NEW  Single Shot PCD Diamond Drills for Carbon Fiber

PCD-13520 Series

RobbJack is utilizing a new and revolutionary technology in the manufacture of PCD tools. This new technology improves tool quality, PCD adhesion to the tool body, and increases heat resistance during cutting. All of these improvements allow tool performance that was once impossible.

  • New PCD diamond tip geometry
  • Best holes in carbon fiber
  • Drills and reams in one operation
  • Minimal delamination or uncut fibers
  • Extreme tool life
  • New 135º/20º 8 faceted tip design (Best drill for widest variety of carbon fiber)
  • $548,000 cost savings per year in wing spar case study


CASE STUDY:  Carbon Fiber in Aircraft

4000 clean holes in tolerance when drilling

carbon fiber reinforced polymer (CFRP) wing spars

The Problem:
Prized for its high rigidity and strength-to-weight ratio, CFRP is notoriously difficult to machine without delamination, uncut fibers and fiber pullout. One manufacturer was going through 25 carbide drills to make one ship set of wing spars, scrapping many very expensive parts along the way. The process was intolerably costly and unstable.

Our Solution:

The solid PCD-tipped drill, designed specifically for carbon fiber composites. This powerful, newly developed tool had all the features needed to do the job right, including:

  • A solid polycrystalline diamond tip that outperforms diamond coating in materials with high plastic content, maintaining its edge longer
  • A sharp outer edge that cleanly shears the material without delamination, uncut fibers or fiber pullout
  • An innovative geometry that supports the material as it pierces through
  • A tool life 25 times longer than traditional carbide drills in CFRP applications—and can be extended even further with re-sharpening


Carbon Fiber PCD Trimming Tool

PCD-203-CF & CPCD-203 Series

These PCD routers are best used in trimming composite materials such as fiberglass or carbon fiber CFRP or abrasive materials. The CPCD series comes with a drill point that helps eliminate break out of the material when first plunging into the material. Can be used to rough and finish parts in a single pass eliminating cycle time and linear inches required to cut parts in abrasive materials.

  • Tool life in excess of 7,000 linear inches in carbon fiber
  • Drill tip eliminates fiber blowout during plunging on CPCD-203 Series
  • Roughs and finishes in a single pass
  • 100% inspection guarantees repeatability
  • Typical carbon fiber speeds of 110 ipm
  • Cost savings $210,000 trimming carbon fiber aircraft panels


How to Machine Carbon Fiber

Many companies struggle with machining of new composite materials. Common problems are poor tool life, delamination of layers, and long cycle time. The presentation is set up to give tricks and tips to overcome most of the problems encountered machining modern composites. RobbJack’s Mike MacArthur explains how to solve these issues in the webinar available HERE.


Composite Tips and Tricks

Composite tools present their own special challenges, such as proper fixturing and vibration. And of course, it always helps to get the best tool for maximum life. Read the support article HERE for some tips and tricks.
