Related Glossary Terms
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
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.

gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
BIG KAISER Precision Tooling, a global leader in high-performance metalworking equipment, has updated its offering of Chip Blowers, which are designed to make removing chips and coolant from parts and machine tables fast, easy and safe. The new Chip Blower has an extended steel shank, from 1.77" to 2.5", for added compatibility with hydraulic and milling chucks.
The Chip Blower automates in-machine cleaning of coolant and chips by delivering high-volume air flow with spindle rotation. When not in use, the Chip Blower fits easily into any automatic tool change system for vertical, horizontal or multi-tasking machining centers. The Chip Blower can be used with automatic tool changers and programmed into a machining cycle, helping to improve machine utilization and increase productivity. The Chip Blower complements the solid construction, fixed blade ChipFan.
The Chip Blower is available with three blade length options and has center-through coolant capability for high-pressure washing.
