Collet chucks for CNC routers

A collet chuck for CNC routers is a device installed in the spindle unit to fix the cutting tool using collets and transmit torque to it. Such equipment is used in drilling, milling, coordinate machines, machining centers and other equipment. The Stancomplect online store offers for sale collet chucks and milling heads directly from the manufacturer.

Features of collet chucks

Chucks designed for clamping axial cutting tools have:

1. A simple design that allows for quick and secure fixing of drills and cutters.
2. High-precision self-centering of the tool with guaranteed absence of axial displacement and radial runout of no more than 0.005-0.02 mm.
3. Precision machining of contact surfaces.
4. The ability to install adapter sleeves to use collets of a different size, since each collet chuck for a CNC router is designed for a collet of one diameter.

Operating principle of collet chucks

The collet is inserted into the clamping nut of the chuck so that it rests against the outer flange of the nut and is fixed in it. When the nut with the collet is screwed on, the chuck runs onto the conical surface of the split sleeve, causing its petals to compress and firmly squeeze the tool shank or workpiece.

Types of Collet Chucks for CNC routers

Collet chucks for CNC routers can be divided into three types according to the type of cone inserted into the spindle:

• 7:24 ISO – these are chucks for spindle speeds up to 30,000 rpm;
• 1:10 HSK or KM – for speeds of 40,000-50,000 rpm;
• 1:19-1:20 PSK Capto – polygonal cone, premium analogue of HSK.

ISO collet chuck is divided into three subtypes:

• SK (DIN 69871), used on European CNC equipment;
• BT (MAS 403), used in Asian countries;
• NT – (DIN B 2080), used for machines with manual tool change.

HSK collet chuck can be divided into types:

• A, B, C and D – for low speed machines;
• E and F – for high processing speed;
• T – for lathes.
