The JFY bending unit is a companion unit to the JFY punch, however, it is a fully independent machine tool. The MZ-40 is designed specifically for bus bar, including U-bends. It is supplied standard with 160mm tooling with 200mm available.
Programming and tool changing are simplified by using a computer graphics program and controller. The MZ-40 has an advanced PC control with graphic simulation software. Through 2-D graphics dimensioning information, the software develops the part profile and bend allowances. Once programmed, the part can be named and saved to the PC.
The MZ-40 utilizes two encoders. The first monitors the punch stroke, used in manual program forming. The backgauge is driven by the servo motor and highly accurate ballscrew. The second is a rotary encoding on the automatic feedback die that monitors the material bend for accurate repeatability of the part. Because of the MZ-40’s repeatability, high accurate bends can be achieved from the very first bend, reducing material waste dramatically.
Switching from angular measurement to stroke measurement allows for infinite selection of the ram stroke and depth of the punch into the die. The stroke function can then be stored for later use on the same piece part. Bending consistency is dependent, of course, on material consistency and programmer expertise.
Electronic Cavity Die
Close tolerance accuracy and efficiency is achieved with the unique electronic cavity die that measures bending angle within ± 0.1° and bending accuracy within ± 0.3°. larger image
CNC Control
The MZ-40 is equipped with an advanced industrial control computer with graphic simulation to achieve automatic angle compensation plus precise backgauge control. larger image
Angular Measurement
Measuring accuracy of ± 0.1° is assured by the computer controlled angular bending technology. The precision Heidenheim feed back scale provides bending accuracy within ± 0.3°. Spring back is automatically compensated by electronic auto-feed back.
