The Temperature

Effect in Turning

In the last few years, the concept and implementation of cooling
solutions for cutting tools has enjoyed a surge of popularity
and enthusiasm as if it had never existed before. CNC machine
manufacturers throughout the world have invested time and
resources to develop solutions that can supply coolant at high
pressures and today all new machines are supplied with a
high-pressure coolant option.

Manufacturers from industries such as aerospace,
automotive, and large part production appreciate the
immense advantage of supplying coolant directly to the
cutting edge and are only ordering machines for milling
centers or turning centers with high pressure coolant
capabilities - minimum 70 bar and up to 300 bar. Mass
production manufacturers are also benefiting from the
integration of ISCAR’s JETCUT tools into their processes.
One of the most serious enemies of carbide inserts is
the high temperature of the materials that results from
the machining process. The average temperature during
machining can range from 300°C to 900°C.
As the temperature rises, the lifespan of the inserts is
shortened. Increased wear can damage workpiece
quality and negatively affect machining properties:
the heat generated between the insert and the
workpiece can cause a change in chip shape and
plastic deformation of the insert. High pressure
starting at 70 bar can be effective in breaking
chips and, in cases when it is difficult to break
chips and the chip formed is long and curled,
coolant applied correctly and under high
pressure can solve this problem.
