27mm System

The 27mm Adaptable Spindle System allows the use of tubing or collets for different operations:

  • Tube machining with 5C collets

  • External machining of blanks with collets

  • Internal machining of blanks with collets

The 16C collet system provides 42mm of bar or tube capacity along with the all the features of the 27mm system.

Adaptors allow collets in 16C or 5C sizes and external and internal gripping collets for blank machining to be used.

Fast changeover, ensures no loss of time when running small batches of rings.

42mm Capacity System

We developed this system for the needs of the jeweler who wanted greater spindle capacity of 42mm (16C) without going to a larger machine footprint.

This adaptable spindle system combines the 3 configurations needed to machine wedding bands, coupled with an on machine probing system.

The machine can automatically locate the reference position for a new blank or tube.

The system includes: spindle nose, adapter plate, adapters for 5C collets, 12 mm arbor, and all necessary hardware. *Does not include inside or outside collets. External collet sets in 1/2 sizes and 1/4 size sets are available. Internal collets in 39 collet sets between 16.4 mm and 29.9 mm are also available.

All collets are made in the USA.


At RingTech, we have developed a collet system that allows quick changeover from tube collets to blank collets to outside collets, in less than 2 minutes per change.

Adaptable Spindles (27mm and 42mm) 

Ringtech's adaptable spindle system was developed to solve the problem of using inside & outside collets on the same machine without long changeover times. 

We offer 2 systems for the Hardinge 5C & 16C style collets.
