ROVI Products manufactures a line of internal expanding collets to fit 5C, 3J and 16C spindles, capable of holding on bores ranging anywhere from .065" to 6" in diameter. Our system is composed of three parts: a hardened and ground sleeve to insure accuracy; a rod assembly which consists of the threaded pull rod, 5C collet nut, lock nut and expanding screw; and the machineable expanding collet. Unlike other designs, our expanding collets have a taper on the shank that locks into the sleeve creating a very rigid collet which in turn gives you better concentricity. All ROVI collets are machineable and completely consumable (.0005" TIR is easily held on production runs and holding .0002 TIR is not uncommon). Additional advantages are greater ease of loading with the spindle in motion, less chucking interference from chips and stringy shavings, and a greater capacity for holding parts. ROVI collets save time, labor and cost because they can be remachined for many different jobs. When the collet has been consumed or needs to be replaced, simply remove existing collet from the sleeve and insert new collet. It is not necessary to purchase the sleeve and rod assembly for every new collet as other manufacturers may require.

The ROVI mini collet is a unique design which allows this collet to hold on bore diameters from.250" - .065". The mini collet is available in three different chucking lengths: 1/4", 9/16", and 3/4", all with a diameter of 7/16". In addition, a shoulder on the major diameter of this collet allows use of a turning screw for ease of machining.

Our heavy duty collet line for 16C and 3J spindles is capable of holding on bores of.750" - 6" in diameter. These collets are of great benefit, due to the larger taper of the collet and the expanding screw when used on machines which have a lot of pressure generated by hydraulic closers. The design of this system is the same as our standard one.

We also manufacture special collets to your specifications. Please do not hesitate to call us with any questions you may have. ROVI has been in business since 1965 and we are very knowledgeable in the work holding field.
