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 |
|---|
| Material | Ultra-fine carbide / HSS / PM-HSS |
| Coating Type | Black TiAlN, AlCrN |
| Diameter Range | Ø0.8mm – Ø30mm |
| Accuracy Grade | H7 / H8 or per customer request |

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.
