Colchester Broaching Units

Broaching units cut internal keyways, hexagons and squares on the lathe, removing the second operation on a broaching press or a slotting machine. Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan, builds them to mount on Colchester turrets.

Designed for Integrated Gear and Keyway Machining

Gear and keyway machining often require additional specialized equipment or secondary setups, which increase processing time and the risk of positioning errors. We provide a comprehensive integrated broaching solution, enabling customers to complete internal gears, external gears, and keyway machining directly on their Colchester multitasking turning-milling centers, significantly boosting production line integration efficiency.

Turnkey Integration & Planning Service: Simply provide your machining drawings, and we will handle everything—from broaching unit selection and dedicated toolholder design to custom-shaped insert planning. We deliver a one-stop, tailored configuration to reduce development risks and testing costs for your Colchester equipment.

High-Precision Reciprocating Mechanism:

Featuring a precision reciprocating drive design to ensure dimensional consistency and stable forming quality. Suitable for:

Internal Gear Machining

External Gear Machining

Keyway Broaching

Special Tooth Profile Forming

Adjustable Stroke Range (25 – 65 mm): Available in multiple stroke specifications to meet various machining depth requirements, making it adaptable to diverse workpiece designs.

Enhanced Process Integration Efficiency: Reduces the need for secondary setups, lowers outsourcing costs, improves dimensional consistency, and shortens overall cycle times.

Maximize Machine Productivity: Completing broaching operations on a single machine effectively increases equipment utilization (OEE) and overall production capacity for Colchester users.

Getting the right holder

The machine model alone does not decide the holder. The same model can leave the factory with different turrets — station count, model suffix and key arrangement all change the mounting. Tell us the machine, the turret and the operation and we confirm the mounting before quoting.

Already using another brand? Send the drawing or the article number of the holder you run today and Mongtec will convert it to an equivalent Mongtec holder — same mounting, same reach, same output.
