Manual grinder surface grinder is a kind of surface grinder with the smallest volume, simple structure and function and low price. It is suitable for the grinding of small and medium-sized molds, electronic components and various small workpieces. Manual flat grinding is a machine tool product with large quantity and wide range. It has a large market capacity. It is suitable for small factories, family workshops and even leisure. There are two types: horizontal and vertical, but the most important is horizontal shaft rectangular table type flat grinding.

The development of manual flat grinding has a long history, which can be traced back to more than 100 years ago. The American & manufacturing company, established in 1833, is the oldest machine tool manufacturer in the world. The company began to manufacture flat grinding machines in 1868. It initially produced manual flat grinding, and then produced hydraulic flat grinding. Automatic flat grinding is developed on the basis of manual flat grinding. The reason why manual flat grinding has lasted for more than 100 years is that it still has strong vitality even in the rapid development of NC flat grinding. This is determined by its small, simple, practical and reliable characteristics. It is certain that manual flat grinding still has a considerable market share for a long time in the future. Situation of domestic manual flat grinding skid manual flat grinding developed relatively late in China. There was only a small amount of production in the 1970s and developed rapidly after the 1980s. At present, the production of manual flat grinding has accounted for one third of the total production of flat grinding in China.

Hangzhou machine Maple began in the first phase of 1998. As early as 1953, Shanghai machine tool factory introduced the Soviet Union 373372375 flat mill to trial produce vertical shaft, horizontal shaft rectangular table and vertical shaft circular table flat mill. Therefore, the development of flat mill in China has taken a different road, with rolling flat mill first. After that, there is manual flat grinding, which is different from the extensive application of manual flat grinding in western industrial countries, and then develop hydraulic flat grinding on the basis of manual flat grinding. There is little understanding of manual flat grinding in China, and there are misunderstandings. It is considered that manual flat grinding cannot be popularized in China. At the same time, under the condition of planned economy, the division of labor in machine tool production is very clear, and manual flat grinding is included in the scope of instrument machine tools. All these restrict the development of manual flat grinding. In this way, for a long time, only Dafeng County Machinery General Factory in Jiangsu Province produced manual flat mill m618, which is also only for export, but the quantity is not comparable with similar products in Japan and Taiwan. Until 1980, Hangzhou machine tool factory designed and manufactured a 150 manual flat grinding machine. In the following ten years, m618 and hz150 manual flat grinding have become one of the few machine tool varieties that can be exported in batch in China, with a total export of nearly 2000 sets, making a great contribution to earning foreign exchange through export. The export areas include the United States, Japan, Europe, Southeast Asia, Australia, Hong Kong and Macao.

With the development of the round market, manual flat grinding has gradually become a hot product. In recent years, township enterprises and individual and private industrial and commercial owners have become the main buyers of machine tools. Manual flat grinding has been widely used in electronics and other industries. For example, there are three enterprises in Guangdong and Shenzhen, each with more than 50 manual flat grinding machines. Some combine manual flat grinding into a production line for processing magnetic heads. Manual flat grinding has become the key equipment of these enterprises, and the market has driven the production. For more than ten years, the development speed of manual flat grinding is quite fast. Enterprises inside and outside the flat grinding industry have developed this kind of variety one after another, mainly through export. The national annual output has grown from more than 100 units in the 1970s to 1500 units at present, and there are more than 10 production plants.
