An excellent way to improve stability and accuracy in rotating tools applications when applied to Swiss-type and multitasking machines is to improve clamping stability by use of integral collets. What is an integral collet? An integral collet is a tool with a tapered shank for direct mounting on ER collet chucks. When compared to a typical spring collet clamp, the integral collet provides better accuracy and higher rigidity. This feature makes integral collets very promising for use in Multitasking and Swiss-type machines. Iscar offers several tool families with integral collets. Some of them, such as those with MULTI-MASTER adaptations, have internal coolant channels for inner coolant supply.

Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
