Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
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.
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.
BIG KAISER announces the MEGA Micro Coolant Nut, a developed solution to provide precise coolant supply to micro cutting tools applications at high speeds.
Achieving efficient coolant delivery has become an important feature to have across the industry. Without precision coolant, chip jamming may be a problem, causing machine stoppages, service call outs, increased tool wear and poor surface finish. As spindle speeds continue to increase though, getting the coolant to the cutting tip has become more challenging.
Exclusively for MEGA Micro Chuck 6S, the MEGA Micro Coolant Nut is an ideal design for high-speed micromachining up to 6mm in diameter. By using it instead of a standard nut, tool lifetime is increased by about 35 percent and better cutting performance is achieved for milling applications.
The MEGA Micro Coolant Nut is a continuation of BIG KAISER’s efforts to drive coolant towards the cutting edge and help to maintain process security. For coolant-through drills, BIG KAISER offers the MEGA Micro Perfect Seal Nut.
