In the 1830s, in order to adapt to the hardened processing of parts such as clocks, bicycles, sewing machines, and firearms, Britain, Germany and the United States developed grinder honing machines that use natural abrasive wheels. These grinders were made by adding grinding heads to existing machine tools such as lathes and planers. They were simple in structure, low in rigidity, and prone to vibration during grinding, requiring operators to have a high level of skill to achieve precision. Artifacts.
The Universal Cylindrical Grinding Machine made by Brown-Sharp Company of the United States, exhibited at the Paris Exposition in 1876, was the first machine with the basic characteristics of a modern grinding machine. Its workpiece headstock and tailstock are installed on a reciprocating worktable. The box-shaped bed improves the rigidity of the machine tool and is equipped with internal grinding accessories. In 1883, this company produced a surface grinder with the grinding head mounted on the column and the worktable reciprocating. Around 1900, the development of artificial abrasives and the application of hydraulic transmission greatly promoted the development of grinders. With the development of modern industry, especially the automobile industry, various types of honing machines have come out one after another.
At the beginning of the 20th century, planetary internal grinders, crankshaft grinders, camshaft grinders and piston ring grinders with electromagnetic chucks were developed successively to process cylinder blocks. The automatic measuring device was applied to the grinder in 1908. Around 1920, centerless grinders, double-face grinders, roll grinders, guideway grinders, honing machines and super-finishing machine tools were successively manufactured and used; in the 1950s, high-precision cylindrical grinders for mirror grinding appeared; in the late 1960s High-speed grinders with a grinding wheel speed of 60-80 m/s and large depth of cut, slow-feed grinding surface grinders appeared again; in the 1970s, a honing machine was obtained on the grinder using the digital control and adaptive control technology of the microprocessor Wide range of applications.
