s:Dedicated equipment of high-speed holemaking with multispindle can create multiple holes in a single pass in high-speed holemaking such as drilling ,tapping, the milling of shapes and deep holes, shortening production cycles, increasing production rates and reducing cost.

Development of high velocity compaction technology in powder metallurgy

This paper gives a brief introduction on the characteristics and status of high velocity compaction .

Hydropulsor AB,Sweden,has solved the facility problem that restricted the industrial application of high velocity compaction(HVC) technique after it manufactured and sold its unique hydraulic impactor,which will certainly speed up the development of the HVC technique greatly.

The main technological pacckages available for high speed control of hot strip mills are described.
