Custom Percision Stainless Steel Aluminum Parts CNC Machining Milling Turning Parts
CNC Machined Parts CNC Machining Service
CNC machines function through automated cutting processes driven by a set of operator-provided
instructions known as G-code.
This G-code includes coordinates for specific part features, tool selections, recommended speeds
and feeds, and directives for coolant usage.
The machine control unit (MCU) translates this G-code into instructions for different servo motors
and spindles, enabling the production of the desired part.
Product Details
The advantage of CNC technology is its achievable mechanical properties.
By cutting away from bulk material, rather than thermally transforming it as in injection-molding
or additive manufacturing, all desirable mechanical properties of the metal or plastic of choice are
retained.
More than 50 industrial-grade metals, alloys, and plastics can be machined using CNC milling
and turning.
This selection includes aluminum, brass, bronze, titanium, stainless steel, PEEK, ABS, and zinc.
The only material requirement for CNC machining is that the part has an adequate hardness to be f
ixtured and cut.
Here is a comprehensive overview of the most popular materials.

How To Reduce CNC Machining Costs?
Achieving cost reduction in CNC machining requires a comprehensive approach that optimizes
various aspects of the manufacturing process.
By implementing the following cost-saving strategies, manufacturers can enhance efficiency and
maximize their cost-optimization efforts:
1. Supplier Collaboration:
Collaborating with CNC machine suppliers is valuable for exploring cost-saving opportunities.
Engage with suppliers to negotiate favorable pricing, especially for bulk material purchasing.
Optimize supply chain logistics, improve delivery times, and reduce transportation costs through
strong supplier relationships.
Collaborative efforts can lead to innovative solutions and cost-saving recommendations based on
suppliers' expertise.
2. Design Optimization:
Designing parts for manufacturability is crucial to reduce CNC machining costs.
Streamline the machining process by simplifying geometry, minimizing tight tolerances, and reducing
the number of operations.
Collaborate with design engineers to optimize part designs for CNC machining, reducing production
time, tooling requirements, and overall costs.
3. Material Selection and Standardization:
Careful material selection and standardization can yield significant cost savings.
Choose cost-effective materials that meet specifications to reduce material expenses.
Standardize material options across product lines to simplify procurement, minimize waste, and
enhance machining efficiency.
4. Process Optimization:
Optimize the machining process by evaluating and refining various aspects of production.
Focus on toolpath optimization, minimizing setup time, improving machine utilization, and implementing
lean manufacturing principles.
Increase productivity and lower costs by optimizing toolpaths, reducing unnecessary movements,
and implementing efficient work holding and tool change strategies.
Implement lean manufacturing techniques such as 5S, value stream mapping, and continuous
improvement initiatives.
5. Automation and Robotics:
Integrating automation and robotics into CNC machining processes enhances efficiency and reduces
labor costs.
Automated systems handle repetitive tasks, allowing skilled operators to focus on complex operations.
Robotics facilitate precise and consistent machining, resulting in higher-quality parts and reduced scrap.
Embrace automation and robotics to increase throughput, lower labor expenses, and improve process
control.
By implementing these cost-saving strategies, manufacturers can effectively reduce CNC machining
expenses while maintaining high-quality production, ultimately gaining a competitive edge in the market
