What are the installation methods for cnc machined machining components? In order to process a surface that meets the requirements of a certain part of the machining of metal parts, a hardware machining machine must be used to occupy a certain correct position relative to the tool before mechanical machining machined. This process is commonly referred to as hardware part positioning. Due to the influence of cutting force and gravity during the machining process, a certain mechanism is required to clamp the parts and keep the parts in a certain position. The process of parts from positioning to clamping is collectively referred to as assembly.

How to install cnc machined machining components?



The placement of cnc machined machining components is a very important part of mold processing. It will directly affect the final machining accuracy, product clamping speed and clamping stability, and ensuring the relative relationship between the machined parts will also affect the overall production efficiency. Positioning accuracy plane and design reference, hardware components need to use the machining plane reference to occupy the correct position relative to the equipment when placing hardware components. When the components are installed, they must coincide with the design datum and the axis of the machine tool spindle;


There are many ways to install cnc machined machining components on different machining machines. The placement methods can be summarized into the following three installation methods:

1.Use a dial indicator, drawing needle or visual inspection to directly align the workpiece to obtain the correct position of the workpiece.


When using this method, the CNC machined machining parts occupy the correct position on the equipment, which is obtained through a series of attempts. The specific method is to directly clamp the hardware parts on the machine tool, use the dial gauge or the marking needle on the dial to correct the correct position of the parts by visual inspection, and make corrections while checking until it meets the requirements;

The positioning accuracy and speed of the direct alignment method, the accuracy and method of the alignment, the technical level of the alignment tools and the actual personnel. The disadvantage is that the operation time is long and the production efficiency is low. A lot of operations need to be depended on. Therefore, it is generally used for single-piece, prototype or small batch parts machining production. When the accuracy of CNC machined machining parts is relatively high, for example, when the accuracy positioning is only 0.01~0.03mm, it is unlikely to be used to meet the requirements. Claim. Therefore, it is necessary to use precision measuring tools, and relatively high-level operators are required to use the direct centering method to locate and meet the accuracy requirements of the product;


2. Find the position of the workpiece on the machine tool according to the drawn line


This method is to use the marking needle on the equipment to locate the hardware according to the line drawn on the blank or semi-finished product to get the correct position. Obviously, this method requires one more marking process. The line itself has a certain width, and there will be errors when scribing. When correcting the position of the CNC machined machining parts, the error should be observed. Therefore, this method is more suitable for small-batch parts machining, low-precision, large-volume CNC machined parts;



3. Using fixtures


Fixtures are additional devices for metal parts machining equipment. Before installing the CNC machined machining parts, the position of the tool relative to the tool on the equipment has been pre-adjusted. Therefore, positioning is no longer required when machining parts in batches, which can ensure the technical requirements of machining, is convenient and saves troubles, can effectively improve the positioning efficiency, and is more suitable for machining workpieces. A large number of metal parts;

The above is the placement of metal machining parts. I hope this article can help you. If you have precision metal parts CNC machined machining needs, please feel free to contact us.
