What are Diamond Cutting Tools?

Generally, diamond Cutting Tools or PCD cutting tools can cut aluminum, brass and copper, graphite, and other materials like wood, plastic, and carbon-fiber-reinforced polymer (CFRP).

Basically, diamond insert cutting tools are used to obtain high abrasive resistance and high hardness. Also, these motives result in a longer life for the cutter in comparison to conventional cutters.

Moreover, they can be customized to fit your exact measurement specifications for high precision.

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).

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

CBN and Diamond cutting tools

Basically, there are materials that can go along with both the PCD diamond cutting tools and some work with either one. It is important that you know what machining materials you are using to understand the functions and parts of CBN and PCD cutting tools.

Uses of CBN Cutting Tools

In general, various industries require the use of CBN precision cutting tools in manufacturing products. Especially the ones in relation to metalwork. Hence, below are the listed industries and their applications.

Uses of Diamond Cutting Tools

In essence, these precision cutting tools are famous for their high precision cutting process that result in neat and precise machined metal products. Moreover, these polycrystalline diamond cutting tools can be used for non-ferrous metal as well as non-metal items. Below are some of the listed materials.

Workpiece	Application
Nonferrous metal	Aluminium, Aluminium alloy, Cast aluminium alloy	Automobile (engines, case, chassis, aluminium wheels, etc.) Aircraft, electric machinery/appliances (cases, housing, compressor parts, etc.) Precision machine (HD cases, cameras, VTR/camcorders, measuring machines, sewing machines, copier drums, etc.) General machinery (hydraulic/pneumatic machines, gas appliances, mechanical parts, etc.)
	Copper, Copper alloy, Cast copper alloy	Automobile and vessel (shafts, pumps, gears, bearings, electric power steering, etc.) Electric machinery/appliances (motors, commutators, heat exchangers, hydraulic components, etc.) General/precision machinery (bearings, bushes, bolts, etc.)
	Tungsten carbide	Cutting of semi-sintered and sintered (metal moulds, etc.)
	Ceramics	Semi sintered and sintered (ceramic industry, bricks, ceramics)
Nonmetal	Plastics (FRP, MC nylon, acrylic, polycarbonate, PCB (glass epoxy + copper foil)). Carbon, graphite, black lead, ferrite, brake shoes, pottery, rubber (soft and hard), etc.

Why are diamonds used in industrial cutting?

Basically, one of the most significant reasons you need to know why diamond insert tools are famous in industrial cutting is their hardness.

Which also means they consist of small particles of industrial-grade diamonds that are perfect as embedment in saw blades, grinding wheels and drill bits.

What is PCBN?

Polycrystalline Carbon Boron Nitride (PCBN) or known as PCBN inserts 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 and CBN tool inserts can help reduce production costs due to the more efficient process of turning and milling.

PCBN Inserts Grades & Characteristics

PCBN cutting tools generally come in various grades and characteristics according to the capacity of work they can uptake. Furthermore, in every grade of PCBN insert cutter produced, they come with 2 options – carbide-backed and solid.

PCBN CB450

• Grain size: 0.5?m-1?m (Sub-?m)
• Has approximately 45% CBN
• Principally TiCN Binder

Mainly, the primary application is for moderately interrupted hard turning and finishing hard milling as well as high-speed continuous turning. It is the most resistant to crater water on the market.

PCBN CB500

• Grain size: 1.5?m (Average)
• Has approximately 50% CBN
• Principally TiCN

Application for moderate to the heavy interrupted turning of all common hardened steels. In essence, its excellent abrasion resistance makes it the ideal choice for cold work tool steels and certain valve seat alloys.

PCBN CB720

• Grain size: 3?m (Average)
• Approximately 72% of CBN
• TiCN Binder

Its usage is for moderate to the heavy interrupted turning of all common hardened steels. it provides an excellent balance of toughness and, crater and flank wear resistance.

PCBN CB850

• Grain size: 2?m (Average)
• Approximately 85% of CBN
• AIWCoB binder for extreme chip resistance

Used for applications such as grey iron fine boring and valve seat machining due to excellent strength and abrasion resistance. This PCBN grade is ideal for heavily interrupted cutting of all hard and abrasion workpiece materials that include metallurgy components.

PCBN CB900

• Grain size: 4?m (Average)
• Approximately 90% of CBN
• Novel binder system to provide the ultimate abrasion and chip resistance.

Generally, PCBN CB900 is ideal for applications where longer tool life is required. Also, it excels in interrupted machining of grey and hard cast irons, hardened steel milling, and in the machining of the majority of valve seat ring alloys.

PCBN CB950

• Grain size: –
• Approximately 95% of CBN
• The Binder phase includes aluminum nitrides and borides

Best for turning and milling of grey and hard cast iron as well as heavy turning of hardened steels; including components such as brake discs, pump bodies and impellers and large rolls.

Uses of PCBN Inserts

Generally, PCBN inserts are widely used in processing

• Pearlitic cast iron
• High chromium and nickel alloy cast iron
• Hardened steel
• Powder metal
• Hard alloy
• Superalloy

Additionally, solid CBN inserts greatly reduce the comprehensive production cost while improving the production capacity and efficiency during the whole production operation.

What are the benefits of using a PCBN Insert?

Excellent cost performance

A benefit of using a PCBN insert is that its service life can be more than 10 times that of carbide insert. Moreover, it reduces the cost of comprehensive cutting tools by 30-50%. This also means that the interval time between replacements is long but the frequency of PCBN insert replacements is less.

High machining efficiency

The efficiency of using a PCBN insert is 5-10 times that of the carbide turning inserts. It also means that it greatly improves the equipment capacity and reduces equipment investment costs.

Excellent surface quality

Basically, PCB insert leaves the surface finish and dimensional precision of the machining workpiece at the grinding level.

Strong universality

You can use a PCBN insert for both dry cutting and wet cutting. Also, one grade is normally suitable to machine various materials.

Application of PCBN Inserts in Automotive Industry

Application of PCBN Inserts in Other Industries

• Wind power industry – Slewing ring, large gear
• Engineering machinery – Rolling mortar wall, slurry pump
• Mining machinery – Piston rod
• Automobile – Combined gear, engine cylinder block
• Powder metallurgy – Planet carrier
