The Slim Chuck is available to suit all processes with numerous shank sizes, lengths and configurations available. The Slim chuck body shape is avalable in two configurations: Standard parallel SK and externally tapered SKT. These two forms allow versatility to suit most applications and requirements.
The scope for the Slim Chuck can also be extended to NIKKEN's Multi-Lock Milling Chuck by using the 'straight shank' Slim Chuck in conjunction with a Multi-Lock which, in this case, then becomes a rigid and reliable base holder.
As is common for several products the standard Slim Chuck features a notched nut requiring a flat/hook type wrench and the ‘high speed’ variant is smooth too suit the ‘GH Handle’ roller bearing wrench. Unlike the Multi-Lock the Slim Chuck absolutely requires a collet. A collet first requires selecting and loading into the nut (direct chucking is not possible).
Slim Chuck, depending on tool shank, is available in 6 sizes:
-
SK6 - to suit diameters 0.7mm to 6.0mm.
-
SK10 - to suit diameters 1.75mm to 10.0mm.
-
SK13 - to suit diameters 2.75mm to 13.0mm.
-
SK16 - to suit diameters 2.75mm to 16.0mm.
-
SK20 - to suit diameters 3.5mm to 20.0mm.
-
SK25 - to suit diameters 7.5mm to 25.4mm.
The Slim Chuck currently has 4 types of 8 degree collet available to select from to hone and fine tune both accuracy and coolant control. They are:
-
Standard Collet - Example SK16-16 (Maximum 0.5mm collapse & 5 microns accuracy).
-
Precision Collet - Example SK16-16P (Maximum 0.5mm collapse & 3 microns accuracy).
-
Milling Collet - Example SK16-16A (No collapse & 3 microns accuracy).
-
NEW Mechanically Sealed Coolant Collet - Example SK16-16AC (Designed for coolant hole cutters. No collapse & 3 microns accuracy).
The standard, precison and milling SK collets can also be used in conjunction with our 'Jetter' system. By selecting the appropriate optional 'Jetter' nut and cap it is possible to control the coolant supply to suit your specific process - depending on the cutter type and requirement.
