The Advanced Manufacturing Technology Research Institute (Amtri) is still hopeful that its high speed spindle will get developed to production, despite the fact that it does not work properly and is a year overdue.

Amtri and its consortium members, including spindle, fixturing and tooling manufacturers, as well as end users, expect the three-year Department of Trade and Industry-backed project to make a spindle that runs at various rates and torques and make it to production.

Alan Clayton, Amtri’s project manager said: `There’s a necessity in industry for machinery to move faster on their axes, on faster drives, and at variable speeds.’

The high speed spindle project ran out of money a year ago when the £1m DTI grant expired. The spindle is not finished because of technical difficulties.

The spindle has so far only run at 13,000rpm. The goal is to reach 30,000rpm; engineers expect to reach 22,000rpm by redesigning the spindle.

Amtri and its partners will use its own resources to make the prototype work. It hopes to sign up an outside partner to develop it commercially when the spindle is complete. Amtri’s spindle is a year ahead of a similar project in the US.
