Same machine tool, yet different production efficiency? Why is that? Actually, it’s… CNC machine tools The improperly selected fixture significantly reduced the production efficiency of the CNC machine tool.
Choosing the right fixture type is the foundation of efficient machining.
Currently, mechanical processing can be divided into two main categories based on production volume: one is single-piece, multi-variety, small-batch production (commonly referred to as small-batch manufacturing), and the other is limited-variety, large-scale production (often called mass production). Notably, the former accounts for approximately 70% to 80% of the total output value in mechanical processing, making it the dominant segment of the industry. 。
Modular Fixture
Combination fixtures, also known as "building-block fixtures," consist of a series of standardized, functionally diverse machine tool components that come in various sizes and specifications. Customers can quickly assemble these components into customized fixtures tailored to their specific machining needs—much like "building with blocks." By eliminating the time required for designing and manufacturing dedicated fixtures, combination fixtures significantly reduce production preparation time, thereby streamlining small-batch production cycles and boosting overall efficiency. Additionally, they offer several key advantages: high positioning accuracy, exceptional clamping flexibility, the ability to be reused repeatedly, reduced energy and material consumption during manufacturing, and low operational costs. For this reason, combination fixtures are often the preferred choice for small-batch machining, especially when dealing with parts that have relatively complex geometries.
Hydraulic/Pneumatic Fixtures
Hydraulic/pneumatic fixtures use oil or compressed air as their power source, employing hydraulic or pneumatic components to precisely position, support, and clamp workpieces. Specialized clamps designed for tight applications.
Hydraulic or pneumatic fixtures can accurately and quickly establish the relative positioning between workpieces, machine tools, and cutting tools. The positional accuracy of the workpiece is ensured by the fixture itself, resulting in high machining precision. Additionally, the positioning and clamping processes are rapid, significantly reducing the time required to secure and release the workpiece. These fixtures also boast a compact design, enabling multi-station setups, supporting high-speed heavy-duty cutting operations, and facilitating seamless automation control.
The aforementioned advantages of hydraulic/pneumatic fixtures make them particularly well-suited for use in CNC machines, machining centers, and flexible production lines—especially ideal for high-volume manufacturing.
Electro-permanent magnetic fixture
Electric permanent magnet fixtures offer advantages such as rapid clamping, ease of multi-station setups, the ability to perform multi-sided machining from a single clamping position, stable and reliable gripping, energy efficiency, environmental friendliness, and compatibility with automated control systems. Compared to conventional machine tool fixtures, electric permanent magnet fixtures significantly reduce clamping time, minimize the number of clamping operations, and enhance overall clamping efficiency—making them ideal not only for small-batch production but also well-suited for high-volume manufacturing.
Use fixtures wisely to unlock equipment potential.
