Machining Surface Roughness and Factors Affecting Surface Roughness

Surface roughness is one of the important marks to measure the quality of the machined surface, which has a great influence on the wear resistance, corrosion resistance, fatigue strength and fit properties of the parts. However, there are many factors affecting surface roughness in processing. In order to achieve good surface roughness, we will understand what these factors are.

What is machining?

Machining automation production line can be in the case of no human intervention in accordance with the provisions of the program or instruction automatic operation or control of the process, the goal is "stable, accurate, fast". At present, it has been used in the production of casting, forging, stamping, heat treatment, welding, cutting and mechanical assembly. Through the use of machining automation production lines can not only liberate people from heavy manual labor, part of mental labor and harsh and dangerous working environment, but also expand the function of human organs, greatly improve labor productivity, and enhance human understanding of the world and the ability to transform the world.

Quality becomes the support point for the steel industry to adjust the variety structure.

After the steel industry revitalization plan was approved by the State Council, the detailed rules for the adjustment and revitalization of the steel industry as an important supporting measure were also officially released. As an action plan for the comprehensive response measures of the iron and steel industry, the detailed rules clearly define the planning objectives, key tasks, policies and measures for the adjustment and revitalization of China's iron and steel industry in the next three years. Among the eight key tasks for the adjustment and revitalization of my country's iron and steel industry, the sixth is to adjust the structure of steel products and improve product quality. The important position of product quality in the development of iron and steel industry is explained again.

Introduction of plating process for repairing old aluminum alloy parts

Aluminum and aluminum alloy electroplating is more difficult, because aluminum has a strong affinity for oxygen, the surface is easy to oxidize; Aluminum is an amphoteric metal, which is unstable in acid and alkali. The potential of aluminum is very negative, and it is easy to be etched and replaced with plated metal in electroplating solution. The expansion coefficient of aluminum is larger than that of most metals, so the coating is easy to bubble and fall off, affecting the binding force.

China's hardware industry in the change and the same between the return of the king

With the global financial crisis, China's coastal areas of hardware export enterprises are facing an unprecedented survival crisis, a large number of inventory can not be shipped, a large number of payment can not be returned, many enterprises closed down. At a time when the global economy is in recession, the production of Chinese hardware stainless steel products is red against the market. The Chinese hardware industry in a jubilant crisis environment once again shows the king's style to the world.

A number of steel industry support policies are expected to be introduced

In the first half of this year, large and medium-sized steel enterprises made a profit of 7.48 billion yuan, an increase of 4.276 billion yuan over the same period last year, but their main business still lost 0.66 billion yuan and has lost 11 quarters in a row. In the face of this report card, Zhang Changfu, vice president and secretary-general of the China Iron and Steel Association, said that the iron and steel industry should take the initiative to adapt to the new normal and new changes.

Causes of abnormal machining accuracy

The causes of abnormal machining accuracy faults are hidden and difficult to diagnose. Five main reasons are summarized: the feed unit of the machine tool is changed or changed; Abnormal zero offset of each axis of the machine tool; Abnormal axial reverse clearance; Abnormal motor operation state, I .e. abnormal electrical and control parts; Mechanical faults, such as screw, bearing, shaft coupling and other components. In addition, the preparation of processing procedures, tool selection and human factors may also lead to abnormal machining accuracy.

Principles of fault diagnosis for CNC machine tools

After the first external internal CNC machine tool is a set of mechanical, hydraulic, electrical as one of the machine tools, so the occurrence of its failure will also be reflected by the three comprehensive. Maintenance personnel should first check one by one from the outside to the inside, and try to avoid unsealing and dismantling at will, otherwise it will expand the fault, make the machine lose accuracy and reduce performance.
