CNC Machining for Different Metal Materials

Material selection affects strength, weight, corrosion resistance, machinability, and overall manufacturing cost. JCTOP supports custom metal components in materials such as:

Aluminum Alloys

Aluminum is widely used for lightweight structural parts, housings, brackets, frames, and robot components. Grades such as 6061 and 7075 may be selected according to strength, weight, and application requirements.

Stainless Steel

Stainless steel is suitable for components that require strength, wear resistance, or corrosion resistance. Depending on the application, available grades may include 303, 304, 316, and other machinable stainless steels.

Titanium

Titanium can be considered for applications where low weight, high specific strength, and corrosion resistance are important. Its machining process and cost depend on the material grade, component geometry, and technical requirements.

Copper and Brass

Copper and brass are used for selected connectors, fittings, conductive components, and other functional parts. The appropriate grade should be specified according to the part's electrical, mechanical, and environmental requirements.

Please include the required material grade in your drawings or inquiry. If you are unsure which material is suitable, our team can review the application and discuss possible options.

CNC Milling, Turning, and Multi-Axis Machining

Different components require different machining strategies. Depending on the part geometry, our manufacturing capabilities include:

1. CNC milling for brackets, housings, frames, mounting plates, and components with complex surfaces
2. CNC turning for shafts, bushings, cylindrical components, and turned features
3. 3-axis and 5-axis machining for parts requiring different tool access directions
4. Drilling, tapping, and other machining operations for assembly features
5. Additional finishing operations where required by the drawing

For parts with multiple machined features, process planning considers datum selection, tool access, workholding, dimensional relationships, and the number of setups required.

Custom Metal Parts for Robotics and Industrial Equipment

CNC metal machining is used to manufacture functional components across a variety of industries.

Robotics and Automation

Typical parts include robot joint housings, arm links, structural brackets, mounting plates, motor housings, and other mechanical components.

Medical Equipment

Custom metal components can be manufactured according to supplied drawings and specifications for suitable medical equipment applications.

Industrial Machinery

Machined shafts, bushings, fixtures, housings, and mounting components support equipment assembly and mechanical movement.

Product Development

Custom metal prototypes help engineering teams evaluate fit, assembly, mechanical performance, and design details before moving to repeat production.

The feasibility of each component depends on its design, material, tolerance requirements, and application.

Surface Finishing for CNC Metal Parts

Surface finishing may affect appearance, corrosion resistance, wear performance, and dimensional fit. Depending on the material and part requirements, available options may include:

• As-machined finish
• Bead blasting
• Anodizing for suitable aluminum alloys
• Hard anodizing for suitable aluminum components
• Passivation for suitable stainless steel parts
• Electropolishing
• Powder coating where appropriate

Please specify any required color, surface appearance, coating, or functional finish in your inquiry. Critical dimensions and mating features should be considered when selecting a finishing process.

From Metal CAD Drawings to Manufactured Parts

To help us evaluate your CNC metal machining project, please provide:

1. A 2D engineering drawing and/or 3D CAD file, preferably in STEP format where available
2. The required metal grade and material condition, if specified
3. Prototype or production quantity
4. Critical dimensions and tolerance requirements
5. Surface finishing and inspection requirements
6. Target delivery date and shipping destination

Our team can review the information and discuss machining feasibility, material options, manufacturing considerations, and quotation details.
