Machines surface grind hard, difficult
materials
High specification electronic machines with advanced control systems have been developed to surface grind the harder and more difficult materials as well as traditional steels.
Developed for the automatic surface grinding of harder and more difficult materials as well as traditional steels, the latest Okamoto DXB range of surface grinders will be represented on the 600 Centre stand at MACH 2006 with the ACC 63DXB This new generation of high specification electronic machines incorporates Okamoto's in-house control development that features digital readout for vertical and cross traverse and electronic pulse generators to replace the conventional cross-feed handle for manual movements

Robodrill produces savings within three months
Within three months of installation a Fanuc Robodrill, Raytheon Marine Company based in Portsmouth calculated savings of GBP6,000 on components it produced due to faster set ups.
Wire EDM machine uprated to cut quicker
Fanuc has extended the capacity, specification and performance of its Robocut Alpha-1iA wire cut electro discharge machine (EDM) to provide high accuracy performance cutting at up to 300mm2/min.
Fully automatic grinding cycles are easily initiated from the new touch panel control.
Okamoto is the world's largest manufacturer of surface grinding machines and has brought its expertise to bear in creating a heavy duty and rigid grinding platform from the heavily ribbed Meehanite castings produced within its own high technology foundry.
This 3.5 tonne machine has 'double vee' guideways for both longitudinal and cross-feed axes that further emphasise the basic structure of the machine to provide the combination of heavy duty stock removal while maintaining the ability for ultra-fine surface finish to high orders of flatness across a wide range of materials.
Longitudinal and cross-axis travels on the 63DXB are 750mm by 340mm and the magnetic chuck size is 600mm by 300mm.
Table load including the magnetic chuck is 420kg making it ideal for mould and die type applications.
While the standard 'daylight' distance between table surface and wheel is between 22.5mm and 322.5mm, this can be extended as an option, to 522.5mm.
Grinding wheel size is 355mm by 38mm by 127mm with an option to increase the wheel diameter to 400mm.
The spindle is powered by a 1,500 rev/min, 3.7kW motor however, as a further option, this can be upgraded to 7.5kW.
Automatic downfeed, traverse and plunge cut can be set between 200mm/min and the rapid feed rate of 1000mm/min and table feed rate between 300mm/min and 25m/min.
For precise setting of size and to maintain surface finish requirements, up to 99 spark-out settings are available and cross-feed rates are totally programmable between zero and 1000mm/min giving maximum flexibility.
Intermittent cross-feed rates are 0.5mm to 20mm.
