Swiss Machine Workholding Cartridges

11/14/2018

0 Comments

 
The push-type F201M10 micro-workholding cartridge system replaces F20-201 cartridges allowing the user of Microconic collets to achieve concentricity within 5µm (0.0002") in production use.

For use in high precision, small diameter CNC turning applications, it enables users to move more work to the sub-spindle for reduced cycle time.

The F201M10 cartridge is compatible with spindles that accept F20-201 collets including DIN 136E, Meister Swiss 136E, Schaublin F20 (76-201), Southwick & Meister F20-201, KEB (MasWerks) MC20-201, and Hardinge F20-201/4709 collets.

Masa Tool’s Microconic push-type F201M10 cartridge pairs with its Microconic collets
for concentricity within 5 microns (0.0002") in production use

Masa Tool’s Microconic push-type F201M10 cartridge pairs with its Microconic collets for concentricity said to be within 5 microns (0.0002") in production use. The cartridge is a micro-workholding system for use in high-precision, small-diameter CNC turning applications. The cartridge is compatible with spindles that accept F20-201 collets.
IMTS2018-pr-masatool-f201m10 microconiMasa Tool's Microconic F201M10 cartridge on display at IMTS 2018.
The cartridge and accompanying collet are designed to vector the chucking force directly over the holding surface, reducing the chucking force while also increasing the holding power. This reduces chucking damage on the workpiece and reduces cycle times by 20 to 40 percent, the company says. 

The cartridge’s solid extended nose enables access for tooling and coolant with minimal overhang. Its core diameter is a single-piece construction that is designed to maintain 5 microns (0.002") concentricity at the extended nose tip. Used with the company’s Micrograd wrench, the cartridge features micrometer dial control of collet clamping pressure regardless of the machine’s hydraulic or pneumatic collet closing force. The cartridge is suited for small-diameter parts ranging from 0.22 mm (0.008") to 10 mm (0.3934") in diameter.

"Micro-movement" of the workpiece is reduced, resulting in a longer tool life, better finishes, fewer chatter problems, and less damage to the workpiece. The cartridge eliminates secondary operations, saves time and enables operations to be done in the subspindle. Broaching, milling, saw cutting/slotting, turning, boring and drilling can be machined in the subspindle.

OCEANSIDE, CA - Masa Tool has just released the newest product in the Microconic line of cartridges for swiss machine workholding. The NEW push type F201M10 Cartridge replaces the Tornos F20-201 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 F201M10 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.

​The F201M10 Cartridge  is compatible with spindles that accept F20-201 collets including  DIN 136E,  Meister Swiss 136E, Schaublin F20 (76-201),  Southwick & Meister F20-201, KEB (MasWerks) MC20-201,  Hardinge F20-201 / 4709 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.​
F201M10 Cartridge 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 machines hydraulic or pneumatic collet closing force with the use of our Micrograd™ Wrench. Ideally suited for small diameter part size range from .2mm/.008" to 10mm/.3934" diameter
  • 2-days shipping on all cartridges and collets​.

​Masa Expands Offering of Microconic Over-Grip Collets with New Long-Land T-type Series.

2/13/2018

0 Comments

 
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.
The Microconic  over-grip collets provide more work holding and programming options than previously available. It enables you to move operations from the main spindle to the sub-spindle. This balances the work being performed between the main and sub time which can dramatically reduce cycle time.  

​The land width on the W-type over-grip collet, pictured at the right,  is approximately 1 X Diameter of the workpiece. 
Micorconic W-Type Overgrip Collet
The Microconic W-type over-grip collet can swallow up to 4mm over the held diameter
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 workpieces

Typically 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.
​It may also be necessary with very wide-pitched threads, such as on bone screws, where a long land in the collet allows spanning several thread pitches instead of just one or two. This same spanning issue can occur with parts that have wide grooves.

The  new "T-type" over-grip collet,  has a longer gripping surface than our original W-type: Typically 2 - 3 times the diameter of the workpiece.

​For extra long parts, the T-type collet provides the opening needed for the larger head to pass through the collet, so it can be pushed through the back end of the spindle for ejection when required.
Microconic T Type Overgrip 2-3X Land width
The Microconic T-type over-grip collet provides 2 -3 times the land width "B" of the W-type over-grip collet to support longer parts.

Microconic T-Type Over-grip Collet features

  • Standard gripping land length is 2x - 3x diameter. (vs. about 1x diameter with W-type)
  • Available from Ø1.55 - 7.2mm (Ø.061" - .283"). 
  • Opens 3.5mm diameter (.138") larger than the clamping diameter. (vs. 4mm larger with W-type).
  • Every size available to ship within 2 days of order.
  • Same Microconic accuracy and rigidity.
Typical uses are generally for over-gripping of longer parts:
  • Bone screws with wide-pitch threads
  • Orthopedic surgical drills and taps
  • Long shafts with flange
  • Long, thin walled tubular parts
  • Long plastic parts
