Beaumont's FH30 Fast Hole EDM Provides Accurate Axis Movement
The FH30 from Beaumont Machine is a fast-hole EDM with 16-axis capability, a rotary table with accuracy ranging from 3 to 5 arcseconds and repeatability ranging to 0.0002".
The FH30 from Beaumont Machine is a fast-hole EDM with 16-axis capability, a rotary table with accuracy ranging from 3 to 5 arcseconds and repeatability ranging to 0.0002". With an electrode capacity of 24" (diameters from 0.012" to 0.250"), this machine is useful for aerospace, medical, power generation and semiconductor applications. Onboard drive resolution and absolute encoders provide high accuracy and rapid traverse speeds ranging to 400 ipm in the X, Y and Z axes, with 200-ipm rapid traverse speeds in the W axis. The X-, Y- and Z-axis travels measure 30" × 20" × 26", and the machine’s spindle speed is 3,000 rpm.
The machine features an automatic electrode changer and robotic toolchangers. Siemens and other CNCs are available.
A new breed of power generators for wire EDMs has options for reducing, even eliminating, one of the unwanted side effects of this very versatile metalcutting process.
Electrical discharge machines, both wire and ram type, have undergone rapid improvements in capability, economical operation, speed and flexibility. New applications are continually emerging as shops discover the advantages of this process.
In many die and mold shops, the choice between ram EDM and CNC milling is far less clear than it used to be. Changing technology is changing the rules.
