That happens in usually 2% of the feed. If the lining is used above 60 ° C Seal will be
damaged.
There are fodder based on fat instead of oil, which can sometimes reach up to 80 °
C.
Why are there collet holders with the HSK63F
ball-bearing nut and which ones without?
With the ball bearing of the clamping nut, the friction when tightening the chuck is
reduced. This means that less elastic force is lost through friction. Most collets should
be tightened to at least 100 Nm and a torque wrench.
What is the advantage of a hydraulic expansion chuck?
If you have to change often (daily) the change is very comfortable and easy. In
addition, the oil damping in the chuck protects the spindle of the CNC machine. The
concentricity accuracies are in the range of 0.004mm. The harder the material that is
milled, the more advantageous the damping is for the life of the tools. With soft
materials that are milled on CNC machines, the holder plays a subordinate role. The
vibration amplitude that occurs when the tool enters the mold is dampened more
quickly.
Does a thermal lining also have cushioning?
Yes, it mainly dampens with the mass of the holder.
What else can you say about hydraulic expansion chucks?
The tolerances of the shaft should be at least small h7, better be small h6, with
diameters that are too small and tolerances too high, the chuck can be damaged.
Because then the membrane is overstretched.
Anyone who uses constantly changing suppliers and different diameter tolerances is
better served with collets. These are less sensitive to shaft tolerance.
