CNC Custom Part Stainless Steel Parts Processing Customized Machining
CNC Machining Parts
Utilizing computer numerical control, or CNC, machining is a widely adopted manufacturing
technique that relies on automated, high-speed cutting tools to fashion designs from metal
or plastic stock.
Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers.
The manner in which CNC parts are cut can vary, with scenarios where the workpiece remains
fixed while the tool moves, the tool remains stationary while the workpiece is rotated and moved,
or both the cutting tool and workpiece move simultaneously.
Product Details
CNC milling machines are capable of cutting a wide range of materials, including aluminum,
bronze, copper, ceramics, plywood, various steel alloys, stone, wood, zinc, and various
engineering materials.
This versatility makes them an excellent choice for crafting prototypes during product development.
Furthermore, CNC milling allows for precise and rapid adjustments until the desired final product
is achieved.

FAQ's
1. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
In cases where no specific fillet radius is specified in the 3D model or drawing, fillet radii will be
added by the machinist based on their judgment to enhance machining ease.
To ensure a desired fillet radius, specific details should be provided. For a general understanding,
internal vertical edge radii might surpass 1/3 of the depth, and internal horizontal edges may
either be maintained sharp or incorporate a radius within the range of 0.5mm to 1mm.
2. How do I know my design will be kept confidential?
We prioritize the confidentiality of your design. Our commitment to this is solidified through the
signing and adherence to any non-disclosure or confidentiality agreement.
Moreover, our factory strictly enforces a policy that prohibits the capture of photographs of a
customer's product without explicit permission. Our longstanding reputation is based on years of
handling a diverse range of unique designs, with an unwavering commitment to preventing the
disclosure of proprietary information to any third party.
3. What tolerances can achieve?
Tolerance specifications are not one-size-fits-all and are influenced by factors like part size,
design geometry, the number and size of features, material properties, surface finish, and the
manufacturing process. Upon order confirmation, a Design for Manufacturing review is conducted
to pinpoint areas for potential modification to enhance manufacturability.
Clearly indicating critical tolerance areas in your design is beneficial, allowing for adjustments to
streamline production time and costs. General tolerance guidelines are available for CNC machining
in metal and plastic, plastic injection molding, CNC metals and plastic injection molding materials,
metal 3D printing (+/- 0.5mm), and an expected shrinkage rate of +/- 0.15% for vacuum casting.
It is imperative to specify all manufacturing and technical requirements clearly in the 2D drawings
for accurate adherence.
