A prototype oil tool grinder,unveiled at the UK's MACH 2006 machine tool show, is specifically designed for the frequently harsh and demanding tasks of grinding oil tools
As a result the majority of the process becomes automatic, apart from loading and unloading, releasing the operator for other duties.
The machine built and commissioned for major French glass manufacturer.

A second order has also been received from Roshibus - a major Russian glass manufacturer and supplier of organic glass used on the MIG 29 aircraft.
The static and dynamic rigidity of the 'Power Polish' and CNC control provides the ability to grind and polish to much tighter tolerances than was previously possible.
The CNC control coupled with Crawford Swift's unique design delivers load, force and position control via a touch screen PC The PC front end or manual pendant control provides ease of use for the operator and control of all the process variables and gives systems feed back with data storage and retrieval, allowing tractability of every individual component ensuring the highest possible quality.
The technology behind Crawford Swift's new machine features a massive 4000mm diameter cast Iron, epoxy faced vacuum table and precision polishing spindle carrying quick change 1000mm diameter grinding or polishing discs, with through spindle coolant.
The spindle is mounted on a heavy duty oscillating overarm that traverses over the table.
In addition, the table and spindle counter rotate to provide a precisely controlled grinding and polishing action.
Carl Griffiths, of Crawford Swift said of the French order: "We are absolutely delighted that the 'Power Polish' is being used by our international customers".
