5CM10 Cartridge

masa-tool-microconic-5CM10 cartridge

The pull-type 5C Microconic Cartridge replaces the standard 5C 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 5C 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.

5C collets are some of the most widely used and versatile clamping methods used in metal cutting lathes and mills today but have never been able to provide the accuracy and rigidity often needed for small diameter parts. Until now…

Development of the 5C cartridge dates back to the late 1990s but this newly introduced version is manufactured using our unique “Microconic” production method that provides more accuracy and rigidity than was possible with any other “off-the-shelf” rotating clamping system.

The “Microconic System” is a miniaturized collet system that consists of two major components: the Microconic™ “cartridge” that fits directly into 5C spindles and the Microconic collets that is a “right-size” style collet.
If you have any secondary gang-tool or turret lathes with a 5C collet system you will LOVE the Microconic 5CM10 cartridge. Better tool clearance with the extended nose. Micrometer control of collet closure regardless of hydraulic/pneumatic/manual collet closing mechanism of the machine. Unbeatable concentricity.

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.

5CM10 Features

  • Solid extended nose, giving superior 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 machine’s 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
  • 2-days shipping on all cartridges and collets.

Masa Tool introduced 5C Microconic cartridge in 2016. It maintains 5 µm concentricity and is now available for machining centers, CNC lathes, CNC mills, gang-tool lathes, like Omniturn, CNC mill/turn, like Nakamura, Miyano, Mori-Seiki, and even rotary indexers as well as tool and cutter grinders!

Collets for the 5CM10 Cartridge

Micrograd Face Dial Wrench

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”.

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″

5CM10-E – Inch version graduations on the MicroGrad dial wrench included with each cartridge.

5CM10-M – Metric version graduations on the MicroGrad dial wrench included with each cartridge.

Microconic system ships within 2 days of order.
