Spring end improvements Wafios has introduced a new two-plate version of its G 450 spring end grinding machine. The G 450 uses the latest Wafios WPS EasyWay 3.2 control and programming technology, already prepared for future Industry 4.0 applications such as predictive maintenance. Using Wafios iQ Temperature, the temperature of the workpieces can be measured during the grinding process, and controlled according to process specifications. This increases the output while ensuring quality standards. In addition, the machines feature the Wafios particle deflector - a special coating on the suction channel that effectively reduces soiling and deposit of grinding abrasion to a minimum. As a result, maintenance and repair costs can be reduced.

applications, such as spring length measurement and active process cooling. While the former measures the relaxed spring length at the end of the grinding process, to ensure the minimum batch tolerance, active process cooling ensures the safe removal of abrasive dust in the grinding space. New alloy suits fasteners In addition to ultra-fine wires, cables and stranded wires made of Isa-Con ® 414, Isabellenhütte is now manufacturing semi- finished products and preliminary materials for fasteners, such as screws and bolts, made from Isa-Con ® 450, another version of its copper-based alloy. Isa-Con450 is said to reduce electrical resistance and, thus, heat development in the system, and undesired heat is better dissipated. Both types of material, Isa-Con414 and Isa- Con450, are characterized by high strength (similar to that of stainless steel) and high conductivity (similar to that of copper). With Isa-Con450, the tensile strength is between 450 and 550 megapascals and the conductivity is 80 percent ACS (international annealed copper standard). This combination is said to make the material ideal as a conductive fastener, for example as a bolt, screw, spring contact, plug connector or bus bar. When using Isa-Con450 for current-carrying components, the electrical resistance, both in the material and at the contact transition, is reduced compared to

The basic size of the machine has been increased to provide a standard machine that covers most of the industry’s common S S The new two-plate version of the G 450 spring end grinding machine from Wafios
