Today we are going to talk about how to use three different measuring tools, including the steel ruler, calipers, and feeler gauge. How to Use A Steel Ruler? The steel ruler is the simplest length measuring tool. Its length has four specifications: 150, 300, 500, and 1000 mm. The steel ruler is used to measure the ......

According to the use temperature, plastics can be divided into general plastics, engineering plastics, and high-temperature engineering plastics. The high-temperature engineering plastics can be used in environments above 150 ℃. This kind of material has high heat resistance and flame resistance, as well as excellent mechanical performance, aging resistance, dimensional stability, and electrical properties. Let’s take a look at 8 types of high-temp engineering plastics.   ......

Engineering plastics are a type of high-performance material that is often used in structural applications, harsh chemical and physical environments, as well as critical industries. How to choose the best engineering plastic? Focusing on the selection of engineering plastic materials, there are some properties factors that need to be considered.   Engineering Plastic Material Selecti......

A blind hole can be commonly found in machining and engineering, what is exactly a blind hole and how to drill a blind hole correctly? What is A Blind Hole? A blind hole is a hole that is reamed, drilled, or machined to a specific depth without breaking through to the opposite side of the workpiece. Its name derive......

The piston is a type of CNC machined automotive part. You can order more auto parts at Junying. Here, let’s learn about the basics of automotive pistons. Automotive Piston Materials The basic requirements for selecting piston materials 1) The alloy should have a low coefficient of thermal expansion and volume stability when cold and hot alternate. 2) The density of the alloy is small, thus reducing the inertia force of the piston during reciprocating motion. 3) The alloy has sufficient high-temperature strength, high-temperature thermal fatigue strength, and elongation. 4) The materi......

The three jaw electric chuck is the standard workpiece clamping device for most lathe users. This chuck has enough universality and can be applied to a variety of turning processes. However, it is not the best fixture for all machining tasks. The spring chuck is a spare workpiece holding device, similar to the jaw chuck, which also uses mechanical force to fix the parts to be turned. Although the size range of the workpiece provided by the spring chuck is not as wide as that of the jaw chuck, the advantages it provides in terms of speed, ac......

Automatic lathe processing has the characteristics of high performance and high precision. It is suitable for processing small parts such as instruments, electronic parts and mobile phones, especially complicated parts. What are the advantages of automatic lathe processing? What are the daily maintenance items for automatic lathe processing?  Advantages of Automatic Lathe Processing 1. Since the five kn......

The CNC machining feed route refers to the route that the turning tool returns to this point from the tool setting point (or the fixed origin of the machine tool) and completes the machining program, including cutting routes such as cut in and cut out tools and non cutting empty travel routes. The feed route for finishing is basically carried out in sequence along the contour of the part. Therefore, the key to determine the feed route is to determine the feed route for rough machining and empty stroke. CNC machining refers to machining wit......
