Do You Know The History of Grinding Machine?

A machine tool is a machine that processes metal blanks into machine parts. It is a machine that manufactures machines, so it is also called a "working machine" or "tool machine", which is customarily referred to as a machine tool. So what are the machine tools?

There are many methods for processing mechanical parts in modern machinery manufacturing: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc., but all parts with high accuracy requirements and fine surface roughness requirements are generally required Final machining is performed on the machine by cutting. In general machine manufacturing, the processing workload of machine tools accounts for 40% to 60% of the total machine manufacturing workload. Machine tools play a major role in the modernization of the national economy.

The machine tools are mainly classified according to the processing method and the tools used. According to the national machine tool model compilation method, the machine tools are divided into 11 categories: lathes, drilling machines, boring machines, grinding machines, gear processing machines, thread processing machines, milling machines, planing machines, drawing Beds, saws and other machine tools. In each type of machine tool, it is divided into several groups according to process scope, layout type and structural performance, and each group is divided into several series. Here is a brief description of the grinder.

Grinding Machine

Grinding is an ancient technology that has been known to man since ancient times. In the Paleolithic era, grinding stone tools used this technology. In the future, with the use of metal appliances, the development of grinding technology was promoted. However, designing a veritable grinding machine is still a modern thing. Even in the early 19th century, people still ground by rotating the natural grindstone and letting it contact the processing object.

1. The first grinder (1864) In 1864, the United States made the world's first grinder. This was a device for mounting a grinding wheel on the slide tool holder of a lathe and making it automatic. Twelve years later, Brown in the United States invented a universal grinder close to modern grinders.

2. Artificial Grinding Stones- The birth of grinding wheels (1892) The demand for artificial grinding stones also rose. How to develop a grinding stone that is more wear-resistant than natural grinding stone? In 1892, American Acheson successfully produced silicon carbide made of coke and sand. This is an artificial grinding stone now called C abrasive. Success, in this way, the grinding machine has been more widely used.

In the future, due to the further improvement of the bearings and guide rails, the accuracy of the grinding machine is getting higher and higher, and it is developing in a professional direction.

Dedicated to the policy of precision and promotion from stability, the group spares no effort in innovation, improvement, integrity management and insured quality.
