What is a PCD Reamer?

Polycrystalline Diamond (PCD) cutting tools apply in the process of cutting aluminium, brass and copper, graphite and other materials like wood, plastic and carbon-fibre-reinforced polymer (CFRP). So, you can basically use them to obtain high abrasive resistance and high hardness. These motives result in a longer life for the cutter in comparison to conventional ones. Also, these tools customize designs to fit your exact measurement specifications.

To add, the usage of PCD Reamer, specifically, is to enlarge a hole that is in close tolerance range with high surface finish, concentricity and cylindricity. In other words, these PCD reamers achieve the required finish and accuracy at its best with reduced machining time while not needing to create a brand new hole.


PCD Grades and Characteristics

Just as the title speaks for itself, PCD comes in a wide array of grades and characteristics to cater to your automotive part needs and finish desires. So make sure you know what you need.

PCD GC001 is sub-micron grain-sized at 0.5𝞵m-1𝞵m. And, this ultra-fine grain structure is suitable for applications where requires mirror finishes due to its extreme edge sharpness or retention. Hence, you can ideally use it when in need of extreme chip resistance for milling and rough cutting of aluminium alloys. You can as well used this grade for machining titanium and composites.

PCD GC002 is 2𝞵m average grain-sized with increased cobalt for ease of processing. Hence, it is ideal for complex tools where requires excessive processing. And, this grain size is ideal for profile routers and thread cutting tools, as well as in wear part applications. 

This PCD Reamer grade is 10𝞵m average sized-grain which is a workhorse PCD grade ideal for many applications that requires a good balance of toughness and wear resistance. So, this is an ideal grade where you can perform roughing and finishing with a single tool. And, we highly recommend PCD GC010 for low to medium content aluminium alloys. 

PCD GC025 has an average grain size of 25𝞵m in which the grade offers the optimum wear resistance for abrasive machining conditions. That being said, it is ideal for milling and rough cutting of aluminium alloys since they require extreme chip resistance. So, you can best use it for machining titanium and composites. 

In the PCD GC030, the grain size ranges from 2𝞵m to 30𝞵m in which it is considered a multi-modal PCD that gives PCD-GC030 excellent wear resistance, edge strength and edge quality. Adding on, the ideal application areas include MMC, high silicon aluminium alloys, high strength cast irons and bi-metal applications. So, it gives excellent abrasion resistance and good thermal stability.

How many types of reamer are there?

PCD Reamers are usually made custom based on customer’s requirement. For instance,

PCD Drill Reamers

For superior hole quality with dagger style geometry and to eliminate delamination.

PCD Step Reamers

For greater accuracy.

Diamond PCD Reamers

For high-intensity boring that requires more force, precision drilling and heightened stability.

Silver Stainless Steel PCD Reamers

For industrial purposes for its durable nature.

Long PCD Reamers

To allow extra reach.

And many more.

What’s a PCD Reamer used for in the Automotive Industry?

The metal machining world in the Automotive industry is growing very fast. Unlike the PCD reamers, the conventional ones are no longer able to fulfil the below requirements.

The accuracy in product manufacturing is becoming more vital and necessary.

PCD reamers guarantee excellent surface finish with high accuracy for economical machining. Hence, they can help to:

  • Offer long tool-life (10 times longer than the carbide type)
  • Ream holes faster (over 300m/min)
  • Increase work productivity
  • Has tighter tolerances with small margins of error
  • Produce cleaner-edge and high-quality holes
  • Lower overall production costs
  • Increase quality control standard ISO 9001:2015 Certification

Use PCD reamers to maximize smoothness, perfect fitting and optimise functioning. And, with the ever-changing landscape of the automotive industry, you can widely use the high-performance of PCD reamers in the building of high-end automobile parts.

Hence, if you are looking for a reamer that fits the automotive industry, opt to a PCD reamer as engineers highly recommend it compared to the conventional ones.
