EA-4AS2540C is a cnc gantry milling machine with 4th axis. The spindle can rotate ±120° around Y axis. The name of 4^th axis here is B axis. So this gantry milling machine has four axes X, Y, Z and B. Compared with three axes machine, four axes has more possibility on machining. Besides the jobs of three axis gantry milling machine, it can machining block with cambered surface; also, it can machining complicated mould pattern which needs process on three sides. To clear one point here, three axes machine can machining some complicated also, but it can machining only one side one time, to finish the mould, you need stop machine and turn to right side two times. Undoubtedly, it is time costly.  

Applicable Materials

Styrofoam, Foam, PS, EPS, HDPE, Solid Wood, Epoxy Tooling board

Application

Mould pattern with cambered surface, complicated mould pattern which needs process on three sides and all mould jobs which can be worked on three axis cnc gantry milling machine.
 

Main Features

1) Adopt gantry moving construction, the gantry is welded with steel; tempering processing prevent the gantry from deformation which is caused by welding and dead-weight; whole construction of milling machine has been greatly improved, ensures that the machine's accuracy and long term stability.

2) 4 Axis design on spindle gives the machine more possibility on machining. Another type four axis design available is on rotary which is model 4RS2540C cnc foam router.

3) Anti – dust and anti – water design on X & Y axis is protection for transmission part.

4) Four-row imported ball bearing, widening linear guide rail, self-lubricating sliding block. When engraving, equal force in all directions, to ensure the accuracy and strength.

5) France MOTOVARIO high torque helical planetary gear ensures stable operation with high torque output.

6) All the foundational plane is milled by the 5 axis gantry machining center from our factory; make sure the good accuracy from beginning.

7) The linear guide and rack is detected by horizontal detector, to ensure long-term stability of the foam milling machine. Laser interferometer path revises the machining accuracy.

8) Origin grinding grade ballscrew from Taiwan with unique sealing, long service life, high precision.
