Machining centers come in three general types: horizontal three-axis, vertical three-axis and five-axis machines (four- and six-axis machines exist, but are less common). For a vertical machining center, the X-axis controls left-and-right movement, parallel to the workholding surface; the Y-axis controls front-and-back movement, perpendicular ...

Vacuum workholding is a highly effective technique for holding thin, irregular shaped or non magnetic parts. Although parts with a large surface area are ideal, as the holding force is also large, there are also techniques for holding small parts. Vacuum workholding can be applied in milling, turning, grinding and drilling applications.

The construction of the machine is designed to facilitate service as you only need to loosen three ...

While magnetic chucks have been an accepted method of workholding in surface grinding applications, they are now finding acceptance in general machine shops. Magnetic chucks reduce setup, increase access to the many sides of a workpiece, and simplify workholding. A key advantage of magnetic chucks for workholding is consistent clamping.

The flat surface could also be produced by having rotary motion of multi-cutting edged tool and translatory motion of job. The examples of machines employing such motions are milling, surface grinding machines. Refer Fig. 11.1 (iv). Holes are produced in workpieces by drilling operation. Refer Fig. 11.1 (v).

Workholding is the generic term for any device used to firmly hold your workpiece while machining it. Closely related terms are "jigs" and "fixtures.". A fixture holds your workpiece while it is being cut. A jig holds the workpiece and also guides the cutter. Given CNC, there's little need for jigs as the g-code guides the cutter, so ...

Workholding consists of a combination of positional location together with positive and/or frictional restraint to maintain the workpiece in its correct position and prevent it being displaced by the cutting forces and its own weight. The chapter discusses the principles of location and restraint.

major types of grinding fixtures are those used for surface grinding and cylindrical grinding. The magnetic table is the preferred workholding device on surface grinders. Cylindrical grinding is usually a secondary operation after turning. Often the same center holes used for between-centers turning may be used for grinding the part.

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

Grinding allows high accuracy to be achieved and close tolerances can be held for size, shape and surface texture. Grinding is used to machine large parts, such as machine tool slideways where straightness is important and tolerances are usually specified in microns. Grinding is also used to machine small parts including contact lenses, needles ...
