With the development of high-precision, high hardness increase in the number of mechanical parts, and precision casting and precision forging technology, performance, varieties and production grinders are constantly improving and growing. (1) Cylindrical Grinder: Grinding is mainly used for cylindrical and conical outer surface. (2) Internal Grinder: mainly used for grinding machine grinding of cylindrical and conical inner surface. In addition, there are both internal and external circular grinding grinder. (3) Coordinate grinder: internal grinder with precision coordinate positioning device. (4) Grinder: mainly used for clamping workpieces using mood, generally supported between the guide pulley and bracket rotation of the workpiece by the guide wheel drive, is mainly used for grinding cylindrical surface grinding machines. For example, the shaft support bearing and so on. (5) Surface Grinder: mainly used Grinding workpiece plane. a. cranked grinder suitable for smaller size and higher precision workpiece, the workpiece can be processed including arc shaped, flat, slots and the like. b. Shuimo suitable for processing large workpiece machining accuracy is not high, hand-cranked grinder distinguished. (6) Belt Grinder: fast moving belt is mainly used for grinding the grinder. (7) grinding machine: mainly used for grinding the workpiece surface within a cylindrical outer surface grinder or. (8) Multi Grinder: mainly used for grinding cylindrical, conical inner and outer surface or plane, and can be used with a variety of moving equipment and accessories grinder grinding workpiece. (9) special grinder: mainly engaged in certain parts of the special grinding machine. Their processing objects can be divided into: spline shaft grinders, crankshaft grinding machines, cam grinding machines, gear grinding, thread grinding machines, grinders and other curves. Hengda NC Machine Tool Co., the best partner by your side - grinding machine manufacturers, manufacturers of CNC grinding machines, CNC vertical grinding machine, surface grinder manufacturers, small grinder price, the price of second-hand grinder, grinder manufacturers. In the eighteenth century, 30 years, in order to adapt the processing watches, bicycles, sewing machines and other parts of firearms after hardening, the UK, Germany and the United States were developed using natural abrasive wheel grinder. These grinders are readily available at the time of the machine, such as lathes, planers and other top installation grinding restructuring, which structure is simple and 7130 surface grinder, the stiffness is low, easy to produce vibration grinding operations require workers to have a high skill grind precision workpieces. 1876 ??exhibited at the Paris Exposition of the American Brown - universal cylindrical grinder manufactured by Sharp, is the first modern basic characteristics of the mechanical grinder. It workpiece headstock and tailstock mounted reciprocating table, box-shaped bed increases the stiffness of the machine, and with internal grinding attachment. In 1883, the company made grinder mounted on the column, table for reciprocating surface grinder. After 1900, the development and application of artificial abrasive hydraulic transmission, the development of grinders have a great role in promoting. With the development of modern industry, particularly the automotive industry, a variety of different types of grinders have been published. Such as the early 20th century, has developed a cylinder block machining inner planets grinder, crankshaft grinder, camshaft grinder and grinder with magnetic chuck piston rings and so on. Automatic measuring device in 1908 began to apply to the grinder. To 1920, the centerless grinder, double-end grinders, roll grinders, rail grinding, honing and super finishing machines, etc. have been made to use; the 1950s appeared to make mirror grinding precision cylindrical grinder; 60s appeared at the end of wheel speed of 60 ~ 80 m / sec high-speed grinder and large depth of cut, creep feed grinding surface grinding machine; the 1970s, the use of digital microprocessor control and adaptive control techniques in the grinder has been widely applications.
