Exhaust-driven turbochargers can rotate more than 300,000 rpm per minute. They compress a large amount of air for combustion, making the engine run cleaner and more efficient.
For a normal driver, the turbocharger allows them to sacrifice the pleasure of driving in order to improve fuel efficiency. For diesel car owners, the main benefit of the turbocharger is that it meets the emission limit of carbon dioxide and nitrogen oxides, and maintains the high performance of the car. Compared with naturally aspirated cars, turbocharged diesel engines Can increase fuel efficiency by up to 40%. In addition, Hyundai Motor does not always install only one turbocharger, but can install up to three.
From a larger perspective, turbocharging is a key factor in increasing vehicle power density—in other words, allowing smaller engines to output more power. A large automaker expects that in the next 10 years, the average US engine displacement will rise from 3.6 to 3.0 liters, while in Europe it will rise from 1.7 to 1.5 liters. With the growing demand for smaller and more efficient engines, approximately 85% of new European light vehicles may be equipped with turbochargers by 2020.

Rough milling
The Sandvik Coromant M612 is a face milling cutter specifically designed for rough milling of turbine expander housings. The compact and rugged M612 body is ideal for applications where vibration is easy. It uses a round double-sided insert with a positive rake pattern that ensures high metal removal rates while ensuring a smoother cutting process. The blade has 12 cutting edges, 6 on each side, and a depth of up to 3 mm, enabling a lower cost per piece.
Blade design
The surface of the M612 indexable insert is fitted with the same shape of the blade groove to ensure the accuracy and repeatability of the blade positioning.
Threaded hole
The multi-purpose CoroDrill® 460 high performance drill and the CoroTapTM 300 spiral groove tap also provide an efficient hole machining and tapping solution for the tool package.
Turning operation
CoroTurn® HP turning tools accurately spray coolant through fixed nozzles, which greatly increases chip breaking performance, process safety and productivity. When machining austenitic stainless steels at 100ba coolant pressure, CoroTurn® HP has a tool life that is up to 7 times longer than conventional tools.
The turbine casing of the turbo-turbocharger must be able to operate at temperatures ranging from 850 degrees Celsius to over 1,300 degrees Celsius (1,562 to 2,372 degrees Fahrenheit). Operating at these extreme temperatures requires high wear resistant stainless steel or advanced cast iron materials.

Base Seals are an important component used to seal machines and equipment. They are usually used to prevent liquid or gas leaks and protect machines and equipment from dust, pollutants, and other external elements. Base Seals mainly include rubber seals, oil seals, mechanical seals, O-rings, U-rings, V-rings, X-rings, and other types.
Rubber seals are a type of seal widely used in various machines and equipment. They are usually made of rubber materials and have characteristics such as wear resistance, corrosion resistance, high temperature resistance, and low temperature resistance. Rubber seals are mainly used to seal liquids or gases in machinery and equipment, such as automotive engines, water pumps, pipelines, fans, refrigeration equipment, etc.
Oil seal is a type of seal specifically used to seal lubricating oil. They are usually made of rubber and metal materials and have characteristics such as wear resistance, corrosion resistance, and high temperature resistance. Oil seals are mainly used in equipment such as automotive engines, industrial machinery, water pumps, and hydraulic systems to prevent lubricant leakage.
Mechanical seals are advanced seals used to seal machines and equipment. They are usually made of metal and ceramic materials and have characteristics such as wear resistance, corrosion resistance, high temperature resistance, and low temperature resistance. Mechanical seals are mainly used in high-speed rotating equipment, such as centrifugal pumps, compressors, fans, centrifugal separators, etc.
O-ring is a common sealing element, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. O-ring is mainly used in fields such as automobiles, machinery, and electronic equipment.
A U-shaped ring is a sealing element with a U-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. U-rings are mainly used in hydraulic systems, pneumatic systems, automotive braking systems, and other fields.
A V-ring is a sealing element with a V-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. V-rings are mainly used in fields such as automobiles, industrial machinery, and hydraulic systems.
7. X-shaped ring
An X-ring is a sealing element with an X-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. The X-ring is mainly used in hydraulic systems, pneumatic systems, automotive braking systems, and other fields.
