LJMA-160 is a CNC busbar chamfering and surface milling machine. It removes the burr left by shearing and prepares contact faces for bolted joints. We recommend it to switchgear builders who need to control contact resistance and contact face quality. Delivery includes the CE declaration, installation, operator training and a 12-month warranty.
Test conditions: Copper Cu-ETP (99.9% Cu), busbar 10 x 100 mm, 2 x 45 degree chamfer, workshop temperature 20 °C, batch of 150 pieces.
Measured values: Working width 200 mm, machined surface roughness Ra 1.6 µm, feed rate 3 m/min, chamfer angle deviation ±0.3°, cycle 25 s per piece.
Comparison baseline: Baseline: manual grinding, roughness Ra 6.3 µm, cycle 15 min per piece, quality scatter between operators.
LJMA-160 CNC Copper Busbar Milling Chamfering Machine shearing machine

Main function
The main function of CNC busbar milling machine is milling (round arc) of copper or aluminum busbars.
Main features
It is mainly used for milling corner of busbars with thickness of 6-16mm,width of 30-160mm and length of 260-6000mm.
Adopt the gantry mechanical structure, the design is simple,the operation is stable,the structure is rigid.
the installation with a six-position straight-line cutting tool,which can automatically replace the cutting tool according to the width of the busbar.
Automatic accumulative working hours function,and cannot clear zero.Together with the function of production counting and can clean zero at the same time.
Adopt international standard BT40 shank,easy changing cutting tool,good steel and high precision.
Adopt two axe control system,simple operation and convenient maintenance.
Can simulate operation and manual programme online.
