Floyd Automatic Tooling is offering the Master-Clamp workholding system and Master-Guide bushing system, which suitable for machine shops that use sliding-head and fixed-head turning machines.

According to the company, the two products can solve a range of sub-spindle component clamping problems and guide brush issues that are experienced on sliding head machines.

The Master-Clamp system features a rigid collet body — which does not require special sleeves in order to ensure compatibility with the turning machine — and four jaws that clamp the component parallel.

The Master-Guide system features four clamping pads that the company says can improve the accuracy of intricate machining operations. The pads can be supplied in a range of materials and coatings that improve the guiding process and eliminate bar marking that occurs when carbide brushes react with stainless steel bars.

As they do no require any slots at the face of the collets, both systems are unaffected by the issue of swarf ingress travelling up the inside of the collet sleeve and marking the component.

Key features


  • The jaws can be machined specifically to suit a component, including special sections and eccentric clamping
  • Enables the end user to over-clamp components
  • A larger diameter can be passed through inside the Master-Clamp collet, while the jaws clamp the smaller diameter — where clamping force is required
  • Can act as a mini four-jaw chuck


  • Bush can adapt to variations in the bar
  • Can be used for most types of bushing application
