Grinding machines can process harder materials such as hardened steel and hard alloys; they can also process brittle materials such as glass and granite. The grinding machine can perform grinding with high precision and surface roughness, as well as high-efficiency grinding, such as strong grinding. With the increase in the number of high-precision, high-hardness mechanical parts, as well as the development of precision casting and precision forging processes, the performance, variety and output of grinding machines are constantly increasing and increasing. Tool Grinding Machines are grinding machines for tool making and tool sharpening. They are universal tool grinders, bit grinders, broaching grinders, tool curve grinders, etc., and are used in tool shops in tool manufacturers and machine shops.

Most grinders are ground using high-speed rotating grinding wheels. A few are processed with other abrasives such as oilstone, abrasive belts and free abrasives, such as honing machines, superfinishing machines, belt grinders, grinders and polishing. Machine and so on.

In the 1830s, in order to adapt to the hardening of parts such as watches, bicycles, sewing machines and firearms, the United Kingdom, Germany and the United States developed grinding machines using natural abrasive wheels. These grinders were modified from the existing machine tools such as lathes and planers. They are simple in structure, low in rigidity, and easy to generate vibration during grinding. The artifacts.
The universal cylindrical grinding machine manufactured by Brown-Sharp Company of the United States exhibited at the Paris Exposition in 1876 was the first machine to have the basic characteristics of a modern grinding machine. Its workpiece headstock and tailstock are mounted on a reciprocating workbench that increases machine rigidity and has an internal grinding attachment. In 1883, the company made a surface grinder with a grinding head mounted on a column and a reciprocating table.
Around 1900, the development of artificial abrasives and the application of hydraulic transmissions have greatly promoted the development of grinding machines. With the development of modern industry, especially the automobile industry, various types of grinding machines have been introduced. For example, at the beginning of the 20th century, planetary inner grinding machines, crankshaft grinding machines, camshaft grinding machines and piston ring grinding machines with electromagnetic chucks were developed.
The automatic measuring device was applied to the grinding machine in 1908. Before and after 1920, centerless grinders, double-face grinders, roll grinders, guide grinders, honing machines and superfinishing machines were used one after another; in the 1950s, high-precision cylindrical grinders for mirror grinding were introduced; At the end of the year, there were high-speed grinders with a line speed of 60-80 m/s and large depth-cutting and slow-feed grinding surface grinders. In the 1970s, digital control and adaptive control technologies using microprocessors were widely used on grinding machines. Applications. 
Precision grinding machine for mirror grinding
Grinding machines are the most widely used types of metal cutting machine tools. The main types are cylindrical grinding machines, internal grinding machines, surface grinding machines, centerless grinding machines and tool grinding machines.
Cylindrical grinding machines are the most widely used grinding machines for machining a variety of cylindrical and conical outer surfaces and shoulder end faces. The universal cylindrical grinding machine also has an internal grinding attachment that grinds the inner bore and the inner and outer taper surfaces with a large taper. However, cylindrical grinding machines are less automated and are only suitable for small and medium-sized single-piece production and repair work.
The grinding wheel spindle of the internal grinding machine has a high rotational speed and can grind the cylindrical and conical inner bore surface. Ordinary internal grinding machines are only suitable for single and small batch production. In addition to the automatic work cycle, the automatic and semi-automatic internal grinding machines can also be automatically measured during machining, mostly for high-volume production.
The workpiece of a surface grinder is generally clamped on a workbench, or fixed to an electromagnetic table by electromagnetic attraction, and then grinds the surface of the workpiece with the periphery or end surface of the grinding wheel; the centerless grinding machine usually refers to a centerless cylindrical grinding machine, that is, the workpiece is not used. The top or chuck is centered and supported, and the workpiece is ground by the outer circular surface as the positioning surface. The workpiece is located between the grinding wheel and the guide wheel and supported by the pallet. The grinding machine has high production efficiency, is easy to realize automation, and is multi-purpose. In mass production.

The belt grinding machine is a fast moving abrasive belt as the grinding tool. The workpiece is supported by the conveyor belt. The efficiency is several times higher than other grinding machines. The power consumption is only a fraction of that of other grinding machines. It is mainly used for processing large-sized plates and heat-resistant. Difficult to machine materials and mass production of flat parts.
Specialized grinding machines are grinding machines that specialize in the grinding of certain types of parts such as crankshafts, camshafts, splined shafts, guides, blades, bearing raceways and gears and threads. In addition to the above categories, there are many types of honing machines, grinding machines, coordinate grinding machines and billet grinders.
