6.4 Cooling
6.5 Special toolholders shrinking
Install the holder on the cooling station of support box.
For special toolholders e.g. tools with larger front end than shank, split heat focusing
stoppers are available. The use of those requires having clearance between tool head
and toolholder front face.
To successfully shrink/release special tools, it is necessary to observe the following
conditions :
- Maximal diameter of the cutter D is 3 x d
- Ø D maximum = Ø 63 mm (maximum bore Ø of induction unit).
- A dimension = 70 mm minimum (due to the inductor housing dimension).
- E dimension changes depending on tool shank diameter d : see chart below.
(see § 1.8.3 for the Split heat focusing stoppers Part No.).
