Bronze Lathe Blade Coating

Depending on the specific shape of the insert, the machine parameters (process, speed, etc.), the material to be machined (heat treatment process, hardness, etc.), different PVDs are recommended.Blade CoatingThe

For end customers, batch processing materials are fixed, you can choose stainless steel, high temperature alloys and other specialized blade coating. For distributors who need to prepare stock, they can consider general-purpose coatings to cope with the needs of different processing materials.

New Plasma Enhanced Arc Source Technology Platform Technical Advantages

Advantage 1--Better magnetic field design, higher dissociation rate, fewer droplets, smoother and more delicate surface of coated film.
Advantage 2 - Stronger arc source energy, denser film particles, higher coating hardness
Advantage 3 - Less coating stress, no tip coating removal

Coating Name	color	Coating hardness (HV)	Antioxidant temperature ℃	coefficient of friction	Coating thickness μm	Application Recommendations
Composite TiN	golden yellow	2000	500	0.25	2-3	General-purpose steel processing; better adhesion resistance
TX-S	golden yellow	3500	800	0.25	4-6	General steel, cast iron, stainless steel universal coating
AML	Purplish black	3300	800	0.3	3-4	General steel processing
AMR	Bronze color	4200	1000	0.3	2-3	For stainless steel, high hardness materials; wear-resistant and high temperature resistant
AMT	grizzly	4000	1200	0.3	3-4	For hard-to-machine materials such as high-hardness, nickel-based alloys, etc.

Naxau CNC Insert Cutting Test Experiment

Experiment:
Interrupted turning was used to check the wear and impact resistance of the coating with the following cutting parameters:
Material: 718HH (hardness 40~42HRC)
Vc = 100m/min
f = 0.25mm/r
Ap = 1mm
Dry cutting
Strong intermittent (4 slots)

reach a verdict

In medium-speed dry cutting roughing, with strong impact conditions, turning and machining HRC40 mold steel, Naxau insert coatings have shown very good wear and impact resistance.

For the same type of high alumina coating, our HAM coating performs better than the high alumina coatings of Company B and Company C in terms of impact resistance and heat resistance on the front blade surface and wear resistance on the back blade surface.
