How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

KOVAR parts seal preparation and physical properties

Kovar® is a vacuum-melted iron-nickel-cobalt low-expansion alloy. The chemical composition content is controlled in a very narrow range to ensure accurate and balanced thermal expansion performance. At the same time, strict quality control during the manufacturing process of KOVAR machining parts also ensures balance Its physical and mechanical properties are more suitable for deep drawing, stamping and various cutting processes. Material use Kovar® is used for vacuum sealing of hard glass and ceramics, and is widely used in electron tubes, microwave tubes, transistors and diodes. On integrated circuits, it is used for flat integrated circuits and dual in-line packages. Seal preparation All parts made by Kovar® should be degassed and annealed in a wet hydrogen atmosphere. Hydrogen is injected into water at room temperature and gets wet through blisters. Care must be taken to prevent surface carbonization. The heat treatment furnace must have a cooling chamber that provides the same a

A small inventory of thread cutting methods

In actual processing, the types of threads generally include: ordinary single thread, trapezoidal thread, special thread, special-shaped thread, etc. Among them, ordinary threads are the most widely used. Coarse threads are mostly used for connection, while fine threads are used for the connection of thin-walled parts or parts subject to variable load, vibration and impact load, and can also be used for mechanism fine-tuning. When machining ordinary threads, it is necessary to pay attention to the need for multiple cycle feeds during cutting, and the cutting depth must be reduced in accordance with a certain proportion each time.plastic machining

 If the cutting depth of each tool is the same, the force on the cutting edges on both sides of the thread turning tool will increase sharply as the material removal rate increases, resulting in a decrease in thread accuracy and tool damage. In the competition, internal threads and external threads are relatively common, and the processing is generally less difficult. The main attention should be paid to the calculation of the bottom of the thread.


Compared with ordinary threads, trapezoidal threads have longer length, larger pitch, deeper cutting depth, greater cutting force, higher precision requirements, and greater processing difficulties. The thread cutting methods of CNC lathes generally include: straight approach, oblique approach, staggered cutting, and grooving rough CNC cutting.



(1) Straight forward method. Refers to when the lathe is cutting, the Z-direction does not change when the linear motion is performed, and the X-direction feeds a cutting depth in stages. It is characterized by convenience, quickness, and high efficiency. Generally, ordinary threads with a small pitch can be used. However, because the two edges of the turning tool are cutting at the same time, the chip removal is not smooth, and the force is large, the cnc turning tool is easy to wear, and the chips will scratch the thread surface.



(2) Inclined method. It refers to the Z-direction feed and the X-direction also has linkage, forming a diagonal feed mode. At this time, the thread turning tool always has only one cutting edge to participate in the cutting, the chip removal is smoother, and the force and heat are less than the straight forward method. But when the thread depth is deep and the pitch is large, the phenomenon of knife sticking is easy to occur.



(3) Staggered cutting method. The thread turning tools are staggered in the direction parallel to the left and right side of the thread, respectively, until the bottom of the thread. It is very suitable for large thread cutting, but the programming is more complicated.

(4) Grooving rough cutting method. First, use a grooving tool smaller than the width of the thread turning tool head to rough cut a groove, and then use the thread turning tool for thread processing. Large-pitch threads are often used, but the operation and programming are extremely cumbersome.
