Workholding

The requirements for securing holding parts.

Fixturing needs to be one of the first considerations when buying a new machine, not one of the last.

Designing and machining top jaws for precision chucking applications.

Choosing the best clamping method.

Proper fixturing is critical when machining aerospace components.

An effective chuck maintenance program clears the air of flying parts.

A look at the collet--the 'other' workholding device. Even though collets' roots are firmly planted in the past, they remain an integral part of today's tooling designs.

Modular fixturing offers a flexible and reusable alternative to dedicated fixtures. This article discusses the benefits of modular fixturing and the types of jobs for which a modular system makes economic sense. A description of typical modular fixturing components and how they are used is also provided.

When shouldered parts are held for turning with a draw-in collet, length-control problems can result. This article provides directions for making collet add-ons that allow the machinist to locate the part against the spindle face, providing a consistent length from part to part.

This article guides the reader through the many decisions that must be made when selecting and installing a hydraulic workholding system. Basic hydraulic system design principles and maintenance also are discussed.
