How to choose a machine tool that suits you?

CNC machine tool is the abbreviation of CNC machine tool (DCM), which is an automatic machine tool equipped with a program control system. At present, there are three types of CNC machine tools in the market: low, medium, and high. Each has its own advantages. This makes friends who buy CNC machine tools feel confused and don't know how to choose a product that suits them.

What kind of CNC machine tool is a good CNC machine tool? As a user, the right is the best. Therefore, users should pay attention to the selection of CNC machine tools: the most expensive may not be the best, and only the CNC machine tools suitable for their own enterprise are the best! If you choose improperly, you will not only make money, but also put your company into the predicament of working for the machine. In this regard, the editor of China Machine Tool Business Network believes that CNC machine tools that allow users to recover their investment in a short period of time are good CNC machine tools.

So, in the machine tool commodity market, how should machine tool users choose their own CNC machine tools? The following are the precautions for the preparation of machine tool enterprise network for your reference.

Need to determine the demand before purchasing

When choosing a CNC machine tool, you must first clarify the object to be processed. Generally speaking, parts with the following characteristics are suitable for processing in machining centers: Multi-process intensive workpieces refer to workpieces that require multiple tools to be processed. For example, the positioning accuracy of the machine tool is high, and the multi-hole machining that meets the accuracy requirements of the positioning hole pitch is very convenient to realize. Recycled parts are suitable for small batch production. Small batch refers to 1-100 pieces, each batch is not large, but it needs to be reproduced.

The user can choose according to the mold to be processed. For low-end mold processing or roughing processes, domestic fast wire machine tools can be used. These machines are cheap, generally between 20,000 and 100,000, with small investment and simple use. At present, there is also a kind of "middle routing", which is actually an improved product of fast routing. It improves accuracy on the basis of technology. Although it is not as good as a slow tightrope walk, it is much higher than a fast tightrope walk. The precision of fast wire feeding is 0.01mm higher than the original 0.02mm, which is very helpful for low-end processing and requires higher precision. For high-precision mold processing, imported wire-cut EDM machine tools can be used, and different brands can be selected according to the accuracy of the mold.

In addition, even if the shape and size of the workpiece are different, it is similar to the workpiece, and it is easy to realize the group machining (GT) process of the parts. Using automatic programming technology, complex-shaped parts such as molds and aviation parts can be processed in the machining center. Boxes and plate parts are processed on a horizontal machining center using a turntable, such as a spindle box, pump body, valve body, internal combustion engine cylinder block, etc. Even if the upper surface needs to be processed in a fixture, a pentahedral machining center can be used. d. The vertical machining center is suitable for processing box heads, cylinder heads, plane cams, etc., and the gantry machining center is used for processing large box plate parts, such as diesel locomotive cylinder blocks, machining center columns, bed bodies, printed wall panel machines, etc.

In the procurement process, the procurement objectives must be correctly analyzed and determined.

When choosing a CNC machine tool, you must first ensure the technical requirements of the processed parts and be able to process qualified parts. The second is conducive to improving production efficiency and reducing production costs. When selecting a CNC machine tool, the influence of factors such as machine tool specifications, machine tool accuracy, and machine tool structure should be considered comprehensively.

Machine specification selection: Determine the size of the machine table and the stroke of the three linear coordinate systems according to the size of the workpiece. The size of the worktable should ensure that the workpiece can be clamped smoothly. The machining size must be within the coordinate range. In addition, the limitation of tool change space and coordinate interference area should also be considered.

Selection of machine tool accuracy: The working accuracy of the machine tool is compatible with the machining accuracy required by the procedure. The machine tool should be selected according to the requirements of the machining accuracy of the parts, such as low-precision rough machining procedures, low-precision machine tools, and finishing
