Materials used for CNC prototype processing and manufacturing: ABS: transparent, ultra-high temperature resistant, black, imported, domestic, etc. POM (Acrylic), PMMA (Acrylic), MC (Nylon), PC, PP, PA, BT, PVC, etc. Aluminum alloy, copper, etc.

Communication Devices-Machined Parts

After the workpiece is clamped once, the digital control system can control the machine tool to automatically select and replace tools according to different processes, automatically change the machine tool spindle speed, feed amount, movement track of the tool relative to the workpiece and other auxiliary functions, and complete several aspects of the workpiece in sequence. For multi-step processing, the entire processing process is actively controlled by the program and is not affected by human factors of the operator.

Manufacturing process of aluminum alloy prototype model

  1. CNC computer gong. Through CNC processing equipment, according to the programmed path, modifications are made on the basis of the raw materials of the product to obtain the prototype of the aluminum alloy prototype model.
  2. Manual processing. After the prototype of the aluminum alloy prototype model is produced, the appearance of the sample will have some burrs and remaining corners. The staff should smooth it with sandpaper to make the appearance of the aluminum alloy prototype model smooth and beautiful.
  3. Laser engraving is to use laser technology to remove the paint on the surface of the sample to make part of the sample transparent.
  4. Oxidation, that is, anode treatment, uses the effect of electrolysis. Since the oxidation formed after treatment has poor corrosion resistance and low hardness, it is rarely used in the process.
  5. Wire drawing is to draw thin lines on the surface of the aluminum alloy. This treatment will make the texture of the sample better.

Issues that should be paid attention to when processing CNC prototypes:

  1. Determine the processing content of the CNC machining center, determine the installation base surface, processing base surface, machining allowance, etc. of the workpiece, and organize the processing process with the purpose of giving full play to the efficiency of the CNC machining center.
  2. For complex parts, due to various reasons such as thermal deformation during processing, internal stress after quenching, and deformation after parts are clamped, it is difficult to complete the entire process in one clamping. At this time Ability to consider two or more clampings.
  3. When organizing the processing procedures, the principle of starting from rough to fine should be followed. First, organize heavy cutting and rough machining, remove the machining allowance on the blank, and then organize the processing of content that does not require high precision.
  4. Use a large-flow cooling method. In order to reduce the impact of the large amount of heat generated during processing on the machining accuracy, and to improve the tool durability, a large-flow cooling method must be actively used.
