    Reaming problems arising from the causes and measures to solve them

    In the process of reaming, many problems such as out-of-tolerance hole diameter and high surface roughness of the inner hole often occur. Cause of the problem The aperture increases, the error is large The design value of the outer diameter of the reamer is too large or there are burrs on the edge of the reamer; the cutting speed is too high; the feed rate is improper or the machining allowance is too large; the main deflection angle of the reamer is too large; the reamer is bent; Cutting edge; the reamer edge swing is out of tolerance during sharpening;

  • Use of machining centers

    Use of machining centers

    1. The object to be processed is selected Before determining the object to be purchased, the object to be machined should be clearly defined. Generally speaking, parts with the following characteristics are suitable for machining on a machining center. Workpieces with cumbersome positioning For example, multi-hole machining with a certain hole spacing accuracy requirement is easy to implement by using the machine tool with high positioning accuracy. Repetitive workpieces Suitable for machining small batches of single pieces. Small batch means in 1-100 pieces, the number of each batch is small, but also need to repeat production. Also, parts that are

  • Practical machining dimensions for 55° tapered pipe threads

    Practical machining dimensions for 55° tapered pipe threads

    In sealing mechanisms, 55° tapered pipe threads, with their unique sealing effect, are widely used. However, in machining, the parameters listed in various manuals are invariably given in terms of the base surface as the standard size. This abstract dimension is difficult to measure and control in practice, resulting in threads that vary from person to person and reducing interchangeability. They are either loose or tight in assembly, which not only makes installation difficult, but also seriously affects sealing performance. Now, by replacing the complex base surface dimensions with precise, customarily used end dimensions through conversion, it is not only

  • The basic principle of grinding and its processing capability

    The basic principle of grinding and its processing capability

    Grinding is technically and economically comparable to cutting in many areas, and in some areas it is even the only method of machining. According to Salmon, the main reason for this is a lack of understanding of the principles of grinding and its inherent potential. The author’s purpose in writing this paper is to help those involved in the business community to properly understand and apply grinding technology. Today’s manufacturing industry is eagerly looking for alternatives to grinding. Some of the “new” solutions being tested to improve part productivity include: hard cutting, dry cutting, wear-resistant coated tools and high-speed cutting.

    Why Is The Swiss Machining Process So Famous?

    Swiss machine tools in the end how strong, why the accuracy of machine tools can do the world’s first-class, when it comes to machine tools, the first thing that comes to mind is the accuracy of the machine tool, usually represents the maximum accuracy of the parts that can be processed by the machine tool, we all know that the machining accuracy of machine tools will only lose and not increase, for example: 0.01 mm accuracy of the machine tool can only be processed with an error greater than 0.01 mm workpiece, in such a In this case, in order

  • New Milling Technology Of Machine Tool

    New Milling Technology Of Machine Tool

    The milling technology of the circuit board CNC milling machine includes the selection of the cutting direction, compensation method, positioning method, frame structure, and cutting point. It is an important aspect to ensure the accuracy of milling. Direction Of Cutting And Compensation Method When the milling cutter cuts into the plate, one of the cut surfaces always faces the cutting edge of the milling cutter, and the other side always faces the cutting edge of the milling cutter. In the former, the processed surface is smooth and the dimensional accuracy is high. The spindle always rotates clockwise. Therefore, whether it

    Introduction To The Application Of Several Types Of Commonly Used Machine Tools

    The lathe is mainly used for machining various rotating surfaces and the end faces of the rotating bodies. Such as turning internal and external cylindrical surfaces, conical surfaces, ring grooves and forming rotary surfaces, turning end surfaces and various commonly used threads, equipped with process equipment can also process various special-shaped surfaces. It can also do drilling, reaming, reaming, knurling and other work on the lathe. Milling machine A machine tool with a wide range of applications. On the milling machine, it can process planes (horizontal planes, vertical planes), grooves (key grooves, T-slots, dovetail grooves, etc.), split parts (gears, spline

    Characteristics And Requirements Of Machining Big Parts

    Throughout these emerging industries, we find that their typical products have one common feature, that is, large-scale. From the machining point of view, the workpiece is generally heavy and super heavy, and the size of the workpiece exceeds the machining range of the original machine tool. The machining of large workpieces belongs to the extreme manufacturing category, and many new requirements are put forward for the structure of the machine tool, machining technology, and on-site management. Moreover, we should see that these industries have extremely high requirements for reliability. Safety issues are related to the well-being of the people ’s

  • Tips For Efficient Machining Of Stamping Die Hard Materials

    Tips For Efficient Machining Of Stamping Die Hard Materials

    The stamping dies used for machining metal plates account for a large part of the dies, and most of the stamping dies are used in the automotive industry. The automotive industry and mold manufacturers are increasingly demanding stamping mold production efficiency. Because stamping molds have a large number of machining operations, they have the potential to improve efficiency. The stamping die is a complex stamping tool. Many parts require hard and durable materials, and machining these materials efficiently requires the correct cutting tools and processes. However, most of the machining operations for producing stamping dies are only general metal cutting
