Machinable Collet Clamps Hold Any Shape!
Custom-fit for small, thin, complex, and irregularly shaped workpieces — both OD and ID.
Machinable Collet Clamps hold both external and internal shapes of workpieces with a single tightening.
Ideal for machining small, thin, complex, and irregularly shaped parts on machining centers or turning lathes.
The collet is divided into up to 10 sections, distributing clamping force evenly along the outer or inner contour to prevent deformation.
Its compact body allows for multiple clamps to be mounted on a single fixture plate.
This simple workholding solution helps reduce time and effort in fixture design.

Feature
Machinable Jaw
Any shape can be clamped by machining the jaw to fit the contour of external or internal workpieces.
Divided Collet Jaw for Uniform, Secure Clamping
A multi-segment collet mechanism applies uniform force along the contour, ensuring secure and deformation-free clamping.
Quick and Simple Operation
Clamping is achieved with a single tightening or by supplying compressed air—no complex setup required.
Compact Design
Its compact body enables multiple clamps to be installed in tight spaces, maximizing fixture efficiency.
Additional Feature
Changeable Jaw for Flexible Workholding
Changing the jaw allows quick adaptation to different workpiece shapes, making dedicated fixturing faster and more cost-effective.
Versatile Clamping for Turning Applications
Complex or irregularly shaped parts that are difficult to hold with a standard chuck can be securely clamped using machinable jaws—ideal for turning operations.
Application Example
Clamping Low-Profile Workpieces
Thin parts can be securely held using internal clamping jaws that distribute force evenly through 8 jaw sections.
Proper torque control ensures optimal performance and prevents deformation of delicate parts.
Temporary Fixturing on Vises
The clamp can be quickly mounted onto an existing vise using a fixture plate — ideal for short-run or trial jobs.
Case Study
Multi-Part Clamping for 5-Axis Machining
KINKI KOGYO Inc., a manufacturer of hydraulic cylinder components and other precision parts, implemented IMAO's Machinable Collet Clamps to optimize their 5-axis machining operations.
Before
The company used several types of vises or dedicated fixtures to hold one part at a time, requiring multiple setups and high fixture costs.
This limited machine utilization, especially during unmanned night-time operation.
After
By adopting Form Holding Clamps, they were able to clamp four workpieces simultaneously on one fixture plate.
This significantly reduced setup time and cost, and increased machining efficiency—especially during overnight runs.
