Executive Summary

As CFRP becomes increasingly adopted in aerospace and automotive applications for its strength-to-weight ratio, traditional PCD tools face limitations in wear and machining quality. CVD diamond tools generally provide superior wear resistance and thermal conductivity, making them ideal for CFRP.

Pin Power’s vacuum brazing technology ensures robust bonding of CVD diamond to tool shanks, enhancing tool life and machining performance. This white paper details the fabrication, technical highlights, and real-world success of this advanced solution.

Introduction

The shift towards lightweight materials like CFRP in aviation and automotive industries brings new challenges in machining. Traditional tools often suffer rapid wear and fiber delamination.

This paper explores how PinPower’s vacuum brazing technology enables a reliable solution by bonding high-performance CVD diamond inserts to tool shanks, offering both durability and precision.

Characteristics of CVD Diamond

► Extremely high hardness and wear resistance
► Superior thermal conductivity for heat dissipation
► Low friction coefficient for energy-efficient cutting
► Free of metal binders — higher thermal and chemical stability than PCD

Pin Power Vacuum Brazing Technology

 Conducted in vacuum to avoid oxidation and contamination
 Utilizes specially formulated active brazing alloys
 Precisely controlled temperature, vacuum level, and cycle time
 Delivers strong, repeatable, and clean joints
 Designed for consistency and reliability, the PinPower brazing process minimizes dependency on operator experience — delivering uniform quality across all production batche

Fabrication Process of CVD Diamond Tools

► CVD film growth via Hot Filament or Microwave Plasma
► Laser cutting using nanosecond/picosecond/femtosecond pulses
► Edge laser or grinding for sharp, durable cutting surfaces
► Vacuum brazing of inserts onto shanks using Pin Power systems

Application Case Studies

Pin Power CVD diamond tools demonstrate:
► Up to 6× tool life extension vs. traditional PCD tools
► Cleaner cut edges of workpiece due to Lower fiber pull-out and delamination in CFRP
► Better surface finish and consistency in production

Benefit Analysis and ROI Assessment

 Reduced tool replacement and downtime
 Lower scrap and maintenance costs
 Fast return on investment (ROI) due to improved durability and efficiency

Conclusion and Future Trends

Combining CVD diamond with vacuum brazing provides a high-performance solution for machining advanced composites. Demand is expected to grow as more industries seek sustainable, precise, and efficient manufacturing.
