Expectations are high because new machine tools …

A work holding apparatus is used in grinding and polishing very hard and brittle tools, such as monocrystalline or polycrystalline diamond tools, diamond indenters, diamond knives, etc. The work holding apparatus includes a support member to be mounted on the work table, and work operating devices capable of vertical movement, capable of forward and backward …

Hardinge provides workholding products for ID, OD, Universal, tool room, cutter & drill and jig grinding machines. Many products are custom manufactured for a specific application. Wheelhead collets and adapters, workhead spindle sleeve adapters, double-head, high-speed grinding, ID grip expanding, drill, and lens grinding collets are

The three main components of a surface grinding machine are the rotating abrasive wheel, the workholding device, and the reciprocating or rotary table. The abrasive wheel smooths and refines the surface of a material by removing excess material from it. The workholding device (i.e., a chuck) holds the workpiece in place as it is processed.

A chuck is a work holding device. It is used for holding work over a lathe machine, which is having large length and small diameter, and also for jobs, which are unable to mount on between the centers i.e., head stock and tail stock centers. A chuck is also employed when a non-axis symmetrical object is to be mounted over the lathe.

Not long ago, the mention of workholding might call to mind the traditional vise or three-jaw chuck. The integral nature of proper fixturing to successful machining has forever changed that paradigm and made workholding as critical to the manufacturing process as any of the machines or systems of which it is a part.
