Current EDM Inc.’s FT300 five-axis CNC EDM drilling machine features the Siemens 840Dsl control. The fully enclosed machine is designed for production facilities in which machines are placed side-by-side in rows. It is operable and serviceable from both the front and rear machine panels. Moving-gantry design and a stationary worktable increase weight capacity and reduce operator reach for ergonomic part handling.

The machine suits high-tolerance work in the aerospace, medical, automotive and cutting tool industries. Table travels are 12" on the X axis and 6" on the Y axis, with a part-weight capacity of 30 lbs at the tilt-rotary table. Precision slides and a 6" diameter,  10" high cylindrical work envelope enable accurate positioning and drilling of complex parts such as turbine engine components, nozzles, valves, injectors, medical/dental devices and cutting tools. Drilling aspect ratios greater than 300:1 can be achieved with DI water.

The machine features a 24-station electrode changer for high production and unmanned operation. EDM milling expands capabilities by enabling the machining of three-dimensional shapes such as gates and diffusers. A sensitive servo and finely tuned power supply enable the machine to drill with consistent speed, wear and depth control. It won’t bend or collapse long, thin electrodes, and exit-hole break-through speed is optimized for rapid hole-to-hole cycle time.

  • Taking The Fear Out Of Hard Turning

    To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.

  • Successful Application Of Ceramic Inserts

    Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.

    Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
