Introduction
We don’t put our name on anything but the best.
High-volume turning requires tough, consistently accurate collets and collet chucks. What better name to trust than Riten, respected around the world for quality work holding products
Riten Collet Chucks are precision ground with guaranteed repeatability of .0002” TIR. Tolerances are held uniformly from the mounting to the working collet taper. Our products include both power and manual chucks with dead length or pull back operation. These chucks are ideal for first or second operation chucking.
Riten Collets are designed for improved accuracy and repeatability, superior gripping power, and extended service life. To achieve this, we load the collet with an induction coil at the base of the slots and heat the collet to a glowing red hot temperature. A spreader is inserted into the slots and pushed down on the collet face. After cooling for one to two minutes the spreader is removed and the collet cools completely. This process gives our collets a spring of .010” and drastically improves the life of the collet. Few other manufacturers go to this length to ensure a quality collet.
You’ll also find Riten collets are easier to attach, because we mill off the thin top edge of the threads to prevent binding in the radius of the female thread.
Collet Chucks or 3-Jaw?
For accurate, high-volume turning of bar stock or other parts under 3-1/8” in diameter, your best bet is a collet chuck. Why?
- Consistent centering. Collet chucks grip the workpiece around the entire circumference, with no slippage when the stock is regripped, and less risk of deformation to thin-walled workpieces.
- Better tool clearance. Short or thin parts can be machined closer to the chuck face for better accuracy and less distortion.
- Higher speeds. Compact, lightweight collet chucks have a greater tolerance for high centrifugal forces, hold their gripping force more consistently, and reduce the load on machine spindle bearings.
- Longer life. In high-volume production, collet chucks have proven to have a consistently longer service life than 3-jaw chucks.
The Riten Selection
Riten Collet Chucks are precision ground with guaranteed repeatability of .0002” TIR. Tolerances are held uniformly from the mounting to the working collet taper.
Riten offers three basic types of power collet chucks:
- Pullback. Simple, one-piece design used on standard lathes.
- Set Length. Used where precise pick-off is required. Little or no axial part movement.
- Setrite®. Set length chuck with ultra-fine four-screw adjustment feature. The most accurate chuck in the metalworking industry.
Our set length series includes special short-profile models using the versatile Multibore collet, and three labor-saving quick change chucks with pre-loadable bayonet caps.
NOTE: All collet chucks require a drawtube adapter to fit specific machines.
Unique Manufacturing Process
Riten size-for-size collets (5C, 16C and R8) are designed for excellent accuracy and repeatability, superior gripping power, and extended service life. To achieve this, we load the collet with a coil at the base of the slots, heat the collet to a glowing red, insert the spreader into the slots, and push down on the collet face. After cooling for one to two minutes, the spreader is removed and the collet cools completely. This process gives our collets a spring of .010” and drastically improves the life of the collet. Few other manufacturers go to this length to ensure a quality collet.
You’ll also find Riten collets are easier to attach, because we mill off the thin top edge of the threads to prevent binding in the radius of the female thread.
Special Models
For bar work, the Multibore collet gives you great flexibility. Just 12 collets provide every size for 1/8” to 3-1/8”. Multibores are segmented to close parallel for uniform gripping on undersize or oversize bars, with no marring of the finished parts.
For second operation, the B Type Spring Collets are ideally suited for short gripping with both Multibore and Quick Change power chucks.
