Mould industry in zhejiang province has a long history and a more rapid development in recent 10 years, the scale has become the second, the development speed is much higher than the national average, and has many features, development experience is worthy of reference for other parts of the mold industry.

Because after 50 years of efforts, China's machine tool industry has been formed by the relatively complete varieties of category, host, and supporting the formation of complete manufacturing system, and has a technical force of scientific research institutes and a number of key leading enterprise, and technological innovation and new product development capability.

Affordable high speed boring and milling machine top speed of 8000 RPM, bearing adopts universal combination bearings, main shaft adopts IS040 spindle gun barrel type, single nut ball bracket 7 j structure, three axial guideway adopt rolling guide, Y axis adopt with double guide rail support, such a machine tool structure design are the same in the day before yesterday, it should be said also basic can meet the demand of machining of the general. But in the mould processing is Ming series revealed significant spherical cutter mirror processing the problem of insufficient rigidity, machine efficiency can't display, so that lose the advantages in the competition.

Taiwan over the past few years for the spindle of machine tool structure is greatly improved and main shaft adopted two bearing structure and double adjustment after the first four female and strong jaw broach structure, three tutoring rail adopts high rigid sliding guide rail structure, bullying is Y guide adopted four guide rail structure, so that the dynamic rigidity, machine tool spindle rigidity, mobile parts reliability and carrying capacity, etc to increase rapidly.

In such a situation, the author think the domestic machine tool manufacturers goal should be to, make every effort to meet the demand of domestic market, exported to countries in the second development of the world at the same time. If there is a proper positioning, jean valjean plus domestic cheap resources, can still fight for the considerable market share. Double spindle machining center
