We see from your search that you're looking for information on the term "Grinding Wheels",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release Machine grinds tools as small as 0.5mm diameter from
Anca Pty, which we summarised at the time by saying "A CNC tool grinder is designed for grinding small cutting tools with diameters as low as 0.5mm having overcome problems of vibration, thermal growth, wheel wear and tool run-out".
A few weeks before,
we featured the news release 5-axis machine grinds different broaches from
Schneeberger, J: "For grinding flat, cylindrical or helical broaches, a 5-axis machine produces exceptionally high accuracies owing to the machine's rigid and robust construction".
In December 2007, we covered the news from Vora Industries
concerning its Solid carbide and HSS tooling
- take a look at Advanced machining produces carbide cutters
which says: "Indian manufacturer of solid carbide and HSS end mills, roughing end mills and through-coolant drills uses advanced CAD systems and the latest CNC machine tools".
Take a look also at the news release from Hardinge Machine Tools, Flexible machines grind turbine components,
as well as Grinding crankshaft pins and bearings in one from Emag UK,
and CBN form grinding wheels offered from Engis (UK).
