Investments in state-of-the-art technologies and experienced, highly trained personnel have kept Kosmo Machine at the forefront of Electrical Discharge Machining.
Our EDM work stations offer four axis EDMs, including a 6-axis machine; 3- and 4-axis die sinker machines; and a small hole popper. The machines can be used to cut conductive materials and are popular in the tool and die industry.
Using electric spark erosion, our EDM technologies create long-lasting carbide wear parts as well as those made of titanium, tool steel, nickel alloys, and tungsten—anything that’s electrically conductive. These durable parts are produced to keep your machines running.
6-Axis Wire EDM
Fanuc Robocut x-C600iB
Our Fanuc Robocut x-C600iB 6-axis wire EDM can create complex workpieces, including holes that can expand or even change shape from front to back, as well as tapering. The machine offers positional accuracy of about 1/10,000 of an inch—about 1/30 the thickness of a single piece of hair.
Cutting conditions are constantly monitored and cutting speeds are automatically increased using Flexible Discharge Pulse Control. Small-feature accuracy is improved as a result, leading to more accurate geometry and straighter walls.
This wire EDM also creates workpieces with improved corner accuracy and smoother transitions. Entrance and exit witness marks are dramatically reduced.
4-Axis Sinker EDM
The 4-axis Mitsubishi Electric EA12S Advance sinker EDM uses graphite or tungsten-copper alloy electrodes—custom made in-house—which are introduced to a positive electrical current. The moving column sinker design provides standard X, Y, and Z-axes to 5-micron accuracy. An additional C-axis rotation allows for the creation of curved holes—a process known as port hole machining.
Power settings are managed utilizing the patented Fuzzy-Logic System, which allows for automatic monitoring of conductivity and electrode gap distance—creating the ultimate control in dimensional stability—while the machine’s Orbit-Pro System assures more consistent side wall and bottom finishes. Both of these features minimize electrode usage, which translates to lower costs for the customer.
These premium wire and sinker EDM machines can achieve superior tolerance. Guided by Computer Aided Engineering—which uses nano interpolation to compute position commands in microns—these machines can duplicate parts within a slim margin of error.
