Chip Breaker Design

Schneidplatten mit Spanbrecher

Besides the manufacturing of extremely sharp cutting edges the new laser technology allows to manufacture all imaginable 3D chip geometries with and without chip breaker function, also for all diamond cutting materials.

Thereby all machining situations are very well controlled because besides the pure 3D chip geometries also finest positive and negative chamfer geometries along the cutting edges can be lasered at the same time. With this combination and a special surface structure in the range of chip design we succeeded with all diamond cutting materials in the dry processing of all NE-metals.

In combination with the ideal chip design and the exclusive machining with the new laser technology the polycrystalline CVD thick film diamond demonstrates its real strength. During the dry processing with chip breaker function the tool life time is 3 to 5 times higher than with all known PDC
grades.

Even the monocrystalline diamond – no matter whether manufactured in natural or HPHT processing – is beaten as expected by the polycrystalline CVD thick film diamond during a lot of applications by 2 to 3 times regarding the tool life.

In the following we show a few chip breaker designs in PDC and CVD diamond:

Chipbraker 1
Chipbraker 2
Chipbraker 3
Chipbraker 4

Cutting Data - Range of application

Due to the new possibilities to manufacture all diamond cutting edges with chip breaker design the fields of application for all diamond cutting materials are considerably extended.

In a first step we offer two designs planned for different applications:

PDC Chip Breaker CB 1

PDC - Chip Breaker
PC 1 - Positive geometry for finish and super finish machining, ap: 0,05 mm to 1,5 mm. Applicable for smallest tolerances at lowest cutting pressure.

Application: thin-walled and instable work pieces.

CVD Chip Breaker CB 2

CVD - Chip Breaker
PC 2 - Slightly negative edge preparation for semi finish, finish and super finish machining, ap: 0,5 mm to 2 mm. Due to an increased cutting pressure a better surface quality at smallest tolerances can be reached.

Application: thick-walled solid work pieces at stable circumstances.

For more details about the machining technique please see our valid main catalogue.

ChipBracer Design CB1 and CB2

The indicated cutting data are recommended values resulting from a chip breaker with the geometries CB 1 and CB 2. Using PDC and PDC-S cutting edges the machining performance should run without emulsion cooling.
