Main Application 
The MJK743 door‑frame sawing and milling production line comprises a continuous workflow for cutting door frames, drilling assembly holes, routing hinge mortises, and machining latch‑strike slots. The door frames can be cut at 90° and 45° angles, with holes drilled at both angles. Each machine is a CNC‑controlled, automated processing unit capable of producing door frames in a wide variety of styles according to design specifications.
MJK743 door frame production line can make the door frame cutting, assembly door holes,slotting and hinge holes.90° and 45° cutting for door frame, 90° and 45° driling for holes.
CNC controlled, It can process various types of door frames according to requirements.
Main Features
It employs the German BECKHOFF motion control system, enabling rapid programming and customized machining strategies, and supports personalized design of machined shapes. Equipped with servo control featuring absolute encoders, it delivers high positioning accuracy and automatic homing to the zero position.
The door frame is mitered at both ends, and two hinge mortises are machined simultaneously. The end miters can be either 90° or 45°, or both 45°. While cutting, one of the three hinge mortises is also machined, thereby enhancing production efficiency.
The Germany BECKHOFF control system is used to quickly program the processing plan and personalized design supported.
Absolute encoder servo motor and ball screw used in the independent NC,which providing the precisely milling and shaping.
Door frame two ends can be cut and mill at the same time, as well as the two hinge holes.Both ends can be 90° and 45° or two of the 45° . Machining one of the holes while miling, more efficient.
