Wire EDM

South Bend Form Tool has invested in three EDM (Electrical Discharge Machining) machines to produce very precise parts to meet the requirements of their customers.

One of their machines is the Sodick 320 which uses Sodick's linear motor technology providing instantaneous servo time, which maximizes cutting efficiency and accuracy. Since there are no ball screws or couplings, backlash is totally eliminated. This provides several advantages, including improved positioning and cutting accuracy, while providing smooth and vibration free table movement.

The EDM process is an electro thermal process in which a thin metal single-strand wire (electrode) in conjunction with de-ionized water (used to conduct electricity) allows the wire to cut through any hard conductive materials by the use of heat from electrical sparks that can easily machine complex parts and precision components. Depending upon the material thickness and make-up, the angle of cut can be made up to 30 deg off the vertical access.

South Bend Form Tool Company, Inc. is an ISO 9001:2000 certified manufacturer of custom tools and dies for the aerospace, automotive and other technical industries, along with their general contract machining and tooling services. South Bend Form Tool uses the latest technologies to provide the highest level of quality in each of their capabilities and services. All of our equipment meets or exceeds the industry standards for accuracy and product quality. Along with our quality assurance departments trained in all aspects of precision measuring to ensure the highest level of quality time after time. We are proud to have offered the highest level of manufacturing and tooling services since 1953, and now with our focus on the future to come.
