MACH 2000: GRINDING

Grinding, honing, lapping, other abrasive machining processes and accessories

600 Centre: Stand 5222

The launch of the Okamoto 65DVX Surface Grinder is the highlight from the 600 Centre. With an extended magnetic table width of 500mm x 600mm long, the grinder is targeted directly at mould and die makers and press-tool manufacturers. It is constructed on a heavily ribbed meehanite casting and weighs in at 3.2 tonnes with a table load capacity of 700kg.

Digital readout on the vertical Z axis greatly simplifies set up and machine operation, and it complements the Okamoto electronic control, providing fully automatic cycles for rough- finish grinding and spark-out in a single set up.

Bridgeport Machines: Stand 5530

Bridgeport Machine’s entry into grinding technology will be marked by the first public demonstration of its revolutionary new Viper flexible grinding centre. The new machine, built at the company’s Leicester factory, is a full five-axis machine with a difference. A 30-tool changer, able to store 120mm by 220mm diameter grinding wheels, makes it possible to integrate grinding with milling techniques for total flexibility.

The Viper (very impressive performance extreme removal) is a production grinding centre which uses standard oxide-based grinding wheels to extremely good effect. Bridgeport claims that the stock removal can be up to eight times greater than on more expensive CBN wheel equipped machines and it is especially economical when handling the high-nickel alloys used in gas-turbine blade manufacture.

Jones & Shipman: Stand 5459

J&S is launching the new Dominator RT (Rapid Transfer) production grinder on its stand in Hall 5. The machine continues to build on the success of the award-winning Dominator 624, which was demonstrated at the previous MACH show.

Designed to incorporate inbuilt twin or multi-fixtures, the Dominator RT allows the operator to load and unload components while the machine is in operation, thereby removing the `dead’ time at the end of each cycle. Autoloading and palletisation are further options. The version on show is an RT/CD.

Master Abrasives: Stand 4321

Master Abrasives will be exhibiting its vitrified mounted points alongside the latest DOTCO pneumatic tools. These tools and the full range of consumables for surface preparation will be demonstrated on the stand.

Toyoda Machinery & Engineering Europe: Stand 4656

On show for the first time in the UK is the Toyoda GU4x100 CNC, a universal grinder featuring automatic indexing of the wheelhead – the first such product ever built by a Japanese manufacturer. The model is an advance on the version exhibited at the company’s in-house show last summer, but with manual deployment of the internal grinding spindle and two external grinding wheels for straight and angle approach. Now that this function is computer controlled, grinding of the most complex parts may be completed automatically.

Walter GB: Stand 5020

Live demonstrations of on-line connected tool grinding and measurement, with real-time corrective action, is the crowdstopper planned by Walter GB for its MACH 2000 stand.

By integrating its Helitronic Power Production tool grinder with the Helicheck NC4 tool measuring centre, Walter will show visitors how consistent accuracy can be maintained during tool grinding, and how detailed quality reports can accompany every tool made.
