. The cage and the workpiece are moved parallel to each other by an eccentric or planetary mechanism. . The lower grinding disc rotates, and the upper grinding disc parallel thereto may not rotate, or rotate in the opposite direction with the lower grinding disc, and may move up and down to press the workpiece (adjustable pressure). In addition, the upper grinding wheel can also be rotated by an angle with the rocker arm for loading and unloading the workpiece. Double disc grinder is mainly used to process two parallel surfaces, one plane (additional accessories for pressing the workpiece), outer cylindrical surface and spherical surface (using grinding disc with V-groove). When machining the outer cylindrical surface, because the workpiece must slide and roll, the type and arrangement angle of the cage slot must be reasonably selected. The single-disc grinding machine has only one lower grinding plate for grinding the lower plane of the workpiece, so that workpieces with different shapes and sizes can be processed with the same disc, and the grinding accuracy is high. Some mills also have a mechanism that automatically corrects the grinding disk during grinding.
Rotary grinding machine
The rotation of the workpiece or lap (adjustable grinding ring or grinding rod) by the positive and negative rotating spindles is relatively simple, and is used to grind the inner and outer cylindrical surfaces.
Special grinding machine
Depending on the workpiece being ground, there are center hole grinders, steel ball grinders, and gear grinders.
In addition, there is a centerless grinder similar to the principle of centerless grinding for grinding cylindrical workpieces.
Grinding machine features
1. The automatic grinding machine [1] is also a high-speed grinding machine and a precision grinding machine. The use of abrasive cloth belt, electrical appliances using Japan and spring, Fuji, the whole spray, the color of the computer color.
2. The guide rail is a Taiwan linear guide.
3. Squeegee adopts card lock design, which can make the deformed scraping rubber straighten to ensure the grinding quality.
4, this automatic grinding machine, high-speed grinding machine, precision grinding machine can be used for mechanical scraper and manual scraper grinding.
5, special grinding wheel design, grinding cloth with no pressure, no deformation plastic, no corrugated phenomenon, to ensure the accuracy of grinding.
6, grinding degree to match the efficiency of various special printing.
7. The grinding machine is equipped with a dust cleaning device, which can reduce industrial pollution and is conducive to the health of the staff and the maintenance of the equipment.
8, automatic grinding machine, high-speed grinding machine, precision grinding machine is easy to operate, without professional skills to operate.
