Innovation “four-wire rail”patent structure

Main Features

1. Low overturning torque

The E-type adopts a four wire rail bearing structure, which is a "stable trapezoidal structure" formed by one driving center and one pulling center coplanar with two linear rails. This structure is highly symmetrical in the direction of force, eliminating most of the "pulling overturning moment" caused by the structure of the traditional lathe. Invention Patent No. :ZL 2020 10920618. 5.

2. Long lifespan and high stability

Large steel ball, large diameter, imported heavy-duty ball screw pair, high-precision, high rigidity brand heavy-duty roller linear guide.

3. Precise control, high precision

Servo drive+screw drive, reasonable force structure, impeccable cutting accuracy.

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".
