KUVE (linear ball bearing and guideway assemblies)

Wafer sawing


For high precision wafers

During processing, silicon rods soon come into contact with a saw, for example a keyhole saw. This is where you can also find four-row miniature linear ball bearing and guideway assemblies KUME from INA.

Conditions in the feed area of wafer saws are harsh. Slurry, a mixture of silicon carbide and grease required for cutting, impairs the life of all the components involved. Just as well, then, that INA supplies KUME as standard in a corrosion-resistant design.

There are plenty of other good good reasons, however, to select INA miniature guidance systems for wafer saws: high rigidity and precision, uniformly low displacement resistance and favourable lubrication via the end pieces. What is more, you can achieve a significantly more cost-effective design than with conventional linear guidance systems. This is because we can supply you with a preloaded, ready-to-fit unit.

In keyhole saws and wire wafer saws, a large number of different movements must be supported, both linear and rotary. Technically and economically optimum solutions for all of these are available from INA - complete solutions from a single source.

Other INA bearing arrangements for this area include needle roller bearings - for applications such as high rigidity roll bearing arrangements in wire wafer saws - or slewing rings.
