computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
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)
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.
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
To make finding the best fit high-pressure coolant system for any CNC machining application faster and easier, LNS ChipBLASTER has consolidated its 9 product offerings into 3 groups:
- B-Series fixed rate, medium- and high-pressure systems are economical, compact and fit many milling and turning applications.
- F-Series are fixed rate, high-pressure, modular systems with additional options for milling and turning.
- V-Series are variable pressure, modular systems with a large number of options that offer the greatest flexibility for a wide assortment of CNC milling and turning applications.
Effective April 1, 2021 the names of each of these models will also change. B, F or V will be the first letter of each product name. ChipBLASTER options including Chillers, Mist Collectors, Oil Removal Systems, Cyclonic Filtration and Sludge Tank remain unchanged. Additionally, an inexpensive wash wand that uses coolant to wash down the inside of a machine tool, is available for the F- and V- Series systems.
