News and Updates


The great success of Levicron’s aerostatic tool spindles ASD-H25 and ASD-H25A confirm the initial thoughts of bridging the gap between Ultra-Precision and CNC Machining. With ultra-precision qualities, high speeds and CNC functionality like an automated HSK-E25 tooling system they give both machine types opportunities for new applications and markets.

Ultra-Precision Machining lacks of automation and productivity, and machining results often rely on the skills of the machine operator. CNC Machining on the other hand is characterized by a high level automation, but relies on conventional spindle solutions not capable of machining ultra-precision parts.

With Levicron’s ASD-H25 and ASD-H25A both markets get what they lack of. Ultra-Precision Machining now can make use of the automated HSK-E25 tooling system to adapt tool loaders and automated tool setting to increase productivity and machine safety. CNC Machining on the other hand now can machine optical components and high-precision parts without sacrifying CNC functionality. But to the obvious advantages of using aerostatic spindles Levicron can offer much more. Their ASD-H25 and ASD-H25A offers higher speeds at even much higher load capacities compared to other aerostatic spindle solutions and offer a thermal and dynamic stability no other solution can compete with. Especially for long machining times these spindles don’t change their properties, even when used for machining at top speed for days or weeks.

Journal Mikroproduktion covers all these aspects and gives an comprehensive overview of current applications and results with Levicron tool spindles.
