Frequently Asked Questions
Q
What is the clamping range of the SFW-24P water cooling shrink fit machine?
The SFW-24P supports a clamping range of Φ3 to Φ32 mm, making it suitable for a wide variety of carbide and HSS tool shanks used in precision machining applications.
Q
What is the purpose of the induction coil (SFW-332)?
The SFW-332 is a universal induction coil designed for a clamping range of Ø 3–32 mm. It uses 4 ferrite discs to generate the electromagnetic field required to heat and expand the shrink fit chuck for tool clamping and release.
Q
Why are ferrite discs used in the shrink fit machine?
Ferrite discs (SFWH series) provide optimal shielding of the magnetic field between the induction coil and the tool shank. This ensures efficient and focused heating of the chuck bore, reducing energy loss and improving clamping accuracy.
Q
Are the heating times in the table applicable to all brands of shrink fit holders?
No. The heating time table is based on Derek shrink fit holders. Different brands may use different materials and wall thicknesses, so heating times should be adjusted accordingly to avoid overheating or insufficient expansion.
Q
What is the cooling emulsion (SFWC-905) used for?
The SFWC-905 cooling emulsion is applied to the shrink fit chuck after the heating and clamping process. It accelerates cooling and protects the chuck against corrosion, extending the service life of the tool holder.
Q
What tool holder interfaces are compatible with the shrink fit system?
The system supports a wide range of standard tool holder interfaces including BT, BBT, SK, and CAT40 (63A) as well as BT, BBT, SK, and CAT50 (100A), ensuring compatibility with most CNC machining centers and milling machines.
