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.
Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.
Modern Industries Inc.’s SpinSelect selectable toolholder allows for quick indexing between its five pockets with a quarter turn of a socket head cap screw. Each pocket can house a different tool, enabling quick changes between operations without requalifying tools.
It is for use on most lathes with a turret or tool post and reduces insert indexing time by up to 85 percent, according to the company. The holder provides coolant through the tool.
