REGO-FIX USA has expanded its range of tap collets for its industry-leading powRgrip® toolholding system. Now available with ANSI sizes for the PG15 and PG25 series, these collets deliver the low total indicated runout (TIR) of <0.0001" (3 μm) and precise length adjustment and repeatability of <0.0004" (10 μm) for exceptional surface quality and complete process security for challenging tapping operations.
The expanded range of ANSI tap collets is fully compatible with existing powRgrip holders and only require shanks with tolerances of h9 or better. Manufactured with an internal square, these collets are specifically designed for use on CNC machines with synchronized machine spindle speeds and feed rates. The new PG15 series includes five tap collets ranging from 0.141" in diameter with a 0.110" internal square to 0.225" in diameter and a 0.191" internal square; PG25 series tap collets come in three sizes ranging from 0.318" in diameter with a 0.238" internal square to 0.381" in diameter with a 0.286" internal square.
The powRgrip system generates extremely high clamping forces equal to or higher than shrink-fit holders for safe, precise and cost-effective toolholding. Unlike other clamping systems where heat or hydraulics are used to expand the material, powRgrip uses the mechanical properties of the interference between the holder and collet to generate tremendous clamping forces. As a result, REGO-FIX guarantees the T.I.R. of a properly maintained powRgrip holder and collet will not exceed 0.0001" and the impregnated surface treatment will not erode for five years or 20,000 cycles.
Related Glossary Terms
- collet
collet
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- mechanical properties
mechanical properties
Properties of a material that reveal its elastic and inelastic behavior when force is applied, thereby indicating its suitability for mechanical applications; for example, modulus of elasticity, tensile strength, elongation, hardness and fatigue limit.
- tap
tap
Cylindrical tool that cuts internal threads and has flutes to remove chips and carry tapping fluid to the point of cut. Normally used on a drill press or tapping machine but also may be operated manually. See tapping.
- tapping
tapping
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
