3 Axis CNC Milling Service
3 axis CNC milling is one of the most widely used techniques to make mechanical parts. For many decades, it has been well known to manufacturers and other players in the industrial sector, as well as in many other domains like architecture, design, and art.
3 axis milling is a relatively simple process, using conventional machining tools like the milling machine, which allows the material to be worked on 3 axes (X,Y and Z). The machining tool then proceeds to remove shavings in three basic directions corresponding to the axis of a flat surface.
It is very suitable for parts with a simple design and no need for multi-surface machining. For these simple parts, we will use 3 axis CNC milling processing because it is fast and cost-effective.
5 Axis CNC Milling Service
5 axis milling involves all the axes of 4 axis milling, with an additional rotational axis. 5 axis milling machines are the best CNC milling machines available today, capable of creating precise and intricate parts for artificial bones, aerospace products, titanium pieces, oil and gas machine parts, car molds, medical, architectural, and military products.
For some complex internal design or models with multi irregular surface design, we will use 5 axis CNC milling machine to produce, to improve the overall accuracy and reduce the processing time and cost.
What Materials Can Use For CNC Milling?
Our CNC machine shop can machine virtually any engineering material, including plastics, metals, alloys, foam or tooling board. Here is a list of our standard CNC milling materials available, other materials are upon request.
Aluminum is a highly ductile metal, making it easy to machine. The material has a good strength-to-weight ratio and is available in many types for a range of applications.
Available Surface Finishes of Our CNC Milling Services
Surface finishes are applied after milling and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts. Below are the mainstream surface finish types from DEK:
This is the standard choice, economical and rapid, the parts’ surface will leave visible machining marks. The surface finish is equivalent to 3.2RA μm (125 RA μin).
Polishing is to make the surface smooth by physical friction processing, it is often used to prevent corrosion and remove oxidation. After polishing, the parts have a smoother and brighter finish.
Bead blasting is the process of spraying abrasive on the surface of parts under high pressure, after sandblasting, the metal parts have a satin texture or frosted surface, eliminating the processing marks.
After anodizing, a hard non-conductive ceramic coating will be added on the surface of aluminum parts to improve the wear resistance and retain the metal texture and luster.
Electropolishing is the reverse process of electroplating, which simplifies the metal surface at the micro-level through chemical solution. After electropolishing, metal parts can be more bright and reduce surface roughness.
The black oxide is a chemical conversion coating, it is produced by a chemical reaction between iron and oxide salt in black oxide solution. The corrosion resistance of parts can be improved after black oxidation.
Powder coating can add a layer of solid and colorful polymer coating on the surface of parts, so as to improve the wear resistance and corrosion resistance.
Spray painting is to spray paint on the surface of parts in the air. After painting, the parts have various colors, improve the aesthetic appearance, and make the parts unique, enhance brand awareness.
Other surface finishes are also available. Please click here to learn all surface finish knowledge. Or contact our sales team to get an instant quote.
