  • Reaming problems arising from the causes and measures to solve them

    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…

  • 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…

  • 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…

  • Problems and solutions that often occur when machining small internal threads

    Problems and solutions that often occur when machining small internal threads

    To facilitate thread processing, this article discusses and summarizes the precautions to be taken in small-size thread processing, the problems that often occur during tapping, the causes and solutions, and the common methods for removing broken taps. The manufacturing unit of a machine is the part, and the parts are connected to each other in…

  • 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…

  • Introduction to the machining of difficult-to-cut materials

    Introduction to the machining of difficult-to-cut materials

    This paper introduces what is a hard-to-cut material, factors affecting the machinability of materials, and cutting characteristics of hard-to-cut materials. The basic concept of improving the machinability of hard-to-cut materials. 1 What is a hard-to-cut material? It is a material with poor machinability. General material performance greater than or less than this indicator (hb>;250, σb>;1000mpa,…

  • Carbon Steel Turning Guide

    Carbon Steel Turning Guide

    The feasibility of using carbon steel depends on whether its mechanical properties (such as tensile strength, yield strength, fatigue strength, impact resistance, and required heat treatment) are suitable for making a certain part. If the properties of carbon steel can meet the requirements of a part, most users will choose carbon steel because it is…

  • The Selection Of Surface Treatment Methods

    The Selection Of Surface Treatment Methods

    Part machining process route refers to the production process of parts, from the blank to the finished product through the sequence of processes. In the development of the process route, in addition to the first consideration of the choice of positioning datum, should also consider the choice of surface processing methods, the degree of concentration…

  • IBAG high-speed electric spindle for Swiss-type machining

    IBAG high-speed electric spindle for Swiss-type machining

    Most of the power tools on CNC lathes have only a limited speed of 5000r/min, for large diameter tools this speed limit will not be a problem, however, most of the machining on Swiss machines is small diameter, for small diameter drills and milling tools, high speed is extremely critical to increase the feed rate…

  • 8 Kinds Of Common Materials For Precision CNC Machining

    8 Kinds Of Common Materials For Precision CNC Machining

    Popular materials chosen by precision machining service providers High precision CNC precision machined parts can be made from a variety of materials, as listed below. Aluminum. Considered exotic in manufacturing, aluminum is probably the most widely used CNC milling material. The ability to machine faster than other materials makes aluminum a more useful material for…

  • The History Of CNC Machining Technology

    The History Of CNC Machining Technology

    Until the 1950s, CNC machines operated primarily on data derived from punched cards, which were still largely manufactured through painstaking manual processes. The turning point in the evolution to CNC was when the cards were replaced by computer controls, which directly reflected the development of computer technology, as well as computer-aided design (CAD) and computer-aided…

  • Why young people do not want to do machining

    Why young people do not want to do machining

    Previously engaged in machinery is still particularly fragrant, but now and the Internet-related industries than it seems a bit inferior, more people did not expect the mechanical industry is still recruiting people, because now the young people would rather go to delivery than engage in mechanical processing, is it true that mechanical processing talent to…
