DCGT PCD Inserts Polycrystalline Diamond Turning Inserts – Double-Sided 55° Rhombus for Aluminum/Copper/CFRP

Short Description:

The DCGT series PCD diamond inserts adopt high-purity diamond sintered body + laser precision forming, with a double-sided 55° rhombus structure, combined with laser chip breaker and large rake angle geometry. Specifically designed for high-speed precision turning and high-gloss mirror finishing of difficult-to-machine materials such as non-ferrous metals, high-silicon aluminum alloys, CFRP, and copper alloys, their service life is more than 10 times that of cemented carbide inserts. They are widely used in precision manufacturing fields such as automotive, aerospace, and 3C electronics.

Key Advantages

Super Hard & Wear-ResistantLong Service Life

PCD hardness reaches up to 8000–10000HV, with high temperature resistance and wear resistance. It can perform continuous cutting without chipping, significantly reducing tool change frequency and production costs.

Laser Chip BreakerEfficient Chip Evacuation

Laser-cut chip breaker on the rake face ensures stable chip breaking, low cutting force, and vibration suppression, guaranteeing dimensional accuracy and machining safety, and increasing cutting efficiency by more than 30%.

Large Rake Angle GeometrySmoother Cutting

Reduces cutting resistance, controls chip evacuation direction, and achieves a surface finish of Ra≤0.05μm, easily realizing mirror high-gloss effect.

Double-Sided UsabilityHigher Cost-Effectiveness

◦ Double-sided cutting edge design doubles the utilization rate, reduces the cost per edge, is compatible with standard tool holders, and enables easy replacement.

Full-Process Quality InspectionStable & Reliable

The cutting edge of each insert is inspected under a 100x microscope, with no chipping or defects, high consistency, and suitable for mass automated production.

DCGT-PCD-Insert-1000
