Roughing is a critical stage in the machining process. Its main purpose is to quickly remove excess material from raw materials or semi-finished products to form parts that are close to their final shape. Reasons for roughing include: 1. Improve production efficiency: Roughing usually uses larger cutting depth and feed rate, which can quickly remove […]

Spiral taps and straight flute taps are two common thread processing tools, each with different characteristics and applicable scenarios. Spiral Tap features: 1. Suitable for processing blind hole threads, chips are discharged backward, which helps to improve chip removal efficiency. 2. The selection of the helix angle depends on the material characteristics. For example, when […]

Coating is a technology that applies one or more thin films to the surface of a milling cutter to improve the performance and life of the milling cutter. Common coating materials include titanium, titanium nitride, titanium carbide, etc. The coating process usually uses physical vapor deposition (PVD) or chemical vapor deposition (CVD) methods.Compared with the […]

There are some significant differences in design, material selection, geometric parameters and coatings between end mills for plastics and end mills for steel and aluminium, which are designed to suit the machining characteristics and requirements of different materials. 　　1. Material selection: 　　End mills for plastics are usually made of high-speed steel or carbide, sometimes with […]

Boring tool is a specialised tool for roughing, semi-finishing or finishing existing holes, mainly used for cylindrical hole machining of workpieces such as boxes, brackets and machine seats. Boring tools can be used on boring machines, lathes or milling machines with one or two cutting sections and are suitable for operations such as bore machining, […]

       1. The higher the strength and hardness of the workpiece material, the more work is consumed during cutting, the more cutting heat is generated, and the higher the cutting temperature is. The greater the thermal conductivity of the workpiece material, the more heat is transmitted through the chips and the workpiece, the […]

When selecting the appropriate thread milling cutter, several factors need to be considered, including the type of thread to be machined, material, precision requirements, production volume, machine tool capabilities, etc. Here are some key points to help you make the right choice: 1. Thread Type and Size: Determine whether the thread to be machined is […]

Although centring and spotting drills are similar in name, they are two different drilling tools, and their main application scenarios and principles are also different. I. Definition and characteristics of centring drill Centring drill is a kind of drilling tool used for drilling holes, also known as heart drill and arbor drill. The principle is […]

In actual production, chip processing and transportation are important issues that need to be solved. The main factor affecting the processing and transportation of chips is the shape of the chips. Therefore, the chips need to be classified according to their macroscopic shape. Depending on the workpiece material, tool geometry parameters and cutting amount, the […]

The cutting edge of a milling cutter undergoes an impact load, which varies in magnitude and direction, with each entry into the workpiece. This impact load is determined by the material of the workpiece, the cross-sectional area of the cut, and the type of milling operation. Such an impact load is a test for the […]
