Especially for the automotive industry LED lighting solutions are becoming more and more important. Each LED cavity – and there can be hundreds in head lights – doesn’t only have to comply with ultra-precision surface finish, but does also have to reflect the light that is emitted by the LED within a defined light cone and under a fixed angle.
Legal requirements for exhaust gas emission are getting tighter and tighter. In a combustion engines it was found that the fuel injector is one of the parts with the most potential to optimized the combustion. Herein the injection hole is the key feature and the hole shape and surface finish the crucial properties. Thus high-speed spindles with a very low error-motion and low tool run-out are the key to manufacture future fuel injectors.
For both applications and more we offer ideal tool spindle solutions with ultra-precision qualities and a stable high-speed operation.
Smallest parts and highest precision combined with mirror surface finish lead to the fact that for the manufacture of mechanical watches Ultra-Precision Machining is required. On the other hand the volume requires highly productive CNC Machining with automated tool change. With our aerostatic tool spindle solutions ASD-H25 and ASD-H25A Levicron offer quite a perfect solution to what is in the Swiss Watch Industry is required. Beside their ultra-precision qualities and very a high spindle speed even “Guillochage” (special engraving technique) can be done because of the spindle robustness and the integrated rotary encoder. Because of their integrated synchronous motor teqchnology and a much higher torque at lower speeds tapping holes can be done much faster than with other spindle solutions.
For the machining of components for the most famous Swiss watches our tool spindle solutions are used with great success and results this industry never reached before.
Coining Dies are made from tool steels like STAVAX e.g. Heat tratment needs to take place before machining what actually makes grinding the right machining process. Hoever very small features and engravings only leaves milling with carbide or CBN tools as a machining process. As machinign can take days a high spindle speed is required to increase productivity as well as a stable spindle solution even at high speed over days. As our aerostatic spindle solutions don’t change their properties with time and run at very high speed at a dynamic tool run-out of under 1 micron they are the idal spindle solutions for this application.
LED Lighting required the machining of the LED cavity to reflect the light efficient and in a defined light cone. This agains means that not only Ultra-Precision machining is required to achieve sub-micron accuracies and nanometer surface finish, but also automated robust machining like it is usual for CNC Machining.
As our aerostatic spindle soltions are ultra-precise, offer CNC funtionality with HSK tooing and gives the speed and robustness to machine dies and components for LED lighting.
Precision Optics used in telescopes, microscopes or exposure units require ultra-precision turning, milling and grinding to achieve sub-micron geometries and nanometer surface finish. As it affects the form accuracy polishing often is not allowed and the part need to be used as it comes from the lathe or the machine tool. Beside the grinding of glass lenses with drastically reduced sub-surface damage ultra-precision turning and milling of optical components are the most common machining technology with our tool and work holding spindles.
The integration of functions and electrical circuits requires modern and future electronic components to be small and precise at the same time. An example are fibre optics where the optical fibre even at the connector needs to be aligned with 1 micron.
Beside the technical and electrical design manufacture and material properties seem to become the bottle neck of a further miniaturization. For tool and work holding spindles this means that beside increased speeds accuracy and stabilty are crucial to keep up with current trend on the electronics market. What are the properties of an ideal spindle to machine electronic components?
- High Spindle Speeds
- Dynamic and Thermal Stability even at top speed and long machining cycles
- Stable Properties even for long machining cycles
- Automated Tool Change
