IMTS 2016 was Incredible!

9/29/2016

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!

Avinger Review of Microconic TF25 Collet System

5/18/2016

0 Comments

Avinger Inc., based in Redwood City, California, designs, develops and manufactures precision medial device technology with the goal of helping patients keep their legs. Recently they began testing the Micoconic system on their Citizen L20 (7M8) Swiss Screw Machine using a Utilis 3000 series cutoff holder and an 1/5mm X 10mm insert. The bar stock was .225" OD round.

They where kind enough to share their test results with us.

Masa Tool Introduces the Microconic™ Over-grip Collet

5/20/2015

2 Comments

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").

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.

The Solution

Over-grip collets from Ø0.5mm - 7.2mm diameter (Ø0.020" - 0.283").
Opens up to 4mm (0.157") diameter larger than the clamping diameter. Some restrictions apply to larger sizes approaching the 7.2mm (0.283") max diameter
Grips with the same industry-best rigidity and accuracy as our standard collets.
Compatible with all Microconic M10 cartridges: F20M10, F25M10, 5CM10 & 16CM10.
Fatigue tested design to over 250,000 full-load cycles.
Microject™ Brass ejection guide sleeve blank is included with each Microconic™ over-grip collet.
All sizes available to ship in 2 days.
Reduce part cycle time by moving operations to the sub spindle that you might currently be performing in the main spindle.
