Spindle extension - Import export

The spindle extension SamSpindle, has been specially designed for the extension of lathe spindles. Together with the bar feeder Multi 3000 it forms a safe, clean and efficient solution. The SamSpindle operates oil and air free. There is no mechanical connection to the lathe. Only a minimum of moving parts and masses. These are: the rotating bar, the guide rings and the inner cage of the ball bearings. The guide rings mounted in the roller bearings keep the bars in the centre of the SamSpindle cartridge. Thanks to this technique, round or test bars can be rotated at high speed, ensuring remarkably smooth running. You can turn drawn, round or profile bars, with correct straightness, at the maximum spindle speed of the lathe. This allows us to guarantee workpieces with high precision. The SamSpindle spindle extension offers maximum safety. It does not allow access to parts in motion. The moving parts are all enclosed in the SamSpindle cartridge, which is closed by a safety nut.

The arrangement of two oscillating heads working in opposite directions results in an unusually light construction for a resonance testing machine with a nominal load of 500 kN. With the double spindle arrangement, the overall height could also be kept relatively low. The clamping length is adapted to the customer's needs by means of spindle extensions.
