Well-designed clamping solutions for micro-manufacturing The new EROWA CMT Compact Micro Tooling adds yet another innovation to the successful EROWA clamping system portfolio and takes high-precision micro-manufacturing to a whole new level.

Specifically developed for sustainably energy-efficient micro-machining, the CMT clamping system combines uncompromising precision, superior quality, and maximum efficiency in the smallest spaces – from watchmaking and jewelry to medical technology and microtechnology.

EROWA CMT COMPACT MICRO TOOLING

Low-profile clamping The CMT’s spigot-free clamping mechanism minimizes overall system height while maximizing workpiece capacity – ideal for machines with limited machining space.

The chuck with a center pass-through is suitable for applications that require the chuck to function with a plunger.

The plunger can be used to actuate compatible collets on the chuck. The optional reclamping feature allows the clamping force to be increased, enabling higher plunger forces.

The chuck without a center pass-through is suitable for all applications, from milling, turning, and grinding to measuring, EDM, and WEDM.

An option seal can be mounted on the chuck to protect against chips and other debris.

THE BENEFITS Tooling System

Robotics

It doesn‘t get much more compact than this: The CMT chuck fits easily on a standard business card.

• Ultra flat and compact tooling system • For holding workpieces, collets, and fixtures • Ideal for machining workpieces up to 50 x 50 x 50 mm • High repeatability • Optional reclamping function for increased clamping force • Versatile for milling, turning, grinding, EDM, and WEDM • Suitable for manual and automated applications

Maximum precision in the smallest of spaces The CMT clamping system features a combination of spring tension and integrated self-locking to securely hold the pallet. A central pass-through allows the use of a plunger to activate clamping elements mounted on the pallet, such as collet chucks.

For more demanding applications, the clamping force can be further increased through targeted reclamping, which in turn allows for higher actuation forces to be applied to the plunger. Reference supports with integrated pneumatic passages also enable direct control of pneumatic clamping elements on the pallet.

The CMT combines a high-precision interface with an ultra-compact design and maximum functionality.

Mounting hole for indexing pin

With a gripper contour for automated handling

The support feet ensure precise positioning

Centering plate for precise positioning and alignment of the pallet in the chuck

Integrated optional air passages enable direct control of pneumatic clamping elements on the pallet

Depending on the chuck model, a central pass-through enables plunger-actuated pallets with collets.

Ceramic balls for maximum performance Indexing pin for orienting pallets

Self-locking clamping mechanism for reliable clamping without air pressure

Ground Z-support surfaces with holes for cleaning and presence detection, as well as an optional air passage

The centering prisms provide positioning of the pallets with µm precision

Quick and precise tool changes with CMT collets The CMT collets allow workpieces such as watch cases to be clamped securely and precisely for machining. The pallet is positioned and precisely clamped in the CMT chuck within seconds.

The collets ensure secure, defined, and gentle workpiece clamping and provides optimal accessibility during machining. Its defined interface ensures high repeatability, minimizes setup times, and enables efficient, consistent machining of different work-pieces – for maximum productivity and process reliability.
