How are auto parts manufactured?

The automotive industry is constantly developing with innovative and transformational process changes. Hence, needing long-lasting auto parts. More than that, the ultimate performances of the auto parts need to excel. Automobile industry deeply needs PCD and CBN tools to complete every component and parts of a vehicle.

With mature technology and rich experience in these high precision cutting tools, , let’s discover the autoparts that need diamond cutting tools CBN tools.

What is PCD Cutting Tools?

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

What is CBN Cutting Tool?

Polycrystalline Carbon Boron Nitride (PCBN) or known as CBN cutting tools have high resistance to heat abrasion that is perfect for fine finishing and effective for tolerance control. They are also suitable for iron, cast iron, sintered material and other hardened materials (HRC50 and above).

PCBN cutting tools are typically applied with inserts and round tools which include endmills, reamers and boring tools. CBN tools can help reduce the production costs due to more efficient process of turning and milling.


How do PCD and CBN Tools help in manufacturing auto parts?

  • Automotive brake discs
  • Automobile cylinder sleeve processing
  • Brake drum processing
  • Automotive transmission
  • Machining, milling and ceramic finishing solution
  • More auto parts

Automotive brake disc

In the past, the processing of automotive brake discs commonly used coated carbide and ceramic blades. Although they could complete the processing tasks, the time consumption and production costs were high and the abrasive resistance was not good.

With CBN inserts introduced, they help manufacturers to reduce tool changing and production costs. CBN inserts come with ultra-high wear and impact resistance. So, it helps with improving processing efficiency.

Automobile cylinder sleeve processing

With PCBN cutting tools, the automobile sleeve has better precision after processing and these tools control deformation when the cylinder block is under pressure. So, the wear rate between the cylinder block and the sleeve is reduced so much more improving the vehicle’s engine efficiency. Not to forget reducing fuel consumption and lower engine noise.

Automobile brake drum processing

Originally, brake drums are made from grey cast iron. The coating carbide tools or ceramic tools can only process 20 to 50 pieces of brake drums. Then, the production needs to be interrupted to change into new tools which consume time.

With CBN tools, especially with the inserts, each edge can process 70 to 100 pieces of brake drums. A CBN insert uses a metal bond agent with super high hardness and wear resistance. So, it naturally improves production efficiency as it is an ideal choice for cast iron cutting.

Automotive transmission

The transmission housing is one of the most important parts of the car that assembles other auto parts such as shafts, sets and gears to keep them in the right position altogether. Therefore, the assembly accuracy of these auto parts box components, the performance and life of the installed machine largely determined by the processing quality of the box itself.

So, as for the cast iron transmission housing blank machining with slag and pores. traditional processing methods are difficult to meet the processing requirements of the transmission housing. With the CBN tool blade, easy loading and unloading are possible. Also, the blade can process 70 to 100 pieces of auto parts improving the processing efficiency by 50 to 70%.


Machining, milling and ceramic finishing solution

PCD cutting tools, on the other hand, are used across the automotive production process beginning from the alloy wheels, cylinder blocks, cam and crankshaft casing machining to milled, bored and reamed gearbox housings.

On top of that, PCD cutting tools are the only viable solution for the finishing of new generation ceramic metal matric composite brake discs. To have a perfect finishing is crucial in the automotive industry, in general, to improve auto parts efficiency at all times.

PCD and CBN tools for other auto parts

  • Metal honing stones for the cylinder block and connecting rod
  • Component grinding solution
  • VVT gear
  • Automobile box processing program
  • Automotive piston, etc.
