OCEANSIDE, CA. Masa Tool has expanded their line of Microconic over-grip collets to include a new style called a "T-type." The T-type over-grip collet has a longer gripping surface than the original W-type. We designed it specifically for longer parts such as bone screws with wide pitch threads.
But, in some cases, with longer parts, the land width "B" needs to be longer to support the workpiece properly. Masa's new T-type collet provides the solution for longer workpiecesTypically with over-gripping applications, a shorter land length/clamping pad length/grip length is desired because of limited space available to hold the workpiece behind the enlarged head or flange that it is reaching over. That is what our original W-type collet was optimized for. However, with longer parts, with more surface area for clamping and gripping room, a longer land length is often preferred to provide more stability to support the longer length workpiece.

 FOR IMMEDIATE RELEASE OCEANSIDE, CA. - Masa Tool is excited to announce the introduction of the game changing Microconic workholding system for use in sub-spindle swiss machine operations at the Precision Machine Technology Show April 25- 27, 2017, booth 1222. This will be the first time that Masa Tool has exhibited at PMTS. The Microconic system is unique because it enables operators to move work from the main to the sub spindle and balance out part production. The Microconic system opens up cycle time reduction opportunities that have not been able to be considered previously. The Microconic system consists of two primary components: a cartridge that fits in the machine’s standard TF20, TF25 or 5C collet closer, and the Microconic collet itself, which fits into the proprietary cartridge. Each cartridge model, is designed with an extended nose and can accept either a standard or an over-grip collet made by Masa Tool. Standard Microconic collets can accommodate workpiece diameters ranging from Ø0.008 inch /0.2 mm to Ø0.394 inch /10 mm. Also being introduced is the Microconic™ Over-grip collets that can accommodate diameters from Ø0.020"/0.5mm - Ø- 0.283"/7.2mm. Over-grip collets open up to 0.157"/4mm larger than the clamping diameter. The extended nose design directs all of the chucking pressure is directly over the workpiece. Total indicated run-out (TIR) for the Microconic system is guaranteed at 0.0002"/5 µm at the workpiece, absent any runout introduced by the machine structure or other elements of the setup. The Microconic system comes with a Micrograd face-dial wrench providing operators full control of setting the chucking pressure. Operators no longer need to rely on the “feel” involved in tightening the collet. The Micrograd features micrometer like graduations of 0.001"/0.02 mm to aid operators in "dialing in" the perfect closure on a workpiece.  |
