New Precision Chucks for Micro Machining
For the smallest and finest surfaces
In micro applications, the demands on accuracy of the components that need to be machined are very high. Therefore the Albrecht Präzision GmbH & Co. KG, located in Wernau, has expanded its product range with the Micro Precision Chuck. This allows operators to clamp tools with diameters of one to six millimetre variably, safely and with high precision. It ensures an ideal concentricity, is slim and maintenance-free.
The new Micro Precision Chuck is available in various lengths and is characterized by a very slim interference contour of D1=13.5 mm. The operator can choose between peripheral and central cooling. Peripheral cooling, for example, increases the process capability through an additional cooling and rinsing effect. Compared to a shrink fit chuck, the new micro precision chuck shows significantly better damping properties. The perfect concentricity of ≤ 3 μm 2.5xD and the high clamping force ensure a high process reliability. Because of its slim design, it is also suitable for hard-to-reach processing areas. The Micro Precision Chuck reaches a rotational frequency of up to 40,000 rpm. Further to this the new collet is designed with a flat cone angle and a second cylindrical guide in order to achieve a high clamping force, bending rigidity and precision. The included internal hex key ensures easy opening and closing. In addition the collet is specially coated, which significantly extends the service life.
Suitable for the various machining centres and milling machines, the chucks are available with tapers according to DIN 69893 (HSK), for tool holders JIS B 6339 (ISO 7388-2) (MAS BT) and DIN 69871 (ISO 7388-1).
