Royal Quick-Grip™ Power-Block™ Collet Fixtures
- Royal Power-Block™ Collet Fixtures bring the full functionality of our Quick-Grip™ CNC Collet Chucks to your vertical and horizontal machining centers.
- These fixtures incorporate many of the same great features as our Quick-Grip™ CNC Collet Chucks, including ten-second collet changes and the use of parallel grip collets with a full 0.062″ clamping range (0.080″ for QG-100).
- A great alternative to traditional vises and fixtures – especially for long, thin parts, or those with asymmetrical external features.
- Units are designed to be actuated via hydraulic pressure, and may also be actuated pneumatically for lighter-duty applications.
- Engineered for use in both stationary and rotary-table applications.
Caution – not for use on lathes or grinders above 60 rpm! - Heavy-duty all steel construction with a large double-acting piston for high clamping force.
- Configured with both side and bottom ports for plumbing flexibility.
- Multiple units can be plumbed in series for single-source actuation.
- Mounting face is precision-ground for perpendicularity to centerline.
- Ideal for high-production vertical and horizontal milling applications.
Extremely Fast Collet Changes
Changing collets on a Royal Quick-Grip™ Power-Block™ takes just a few seconds. A unique hook and groove design for securing collets is used instead of traditional threads.
Flexible
The face of the Royal Power-Block™ is precision-ground and includes tapped holes, enabling the use of custom stops, locators, etc.
Heavy-Duty Construction
Body and piston are hardened to Rc 61-63 for maximum rigidity and durability.
Low Maintenance
Oversized evacuation slots on all four sides enable chips to be easily flushed clear on bore-thru applications.
Tool Clearance Optimized
Slim nose diameter offers better tool clearance compared to vises and other prismatic workholding devices.
Dual-Port Actuation
All units are equipped with ports on both the side and bottom surface of the fixture, offering actuation flexibility for both fixed and rotary table applications.
Precision Mounting
Internal bore and external OD are both precision-ground, offering flexibility while ensuring accurate, repeatable mounting to plates, tombstones, etc.
Wide Gripping Range
Royal Quick-Grip™ Collets have a 0.062″ gripping range (±0.031″), enabling them to accommodate undersized and oversized bar stock. This range is even larger for the QG-100 – 0.080″.
Extreme Grip Force
The gripping segments of Royal Quick-Grip™ collets always remain parallel to the workpiece over their full length, ensuring grip force is evenly distributed. This is a significant advantage for thin-walled parts that are susceptible to crushing.
Completely Sealed
Lubricated for life, these fixtures incorporate multiple O-ring seals to prevent chips and coolant from impacting piston movement.
Custom Collet Profiles
One of the greatest advantages of this workholding system is in Royal’s ability to supply custom collet profiles for odd-shaped second-op gripping.

Get More Out of Your Vertical, Horizontal, and 5-Axis Machining
- These multi-function fixtures enable you to use Royal QG collets, Royal I.D. mandrels/sleeves, and 5C collets in your 3, 4, and 5-axis applications.
- Manually actuated with a hex key (included).
- Many of the same great features as our QG Combo CNC Collet Chucks, including ten-second collet changes and parallel-grip collets with a full 0.062″ clamping range.
- Can be used in both stationary and rotary table applications.
Caution – not for use on lathes or grinders above 5 rpm! - Pullback design with an internally threaded backplate enables the use of a stop rod. Unit is supplied configured to accept Royal QG collets.
- For I.D. and 5C workholding, additional components are required (order separately).
How It Works
- Royal QG Power-Block™ Combo Fixtures directly accept Royal QG collets.
- For I.D. and 5C applications, a hardened and ground adapter (sold separately) is inserted and bolted to the fixture and engages with the piston via a bayonet arrangement.
- This adapter has a ground 75mm I.D. recess to accept Royal I.D. mandrels or our 5C collet nose.
