"In order to further optimize the bit manufacturing process and save cycle times, Schlenker equipped the Swiss-type lathes with the Masa Tool. The overlapping collet from the manufacturer and Schlenker partner of the same name makes it possible to grip turned parts with a diameter difference of up to four millimeters, regardless of the machine's available path. As a result, the counter spindle can be regarded as a full spindle. Depending on the geometry of the workpiece to be machined and the possibilities of the machine, this results in enormous savings in cycle times."

​"The Masa Tool consists of a basic body and, in this case, overlapping collet in a T version. The use of this collet makes sense if the diameter to be clamped is smaller than the diameter to be overcome. This enables a concentricity of 5 μm."

"The system is used in the counter spindle and can be precisely adjusted on the machine. For this, Schlenker offers the micro-degree setting ring, which enables the microconic collet to be closed in steps of 0.02 mm. This setting is then held by the basic body. Andreas Stengele: “Normal collets are set according to the feeling. With the Schlenker system, I can define exactly how far you can tighten it for the ideal tension. ”The closed system is made of spring steel and is very flexible. "We have been offering the system for over two years and have never experienced a break," emphasizes Eugen Belz."
