Due to the extremely short auxiliary process time of 0.9 seconds, the BearingStar 90 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.
Thielenhaus Microfinish
Thielenhaus Microfinish, a division of the German Thielenhaus Technologies GmbH, has been building high-precision, high-productivity machine tools for over 110 years. In the last 70 years, Thielenhaus Microfinish has become the leading manufacturer of extreme-precision machine tools for Microfinish/Superfinish and double-disc grinding applications.
Microfinishing, also known as superfinishing or short-stroke honing, is the ideal machining process for achieving extreme precision surfaces and component geometries, and removing amorphous surface layers in the magnitude of 2 µm. Honing stones, cup wheels and microfinishing tape or film can be used to generate surface roughness or geometrical accuracy within a previously defined window that often spans a few tenths of a micron. Indicated below are a number of parameters which can be optimized using Microfinish:
With facilities in Europe, America and Asia and a worldwide service network, Thielenhaus has adapted itself to the market conditions and to the customer needs all over the world.
Commitment to quality: Thielenhaus machines are employed by leading manufacturers across the world for a good reason – their high reliability, productivity and production quality. Thielenhaus continuously pushes the limits of precision machining, enabling its customers to achieve workpiece qualities that were previously impossible.
All solutions from a single source: Extreme precision is the specialty of Thielenhaus, and over the years the manufacturer has built the world’s largest portfolio of Microfinish solutions, ranging from industrial equipment for large and small manufacturers to just-in-time tool delivery and other services. When it comes to Microfinish Thielenhaus is the one-stop shop.
The flexibility of Thielenhaus is its customer’s advantage: The manufacturer adapts the machine solutions to the customer’s component, loading/unloading preferences, cycle time requirements and other specific needs. The modular design of the machine platforms accommodates even tricky components.
New challenges and innovation are the passion of Thielenhaus: They are proud of their 430+ patents in surface finishing technology as well as of numerous market-leading platforms and pioneering innovations. Thielenhaus constantly seeks to improve the machining concepts, always keeping in mind the challenges of tomorrow.
Customer support all over the world: With customer service locations in six countries and service agreements with a network of agents and distributors, Thielenhaus is able to provide quick service on short notice practically anywhere in the world. The customers also benefit from a 24/7 hotline and Online Direct Service.
Thielenhaus is known as a highly experienced problem solver: Anyone can be a problem solver, but with more than 70 years of developing Microfinish solutions, the Thielenhaus staff have probably seen and solved more Microfinish problems than anyone else in the industry. When it comes to splitting microns, the Thielenhaus in-depth knowledge of the microfinishing process is unsurpassed.
