The class "Surface Grinder Operation" provides step-by-step guidelines on how to grind a rectangular workpiece. Grinding each side of a workpiece requires wheel dressing and other preparatory steps, and then roughing and finishing passes. Workpiece sides are numbered from 1 to 6 in order to track which sides must be ground perpendicular or parallel to one another.

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 ...
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.

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.
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.
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. >
Setup is …
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.
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 science behind workholding in the metalworking shop is fairly basic. Hang on to the blank, casting or forging to be machined, with sufficient grip to allow metalworking processes such as milling, turning, drilling or grinding to be performed. The metalworker's art in workholding is the myriad ways that can be used to accomplish the basic ...
Obsidian Manufacturing Industries, Inc. is a manufacturing company located in Rockford, Illinois. They own all proprietary rights to the brands Arter Precision Grinding Machines, MagnaLift, Magna-Lock USA and Power-Grip. They also provide grinding services to the local area.
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.
