Roemheld North America’s PC 80 Clamping System for CNC machines is a manual vise that comes in two styles, fixed jaw and self-centering. It features a simple, rigid, all-steel design, and includes clamping jaws with a dovetail-shaped serrated gripping feature that can be quickly reversed or changed out. The vise can hold round inserts, enabling cylindrical parts or billets from 44-95 mm in diameter to be clamped securely. This eliminates the need for additional custom workholding solutions or a set of soft jaws to hold parts of different diameters. Roemheld says the vise can be converted back within a couple of minutes to its conventional role of holding prismatic components.
The PC80 has a stroke up to 62 mm and a clamping force up to 4,500 lbs. The vise is compatible with Roemheld’s five-axis riser, as well as existing quick-change solutions, such as Zero-Point 52-mm pins or a Quintus Pull-Down Bolt.
Mold performance and durability depends on mold base quality, and hole making is a crucial step in the process.
In the last two years, there have been many exciting developments in high-speed machining relative to machining centers and controls, tooling and CAD/CAM systems.
With moldmaking the focus is on injection molding or other mold types that use wire EDM or CNC machining centers to create the mold components. Your typical machining center weighs several tons and has a relatively small working envelope compared to a CNC router. The mill’s massive construction lends itself to machining rigid materials with very tight tolerances. While this type of CNC is suited for injection molding components, it isn’t always the ideal tool for the job when we broaden our scope of moldmaking and the current opportunities in the marketplace
