OCEANSIDE, CA.  - At IMTS 2022 we where visited by the great folks at GIE Media, Inc. who publish Today's Medical Developments, Aerospace Manufacturing and Design and Today’s eMobility. They asked Matt Saccomanno, the inventor of the Microconic system to give them an on-camera overview of our products and how they work.
 
As you probably already know, Masa’s Microconic Cartridge and Collet assembly is designed to vector the chucking force directly over the holding surface in your Swiss type CNC screw machine. This means that the chucking force can be reduced while at the same time the holding power is increased. This opens up the possibility of shifting part operations from the main to the sub-spindle and dramatically reducing cycle time. 20% ~ 40% cycle time reduction is commonly achieved.​

At IMTS 2022, we expanded our Microconic line of swiss type CNC machine workholding. The new push type F15M5 and F16M5 cartridges replace the standard TF15 and TF16 collets in your CNC spindle. This enables you to use the newly introduced Microconic UM5 collet series with the Micrograd Dial Wrench to achieve superior stability with precise, calibrated, repeatable setting of collet closure. The off-the-shelf Microconic system concentricity of the cartridge and collet system combination is guaranteed to be within 5µm (0.0002") in production use.

Both the F15M5 and F16M5 cartridges are a micro-workholding system for use in high precision, small diameter CNC turning applications which enables you to move more work to the sub spindle operations and reduce cycle time. ​

The F15M5 cartridge is compatible with spindles that accept Schaublin F15 76-580, E120, Southwick & Meister TF15 and Hardinge TF15 / 4607 collets, while the F16M5 cartridge is compatible with spindles that accept Schaublin F16 76-1076, E1212, Southwick & Meister TF16 and Hardinge TF16 / 4609 collets.

Along with the new smaller cartridges comes a comprehensive series of UM5 collets that are ideally suited for small diameter part sizes ranging from 0.2mm/.008" to 5.5mm/.217" in diameter. These are available in regular type UM5 collets as well as all three types of Microconic's T, V and W type Over-Grip collets. Masa Tool offers the most unique variety of over-grip collets in the industry.

And yes, if you listened closely to the video, you heard correctly, Matt spilled the beans on the new product that we'll be releasing  next: The F13M5 Cartridge.  And after that, we're going to heed that advise of "go big or go home.  Yea, that was a spoiler alert. 

Masa Tool's Microconic 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.

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.

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.
