F37M10 Cartridge

The 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, E1536,  Southwick & Meister TF37, KEB (MasWerks) MC37,  Hardinge TF37 / 4619 collets.

Holding Power:
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.

F37M10 Features

  • Solid extended nose, giving superior rigidity, and access for tooling and coolant with minimal overhang.
  • The cartridge's core diameter is a single piece construction that will maintain 5 µm/.0002" concentricity at the extended nose tip.
  • Micrometer dial control of collet clamping pressure regardless of the machines hydraulic or pneumatic collet closing force with the use of our Micrograd™ Wrench. See below for more details.
  • Ideally suited for small diameter part size range from .2mm/.008" to 10mm/.3934" diameter
  • All products​ ship within 2-days.
Chucking force directly over the chucking surface
  • Reduces the need for excessive force to hold the work piece. 
  • Significantly reduces chucking damage on the work piece. 
  • Thin wall chucking is now possible without crushing the part.
Reduces "micro-movement" of the workpiece which means
  • Longer tool life
  • Better finishes
  • Chatter problems are less likely
  • Less damage to the work-piece
More operations can be done in the sub-spindle
  • Eliminate secondary operations.
  • Reduce labor/downtime/changeover/set-up costs significantly.
  • Saves time due to overlapping machining in the main spindle.
Part features that were not possible to machine before are now possible in the subspindle.
  • Broaching
  • Milling
  • Saw Cutting/Slotting
  • Turning
  • Boring
  • Drilling

Collets for the F37M10 Cartridge

Micrograd™ Dial Wrench

 Set ups are quicker and more repeatable with the Microconic™ system.Each cartridge includes a Micrograd Dial Wrench. You can document the micrometer-like 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". 
CW10 - Micrograd™ Wrench 10mm
Our CW10 Micrograd™ Dial Wrench is included with the purchase our F37M10 Microconic Cartridges.

The Micrograd™ 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"
