Precision Machining for Fixture and Jig

What is Precision Machining for fixture and Jig?

High-precision fixtures are tools used in industrial production to clamp and hold objects securely in place for better processing or assembly. Renowned for their unparalleled precision, stability, and reliability, these fixtures are indispensable equipment in modern manufacturing.

Precision Requirements for Fixture Machining:

The precision requirements of high-precision fixtures are exceptionally stringent, manifesting in several aspects:

● Positioning Accuracy: The positioning hole pitch accuracy of these fixtures can reach as high as ±5μm, ensuring that the workpiece is held with micrometer-level precision.

● Support Surface Accuracy: The perpendicularity and parallelism of the fixture's support surfaces also adhere to stringent standards, such as perpendicularity up to 0.01mm/300mm and parallelism up to 0.01mm/500mm, ensuring stability and accuracy during processing.

● Repeatability of Positioning: High-precision fixtures boast a high degree of repeatability, with some flexible fixtures achieving a repeat positioning accuracy of 2–5μm. This ensures that repeated clamping of the same workpiece maintains exceptional positional consistency.

Application Fields for Fixture Machining:

Due to their high precision and quality, high-precision fixtures are widely utilized in various industries with stringent precision requirements, including aerospace, medical devices, electronics, precision instruments, among others. These fields demand exceptional precision and performance from components, and only high-precision fixtures can meet these demands.

The Importance by using Fixture :

High-precision fixtures play a crucial role in industrial production. They not only minimize processing errors and enhance efficiency but also guarantee product quality and stability. In modern manufacturing, with the continuous improvement of machine tool processing accuracy and the automation and intellectualization of the processing process, the application of high-precision fixtures is becoming increasingly widespread, further underscoring their significance.
