International Engineering Fair

A contract worth €1.5 million made at the fair


The company ZKL Brno and the ZKL Group, the biggest manufacturer of large-size bearings in Central Europe, confirmed at the International Engineering Fair a purchase order for a new revolving grinder technology from the specialist French manufacturer Berthiez, which is a Starrag Group Holding company. The machine will be deployed in a demanding operation on   grinding of bearings for wind turbines. Starrag Group CR collaborates with the company Ludačka Machine Tools. The contract is worth roughly €1.5 million, and the final placement of the bearing on the customer’s  premises will be carried out in the third quarter of 2017.

 It is done using soft-machining:  a damped rod is clamped in a rigid and extremely powerful multi-function machine tool. It enables a stable machining process with overhangs of up to 18xD. This significantly exceeds the capacities of steel bars up to 10xD and calibrated bars up to 14xD. The system is complemented with wireless monitoring for adaptive management of cutting conditions, interfaced with the machine control system, but also with mobile devices via bluetooth. The manufacturer has achieved a world record in machining with 18xD overhangs with wireless monitoring. This solution is entirely unique and truly competitive. It is a completely new system for extreme operations inside the workpiece in very tiny openings, such as rotor shafts of aircraft engines or chassis systems, as well as components for the mining and oil industries. This new system achieves a depth for machining by 4xD greater, i.e. by more than 20 percent,  compared with the best solution available on the market so far.
