In order to face medical device manufacturing, the industry's extremely high requirements for hole position accuracy, surface cleanliness and durability, AMG has launched a new black-coated precision knife, which is designed for difficult-to-process materials such as stainless steel, titanium alloy and medical plastics.
The tower knife uses ultra-fine grain carbide or high-performance high-speed steel (HSS/PM-HSS) as the TiAlN or AlCrN black PVD coating. While improving the armor and heat resistance, it effectively reduces the weight and thermal deformation generated during the heavy-duty process.
Application areas
Widely used in hole finishing and surface finishing of the following medical device parts:
• Syringe barrels
• Minimally invasive surgical instruments
• High-cleanliness components and so on
It not only ensures the accuracy of the hole size, but also helps to achieve smooth .
Specification Table
| Item | Range / Options |

Working principle
The reamer achieves high-precision adjustment of the pre-drilled hole through multi-edge cutting. The black PVD coating reduces the friction between the tool and the workpiece, make dimensional changes less caused by heat flock and ensures each machining process achieves the desired tolerance range and surface quality.
Product Advantages
Black coating provides excellent wear resistance and heat resistance
Applicable to high hardness materials such as stainless steel and titanium alloy
High-precision control to ensure consistent aperture and shape accuracy
FAQ
Q: Is black coating suitable for processing medical stainless steel?
A: It's very suitable. TiAlN and AlCrN coatings have excellent heat resistance and anti-chipping capabilities, can reduce tool wear and chip build-up issues.
Q: Does it support non-standard customization?
A: Support. AMG can provide comprehensive customization services for micro-diameter, deep hole length, and irregular shanks based on your drawings or technical requirements.
