CNC精密加工有哪些好处?
CNC精密加工的沉没成本可能比传统加工方法高一点. 然而, 从长远来看, the benefits offered by the process definitely make it worth the extra investment.
What are all the benefits? Introduced to you by Sun-Yee Tech
1. CNC precision machining with tight tolerance control
Tight tolerances are the primary reason for using CNC precision machining.
Some may ask: what are tolerances?
What we make may not be exactly the same size as envisioned. There may be an error. But as long as it is still within acceptable limits, then the item is still usable. And tolerance is also known as dimensional accuracy. It is the slight deviation of the dimensions of a machined part from its CAD blueprint.CNC precision machining uses specialized processes and cutting tools to reduce the tolerance to the smallest possible value. This results in a more accurate part compared to the original blueprint.
2. CNC precision machining improves machining accuracy
Tight tolerances are a direct indication that the final product made by precision machining will be highly accurate. Precision machining is generally performed on parts that need to intermate with other parts. 所以, high accuracy is essential for these specific parts to work perfectly at a later stage.
3. CNC precision machining improves repeatability
The concept of repeatability is one of the key cornerstones of modern manufacturing. Every part manufactured through a process looks similar to every other part to the end user. Any deviation from this replica is usually considered a defect. Precision machining is attractive in this regard. Using high-precision CNC machining, it is possible to make each part identical to the original, with negligible deviations.
4. Low production costs
Since there are no deviations in precision machining, fewer defective parts are produced. As a result, the process can significantly reduce the scrap rate of parts. As a result, material costs are lower. In addition, automated computer-aided manufacturing processes can reduce labor costs. The combined reduction in labor costs and material costs means that CNC machining is less expensive to produce than any alternative.
5. High speed and efficiency
Precision machining involves high-speed robotics that can create parts faster than manual manufacturing on a traditional lathe. In addition, these parts have high accuracy and tight tolerance finishes, so secondary machining is not required. This reduces production time and increases productivity and efficiency on the shop floor.
6. Complex machining capabilities
CNC machines can perform complex machining operations. Examples include 3D surface milling, helical cutting and simultaneous multi-axis machining. They can accurately control the movement of tools and workpieces according to pre-written programs. Machining of complex shapes and structures is realized.
7. Safety
CNC machines replace human labor with computer numerical controls and eliminate the risk factor of human error involved in the cutting process, greatly reducing the potential dangers workers face when using the machines. Workers are also able to move into skill-intensive positions, such as CNC design operations.
8. Reducing human error
Because CNC machine operations are computerized, the impact of human error on machining quality is reduced. Human error, such as fatigue, inconsistent operation and judgment, often leads to poor machining results. Using CNC machines reduces these errors and improves the consistency and accuracy of machining.
