Hard turning or grinding? This debate has been ongoing for years. Each technology has its advantages and can fully demonstrate its strengths within the right machine concept. Originally developed by the American machine manufacturer Hardinge, the high-precision turning machines of the SUPER-PRECISION series are bringing hard turning into the spotlight. Thanks to their rigidity and stability, they are ideal for high-precision hard turning, as well as for combined hard turning and grinding operations, enabling the production of complex workpieces in a single setup.

The high surface accuracy achieved in high-precision hard turning on SUPER-PRECISION machines allows for complete workpiece machining. This eliminates the need for a grinding process and, consequently, the need to reposition the workpiece onto a grinding machine. As a result, machining times are reduced, and process reliability is increased.

A 45° solid cast iron machine bed, filled with polymer concrete, provides exceptional vibration damping – a crucial factor for achieving micrometer-level precision. Centrally positioned oversized ball screws and compact multi-row linear guides ensure that the forces generated during hard and high-precision turning are effectively absorbed.

With numerous options such as tool and workpiece measurement, grinding attachments, workpiece collection devices, bar feeders, and automation solutions, each machine can be perfectly tailored to its specific application.

The brand SUPER-PRECISION is now part of the portfolio of the Swiss grinding technology group Kellenberger Switzerland AG. As a result, it benefits from the innovative strength that also extends to the brands KELLENBERGER, VOUMARD, HAUSER, TSCHUDIN, and USACH. This ensures continuous technological advancement, driving each of these brands forward in their core competencies and maintaining their market leadership in their respective fields.
