304 Stainless Steel CNC Machining Parts, Industrial Equipment Tolerance Is 0.03mm
CNC machining overview
CNC machining is a subtractive manufacturing process that uses
computer numerical control (CNC) machines and tools to produce
high-quality, precise parts.
It combines the speed of additive manufacturing with the part
quality achieved by milling engineering grade plastic and metal
parts, thereby enabling custom manufacturers like us to provide
customers with more material choices, better part features, and
higher Quality, more beautiful parts.
In addition, because the parts produced by CNC machining are
comparable to those produced by molding, the process is suitable
for both prototype production and production operation.

Advantages of CNC machining
Compared with other manufacturing methods, CNC machining has many
advantages, including:
• Fast turnaround. For CNC machining operations, once the part
design is approved and loaded onto the machine, production can
begin immediately. This feature allows manufacturers to produce
high-quality, accurate parts within a few days.
• Precision and accuracy. Since the CNC machining process is highly
automated, the accuracy of individual parts is higher, and the
accuracy between batches is higher.
• Versatility and customization. CNC machining is suitable for many
types of materials, including metals and plastics, and can be used
to create various standard and custom shapes and designs. The parts
produced range from simple to highly complex to precise.
• Scalability. This process can be adapted to production runs from
small to large. Since CNC operation only requires CAD/CAM files, it
is both efficient and economical for prototype and production
operations.
CNC machining materials
As mentioned above, CNC machining is suitable for many materials,
such as engineering plastics and metals. Some of the most famous
and commonly used include:
•aluminum. It is highly praised for its excellent corrosion and
temperature resistance and high strength-to-weight ratio.
• HDPE. It has durability, impact resistance and stiffness.
•Low-carbon steel. It has excellent ductility and ductility, making
it suitable for a variety of manufacturing methods, including CNC
machining and sheet metal processing.
• PVC. It is used because of its chemical resistance, corrosion
resistance and flame retardancy.
• Steel alloy. The name includes several different compounds, each
with different properties, such as durability and strength.
•stainless steel. It exhibits excellent corrosion resistance and
crack resistance, and has a good strength-to-weight ratio.
CNC milling and its advantages
CNC milling is a processing technology that uses rotating
multi-point cutting tools to remove material from a blank.
Depending on the design and complexity of the part, manufacturers
usually rely on 3-axis or 5-axis milling processes.
Similar to most CNC machining processes, CNC milling has faster
turnaround time, higher precision and accuracy, and greater
versatility and production scalability. It is commonly used to
produce fixtures, fixtures, functional prototypes and a small
number of production-level components.
General industrial applications
CNC machining has applications throughout the industry.
Manufacturers use this process to produce various prototypes and
production parts for industrial applications. Typical end products
include:
•bushing
• Electronic Component
• Fixtures and fixtures
•axis
Design considerations for CNC machined parts
When designing a CNC machining part, there are several factors to
keep in mind, such as:
•Wall height
•Feature width
• The depth and diameter of the hole
•Thread size and type
•General tolerance and part tolerance
•Size restrictions
