Tombstones Support Modular Workholding System
To support and complete its modular workholding system, the company offers tombstones with solid machine pallets and integrated magnetic plates. The tombstones are offered in solid G30 cast iron with a double stress-relieving heat treatment or in high-resistance aluminum. A variety of shapes including cubes, crank-webs, angles, plates/subplates and shelves are available. Other workholding solutions can be requested from the company. The product is designed for HMCs and multi-pallet systems that require such structures to support the fixtures and workpieces in the presentation that offers the best use of space and part density. According to the company, the advantages of the tombstones include enhanced rigidity; fixture, machining and finishing accuracy; and reduced machine setup times.
A non-woven porous material with a special coating enables vacuum chucks and tables to hold sheets of metal and other materials more effectively on CNC routing machines. The material, called Vilmill, is used as a substrate between the sheet or plate material to be machined and a suitable vacuum table or vacuum chuck where it is held securely in place by the vacuum.
Bar pullers are cost-effective alternatives to enable automated turning on CNC lathes. This article explains how they work and how shops can benefit from using them.
Modular fixturing makes sense for this manufacturer, whether it's machining one- or two-of-a-kind parts for its custom machine tools or larger quantities for its contract machining business.
