Two different designs for this spindle allow it to be mounted on a lathe's turret or slide (like an add-on live-tool spindle) or mounted in a machining center's toolholder. In either case, the spindle is capable of 30,000 rpm. When driven by an 80-psig shop air supply, the spindle can deliver 75 W of cutting power.
As you look at any of the machine tools on display at IMTS, you may ask yourself, Does my shop have the work it will take to keep this machine cutting?
Don't answer yet. Instead, pause to consider whether that's the right question.
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.
There is a gap between the price of one of this builder's custom machines and the maximum price that even many large contract shops can afford to pay for capital equipment. But that gap is getting smaller.
These two shops used to mill EDM electrodes on their metal cutting machines, but they have now shifted the work to graphite machining centers. Both shops say the advantage isn’t just in the cycle time savings, it’s in the inefficiencies they can now overcome.
