Kern introduces HSK 40 spindle Micro for greater small part productivity

Kern has introduced the Kern Micro precision machining centre equipped with a through-coolant HSK 40 spindle. Described as an ultra compact all-rounder, it is capable of full simultaneous 5-axis machining and, with the HSK 40 spindle, is able to accommodate a wider range of toolholders than other machines in the Kern range.

A 500 to 42,000 rpm 15 kW motor provides the 4 m2 footprint Kern Micro with a balanced combination of torque and high spindle speeds for machining small parts up to 350 mm diameter by 220 mm high. The large working envelope is attributed to intelligent configuration of the fourth and fifth axes that provide a wide swivel range to utilise the full working area. The HSK 40 interface has been an optimised for chip removal to allow larger tools to be used for shorter machining times. With the HSK 40 the end-user has the option of either 18, 90 or 186 tool positions while 20, 101 or 209 tool stations are possible with an HSK 25 equipped model. Kern is now also offering great flexibility for tool selection with a 'tool cabinet' that presents all tools for automatic changing. Alternatively, using patented quick-change pallets, complete tool sets can be put together for specific jobs and stored in an additional cabinet. This clear glass cabinet not only provides operator visibility, but also significantly improves tool change times. The Micro boasts a positional accuracy of ±0.5 microns. To achieve such tolerances, the critical elements, such as coolant, electrics, spindle and all axes, are all maintained at a constant temperature of 20°C.
