01. The Tap Quality Is Not Good Quality does not include main materials, tool design, heat treatment, machining accuracy, coating quality, etc. For example, the size difference at the transition of the tap section is too large, or the transition fillet is not designed to cause stress concentrati

PEEK has excellent mechanical properties and high levels of corrosion resistance, making it an ideal choice for global manufacturers. This article introduces the basic knowledge of machining PEEK: the material properties of PEEK, the advantages of machining PEEK, the common application

Milling of curved surfaces belongs to the category of contour/contour CNC milling. It involves machining irregularly shaped contours or continuous curves with different angles (inclined, concave or convex). This is the key process to complete most of the customized parts with unique shapes

There are many reasons for the deformation of aluminum parts, which are related to the material, the shape of the parts, and the production conditions. There are mainly the following aspects: deformation caused by internal stress of the blank, deformation caused by cutting force and cutting heat

The important position of tool selection in machining is self-evident. Learning to choose a tool can help you work with ease. Therefore, 15 rules for tool selection should be taken seriously. 1. The Most Important Thing In Processing Is The Tool When any tool stops working, it means that product

In precision machining, the requirement of straightness is very important for parts, so this article will introduce straightness, mainly introducing the definition, symbols, tolerances, measurement methods and common problems of straightness. Straightness (GD&T) Definition Shape control can

CNC lathe is one of the most widely used CNC machine tools. It is mainly used to process symmetrical rotary parts, such as shaft parts, inner and outer cylindrical surfaces of disc parts, inner and outer conical surfaces with arbitrary cone angles, complex revolving inner and outer curved surfac

As the manufacturing industry becomes more and more competitive, the top manufacturers on which the industry can rely are very scarce. In addition, each manufacturing activity carried out within the company will add a heavy burden to the company in addition to other management activities. To sol

Aluminum is one of the most common metals on earth. It also performs a range of functions in industries ranging from automotive, aerospace to construction. Its alloy is unique in nature and has awesome features. What we particularly need to control during the machining of aluminum profiles is th

In machining operations, heat energy plays a very important role. Due to the presence of thermal energy, various adverse effects will be produced on the tool and the workpiece. When the cutting temperature is slightly higher, it is very unfavorable for the cutting tools and workpieces to be proc

At present, the world is transitioning from an industrial economy to a digital economy, and the manufacturing industry is and will be in the historical stage of digital transformation and development, leaping continuously along the stages of digitalization, intelligence, networking, and automati

Quality is the key to a company’s success. Any machining industry attaches great importance to product quality. Therefore, the inspection tool for the product is particularly important, so today I will introduce you to the vernier caliper, the basic inspection tool in the machining industr

In the actual processing of the workpiece, we should also choose the correct operation method reasonably according to the specific workpiece processing accuracy and process requirements and specific processing conditions to ensure the accuracy of the product. The accuracy of the machining center

Consider the two surfaces shown. Which surface is completely flat? In fact, no surface is completely flat. How do we design a surface that is not completely flat but flat enough to function properly? Flatness control tolerance. In this article, we will introduce flatness marking, tolerances, me

Quenching and tempering treatment: the heat treatment method of high temperature tempering after quenching is called quenching and tempering treatment. High temperature tempering refers to tempering between 500-650°C. Quenching and tempering can make the performance and material of steel be adju

According to ASME Y14.5 2009 GD&T standard, 14 geometric tolerances are divided into 5 groups. Circular runout belongs to the category of “Runout”, which is used to control the shape of the circular elements of the surface and their relationship with the reference axis. In this a

Quality is the key to a company’s success, and the machining industry attaches great importance to product quality. Therefore, product-specific inspection tools are particularly important, so today we will introduce you to the microscope, which is the inspection tool in the machining indus

What is precision parts machining, small and exquisite, no matter from the material and craftsmanship, it is made with very careful craftsmanship. It is not a batch-produced part, but also a kind of mechanical processing. For precision parts, processing is very strict. The precision of parts als

Shaft parts are a common type of parts. Its structure is a rotating body, and its length is generally greater than its diameter. It is widely used in various mechanical equipment to support transmission components, transmit torque and bear loads. The machining of shaft parts must follow cer

With the improvement of people’s living standards, people increasingly like things with metallic texture, which also makes aluminum products more and more used in many industries. Compared with steel and superalloys, it is a soft metal, and the hardness of HRC is not high, but it is more t
