LevicronAll in house developed and manufactured Ultra Precision Technology for CNC Machining
Levicron
Development, manufacture and sales of motor spindle solu�ons with non-contact bearing technologies for ultra-precision and CNC machining is Levicron‘s core business. At Levicron bespoke analy�cal proven methods and simula�on tools for structural analysis and fluid dynamics complement sound prac�cal experiences in the field of spindle development and produc�on.
Being the first ever provider of aerosta�c tool spindles with industrial tool interfaces (HSK) and full CNC func�onality, products from Levicron are being used all around the world to reliably machine precision parts with an op�cal surface finish.
Our demands of our products and those from our customers prevent the use of off-the-shelf components within the build. Therefore not only the patented bearing technology and patent-pending spring-free HSK taper clamping systems can be found in our motor spindles, but also in-house developed motor and encoder solu�ons. A ver�cal manufacturing integra�on of more than 90 % incorporates CNC turning, - milling, - diamond machining, - cylindrical /bore grinding and bespoke machining solu�ons. Along with our produc�on sophis�cated test and dynamic balancing methods can all be found under one roof.
The quality, speed and accuracy of Levicron spindle‘s and the requirements for the applica�ons they are used in have made it necessary to develop bespoke encoder and motor solu�ons as well as solu�ons for HSK tool clamping, HSK tool holding and others. Because of their unique performance and func�onality some of these solu�ons have been made available for our customers as off-the-shelf items. Although Levicron had to re-invented the wheel more than once our customers can confirm that our wheels run be�er and faster than others.
As a result, tool and work-holding spindle solu�ons for turning, milling and grinding are offered that provide a unique thermal stability and robustness at sha� dynamics, erros in sha� mo�on and speeds which were previosly not available for the user.

UTS-xUltra-Precision HSK-E Tool Holders with Thermal Shrinking Shank Clamping
The best machine and the most precise spindle solu�on is worth nothing without equally precise and balanced tool holding. To make use of the full poten�al of an ultra-precision tool spindle an ultra-precise and dynamically neutral tool holding is required. Hence DIN 69893 compliant and commercially available HSK tool holders are suitable to only a limited extend with our tool spindles.
By making use of our highly specialized manufacturing – what of course includes our spindle solu�ons – and innova�ve balancing methods Levicron was able to develop and manufacture its HSK tool holding solu�on UTS-x. For this we use the clamping repeatability, the speed and the dynamic consistency of our tool spindles to not only reliably balance our UTS-x tool holder series at 60.000 rpm, but to also to balance under condi�ons very similar to those in a later machining process.
In compliance with DIN 60893 and for the first �me ever ultra-precision HSK tool holding with the following proper�es can be offered to our customers with our tool holder series UTS-x: *):
Sta�c Tool Run-Out: < 0.8 micron
Balancing Quality: < G0.3 mm/s, 60,000 rpm
Repeatability, axial/radial: < 0.2 µm
While tool run-out is reduced by 70 % balancing quality is even more than 25 �mes be�er than the industry standard.
Hence our slogan: “Ultra-Precision meets CNC Performance“
