How is PCD made?

Polycrystalline Diamond (PCD) or PCD tools is diamond grit fused together under high pressure and high-temperature conditions in the presence of a catalytic metal.

PCD manufacturing applies in the process of cutting materials such as aluminium, brass and copper, graphite and non-metal materials.

So, special PCD inserts are ideal if you want to obtain high abrasive resistance and high hardness. They result in a longer lifespan of the cutter and do well with customising designs to fit the exact measurement specifications.

What are PCD automotive cutting tools?

The automotive industry revolves around PCD drills and reamers. And, these cutting tools manufacture the best auto parts making the automotive industry capital of the world.

As for the PCD automotive wheel tools, you need more than a PCD drill bit and reamers. So, here are the PCD tools to manufacture wheels.

How are aluminium wheels made?

The machining of aluminium wheels using wheel repair machines require the designing and manufacturing of specific automotive wheel tools.

Machining cast aluminium wheels can be a demanding application requiring a strong steel body and uniform design. So, being in the automotive industry you will need hardened steel bodies from the start to finish machining centres.

Then, you will be able to place mechanical chip breakers nearly anywhere on the PCD tools modifying the body geometry quickly. And, you will get to turn around new and regrind tools on demand.

This allows us to place mechanical chip breakers nearly anywhere on the tool, modify body geometry quickly.

And get a remarkable turnaround of new and regrind tools on demand.

PCD Right Hand Tool

The PCD right-hand tool is the best choice for manufacturing rims with lips. The reason being, the PCD tool is designed to easily reach the corners of the inside lips during the machining process.

PCD Neutral Tool

PCD Neutral Tool is usually used when manufacturing flat rims that come with no lips. For any rim designs that want to go with simplicity, you can get the best of it using this PCD tool.

PCD Left Hand Tool

If you’re looking to design rims that have a rising centre hub, we recommend you the PCD left-hand tool. This PCD tool comes with a special feature in which the tip of the tool cuts the cone perfectly making the rising centre hub.

PCD left hand tool is needed only when you want to create the rising centre.

Round Bit Tool

With the help of a round bit tool holder, you can machine rims with a curved profile. These PCD diamond cutting tools specialize in making curved wheel rims creating a unique look.

PCD Boring Bar Style Tool

A regular right-hand tool is 6 inches long and is not suitable for machine deep rims. So, a boring bar style tool that comes 12 inches long is the best fit to reach deeper positions.

Also, the cutting tip of the boring bar is at the centre of the tool holder. So, you need a shim block to raise the cutting tip to the centre of the lathe.

Besides, you can machine the back part of the rim using an angled boring bar for better finishing.

There are various angles of this tool in the market but the most common is the 12 inches long boring bar. It comes with a negative 17.5 degree angle that perfectly machines a straight surface.

PCD Lip Cutting Tool

After machining the lips of rims according to their designs, you will need to refinish the back of the lips, either side or both sides.

And, when completing the refinishing process, a special lip cutting tool holder is needed. The lip cutting tool needs to be locked holding the rim with three bolts as safety measures.

How is a smartphone made?

Almost everyone in the world has a smartphone these days. But, not many are aware of how intricate and sophisticated it is to make. Here we uncover how PCD and CBN cutting tools come into action to make the world’s smartphones.

What is PCD Cutting Tools?

Polycrystalline Diamond (PCD) cutting tools or PCD carving tools can cut aluminum, brass and copper, graphite, and other materials like wood, plastic, and CFRP. Basically, PCD cutting tools have high abrasive resistance and high hardness which increases the durability of a phone equipment cutter.

What is CBN Cutting Tool?

Polycrystalline Carbon Boron Nitride (PCBN) also known as CBN cutting tools have high resistance to heat abrasion, perfect for fine finishing, and effective for tolerance control. This makes it 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 help reduce production costs due to more efficient processes of turning and milling.

PCD and PCBN Cutting Tools to Manufacture Phones

The diameter of PCD & PCBN tools is very small when manufacturing smartphones. Actually, they are the same diameter to machine glass and ceramic components in today’s devices.

Indeed, PCD and CBN cutting tools are high-precision tools that are effective in the manufacture of the latest smartphones.

For instance, the Apple iPhone 6 had the bevel on the aluminum housing machined using PCD profile cutters. On the iPhone X model, however, stainless steel was used in the housing frame so CBN cutters were used.

Hence, with rising demands on the design and technology of mobile phone manufacturers, the use of glass and ceramic also rises. The PCD and CBN cutting tools are more in need than ever in the phone manufacturing industry today. These materials offer many advantages including excellent reception quality.

On typical mobile phones, metal housings shield the wave transmission on wireless communications. This also protects from other integrated metal parts and ideally achieved with plastic strips.

However, phones with glass or ceramic housing do not require such shielding. Plus they are more sustainable than plastics and allow greater freedom of design. But, due to their brittleness, hardness, and low thermal conductivity, they require PCD and CBN cutting tools for perfect and clean finishing.

Therefore, the mobile phone manufacturing industry requires the highest precision cutting machinery and tools. PCD and CBN cutting tools are capable of producing very small internal radii and shoulders as well as tiny turned parts.

How do Diamond Tools work?

The manufacturing of precision diamond tools happens for a large variety of applications.

They are infused with a mixture of diamonds and metal alloys for the best cutting performance possible. The materials that are normally used are sapphire, glass, granite, and tile.

In order for the diamond tools to keep cutting, the metal bond around the diamonds should wear away to expose the diamonds. Once machining is complete, the rising heat may damage the tools and manufacturing material. Hence, the process requires utmost precision.

How to get the most out of diamond tools?

Generally, to maximize diamond tools application, you need to follow several basic procedures.

We are here to help your manufacturing process while making the most out of your manufacturing process.

Here’s how we make the most out of diamond tools for your production.

The Right Diamond Tools

We can identify the ideal precision tools for you to use from the information you provide us. Understanding metalworking materials and diamond tool functions are very important, especially during the machining process. This is to prevent any damage to the material and the precision tools.

Therefore, you should always consult diamond tools suppliers who can help you decide. We let our clients know which of our precision tools fit the machining process the best.

By giving you transparency, you can confidently save costs and time to produce precisely cut metal products.

Ideal RPMs of Diamond Tools

If the RPM of the equipment runs too fast, it causes friction and causes extreme heat, damaging the diamond tool. On the other hand, when the diamond tool runs too slow, it drags and creates heat.

Hence, you must set an optimum RPM speed when using a diamond tool to avoid damage to the metalworking products.

That is why we, a professional precision tools manufacturer use an RPM chart to help us fix the ideal RPM for metalworking.

Coolant at Point of Contact

All diamond tools require coolant at the point of contact between the material and tool to cool down the diamond tool.

However, the choice of coolant depends on the application. In essence, coolants range from plain water, water-soluble coolants to minerals and oils. Typically, water is used for sapphire, granite, and glass despite no lubricant.

Oil, however, is not a proper coolant because it makes the machine greasy and may cause contamination.

On the other hand, when machining more dense materials, a better option we use is the water-soluble coolant that has better lubricity.

Expose Diamonds at All Times

PCD tools must be both trued to and dressed on the machine on which they will be used. Doing so will thoroughly expose the diamonds and the diamond tool that are ‘true in running (T.I.R)‘ on the machine.

Basically, truing a tool in the process of squaring a tool so it runs within tolerances. This is usually done with a hard stone that knocks diamonds out.

Whereas the dressing process of the diamond tool takes place afterward to expose the diamonds. The diamonds need to stick up exposed from the bone matrix. Or else, it will be difficult for us to handle the tool, especially new ones.

To know if the diamond tool is correctly dressed, we ensure that there are diamond tails extending from the back of the diamonds. From here, we know that the diamond tool should always run in the direction of the leading edge, away from the tail.

So, we make it a point to dress all the new cutting tools before usage and make sure to frequently redress the diamond tools while using it.

Correct Diamond Tool Accessories

During the cutting process, you must use the right size of flanges or wheel stiffener sets. The most appropriate ones will come with thin diamond blades to firmly hold the tool in place. Doing so will help prevent the blade from walking.

As a result, the diamond tool can last up to 75% longer and minimizes material deformation as well as cracks associated with overheating.
