Do you want to extend the lifespan of your cutting tools, boost productivity, or improve quality?
Many in manufacturing face these challenges. Knowing which coating works best and how it impacts tools can make a difference.
This article explains the best coatings for cutting tools based on tool material, type, and products being coated.
Why Are Coatings Important for Cutting Tools?
Coatings on cutting tools extend tool life, boost cutting performance, and improve product quality. Different coatings offer unique benefits, such as reduced friction, improving the removal of waste material during cutting, and increasing tool strength.
1: Extend Tool Lifespan
Coatings form a hard layer on cutting tools, preventing wear and damage. For example, TiN coatings are highly wear-resistant and extend lifespan.
2: Boost Productivity
A longer tool lifespan results in fewer replacements and shortens processing times. Additionally, some coatings lower cutting resistance, enabling faster processing.
3: Improve Quality
Coatings improve the surface quality of cutting tools by smoothing them. For example, DLC coatings, with their hardness and low friction, avoid scratches on materials being cut and create polished, mirror-like finishes.
Best Coatings for Different Cutting Tools
Cutting tools are generally made of two types of materials: carbide and High-Speed Steel (HSS), there are optimal coatings for each. The best coating also depends on the material being cut. This guide explains the ideal coatings for different tool types and materials.
Carbide Cutting Tools
Carbide cutting tools are widely used in various cutting processes due to their high hardness and excellent resistance to wear and heat. The most suitable coating for carbide cutting tools depends on the material being cut and the machining conditions.
1.For Cutting Steel
TiN Coating: Provides high versatility, high wear resistance, heat resistance, and oxidation resistance.
TiAlN Coating: Offers higher hardness and wear resistance than TiN coating.
DLC Coating: Improves lubrication and reduces cutting resistance.
2:For Cutting Aluminum
DLC Coating: Best for cutting aluminum, and it extends cutting tool lifespan significantly.
TiN Coating: Suitable for cutting aluminum but less effective than DLC coating.
3: For Cutting Cast Iron
TiCN Coating: Ideal for cutting cast iron, offering excellent wear resistance and heat resistance.
CrN Coating: Suitable for cutting cast iron, with excellent resistance to high heat and oxidation.
High-Speed Steel (HSS) Cutting Tools
HSS cutting tools are less hard than carbide but more resistant to fracture and impact, and they provide precise processing. However, coating options for HSS cutting tools are fewer than those for carbide cutting tools.
1:For Cutting Steel
– TiN Coating: Common coating for HSS tools.
– TiAlN Coating: Works on HSS tools, but more expensive than Tin coating.
2:For Cutting Aluminum
– TiN Coating: Works on HSS tools, but less effective than DLC coating.
3:For Cutting Cast Iron
– TiN Coating: Works on HSS tools, but less wear-resistant than carbide cutting tools.
