Linear ball bearings

Drilling and Milling

We provide the correct drive

Can you imagine making a slot 216 metres long in your cellar wall every hour? Especially if this is not even one millimetre wide? A never-ending task for a human being. No problem for a milling/drilling plotter in circuit board prototyping.

In each machining operation, the drilling and milling head moves about rapidly and with high precision, continually undergoing acceleration and deceleration. It is as if linear ball bearing and housing units from INA were made for these requirements. Thanks to the smooth-running linear ball bearings, the INA shaft guidance system requires little energy to start moving again quickly after each operation.

And since everything is from a single source, the individual components – bearing, shaft and housing – are matched to each other to an optimum degree and are ready-to-fit. Naturally, this INA design is completely maintenance-free.
