MAIN FEATURES
1.Low overturning moment

Model E adopts a four-linear-rail load-bearing structure,where one driving center and one broaching center form a "stable trapezoidal structure"together with Two linear rails on the same plane.This design ensures high symmetry in the force-bearing direction,eliminating most of the"broaching overturning moment"caused by traditional broaching machine structures.Patent No.:ZL 202010920618.5.
2.Long lifespan and high stability

Large steel balls,large diameter,large lead imported heavy-duty ball screw assemblies;high-precision,high-rigidity imported heavy-duty roller linear guides.
3.80m/min,precise control,high precision

High-Response Servo Drive+Large-Lead Screw Drive,ensuring flawless broaching precision.Achieves a maximum broaching speed of 80m/min,with seamless switching between soft and hard broaching.
4.Flexible and versatile spatial layout
The equipment can be customized with layout according to customer requirements,flexible and versatile,to achieve various forms of automation requirements.
5.One click intelligent control

Intelligent CNC system+embedded program+highly secondary development,parameter filling and use,zero programming operation,safe and efficient.
6.Convenient and easy to operate

Quick change of tooling,automatic positioning,and practical operation on the machine by the operator with "zero foundation".
