Special Fixtures are custom-designed workholding solutions engineered to accurately locate, support, and clamp components for machining, inspection, welding, or assembly. Developed specifically for component geometry, tolerances, machine type, and production volume, they improve accuracy, reduce cycle time, and ensure consistent quality in CNC, VMC/HMC, SPM, laser, and automated production environments.
Special Fixtures are custom-designed workholding solutions developed to locate, support, and clamp components accurately during machining, inspection, welding, or assembly. Unlike standard fixtures, special fixtures are engineered specifically for your component geometry, tolerance, machine, and production volume, ensuring higher accuracy, reduced cycle time, and consistent quality.
They are a critical part of process optimization for CNC lathes, VMC/HMC, SPMs, laser machines, and automated production lines.

A Hydraulic Hose / Pipe Swager – Crimping Chuck is a heavy-duty forming and clamping system used on hose crimping and swaging machines to permanently join hoses, pipes, fittings, and ferrules. It applies controlled, uniform 360° radial pressure to ensure accurate crimping, strong retention, and leak-free performance, making it ideal for high-pressure hydraulic applications, production lines, and service workshops.
A Multiple Stationary Expanding Collet Chuck – Hydraulic is a non-rotating internal workholding system that uses hydraulic expansion to clamp multiple hollow components simultaneously from the inside diameter. It provides uniform 360° expansion, distortion-free holding, and high concentricity, making it ideal for thin-wall pipes, bushes, sleeves, and tubular parts in CNC lathes, SPMs, and automated production lines.
VMC Fixtures are precision workholding systems designed for Vertical Machining Centers to accurately locate, clamp, and support components during milling, drilling, tapping, and boring operations. Available in manual or hydraulic configurations, they are engineered for high rigidity, repeatability, and productivity based on batch size, tolerance, and automation requirements.
A VMC Collet Chuck is a precision tool holder used on Vertical Machining Centers to clamp cutting tools such as end mills, drills, reamers, and taps using collets, typically ER series. It provides low runout, strong gripping force, and excellent balance, ensuring accurate machining, superior surface finish, and extended tool life.
A Drill Collet Chuck is a precision tool-holding device designed to securely clamp drills, reamers, taps, and small cutting tools with high concentricity and minimal runout. Compared to conventional drill chucks, it offers stronger grip, better balance, and higher accuracy, making it ideal for CNC and precision drilling applications.
Surgical Ortho Fixtures are high-precision, contamination-controlled workholding solutions designed for machining orthopedic implants, surgical instruments, and medical components. They provide micron-level accuracy, repeatability, and surface integrity, supporting complex geometries and biocompatible materials while meeting stringent medical industry and regulatory standards.
Surface Grinding Fixtures are specialized workholding devices used to accurately locate and clamp components during surface grinding operations. They ensure flatness, parallelism, squareness, and repeatability while minimizing vibration and distortion, making them ideal for achieving fine surface finishes and tight tolerances in toolroom and production grinding applications.
A Sliding Head ER Spindle is a high-precision spindle unit designed for sliding headstock (Swiss-type) CNC lathes to hold ER collets with excellent rigidity and accuracy. It enables stable, high-speed turning, drilling, and milling operations, delivering micron-level precision, superior surface finish, and vibration-free machining—especially for long, slender, and small-diameter components.
