DLC coating, also known as diamond-like coating, boasts high hardness (>HV1500) and a low dry friction coefficient (0.05-0.1). It is an oil-free self-lubricating coating. The thickness of DLC coating can reach up to 0.55um, ensuring no issues with dimensions. The latest technology ensures excellent lubrication and heat dissipation (dry type), increasing the service life of the workpiece by 10-50 times and boosting work efficiency by 600%, thereby reducing production costs.
