Chuck Diagram

Warning: While the static clamping force of all three-jaw chucks is a function of the machine’s hydraulic actuator (piston surface area, input pressure, etc.), it is essential to understand that the dynamic clamping force acting on a workpiece is affected by additional factors such as rpm and top jaw weight. This graph represents the maximum dynamic clamping force of all Royal MTC™ chuck models throughout the stated rpm range.

Be sure to understand the relationship between input pressure and drawtube axial force for your machine’s specific hydraulic actuator and ensure that all relevant parameters are sufficient to keep workpieces safely clamped. If you have any questions or concerns regarding the safe use of this product, please contact a Royal Products applications engineer at 1-800-645-4174 before use.

In addition to the safety considerations regarding actuator force and drawtube stroke, Royal may also require some specific dimensional information for your lathe to ensure that we supply the correct backplate and drawtube connector.

We maintain an extensive machine tool database populated with thousands of actuator and drawtube specs, but sometimes changes/substitutions are made to the machine that we aren’t aware of. For safety purposes and to ensure a hassle-free installation experience, the information requested below may need to be supplied with your MTC™ order. If you have any questions, please contact a Royal Products applications engineer at 1-800-645-4174.

The Royal MTC™ is a Revolutionary 3-Jaw Chuck, Collet Chuck,
and I.D. Workholding System All-in-One

Royal MTC™ Advantages

  • The Royal MTC™ Multi-Tasking Chuck is the only chuck you’ll ever need for your CNC lathes.
  • This is a true all-in-one workholding device designed to handle large diameter parts, small diameter parts, and parts suited for I.D. gripping.
  • The key to this revolutionary all-in-one design is the quick-change center hubs – there is no need to ever remove the chuck body from the lathe spindle.
  • The center hubs are hardened, precision ground, and TiN coated for exceptional accuracy and wear resistance.
  • Extreme rigidity is achieved through a common-sense design based upon a 3-jaw chuck with collet and I.D. capabilities – not a collet chuck with a heavy jaw-chuck hanging off the front end.
  • Faster and much more cost-effective than changing out various chucks or using a “quick-change” adapter plate system that requires a crane and staging cart.
  • High accuracy – jaw repeatability is 0.0002” – 0.0003”, and collet hub taper is guaranteed to be with 0.0003” TIR.
  • All chuck bodies are relief milled to optimize tool clearance and reduce rotational mass.
  • Available in 8”, 10”, 12”, and 15” sizes
  • All Royal MTC™ Multi-Tasking Chucks include the following:
  • A 3-Jaw chuck featuring industry standard 60°x1.5mm base jaws to accept a wide array of top jaws.
  • A Quick-Grip™ center hub hardened and precision ground to accept Royal QG Collets.
  • A thru-hole center hub to accommodate long-parts when using as a jaw chuck.
  • A center cap to block chips from entering the drawtube when using the jaw chuck for slug work.
  • A removeable internal workstop for use with both jaws and collets.
  • A grease gun and tube of chuck grease.
  • A custom-machined drawtube connector for hassle-free installation.
  • Two-jaw chucks, face drivers, Morse Taper adapters, and alternative collet adapters (5C, 3J, etc.) are also available as special order.
  • The center hub for I.D. work is sold separately and is compatible with all Royal I.D. mandrels, stops, and sleeves.

Setup Times Slashed
Change from jaw chuck to collet chuck to I.D. mandrel in minutes without ever removing the chuck from the spindle

Extreme Rigidity
Much more stable than other systems because MTC™ is a true jaw-chuck with both collet and I.D. capabilities – not a collet chuck with a heavy jaw chuck hanging off the front end.

High Accuracy
Jaw repeatability is 0.0002″ –0.0003″ and the QG collet hub is guaranteed to be within 0.0003″ TIR.

Great Tool Clearance
All chuck bodies are relief milled for optimized tool clearance and reduced rotational mass.

Ingenious Patent-Pending Design
Simply change out the hardened and ground TiN coated center hubs as applications require – chuck body always remains mounted to the lathe spindle.

Standard Top Tooling
All Royal MTC™ chucks incorporate base jaw serrations of 60° x 1.5mm as standard. Alternative base jaws with inch serrations or quick-change configurations are available as specials.

Multiple Sizes
Royal stocks the MTC™ in 8″, 10″, 12″, and 15″ versions. Backplates are available to suit all standard spindle mounts.

Unmatched Flexibility
Run virtually any job on a single CNC lathe – modular design provides the ability to seamlessly integrate additional components (5C collet adapter, face driver, etc.) as needed.

Easy Single Part Number Ordering
