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.
Setup for the Surface Grinder provides a comprehensive overview of the steps and considerations involved in setting up a surface grinding machine. Setup includes selecting a grinding wheel, testing and preparing the wheel, selecting the correct workholding and/or fixtures for the operation, mounting the workpiece, and setting cutting variables. >

A surface grinding machine is used to produce a smooth accurate finish on either metallic or nonmetallic materials. It uses a round rotating abrasive grinding wheel that remains stationary (but rotating) while the feed table (with work attached) is run in a reciprocating motion (left and right) under the grinding wheel.
Topics include basic programming characteristics, motion types, tooling, workholding devices, set-up documentation, tool compensations, and formatting. Upon completion, students should be able to write a basic CNC turning program that will be used to produce a part. This course is aligned with NIMS certification standards.
To meet these requirements, it is imperative to select the adequate, often customized, cylindrical grinding machine solution matched with part-specific workholding, and a grinding process that consists of a selection of grinding wheels and dressing tools that work in harmony with each other.

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.

* Adjust the surface grinding machine so that grinding head and worktable are absolutely parallel. * Place a grinding wheel of the proper grain, grade, structure, and bond on the wheel spindle. * Place the guard over the wheel and check security of all adjustable members of the grinding machine for rigidity and lack of backlash.
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 ...

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.
