    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 a certain way to form the machine. One of the forms of connection between the parts is the threaded connection, so the thread is often one of the most common structures on the parts. The most commonly used methods for machining threads are turning, tapping

  • The Method For Improving Lathe Machining Parts Precision

    The Method For Improving Lathe Machining Parts Precision

    CNC lathe machining is currently one of the most widely used machining forms. Compared with ordinary lathes, its machining accuracy is high, and the shape and dimensions of the cnc machining parts are consistent. It can realize one-man multi-machine operation and improve labor efficiency. Reduce the scrap rate and save labor costs. In the automobile manufacturing industry, the hobbing of the drive shaft spline shaft, the processing of axle gears and transmission gears occupy a very important position. The cutting speed of the traditional spline and gear milling machine is slow in the process of spline and gear processing, and

  • Numerical control technology of horizontal milling and boring machining center

    Numerical control technology of horizontal milling and boring machining center

    The horizontal milling and boring machining center embodies the rapid development of domestic CNC machine tools, marking a new breakthrough in CNC technology in my country. The products range from small-size 300mm worktables to large-size 2500mm worktables, from single worktables to double exchange work; from ordinary to precision, high-speed type plus centers, etc. This time, the horizontal milling and boring machining center is the focus of the discussion, because these products have been manufactured in my country for decades, and their manufacturing CNC technology is relatively mature. Generally, the specifications of machine tool worktables are below 2000mm. Beginning in the

  • Bakelite Parts

    Bakelite Parts

    Bakelite is the first plastic product to be put into industrial production. The chemical name of bakelite is phenolic plastic. It has high mechanical strength, good insulation, heat resistance and corrosion resistance. The shortcomings of phenolic resins are poor mechanical properties and are not resistant to oil and chemical corrosion. In order to overcome the above defects, people have modified phenolic resins. Adding different fillers to phenolic resins can obtain modified phenolic plastics with different functions. For example, adding asbestos and mica to the ingredients can increase its acid resistance, alkali resistance and wear resistance, and can be used as

  • Research on Processing Process of Stainless Steel and High Temperature Alloy Steel

    Research on Processing Process of Stainless Steel and High Temperature Alloy Steel

    There are some parts made of stainless steel and high-temperature alloy processing parts in coal mining machinery. There are certain difficulties in the processing of these high temperature alloy machined parts. Now we will discuss some issues. 1 Machinability of stainless steel Stainless steel is divided into three types: ferrite, martensite, and austenite according to the metallographic structure. The main component of ferritic and martensitic stainless steel is Cr, which is often used in the quenched, tempered or annealed state. The comprehensive mechanical properties are moderate, and the cutting process is generally not difficult. The composition of austenitic stainless steel

    What are the common methods of mold polishing?

    With the widespread application of plastic products, such as daily chemical products and beverage packaging containers, the appearance needs often require the surface of the Metal Parts Machining cavity to reach the level of mirror polishing.

  • Some details that need to be paid attention to in CNC machining of shaft parts

    Some details that need to be paid attention to in CNC machining of shaft parts

    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 CNC machining of shaft parts should follow certain rules. This article will come to the specific processing steps and some problems that need attention.

    The diversity of CNC prototype model processing methods?

    The diversity of CNC prototype model processing methods? Do you know the CNC prototype model? The following Pingte precision hardware parts processors will explain to you! With the gradual growth of the prototype industry, the manufacturing process has also been updated day by day. There are 3D printing and silica gel casting. But CNC machining is still the most common way to produce parts. At present, the common methods of CNC machining prototype models are as follows: 1.CNC turning Turning simply involves clamping the workpiece firmly on a rotating plate or mandrel. When the workpiece rotates, the cutting tool is

  • What are the types of cnc parts processing and how to do a good job clamping workpiece?

    What are the types of cnc parts processing and how to do a good job clamping workpiece?

    When starting medical machining, the operator should adjust the feed speed to a very small value, execute in a single block, concentrate on positioning, dropping the tool, and inserting the tool quickly. Put the hand on the stop button and stop immediately if there is a problem, pay attention to the direction of the tool movement. To ensure safe feed, then slowly increase the feed speed to a suitable level, and at the same time add coolant or cold air to the tool and the workpiece.
