HSC-Technology

The term HSC is often used - what does it mean?

HSC stands for: High Speed Cutting.

Cutting pressure is much less when using high speed. Therefore HSC functions
at a much higher speed for the workpiece feed and for the cutting speed
compared to conventional cutting methods.

A little experiment will make this clear: When holding a paper freely in one hand
and trying to cut it with the other hand this will result in a difficult task with an
untidy cut when doing so at low speed. However, a high speed-cut with a
machete for example will bring a much better, tidy cut.

Accordingly, the advantages of HSC are enormous versus conventional working:

The quality of the surfaces rises in an outstanding way.
The carrying-off of heat above the chips (before any heat might be
     transferred to the material) even allows the milling of hardened steel.
     Also the treatment of hardnesses up to HRC 65 is possible with a coated
     hard metal milling cutter.
The gyroscopic effect stabilizes very long and very thin tools and the
    processing time drops drastically.
Never expected polishing qualities become real.
Expenses for the secondary treatment fall considerably.

Surely, all of Wissner´s high-dynamic machines posses all features needed for
HSC processes. Such high speed is also possible at complex surfaces and at
very fast milling spindles which are needed for the necessary number of
revolutions for small tools.
The correct acceleration is of most importance for the use of HSC-technology
while the chart speed alone is less relevant. Otherwhise the machine would
have to slow down considerably without ever reaching highest speed for
complex figures. Normal values are 0,2 g or 2 m/s² expressed differently.
Good HSC-machines reach 1g what means 10 m/s². Wissner´s version
HIGH PERFORMANCE makes even 2 g - this is surely forward-looking!
