With the increasing growth of torque motors in various sizes and due to the wide range of their speed and torque bands, the production and use of direct-drive rotary tables have also become more and more common.

Features like their range of speed, relatively high torques, precise positioning ability, and non-use of elements such as face gears or rack and pinion actuators have added to the popularity of these tables. … more

Super-precision hydraulic expansion mandrels are a very precise and suitable alternative for grippers and fixtures available on the market and/or designed for specific purposes. One of the problems in material removal, in highly precise parts, is the need for high alignment, which can easily be achieved using this kind of mandrels. Achievement of precise geometric parameters in the mass production of thin-walled bushes in the automotive industry is among the reasons why they use this kind of mandrels. …more

Benefiting from ball bearings Series 7000, belt driven spindles provide the capability of rotation up to 14,000 rpm continuously. Their simple and rigid design reduces the runout of the spindle nose to less than 10 µm. Consequently, in cases where the application is sensitive to concentricity, they can acceptably guarantee the circularity factor. …more
