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

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

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

It is not advisable to add too much oil to vehicles in winter

Car maintenance is essential in the changing seasons. If the car is not maintained before the winter, it will produce very serious wear and tear, which is equivalent to the wear and tear of several years of running under normal maintenance. How can I choose the right product for my car?

The temperature drops significantly in autumn and winter. Ordinary products become thicker when the temperature is low, and their fluidity is weakened. It takes longer to reach the parts that need lubrication, which makes the vehicle difficult to start and wears more. Therefore, in autumn and winter, it is best to choose a product with a lower base oil viscosity, so that it can continue to bring good lubrication to the car engine.

Winter and summer engine oil is **

First of all, the choice should be made according to the requirements, neither can use too high-grade engine oil on the lower requirements, nor can the lower-grade engine oil be used on the higher requirements. The choice can be increased by one level on the basis of the manufacturer’s recommendation, or the performance of synthetic engine oil is better.

Secondly, try to choose winter and summer engine oil. No matter how the temperature changes, the oil can maintain a relatively stable lubricating performance, which has a better protective effect.

Again, choose depending on the situation. If it is new or in good condition, use low-viscosity oil as much as possible, such as 0W-40, 5W-40, and 10W-40, so as to make the flow faster and reduce the wear and tear at startup.

After   *, if it is in the high temperature season or has been worn to a certain degree, it is necessary to choose high-viscosity oil, such as 15W-50, etc. This will help form a thicker oil film, maintain the oil pressure, and reduce oil consumption.

Do not add too much

The amount of oil added is not as much as possible. If it is too much, it will increase the rotation resistance of the crankshaft, reduce the output power, and the excessive oil will burst into the combustion chamber to burn, causing the vehicle to burn oil, emit blue smoke, and increase fuel consumption. The residue after the oil combustion will accumulate on the combustion chamber wall, reducing the space of the combustion chamber, thereby reducing the compression ratio of the engine; at the same time, it will also accelerate the wear of the cylinder and piston, thereby reducing the service life of the vehicle. Therefore, when adding it, it is advisable to keep it slightly lower than the oil dipstick* high mark; in addition, it is necessary to grasp many factors such as the type of oil, the season of oil change, and performance.

No need to add additives

Generally, we do not recommend adding additives to the engine oil. Because its constituent parts are composed of base oil and additives, its formula has been tested and sifted through various tests and then adding additives may backfire. For example, it contains unique anti-wear additives, and the anti-wear properties are tested to be 50% higher than APISM standards. If anti-wear additives are added on this basis, the anti-wear performance may be slightly improved, but it is more likely to happen It is the chemical reaction between the anti-wear additive and the additive, which not only reduces the original cleaning and anti-wear function, but also increases the sludge and carbon deposits, which affects the performance and service life.

filter paper can be distinguished from good and bad

To identify the pros and cons, generally pay attention to a few points: ** is observation. If the oil is clear and yellowish-brown, it means its quality is good; if the color is turbid or emulsified, it means that it contains more water; if the oil has a burning smell, it means that it is prematurely oxidized or mixed with other oils. The second is to check whether there is sediment. The third is that the oil can be dropped on the iron plate or exhaust pipe above 110 ℃, if there is a popping sound, it means that the oil contains moisture. The fourth is to drop the engine oil on the filter paper and compare it with the speckle method. In general, high-quality engine oil should maintain suitable viscosity, neutralization, oxidation stability, wear resistance and corrosion resistance.

There are many fakes on the market. Car owners must carefully identify them. It is recommended to purchase or change oil at designated dealers, major brand gas stations or repair shops.
