Pressure sleeves are an important part of the clamping system and are installed in the spindle of the CNC lathe. They can be manufactured in different versions. For overgrip collets the taper angle of the pressure sleeve can be adjusted. Used or worn pressure sleeves can be reground or reworked within shortest time. Another possibility is to reduce the pressure sleeves, so it is possible to produce on the same machine with a smaller type of collet. There are no customer-specific limits, as pressure sleeves can be manufactured according to drawings as well as samples.
