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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Elimination of Gear Backlash in CNC Machining Feed System

Elimination of Gear Backlash in CNC Machining Feed System   The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on th

Custom name plate manufacturer

Nameplate Definition: After the product is put on the market, it is fixed on the product and provides the user with the manufacturer’s trademark logo, brand difference, product parameters and other information nameplates. Nameplates are also called signs. Nameplates are primarily used to record some of the manufacturer’s technical data and correct working conditions for proper use without damage to the equipment.
The materials used to make nameplates are metallic and non-metallic:
The metal is zinc alloy, copper, iron, aluminum, stainless steel and the like. However, the treated nameplate is relatively high quality, durable and does not rust, so aluminum production is mainly used. Non-metallic materials include plastics, acrylic organic plates, PVC, PC and paper.

Category: Bump name plate, flat name plate
Nickname: Logo

wrap up
For example, electrical appliances have a paper nameplate on the exterior. The name plate of the metal plate of the appliance records the manufacturer’s name and product rating technical data.
The Chinese characters used on Chinese nameplates should always use Chinese legal standards. Imported products are sold in the Chinese market and you also need a Chinese nameplate.
National standard for nameplates: GB / T13306-2011
Bump name plate
Nameplate process
Nameplates are embossed nameplates and flat nameplates.
The common concave nameplate and groove-filled paint is lacquer.
The spraying method is to spray the entire front panel and then remove any parts of the paint or font pattern, bare metal or lines of the text pattern. Upon request, the premium bump nameplate is only painted, partially painted, or painted with a clear varnish. Flat nameplates are mainly made of aluminum alloy material. The surface color is not a paint, but a color dyed by anodic oxidation. Depending on the process, it can be monochrome or 2-3 colors. Flat nameplates are highly decorative and relatively inexpensive. Other people’s screens don’t have nameplates and the color used is ink.

Imitation Gold Card:
The color of the card will be dimmed and the surface of the card will easily fade and fade. True gold cards were golden at the time and it took a long time to lose real gold.
Gold card for electrophoresis:
Made with the latest technology, the colors are as shiny as real gold, with a unique embossed three-dimensional effect, the texture is doubled and more noticeable. And you can prevent the product from fading.

DC motor name plate
Domestic motor models are usually represented by Arabic numerals in uppercase Chinese pinyin letters.
The format is: The first part uses uppercase pinyin characters to represent the product code.
The second part uses Arabic numerals to indicate the design number.
The third part uses Arabic numerals to represent the frame code.
The fourth part uses Arabic numerals to indicate the armature core length code.
Equipment factory production equipment Machine nameplate:
Z2 is a general-purpose DC motor, 2 is a design serial number, a second modified design, 9 is a frame number, and 2 is an armature core length symbol.
The first part of the character has the following meanings:
Z series: Universal DC motor (Z2 Z3 Z4 series, etc.)
ZJ series: DC motors for precision machine tools
ZT Series: Wide Speed ​​DC Motor
ZQ series: DC traction motor
ZH series: Marine DC motor
ZA series: Explosion-proof safety DC motor
ZKJ series: DC motor for excavator
ZZJ series: DC motor for metallurgical crane

DC motor name plate

Name plate of electric energy meter
The nameplate of the energy meter has terms such as single-phase, three-phase, active type, and reactive type.
DDSXX, the first D is the “electric energy meter” pinyin prefix, the second D is the “single-phase” pinyin prefix, S is the “static” (commonly referred to as the electron ())) “English Static prefix.
“XXX” represents a different type of power meter produced by different companies.
China uses a 220V voltage system with an AC power frequency of 50Hz.
Particular attention should be paid to the current value of the marker. For example, 5 (20) A means a basic current of 5A and a maximum current of 20A.
Excessive use of electricity is unsafe and can cause a fire.
The nameplate also has one or two logos.
1 indicates that the accuracy of the energy meter is 1% or a level 1 table.
2 indicates that the accuracy of the energy meter is 2% or 2 levels.
Labeled with the standard code, manufacturer and factory number used on the product.
