Solder the technical development in machine tool industry is as the machine tool the product solders structural application develops and development rises. The dominant product of industry of Chinese machine tool basically has machine of product of metallic cutting machine tool, v product, cast product of product of machine tool of mechanical product, carpentry, tool, grind provide and product of machine tool accessory. Among them, metallic cutting machine tool, forging press fetterses and casting mechanical product is machine tool industry solder the main field of technical application. The technical standard that develops from machine tool product looks solder the technology is divided roughly in the development of machine tool industry for 3 phase.

1.1 solder the technology regards auxiliary technology measure as level

This phase from 20 centuries 50 time arrive at the beginning of 70 time. This phase develops a field in machine tool product basically is to be modelled on phase of product of foreign machine tool. Metallic cutting machine tool is modelled on to have 1 Д successfully at that time 63 model lathe, 2A125 vertical drilling machine, 6H82 all-purpose milling machine, 1617 model center lathe and 262 model horizontal boring machine 150 kinds, occupy about master gross of machine tool breed at that time 204 kinds 70 ％ ; V machinery basically is modelled on developed compressor opening type, 315 tons shut type sheet to nod 300 tons of hammer of compressor, air, the following double plate to grind below compressor, cut machine, 4 column all-purpose hydraulic press and the demand such as machine rolling silk and automatic forging press are bigger.

The structure of product of this phase machine tool is basically entirely cast semifinished product structure, so of this phase solder the technology is to serve as measure of a kind of auxiliary technology to be product service only, soldering key is the blemish solder that casts structural member fills and a few diminutive such as case of case of the gasoline tank of the product, report are not main part. Solder basically the method is manual arc welding, or oxygen acetylene gas welding, rely on him worker to master, without solder normally professional technology personnel and technology measure, did not solder technically workshop. The company with individual bigger dimensions, solder to assemble a workshop to close together with other foundry or product, manufacturing area is finite.

1.2 solder initial application phase of the technology

This phase, from 20 centuries 70 time arrive at the beginning of 80 time, to solder initial application phase of the technology. Product of this phase machine tool on the foundation that in 20 centuries 50 time are modelled on, began the proper motion research of machine tool of high accuracy nicety and development. In respect of metallic cutting machine tool, only 20 centuries 70 time provided 7664 machine tools that have higher level to plant of the 2nd car in succession, satisfied the 98 ％ above that plant of the 2nd car requires machine tool equipment at that time; In respect of forging press instrument, to equip plant of the 2nd car, development considered to make machinery of 115 kinds of 510 general and special v and partial product line. In the meantime, each major chooses this level surely factory accumulative total mastered breed of forging press instrument oneself have 257 kinds.
