Characteristics of CNC Prototype Processing

CNC prototype processing and manufacturing: ABS: transparent, ultra-high temperature resistant, black, imported, domestic, etc. POM (Sai Steel), PMMA (Acrylic), MC (Nylon), PC, PP, PA, BT, PVC, etc. Aluminum alloy, copper, etc. 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, the movement track of the tool relative to the workpiece and other auxiliary functions, and complete several workpiece operations in sequence. Multi-step processing on the surface, the entire processing process is actively controlled by the program and is not affected by human factors of the operator.

Issues that should be paid attention to when using CNC machining technology:

(1) 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. This Two or more clampings can be considered.

(2) 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, it is necessary to actively adopt a large-flow cooling method.

Mode.

(3) Determine the processing content of the CNC machining base, determine the installation base surface, processing base surface, machining allowance, etc. of the workpiece, with the purpose of giving full play to the efficiency of the CNC machining base.

Organizational processing procedures.

(4) The process of organizing the processing should be based on the principle of starting from rough to fine. First, organize heavy cutting and rough machining, remove the machining allowance on the blank, and then organize the content that does not require high machining accuracy.

Aluminum alloy prototype model manufacturing skills

1. CNC computer gong. Through CNC processing equipment, according to the path set by the program, modifications are made on the basis of the raw materials of the product to obtain the dimensional shape of the aluminum alloy prototype model.

Aluminum alloy prototype processing

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 refined.

Aluminum alloy grinding

1  Laser engraving is to use laser technology to remove the paint on the surface of the sample to make some parts of the sample transparent.

2  Oxidation , that is, anodizing, uses the effect of electrolysis. Since the oxidation formed after treatment has poor corrosion resistance and low hardness, it is rarely used in the technical process.

Wire drawing is to draw thin lines on the appearance of aluminum alloy. This kind of processing will make the texture of the sample very good.
