 At Masa Tool no machine is put into production without a thorough calibration and extensive customization. Here our cofounder and master of precision Dragan Marjanovic personally inspects a newly reconditioned grinding machine. 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.

High precision long nose collet system for sliding-head Swiss-type CNC lathe/turning centers. Opens 4mm larger than clamping diameter! Super accurate, super rigid. PMTS 2019: Masa Tool’s F37M10 cartridge is said to replace the standard TF37 collet in a users CNC spindle. #PMTS  The F37M10 Microconic cartridge from Masa Tool is a micro-workholding system for use in high precision, small diameter CNC turning applications. Masa Tool’s F37M10 cartridge is said to replace the standard TF37 collet in a users CNC spindle. This enables the use of the company’s Microconic collets to achieve concentricity within 5 microns (0.0002"), according to the company. The cartridge is a micro-workholding system for use in high precision, small diameter CNC turning applications. This cartridge is compatible with spindles that accept DIN 1536E, Meister Swiss 563, Schaublin F37 (76-740), Southwick and Meister TF37, KEB (MasWerks) MC37 and Hardinge TF37 / 4619 collets. The company’s cartridge and collet assembly is designed to vector the chucking force directly over the holding surface. This means the chucking force is reduced while at the same time the holding power is increased. This is said to open up the possibility of moving part operations to the sub-spindle and reducing cycle time. Also, the cycle time is commonly reduced by 20-40 percent.

 OCEANSIDE, CA - Masa Tool has just released the newest product in the Microconic line of cartridges for swiss machine workholding. The NEW push type F37M10 Cartridge replaces the standard TF37 collet in your CNC spindle. This enables you to use our Microconic collets to achieve concentricity guaranteed to be within 5µm (0.0002") in production use. The F37M10 Cartridge is 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. Compatible with spindles that accept DIN 1536E, Meister Swiss 563, Schaublin F37 (76-740), Southwick & Meister TF37, KEB (MasWerks) MC37, Hardinge TF37 / 4619 collets. Masa’s Cartridge and Collet assembly is designed to vector the chucking force directly over the holding surface. 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 moving part operations to the sub-spindle and dramatically reducing cycle time. 20% ~ 40% cycle time reduction is commonly achieved. This new cartridge will be demonstrated for the first time at IMTS 2018 in the West Building, Level 3 & Annex - Tooling & Workholding Systems - 432232
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.
But, in some cases, with longer parts, the land width "B" needs to be longer to support the workpiece properly. Masa's new T-type collet provides the solution for longer workpiecesTypically 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.
Microconic T-Type Over-grip Collet features
If you've tried other companies overgrip collets with poor results, Microconic over-grip collets will allow you to do things you might have thought impossible!
