With the continuous development of small batches and high-precision parts, many manufacturers find that dedicated fixture systems cannot provide the versatility they need. On the other hand, the modular system is suitable for small batches or infrequent production runs. The article will mainly introduce the related knowledge of vertical cnc machining fixture.
The working parts of vertical cnc machining are usually enclosed in a metal casing and have a door that allows the operator to use fixtures and tools. The process of vertical cnc machining is concentrated, and the processed parts are usually more complicated. The machining process requires multiple tools. This requires the fixture to withstand greater cutting force and meet the positioning accuracy requirements.
Vertical cnc machining can be defined as a precision machine tool run by a computer and controlled by a program driven by numerical data. It can use multiple areas and multiple areas to perform milling, drilling, tapping and boring under the same position control. Kind of processing operations.
What are the goals of vertical cnc machining fixtures
When determining the process plan, a reasonable choice of positioning reference is of decisive significance for ensuring the processing accuracy of vertical cnc machining and improving the efficiency of the application center. When choosing a positioning reference, the processing of each site should be fully considered to achieve the following two purposes.

1. The selected datum should ensure the positioning accuracy of the workpiece, easy to load and unload, fast and reliable clamping and simple fixture structure.
2. When determining the vertical cnc machining fixture, we must understand that the task of the fixture is not only to clamp the workpiece, but also to use the orientation of the positioning surface as a reference to determine the origin of the workpiece programming. The high flexibility of the machine tool requires that the fixture is more compact and simpler than the conventional machine tool, and the clamping action is faster and more accurate, and the auxiliary time is minimized. On the processing machine, in order to use the fixtures reasonably. First of all, the machining center has a deeper understanding and mastery of the processing characteristics, while also considering the processing accuracy of the parts, the batch size, the manufacturing cycle and the manufacturing cost.
Parts processed on vertical cnc machining are usually more complex. Parts need rough milling and rough boring, as well as fine iron and fine boring that need to be clamped in one piece. Various tools need to be used. These tools require that the fixture can withstand greater cutting forces and must meet the requirements of positioning accuracy. The automatic tool change function of vertical cnc machining also stipulates that brackets, position detection and tool setting components cannot be used in processing.
Fully understand the characteristics of modular fixtures
According to the characteristics and processing needs of vertical cnc machining machine tools, currently commonly used fixture structure types include special fixtures, modular fixtures, adjustable fixtures and group fixtures. When choosing various factors and choosing an economical and reasonable fixture form, comprehensive consideration is also required. The following will mainly introduce the knowledge points of modular fixtures.
Modular fixture is a system of interchangeable components designed to safely and accurately fix the workpiece to be processed, mainly on hole processing machines such as horizontal and vertical vertical cnc machining. In the machining center, by combining the fixture and the fixture on the fixture, these parts series can also be processed at the same time.

Modular fixtures provide a way to replace special fixtures. The fixtures are expensive, require weeks of design and manufacturing time, and take up a lot of storage space when not in use, and can usually only be used for any purpose other than the intended purpose. Unlike special fixtures, combined fixtures can be disassembled into its components at the end of the work, and then reassembled with other components of the system to fix workpieces with completely different configurations.
Modular fixtures provide high stability and accuracy, and have the flexibility to quickly reconfigure various parts. It takes time and effort to design and manufacture special fixtures for specific parts or parts series, and users can quickly assemble modular fixtures, especially if they already have the required fixture components in their tool room.
The article mainly introduces the application of vertical cnc machining fixtures. You can learn about the correct use of fixtures for vertical cnc machining by browsing the article. It is necessary to have a deeper understanding and mastery of the processing characteristics of vertical cnc machining, and also pay attention to the following issues: Precision, batch size, manufacturing cycle, production cost, etc. If you want to know more about the knowledge and application of vertical cnc machining, you can follow us.
