We have just released the NEW 2018-2019 Masa Tool Catalog! Our first batch of new catalogs is shipping directly to our IMTS booth in Chicago for release, but you can download your own copy right here!

Set ups are quicker and more repeatable with Microconic™. You can document the micrometer-adjust collet closure in your set up plan so it's done the same every time, regardless of operator skill and without relying on "feel". ​

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.

Typically 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.

Microconic’s cartridge is made of exotic high-chromium tool steel, triple tempered and cryogenically treated to provide stable construction. All functional seating surfaces are ground with extreme precision on a one-piece, ultra-rigid body structure.

“The cartridge can be used as a calibration gage to verify the machine spindle accuracy,” Co-owner Chip Prescott notes.

Microconic collets are finished to exacting standards with a five-step grinding process that removes the effect of heat-treat warpage. Also, the proprietary Microconic form of the closure surfaces is inherently more accurate than traditional collets, providing for a greater full-accuracy working range.

Cartridges are available to fit in push-type dead-length collet closers and also draw-type closers: F20M10 (for TF20 collet replacement), F25M10 (for TF25 collet replacement), and 5CM10 (for 5C collet replacement). All of these cartridges use the same Microconic UM10 collets, with more cartridge sizes in development to be released soon.

Masa Tool is introducing its Microconic workholding system for use in subspindle Swiss-type machine operations, enabling the operator to switch operations from the main to the subspindle so that usage is balanced. This capability is said to reduce cycle time in ways that are not possible with conventional collets.

​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 collet itself, which fits into the cartridge. Each cartridge model has a solid extended nose and can accept both regular and over-grip collets. The over-grip collets open up to 0.157" (4 mm) larger than the clamping diameter.

​The Microconic cartridge’s extended nose design directs all of the chucking pressure directly over the workpiece for concentricity and rigidity. Total indicated runout (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 system capacity ranges from 0.008" to 0.394" (0.2 to 10 mm) in diameter, with all sizes available from stock.

A proprietary grinding process and the application of clamping force exactly where it’s needed ensure secure, concentric gripping with a collet system that can potentially fit every turning machine in a shop.

Finally, overgrip models that expand 0.157 inch (4 mm) beyond the clamping diameter enable reaching over and gripping the part behind large-diameter areas. ​

We where honored and privileged to be interviewed by IMTStv during the show in 2016! It enabled us to get the word out about our Microconic workholding solution that solves clamping problems that have never been solved before!

​We discussed that many many people had just given up on trying to find a solution for balancing out production between the main spindle and the sub-spindle years and years ago. We where even more excited than most of the people that stopped by our booth to learn that we had indeed invented something that fixes the problem! 

Our first IMTS show was a tremendous success!  We got to meet many many new customers and where very pleasantly surprised by all the industry media people who stopped by to visit us at the show.  We had an awful lot of people comment on the "Game Changing Workholding for Small Parts" by asking us "What's so game changing?"  After they learned about the entire Microconic system we often heard them say "Wow! This is REALLY a game changer!!"

On Thursday, Harry Moser from the Reshoring Initiative visited us and we talked about how our products where developed right from our experience on the shop and because of the machining that is done locally in the Oceanside area.  The video was posted live on our Facebook Page and you can find right here down below on the left.

Be sure to keep an eye our for some articles in some pretty big name magazines in the next few months.  We're now on the look out for some application stories for them based upon the success you've had with our product.  If you have a story to tell us be sure to leave it in the comments below or contact us so we can get all the details!
