OEM precision cnc turning aluminum parts

What are the matters needing attention for CNC lathe processing aluminum parts?

CNC lathes have a variety of raw materials for processing commodities. Among them, aluminum is one of the most processed parts. When using CNC machine tools to process aluminum parts, if you want to make the processed models and specifications more stable, you must pay attention to the problem of raw material refrigeration in these places, because aluminum die-casting parts may be deformed after refrigeration. This sort of thing is usually unavoidable. At this time try to pay attention to the application of diesel refrigerant, in the power of accurate and accurate measurement should also be considered. When the raw material deforms, it deforms.

Processing technology

The unscientific processing technology is easy to lead to the deviation of aluminum die-casting model specifications. In order to ensure that the basic processing technology (such as cutting CNC machine tool processing "rough after fine, the first end after the hole, after the hot surface" or welding fixture application "minimize the number of clamping and use times") the most important part of the basic processing technology, to try to avoid the aluminum iron pin caused by the processing deviation.

The basic parameters

The cutting speed, cutting speed, cutting coefficient, and tool compensation are all the cutting factors that affect the machining efficiency, which must be paid special attention to. Cutting tool selection

When processing aluminum parts, use special tools as far as possible. Such tools are often more purposeful. For example, aluminum milling special turning tools generally have a larger front Angle and spiral Angle, and sharper cutting edge, which is more conducive to the processing of aluminum parts (such as chip prevention), and the performance index will be stronger after processing.

Stress field level

Aluminum is too soft, so pay attention to the clamping range as much as possible. In addition, during processing, aluminum pieces are roughed and left untouched for a period of time to eliminate stress fields before proceeding to the next production process.

In addition, it is necessary to pay attention to the milling surface and cutting fluid requirements in the process of aluminum parts. There are many factors that affect the efficiency of aluminum processing, so it is necessary to deal with them flexibly and analyze the practical problems deeply. Stable machine tools, effective processing technology, cutting tools as well as the technical strength of operators are factors affecting product quality.

Cutting tool selection

When processing aluminum parts, try to use special tools, generally more targeted. For example, the turning tool used for aluminum milling generally has a larger front Angle and spiral Angle, and the cutting edge is sharper, which is more conducive to the processing of aluminum parts (such as anti-chip accumulation), and the machining performance will be stronger.

In addition, special attention should be paid to the difficulty of milling and the amount of cutting fluid required for the processing of aluminum parts. There are many factors affecting the credibility of aluminum processing, so it is necessary to deal with the processing flexibly and analyze the specific difficulties. Stable machine tools, reasonable processing technology, cutting tools, operators of the technical level, and so on are harmful to product quality factors.

The processing technology

The unreasonable processing technology is easy to cause errors in cast iron specifications and models. In order to ensure the basic processing technology (such as CNC machine tool cutting

Most of the basic processing technology key links such as "first coarse after fine, the first surface after hole, first after hot" or "try to reduce the number of clamping, the formation of fixture" and other key links in the use of fixture tooling), we must try our best to reduce aluminum parts on the iron pin caused by processing errors.

There are many reasons for the deformation of aluminum parts, which are often related to raw materials, parts appearance, production and processing specifications, etc. There are mainly several aspects: deformation caused by blank welding stress, and deformation caused by blank welding stress. Deformation due to cutting force and cutting heat, and clamping force.
