To test adhesion and flexibility. Instrument with bending lever and 14 easily exchangeable cylindrical bending mandrels (2-32 mm dia.). To establish the smallest diameter of mandrel which causes the specimen
coating to fail after bending. Special adjustment and plastic bending roller for quick reproducible test results.
Hardinge Collet Blocks grip round, hex, square or odd-shaped parts and can be used horizontally or vertically on mill tables, flat or angled fixture plates, tombstones or rotary trunnions. Sizes are available from the 1C micro medical machining industry up to the 35J mid-range automotive and aerospace industries. Modular collets blocks are compact with a low profile for increased axis travel and for maximum layout of the workspace. A collet can provide certain advantages over a jaw chuck, vise and other clamping methods.
There are some advantages of using Collet Blocks instead of a standard vise or 3-jaw chuck. A collet automatically centers the workpiece for reduced setup time. Centers remain fixed when the fixture is removed from the machine table. A collet provides equal gripping pressure around the circumference of the part unlike a standard vise or a 3-point contact jaw chuck. Thin-wall parts or delicate materials may crush or distort in a standard vise or jaw chuck. Collets ordered with serrations can add additional gripping power to prevent push-back and radial slipping. Extended-nose collets can provide additional tool clearance. Some collet blocks accept expanding collets to grip a part at the internal diameter. Collet blocks are modular for arranging on a pallet for multiple part processing and quick pallet changeover.
