Everything you wanted to know about the Microconic #Workholding System

10/11/2016

Matt Saccomanno, the inventor of the Microconic Workholding system discussed how it works at IMTS 2016.

Masa Tool has developed the Microconic™ system specifically for holding workpieces from Ø0.15mm to 10mm (Ø0.006" to 0.390") in any machine that has a collet-type chuck.

The system consists of two major components: The Microconic™ cartridge, which fits into your CNC machine spindle replacing the standard 5C, TF20 or TF25 collets, and the Microconic™ collet, which fits in the Microconic™ cartridge.

The Microconic™ system has unsurpassed concentricity: Our manufacturing tolerance is 3µm (.0001") and we guarantee our cartridges to be within 5µm (0.0002") in production use in your machine.

The Microconic™ system works with either draw-type or push-type standard collet systems that are in any machine.

The Over-grip collet capabilities of Masa Microconic™ System, introduces a whole new world of time saving opportunities awaiting. Our Overgrip Collets open up to 4mm (0.157") diameter larger than the clamping diameter.

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 Sunday, we where interviewed on IMTStv and had some time to talk to the great folks from AMT about our Microconic system technology and where heard from people that we where on the big screen throughout the show.

We're keeping an eye on YouTube to see it and we'll be sure to share it here when we find it. :-)

We really can't express enough thanks to the folks over at Citizen for using our Microconic system on their new L20 machine with low frequency vibration technology that was on display in their booth. The application engineers sent quite a few people over to our booth once they saw it in the machine!

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!

Microconic System to be Unveiled at IMTS 2016: W-2232

8/3/2016

0 Comments

Make plans now to visit Masa Tool at the IMTS 2016 Booth W-2232 and learn about our new Microconic Workholding System.

The Microconic™ work holding system is a mechanically actuated micro-workholding system for use in high precision, small diameter CNC turning applications.

The system consists of two major components: The Microconic ™ cartridge, replaces the standard TF20 collets and fits into your CNC machine with no modifications to the spindle required. The second component to the system is the Microconic™ collets which have capacities of 0,22mm - 10,00mm ( 0.0086" - 0.3949") and -Over-Grip collets which can open up to 4mm over the chucking diameter and run within 5 µm/.0002" TIR

It's the first and only workholding system for the micro-machining industry.

Masa Tool Introduces the Microconic™ Over-grip Collet

Masa Tool has developed the Microconic™ system specifically for holding workpieces from Ø0.15mm to 10mm (Ø0.006" to 0.390") in any machine that has a collet-type chuck. The system consists of two major components: The Microconic ™ cartridge, which fits into your CNC machine spindle replacing the standard 5C, 16C, TF15, Tf16 TF20 , TF25 or TF37 collets, and the Microconic™ collet, which fits in the Microconic ™ cartridge.

Part of the standard offering of Micrconic™ collets is the UM10W Over-grip series. The UM10W over-grip series is offered in the coverage range from Ø0.5mm - 7.2mm diameter (Ø0.020" - 0.283").

Microconic™ Overgrip Collet. A = Grip Ø, B = Largest Part Ø, G = Grip Land Width

Over-grip collets, also referred to as over-the-shoulder collets, are used in a pick-off /sub-spindle when it is required to clear a shoulder and grip on a smaller diameter beyond the larger diameter.

The Drill blank pictured at the left is a good example of this kind part.

Extra spread is required to open the collet wide enough to go over the larger diameter. The grip diameter (A), the width of the grip land (B) and the largest part diameter to reach over (G) are required to choose the off-the-shelf over-grip collet for your specific part.

Microconic™ Over-grip collets are a great way to expand your CNC machine's capability and reduce cycle time.

The Problem
Generally, pick-off collets grip short part lengths that only occupy the front section of the bore. All of the clamping force is on the collet angle, which is a considerable distance from the part being held. As a result the collet begins to collapse under the angle.

At that point, the bore is no longer parallel and does not squarely grip the part. This usually results in the parts running eccentric and slipping in the collet. At that point machine operators generally increase the clamping pressure in reaction to the runout. This eventually results in the premature failure of the collet.

Another problem that is peculiar to pick-off collets is that they are sometimes closed without a part in place. Having no internal resistance puts undue strain on the collet walls, which can contribute to premature collet failure.

Microconic Over-grip collet opens over bone screw thread to hold the workpiece on the shoulder.

Collet Workholding Concentricity from 0.0001" to 0.00015"

Article originally appeared in Cutting Tool Engineering March 2014 / Volume 66 / Issue 3

In the world of micromachining, precision is relative—the smaller the work, the greater the need for accuracy in all aspects of the process. End users must optimize the entire micromanufacturing system to be efficient, competitive and successful.

Traditional techniques for achieving precision may work well for macro-scale parts, but can be subtly awkward or downright clumsy when applied to smaller work. Workholding is a classic example of this, noted Matt Saccomanno, a principal who handles product design, engineering and R&D for Masa Tool Inc.

He added that a collet is often the best workholding method because it firmly grips the workpiece and is highly accurate in a production setting.

However, the collet system installed by the machine builder accommodates the largest workpiece the machine was designed for, such as a Swiss-style machine with a 20mm capacity.

Microconic workholding system consists of (clockwise, starting at 12 o’clock) a cartridge, collet, hex key wrench and collet wrench with graduations for adjusting the collet closure.

The Microconic system can be installed in the subspindle of a Swiss-style CNC lathe.

Although collets for smaller bores to hold smaller workpieces are available, the rest of the system (collet body, spindle nose and closing mechanism) is sized for 20mm, creating problems when chucking smaller parts, according to Saccomanno.

Therefore, Masa Tool developed the Microconic collet system specifically for holding workpieces from 10mm (0.39 ") to 0.75mm (0.03 ") in any machine that has a collet-type chuck. The system consists of two major components: the cartridge, which transforms the work spindle for miniature workholding, and the “right-sized” collet, which fits in the cartridge.

Microconic System for Micromachining Offers Precise Control

Lori Beckman , Managing Editor
Originally titled 'Precision Collet Device for Micromachining Offers Precise Control'

The system provides precise control of collet closure despite the force a machine’s closure system exerts. Delicate parts can be held firmly and precisely without damage.

The cartridge provides extended nose capabilities, but remains solid and rigid. The cartridge nose is designed with a small diameter, so tooling and coolant have easy access to the workpeice.

This eliminates the need for extended nose collets and greatly decreases concentricity runout, the company says.

Microconic collets (UM10’s) are designed for high precision, small workpeices. Hardened blanks are available for delivery within hours of ordering.

The collets are available in size increments of 0.050 mm (0.001”), and diameter sizes start at 1 mm (0.039”) and go up to a maximum of 10 mm (0.393”).

Microconic system components

Masa Tool Inc. has created a precision collet device for the micromachining industry. The “Microconic System” is a miniaturized collet system that consists of two major components: the Microconic “cartridge” that fits directly into Swiss spindles like a collet and the Microconic collet that is a “right size” style collet. This chucking method is available for both draw-type (5C) and push-type or “dead length” systems (TF25), used on the subspindle of Swiss CNC lathes.

The Microconic grind provides extreme accuracy, high gripping force and tolerance for workpiece size differential, the company says. Each finger of the collet has a separate conical surface that acts to apply the gripping force with accuracy.

Workholding: Hold Small Round Parts

When you need to make small parts, the size range of the 5C collet is where the best variety and value exist in machine tools and accessories. You don't want to sink capital into expensive, specialized machinery that will run nothing but small parts. But a 5C collet is pretty big compared to your 1/8-inch diameter part.

An adapter is available, however, that renders a common 5C machine tool capable of handling very small diameter parts. The new small parts adapter, manufactured by Masa Machine Tool Accessories, Oceanside, California, fits in any machine's 5C collet closer, just like a standard 5C collet, without any modifications or special mounting procedures.

With the adapter, any machine with a 5C collet closer can chuck workpieces in the range of 0.010 to 0.375-inch diameter (0.25 to 10 mm). Yes, I truly mean that a common CNC turret lathe with one-inch shank tooling and a brutally powerful hydraulic 5C collet closer can easily chuck fragile 0.010-inch diameter workpieces effectively and repeatably, without damage. Of course, I don't recommend using a machine like that to make a part that small. However, this shows the level of control that the adapter provides.
