Solving Pick Off Collet Problems by Masa Tool

10/4/2021

During the New England Tool Corp Oktoberfest Open House in September 2021, Matt Saccomanno, President of Masa Tool, presented a webinar "Solving Pick Off Collet Problems"

Matt talks about why traditional Pickoff Collets suck so bad: Micro-movement, Poor concentricity, Size is not available NOW and poor control of clamping pressure which leads to overall length variations and crushed parts.

No other collet system has permits you set clamping pressure for consistent clamping repeatability of 0.0002" TIR

Matt goes on to explain how the Microconic System solves all of the problems with traditional pickoff collet with a guaranteed 0002" TIR accuracy and ships everything from stock within two days of placing an order!

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!

The 2018-2019 catalog features NEW PRODUCTS including:

The NEW push type F37M10 Cartridge that replaces the standard TF37 collet in your CNC spindle and will be introduced at IMTS 2018.
The NEW Comprehensive Range of Microguide EGS™ Ejection Guide Sleeves in Different Materials. (July 2018)
The NEW push type F201 Cartridge that replaces the standard F20 collet. (April 2018)
The NEW Long-Land T-type Over-Grip Collets (February 2018)
The NEW Large Open V-Type Over-Grip Collets. (February 2018)

The Masa Microconic system consists of the cartridge, which fits into your machine like a standard collet, and the Microconic collets which fit into the cartridge.

The Microconic system provides:

Solid extended nose — extremely rigid
Micrometer-adjust control of collet closure — even the most fragile parts can be held safely and firmly.
Extreme accuracy — concentricity within 5μm (0.0002”) runout.
The Microconic cartridge can be used as a gauge to verify machine spindle accuracy.
Collets available from Ø0.2mm (0.008”) to 10mm (0.394”).
All collets hardened and precision ground to the highest quality standards.
Over-grip collets with performance unlike anything else! Open 4mm larger than the clamping diameter. Unmatched rigidity and concentricity. If you have tried other over-grip collets then you will be shocked at the difference — our Microconic over-grip collets are amazing.
The Microconic collets fit in any Microconic cartridge, no matter which machine.

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".

Our Micrograd™ Face Dial Wrench is included with the purchase of any Microconic Cartridges.

The Micrograd™ Face dial Wrench provides a method of precisely setting clamping pressure on both the Microconic collets and an Microconic overgrip collets .

It can be adjusted in metric increments of 0,02mm and imperial increments of .001"

Insert a gage pin of the appropriate diameter.
Tighten collet with Micrograd Collet wrench by 2 – 4 graduations to set initial clamping force.
For a firm grip on solid workpieces typically a closure of about .08mm (0.003”) is a good starting point.
Use the screwdriver allen wrench to lock the set screw on the cartridge in place.

Experience will soon teach the best settings, and they may vary significantly for different applications based on the force required, rigidity of workpiece, and machining operation being performed.

For a complete set of instructions please see our installation procedures for more details on how to set up and replicate your clamping pressure on every machine in your shop.
