Put the metal parts into the solution of NaOH, NaNO2 and other potions. At a certain temperature, the parts will react chemically to produce a thin blue (black) oxide film. Blackening can be divided into normal temperature blackening and high temperature blackening. Generally, the surface oxide film of normal temperature blackening is relatively thin, and the effect of secondary blackening is better. The blackening treatment temperature at high temperature is about 135 ° to 155 ° and the blackening effect is also the best. What Is Blackening For Metal? Metal blackening is a common CNC surface finish treatment process. The purpose of blackening is to prevent rust on the metal surface. There are two kinds of metal blackening: alkaline heating blackening and normal temperature blackening. The problem of checking the antirust effect may occur due to process problems in normal temperature blackening. How Do You Blacken Metal? The process flow of metal blackening is as follows: Degreasing: Boil the parts in degreasing solution for 20~30 minutes at 80~100 ℃. Cold water cleaning: rinse with flowing clean water. Pickling: wash with hydrochloric acid solution at room temperature for no more than 30 seconds. Blackening (put the blackening liquid in a stainless-steel container and heat the bottom with an electric furnace) Water washing: wash with flowing cold water or warm water for 30-60 seconds. Boiling water cleaning: 2-5 minutes. Saponification treatment: temperature 80~90°, time 2-3 minutes. Immerse in oil: immerse in transformer oil or spindle oil at about 80° for 1-3 minutes, and then the finished product is cleaned.

The main difference between them is that the complexity of processing parts is different. The range of five-axis processing is wider than that of four-axis processing. At the same time, the cost of five-axis processing is also higher. Generally, it is more suitable for use in the product sample stage. Five-axis processing includes Aeroengine Blades, shells, automobile, and shipbuilding industries. 5 axis CNC service is usually very suitable for extremely complex and strong parts that must be cast, such as parts with high relative accuracy and parts that cannot be clamped twice. Four-axis machining parts are usually parts that cannot be machined by ordinary three-axis CNC, such as turbine, vortex rod, fan blade, wave wheel, and other curved surface and groove machining. Applications of 4/5 Axis CNC machining The 4axis CNC center can adapt to the parts processing in the mold industry, automobile parts and wheel hub processing, automatic machining, and 4 axis machining is also widely used in aerospace and other fields. Industrial upgrading, intelligent manufacturing, unmanned factory and automatic assembly line are the most direct requirements of the processing and manufacturing industry for high-end machining machines. The application scenarios of four- axis and five-axis CNC processing are as follows: Aerospace industry: from Boeing 787 Aircraft propeller parts (titanium alloy or polymer materials), turbocharger (metal) parts, gearbox shell processing (casting), hydraulic system and component processing (casting), electromechanical component parts (metal), engine component processing (metal), landing gear assembly (integrated molding), UAV components (carbon fiber shell, propeller), etc. of Airbus A380 large aircraft.

TIMKEN LM48548/LM48510 Inch Taper Roller Bearing Weight 0.259 Kgs LM48548/LM48511A In Stock LM48548/10 TIMKEN Tapered roller bearings utilize conical rollers and raceways, arranged so that the rollers and raceways meet at a common apex. The rollers are guided by contact between the large end of the roller and a rib on the inner ring. This provides high capacity for radial and single thrust loads. Koyo pioneering efforts in developing crowned rollers have resulted in greater load-carrying capability and longer bearing life. Crowned rollers under load distribute stress equally along their full length of contact with the raceways, thereby eliminating stress concentration at the roller ends. This design concept also compensates for minor misalignment between shaft and housing bore and deflection under load, thereby reducing stress concentration.
