WHAT IS CNC MACHINING?

CNC machining, short for computer numerical control machining, is a prevalent manufacturing process that employs automated, high-speed cutting tools to shape designs from metal or plastic materials. 
Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines, NC lathes, CNC routers, WEDM, EDM, CNC Laser cutting machines etc. 
The methods of cutting CNC parts can vary. Either the workpiece remains stationary while the tool moves or the tool stays in place while the workpiece is rotated and moved, and sometimes both the cutting tool and workpiece move together. 
Experienced machinists operate CNC machines by programming tool paths according to the final machined parts' geometry. The CAD (computer-aided design) model provides information about the part's shape. CNC machines exhibit exceptional precision and repeatability, enabling the cutting of various metal alloys and rigid plastics with accuracy. This versatility makes custom-machined parts suitable for various industries, including aerospace, medical, robotics, electronics, and industrial applications. 
KYLT develops on the basis of Magnesium precision machining. Now, we provide custom CNC quotes for more than 40 materials, ranging from common metals such as Stainless steel, Aluminum, Copper, etc to Engineering plastic materials like TEFLON or PEET.

CNC MACHINING FINISHES

Smooth (As-Machined): 

This finish is achieved by using fine tools and minimal feed rates during machining, resulting in a relatively smooth surface. However, it may still have visible tool marks.

Bead blasting involves propelling small glass beads or abrasive particles against the surface to create a uniform matte texture and remove sharp edges. It is often used for aesthetic and functional purposes. 
 
Anodizing: 
Anodizing is an electrochemical process that creates an oxide layer on the surface of aluminum. It enhances corrosion resistance, adds color options, and can improve wear resistance. 
 
Polishing: 
Polishing involves mechanically smoothing the surface using abrasives to achieve a glossy, reflective finish. 
 
Powder Coating:
In powder coating, a dry powder is electrostatically applied to the surface and then cured in an oven, creating a durable, smooth, and even finish. 
 
Plating: 
Plating involves depositing a layer of metal (e.g., chrome, nickel) onto the surface to improve corrosion resistance, appearance, and hardness. 
 
Painting:
Painting is a common method to add color, protection, and visual appeal to a part's surface. 
 
Chemical Treatments:
Various chemical treatments can be used to alter the surface properties, such as chemical etching, passivation, or blackening for specific applications.
 
Brushed Finish:
This finish is achieved by brushing the surface with abrasive materials, leaving fine parallel lines. It provides a distinctive appearance.

CNC MACHINING DESIGN PROCESS

CNC machining design guidelines are essential principles and considerations that should be taken into account when creating designs for parts to be manufactured using Computer Numerical Control (CNC) machining processes. These guidelines play a crucial role in ensuring the successful and efficient production of high-quality components. Here are some key points to consider:
 

Key Points

Considerations

   Material Selection

Choose the appropriate material for the intended application, considering factors such as strength, machinability, and cost. Different materials may require specific tooling and cutting parameters.

   Feature Size and Tolerances

Design features with suitable dimensions and tolerances that align with CNC machining capabilities. Consult with your manufacturer to determine achievable tolerances for different features.

   Avoid Sharp Internal Corners

Internal corners with sharp angles can be challenging to machine accurately. Use fillets or radii to avoid sharp corners and improve machining precision.

   Minimize Undercuts

Minimize the presence of undercuts or features that could prevent the tool from reaching certain areas during machining. Such features may require specialized tooling or additional operations.

   Wall Thickness

Ensure uniform wall thickness in the design, especially for parts intended for casting or molding after CNC machining. Even wall thickness promotes consistent material flow and minimizes defects.

   Consider Machining Direction

Take into account the direction of tool movements during machining. Optimizing tool paths can significantly impact surface finish and machining time.

   Avoid Overhangs

For milling processes, try to avoid large unsupported overhangs as they may lead to vibration, deflection, and poor surface finish. Consider adding support structures or choose alternative machining methods like 5-axis machining.

   Hole Sizes

Select appropriate hole sizes, especially for drilled holes. Avoid extremely small holes that could cause drilling difficulties or compromise structural integrity.

   Add Draft Angles

For parts to be molded or cast after CNC machining, incorporate draft angles to facilitate easy ejection of the part from the mold.

   Consider Post-Machining Processes

Plan for any additional processes such as heat treatment, surface finishing, or coatings that may be required after CNC machining.

   CAD Model Inspection

Validate your CAD model for potential design errors or issues that could affect CNC machining. Ensure the model is accurate, and dimensions are properly defined.

   Communication with Manufacturer

Work closely with your CNC machining manufacturer throughout the design process. They can provide valuable insights, offer suggestions for improvements, and inform you about any design limitations.
