At IMTS 2024, Speedgrip Chuck demonstrated its leadership in advancing workholding technology with the launch of four new products designed to streamline operations and boost productivity. Known for its legacy in secondary operation chucks, mandrels and pallets, the company has expanded its portfolio with quickchange and intelligent workholding solutions aimed at meeting the demands of modern manufacturing.
Speedgrip Chuck’s latest offerings reflect its focus on enhancing efficiency and adaptability. With a history rooted in delivering high-performance solutions, the company has ventured into new territories, such as threejaw chucks, while integrating advanced automation features. These innovations are set to address the evolving needs of manufacturers, particularly in reducing downtime and enabling faster transitions between jobs.
Quick-Change Three-Jaw Chuck
One of Speedgrip’s innovations is its quickchange three-jaw chuck, which supports multiple standard jaw types, including Kitagawa serrated and tongue-and-groove styles. The chuck features dual base jaws, allowing operators to adjust diameters offline while the machine is running. This capability significantly reduces setup times and minimizes machine downtime.
The chuck also accommodates mono-block jaws, which eliminate interference from mounting holes, enabling closer applications to the chuck face. Additionally, the chuck’s lever- style design includes counterweights that increase clamping force under centrifugal rotation, ensuring reliable performance even at high speeds.
NDS Mandrel (No Draw Screw)
Speedgrip’s NDS mandrel eliminates the need for traditional front draw bolts, a common wear item. Using a bayonet-style connection, the mandrel ensures precise ID clamping while minimizing maintenance requirements. Its machinable work stop is prepped for air sensing, providing enhanced accuracy and reducing setup complexity.
QCR (Quick Change Receiver)
The Quick Change Receiver offers flexibility by enabling complete spindle face changeovers. With cam-lock mechanisms, operators can easily switch between workholding solutions such as collet chucks, face drivers and mandrels. This versatility makes it a valuable tool for operations requiring frequent transitions.
Contactless Stroke Controller
Addressing precision and safety, the contactless stroke controller replaces traditional proximity switches with sensors capable of measuring down to two decimal places. This innovation allows for multiple clamp positions and ensures that parts are accurately secured with “poke-yoke” functionality — a go/no-go system that verifies correct setup before operation.
Speedgrip’s innovations exemplify the company’s commitment to reducing lead times and improving overall efficiency. By incorporating quick-change systems and intelligent controls, these solutions enable manufacturers to optimize their workflows, regardless of production volume or complexity.
The scalability of these products also ensures that they meet the diverse needs of the industry, from high-volume operations to precision machining for specialized applications.

Related Glossary Terms
- chuck
chuck
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- collet
collet
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
- inner diameter ( ID)
inner diameter ( ID)
Dimension that defines the inside diameter of a cavity or hole. See OD, outer diameter.
- mandrel
mandrel
Workholder for turning that fits inside hollow workpieces. Types available include expanding, pin and threaded.
- precision machining ( precision measurement)
precision machining ( precision measurement)
Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.
