The most frequently overlooked factor in the EDM process is the filtration method used to maintain the dielectric fluid.
A typical tool and die operation had 12 EDM's, each with its own standard paper cartridge filter or diatomaceous earth filtering system. "The fluid was as black as coal," recalled the foreman. "Forget about being able to see the bottom of the work tank. Two inches under the surface everything disappeared."
Late in 1994, several Charmilles CNC (computer numerical control) EDM’s were installed and integrated with the existing Elox, Sodick and LeBlond Makino units. The project team also recommended installing better EDM filtration systems to cut labor hours and disposal costs. "All filling and draining of the machines is now via the filter and the fluid is filtered to one micron. Even after six months of heavy use, including applications where we pull up to 200 Amps in roughing mode, the oil is absolutely crystal clean."
Their EDM processing showed marked improvements in machining times and finish as well. One operator, who had relocated with his machine from another facility, found that a wrench die that took nine hours using EDM at his previous shop now took only seven hours at the new shop on the exact same machine. On other applications, typical EDM times dropped more than 20% and some as much as 40%.

e, but the one adaptor allows me to use annual cutters in an older mag drill, several different drill presses and milling machines without having to own separate adaptors with shanks that match several morse taper sizes and R8 tooling. Read LessRead less about This is a well machined adaptor that
e Ridgid cast iron table and the Incra fence per the Incra directions. It all works really well. The set up took a little while but it’s sweet! I have done probably 50 cuts and each time I measure with a caliper and it’s dead on front to back on the board I am cutting. I think I am within .004 between blade and fence discrepancies. So for a Ridgid R4512 I’ll take it. Now I have a $1000 package that can hang in terms of accuracy with a nicer cabinet saw. Read LessRead less about So I added the TS-LS 32” to my
, the deal was too good to ignore and figured I would challenge any irregularities with the credit card company later. I also located a coupon code that made the price unbeatable. It must be stated, the expected delivery time on this particular unit was 6 weeks out, adding to my concern. This is the same time frame advised on the Incra web site as well. At probably 5 weeks, I was thrilled to receive delivery notice emails. The large unit came in pristine condition and packaged extremely well. I WILL NOT HESITATE TO BUY FROM CARBIDE PROCESSORS IN THE FUTURE. Thank you for the fantastic deal! Read LessRead less about I had been looking for several weeks
