GF Machining Solutions will spotlight mold and die as well as job shop applications at EASTEC 2021 in Booth 1106 (October19-21). For optimizing part processing within those industry sectors, the company will demonstrate the speed, precision and surface finishing capabilities of its 5-axis Mikron MILL S 200 U and its FORM E 350 compact die sinking EDM.

 

The Mikron MILL S 200 U is the perfect combination of linear, rotating and swiveling axes that allow shops to shorten production time with a single part-clamping and 5-axis machining strategy. The machine’s Automated Machine Calibration (AMC) and cooling system also ensure the highest precision possible and superior part surface finishes to reduce the need for secondary manual part polishing operations.

 

As standard, the AMC system makes it possible for an operator to quickly calibrate the machine at any time. For a 45 percent reduction in tool center point drift, the Mikron MILL S 200 U’s powerful internal cooling of all machine components maintains the utmost process stability.

 

A powerful 50,000 rpm Step-Tec spindle allows the Mikron MILL S 200 U to tackle both rough milling and drilling operations while increasing metal removal rates to help shops reduce manufacturing costs. Its table swivels from -120 to +30 degrees and accommodates loads up to 8 kg. A rigid, stable C-frame cast iron machine construction reduces vibrations to deliver high levels of precision and repeatability.

 

Sporting the smallest sinker EDM footprint on the market, the FORM E 350 boasts several design and performance features that enhance a shop’s competitive advantage. Its sturdy C-axis construction, cross table and cast iron frame offer high stability and force reduction, which helps maintain a precise spark gap between the part and the electrode. Regardless of part weight or dielectric volume, the machine delivers consistent accuracy. Integrated glass scales preserve long-term, repeatability and eliminate the need for recalibration as well as any errors found in traditional screw systems due to backlash and wear.

 

The latest-generation Intelligent Speed Power Generator (ISPG) on the FORM E 350 excels at superior surface finishes and precision applications in any conductive material. It overcomes common process challenges for copper electrodes, including electrode wear induced by electrical discharge. ISPG improves machining speeds by 40 percent and reduces corner wear by 50 percent. 

 

Designed for high efficiency, the machine features a programmable dielectric management system with a 270-liter capacity integrated inside the machine cabinet. This system fills and empties the work tank without human intervention to keep the machine in production and is easy to access for routine maintenance.

 

The machine console comes equipped with the user-friendly AC FORM HMI (human machine interface) that is based on a standard Windows® platform and offers interactive graphical assistance so that all operations, such as measurement and machining cycles, are illustrated by graphics/icons for fast operator understanding and ease of use. It provides simple descriptions of machining targets, automatic selection of optimal technology and dynamic parameters adaption. 

 

With an X/Y/Z travel of 17.8" x 9.8" x 9.8" (350 x 250 x 250 mm), the FORM E 350 handles workpieces up to 31.5" x 19.7" x 10.4" (800 x 500 x 265 mm.) It also has a four-position linear tool changer, and because it’s automation ready, the machine easily pairs with a System 3R WorkPartner 1+ robot for unattended night and weekend operation.
