Fastest Bearing Finish in the World
New KM 90 evo from Thielenhaus(PresseBox) ( Wuppertal, )
Due to the extremely short auxiliary process time of 0.9 seconds, the KM 90 evo is currently able to achieve the quickest roller bearings finish processing in the world. The floor to floor time can be a sensational 3.5 seconds under the conditions of a direct link with an upstream grinding machine, for example, a deep groove ball bearing of an outer and inner ring Type 625. Furthermore the changeover time between two good parts can be reduced to less than 20 minutes. The new fast runner for mass production can even be flexibly converted from radial to axial bearing rings and from ball bearing to roller bearing processing.
With the optionally available HyperFinish technology 2.0, up to 30% shorter cycle times can be achieved by overlapping the main oscillation with an additional high frequency oscillation. Thanks to the increased productivity, you will be able to do without additional machining stations and/or machines, resulting in operational cost savings. Due to the reduced oscillation angle, quality and shape parameters are also improved so that optimal dimensional accuracy can be achieved, particularly with 4 point bearing rings, for example.
The direct drive radial oscillation for ball bearing rings makes it possible to adjust the oscillation and approach angle, as well as oscillation frequency and stroke using the program. With the changeable direct drive for linear oscillation for roller bearing rings, the adjustment of the linear stroke can also be recorded in the program. This also applies for the X-Z track position.
The menu and image-driven programming with automatic program generation and calculation of the process parameter speed and stone grinding pressure from known indicators of cutting speed in m/min and specific grinding pressure in N/mm² makes for easier handling of the machine. Menu-driven set up is also optionally offered. An innovative compensation for wear on the workpiece driver makes it possible to use reground drivers and significantly reduces tooling costs.
The option of time recording for setbacks even with the KM 90 evo, demonstrates that Thielenhaus has developed in the direction of Industry 4.0. The machine comes with an integrated control cabinet in the extraordinarily compact dimensions of 2,063 x 1,026 mm so that it can even fit in spatially limited production chains.
