Common Questions
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 operations.
-
Q What is the purpose of the ferrite discs in the induction coil system?The ferrite discs (one-piece type, available in four size ranges) provide optimal shielding of the magnetic field between the induction coil and the tool shank, improving heating efficiency and protecting surrounding components.
-
Q Why is a clamping ring needed in a shrink fit system?The clamping ring (Specification: SFW-C) securely holds the ferrite disc in position within the coil, ensuring stable and repeatable performance during each shrink fit clamping or releasing cycle.
-
Q What tool holder interfaces are compatible with the coolant cooling tool holders?The coolant cooling tool holders are compatible with BT, BBT, SK, and CAT interfaces in both 63A (CAT40) and 100A (CAT50) sizes, ensuring broad compatibility with common CNC machining centers.
-
Q What is the cooling emulsion SFWC-905 used for?The SFWC-905 cooling emulsion is applied to protect the shrink fit chuck against corrosion during and after the water cooling process, extending the service life of the tool holder.
-
Q Are the heating time values in the table applicable to all brands of shrink fit holders?The heating time values are based on Derek brand shrink fit holders. Since different brands vary in material composition and wall thickness, the heating time and power rate should be adjusted accordingly when using holders from other manufacturers.
