ISCAR doubles the cutting edges on positive rake inserts intended for general turning applications. This economical solution for 80 degree turning provides double-sided robust and positive 4 cutting-edged inserts that easily replace the positive 2 cutting edged inserts. Their dovetail shape fits into a unique pocket design, assuring better insert positioning and stability to guarantee longer insert tool life. The holders can be ordered with or without through-tool coolant channels.
- The new double-sided CXMG inserts operate similarly to CCMT positive inserts and can therefore replace standard CCMT inserts. In some applications, they can also replace standard negative CNMG inserts.
- Double-sided with a positive flank
- Low cutting forces
- Designed with a chipformer for general turning applications
- Lever lock insert clamping system
- Very effective JHP (Jet High Pressure) coolant nozzles directed to the cutting edge for increased tool life, improved chip control and high productivity
- The positive insert flank enables a dove-tailed pocket design for very firm insert clamping

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.
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
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.
