Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

Motor shaft core manufacturing technology

The iron core is an important part of motor products, which are generally made of silicon steel plates with a thickness of 0.35 mm and 0.5 mm. Core stamping manufacturing equipment is important in all aspects of motor manufacturing. Currently, China’s high-speed precision stamping iron filing and core are automatically rivet, iron core is 3 rows, iron core twist groove and rotary rivet, iron core double truss rivet, iron core double row rivet, twist groove rivet, semi-circular stator core rivet, Stator core multi-stack,

For example, the combination of long straight stator core coil and laminated rivet high-speed precision stamping production technology is not inferior to international advanced technology.

Among them, the 3-core high-speed precision stamping manufacturing process for wedge-shaped rivet products is a core material of 50W470 silicon steel plate with a material thickness of 0.5 mm and a material width of 307.5 mm.

These include material take-up equipment, S-leveling equipment, material supply equipment lubrication equipment, high-speed precision presses, and large-scale precision progressive dies. Nail holes for automatic punching guides, rotor piece rivet processing holes, rotor marking holes, rotor weighing holes, rotor groove shapes, rotor plate step holes, rotor plate stacking points, rotor plate holes, rotor chip blanking stack rivets and torsion grooves, The stator chip notch, stator chip marking hole, stator piece weighing hole, stator groove shape, stator plate stack rivet point, stator piece internal hole, and stator parts are punched and riveted for multi-station multi-process continuous punching. It is done and three sets of stator core products are completed at once. The thickness of the core stack is 105 mm. The outer diameter of the stator core is 110.52 mm, and the outer diameter is 55.1 ± 0.01 / 0.02 mm.

It is produced by a large high-speed precision press with a production capacity of 300 tons. The stamping speed is changed from 280 times per minute to 320 times, and the core product is automatically output during the stamping process.
