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!
NEW Masa Tool offers a Comprehensive Range of Microguide EGS™ Ejection Guide Sleeves in Different Materials
The standard Microguide EGS is made of brass. Masa Tool has expanded the standard offer of Microguide EGS to include a selection of both Plastic and Stainless Steel versions.
A critical aspect to using over-grip collets is to make sure the part is ejected reliably when it is completed being machined. Due to the wide opening of the over-grip collets, parts can get jammed in the collet slot. As a result, the collet will be damaged or break when it is closed.
Every Microconic over-grip collet is supplied with a blank Microguide EGS ejection guide sleeve that you can drill to size to fit your specific part to enable the finished part to be ejected consistently without damage to the over-grip collet. The EGS is meant to be drilled through with a loose-fitting hole that will support and help guide the workpiece as it is ejected from the collet. Users can customize the Microguide EGS to match their specific workpiece and method of ejection.

They are our part number EGS10-12.

It was the cover story entitled: "Micro-Precision Machining" by Elizabeth Modic
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.
