Case Study: JS Precision Uses Five Axis CNC To Save The Crisis Of Racing Parts Suppliers
A top-class racing wheel manufacturer was facing production challenges. The two-stage process of "CNC lathe + 3-axis milling machine" had a scrap rate of up to 5%, a unit production time of 47 minutes, and could not fulfill order requirements during the prime seasons of the racing competition.
Core Challenge
There are three major bottlenecks in this process:
- Two clamping leads to a cumulative positional error of ±0.1 mm, which is incapable of satisfying the standard of parts for racing.
- The turnaround time from process to process and clamping/positioning takes up 30% of the total time.
- The production capability per month is just 450 pieces, which makes it difficult to cope with the rush order of 1000 pieces a month.
- The total cost of scrap + rework makes the single piece cost reach $45.
JS Precision's Solution
JS Precision didn't just replace the equipment but rebuilt the complete process. Solution details and data are as under:
1. Equipment Upgrade and Fixture Customization:
A German DMG MORI 50 5-axis vertical CNC machining center was adopted, and self-developed pneumatic precision fixture was utilized. Repeatability is ±0.003 mm, which can complete the whole process without second accession and avoid the error that may happen during secondary accession.
2. Optimization of Tool and Cutting Parameter:
In the case of 6061 aluminum alloy, 12 mm PCD inserts were used to conduct face turning at a linear speed of 800 m/min with feed rate 0.2 mm/rpm. For side milling and drilling, carbide coating tools are used. Dynamic milling strategy allows up to 3.5 mm depth of cut and results in efficiency enhancement by 60%.
3. Programming and Cooling Optimization:
Five-axis linkage optimizes the toolpath to make the tool side edge tangent to the curved surface while side milling, reducing the cutting force by 40%. Meanwhile, the 70-bar high-pressure internal cooling system cools at 25 liters/minute flow rate, keeping the aluminum alloy from sticking or generating a built-up edge, thereby increasing tool life 2.5 times.
Quantitative Results:
Significantly positive results were observed after the implementation of the new solution:
- Single-piece cycle time reduced from 47 to 22 minutes, an increase in machining efficiency by 113%.
- Monthly production capacity grew from 450 pieces to 1440 pieces, output increased by 220%.
- Scrap rate reduced from 5% to 0.2%, with almost zero reworks.
- Single-piece cost reduced to $29, which came out to be a 35% cost-saving, and the new investment is recoverable within 4 months.

JS Precision engineers will provide a comprehensive solution covering process optimization, cost analysis, and risk assessment based on this information.
FAQs
Q1: For a simple shaft part, should I choose a CNC lathe or a conventional lathe?
For IT7 and above or for production work where a high degree of accuracy is required, a CNC lathe ensures reproducibility of parts produced. When only one unit is to be manufactured with a lesser degree of accuracy required, a conventional lathe would be more economical.
Q2: Are the startup costs (programming, fixtures) for CNC machining high?
There are costs involved in setting up, but the cost is evened out in the production of each item. When it comes to complicated parts, the advantage of not having to rework the material later on is way beyond the setup cost.
Q3: Can CNC machine all the materials that a lathe can machine?
Yes, CNC can process all such materials that are processed by lathes, and even difficult-to-cut materials like titanium alloys also can have better handling in the CNC process owing to its controllable parameters and sophisticated cooling system.
Q4: Which is more suitable for small-batch production (e.g., 50 pieces)?
Where simpler components are concerned, the lathe machine takes less time and costs less, for complex components, even for small batch production, the advantage of precision of CNC machine outshines rework loss.
Q5: How do I determine if my design requires 5-axis CNC machining?
For situations where there may be multiple surfaces to be machined that are not orthogonal, or situations where multi-face machining needs to be done in one setup to prevent the addition of errors, 5-axis CNC machining must be done.
Q6: Is the delivery time reliable when choosing a Chinese CNC supplier?
The availability of genuine Chinese Suppliers, transparent about their delivery schedules, is taken care of by JS Precision, which delivers 98% of the orders on time and manages their projects effectively.
Q7: What exactly does "precision" in CNC machining centers refer to?
Positional accuracy (for example, ±0.003 mm), repeatability (for example, ±0.001 mm), and contour accuracy would be considered. The assembly function and longevity of the components would be established by this.
Q8: Can the quality of CNC machining China truly rival that of local suppliers?
Chinese industry leaders employ globally harmonized equipment and quality management processes (e.g., IATF16949). JS Precision's products are of equal quality to local manufacturers, and much lower in price.
