When many people buy air compressors, they often pay attention only to the price at the time of purchase, and the costs involved in long-term use are rarely calculated. Practice has proved that the piston air compressor is the most expensive air compressor.
First, save electricity is to save money to a 20 cubic air compressor as an example, the screw air compressor motor power is 110 kilowatts, piston air compressor is 132 kilowatts. It can save 22 kWh per hour, and it can be saved by working 10 hours per day. It can save about 22 degrees per 10 hours and 365 days per year at 80300 degrees. Using 3 years can save more than 200,000 yuan. In addition, the screw air compressor can save more than 60% of electricity when unloaded, while the piston air compressor can only save about 10% of the electricity, work 24 hours a day, 9 hours per sky time, saving 110KW × 9 Hours (60%-10%) = 495 kWh/day, saving 180,000 kWh per year, saving more than 300,000 in 3 years.
Second, to save maintenance costs Screw air compressor maintenance is minimal, as long as the daily maintenance in place, basically do not need to repair. The piston air compressor has many wearing parts and frequent maintenance, which results in large maintenance costs.
Third, the stability of the performance of the screw air compressor only maintenance in place, will not fail. The Piston Air Compressor does not know when it will happen, and delays one day's production. How much will the loss be? The medium and large-sized piston air compressors need to be manually started to release the gas before they start and stop; the voltage instability motor will be damaged and the water shortage will explode. Screw air compressors can operate 24 hours in a row without piston air compressors.
Fourth, the low noise noise of the screw air compressor is very low, can be placed in the workshop, save space. The piston air compressor is too noisy and affects the health of workers.
Fifth, the vibration-free piston air compressor must be reinforced, and the screw air compressor can be placed on a fixed flat surface without reinforcement. Only small vibrations caused by the motor can be neglected in use.
Sixth, non-polluting environment The piston air compressor has a large fuel consumption and is frequently refueled. When it is used for a certain period of time, the bottom part will be black and the screw air compressor will always be clean. The air around the piston compressor contains a lot of oil and gas. The volume of air oil discharged by the screw air compressor is only 1/80 of that of the piston engine, and it is up to the international ISO 8573 standard.
Therefore, most large and medium-sized companies are now purchasing screw-type air compressors.
1.cylindrical milling cutter
Used for processing flat surfaces on horizontal milling machines. Cutter teeth are distributed on the circumference of the milling cutter, and are divided into straight teeth and spiral teeth according to tooth shape. According to the number of teeth and coarse teeth and two kinds of fine teeth. The helical tooth rough tooth milling cutter has fewer teeth, high tooth strength and large chip space, which is suitable for rough machining. Fine-tooth milling cutters are suitable for finishing.
2. face milling cutter
Also known as disc milling cutter, used for vertical milling machine, end milling machine or gantry milling machine processing plane, end face and circumference have cutter teeth, also have coarse teeth and fine teeth. The structure has three kinds: integral type, insert type and transferable type.
3. End milling cutter
Used for processing grooves and step surface, knife teeth in the circumference and end face, can not work along the axial feed. When the end mill has end teeth through the center, axial feed can be provided.
4. Three-side edge milling cutter
Used for processing all kinds of grooves and steps, its two sides and circumference are provided with cutter teeth.
5. Angle milling cutter
For milling grooves at a certain Angle, there are two kinds of single Angle and double Angle milling cutters.
6.Saw Blade milling cutter
Used for machining deep grooves and cutting off workpieces, there are more cutter teeth on the circumference. In order to reduce the friction during milling, there are 15 '~1° auxiliary Angle on both sides of the cutter teeth. In addition, there are keyway milling cutters, dovetail slot milling cutters, T - shaped slot milling cutters and various forms of milling cutters.
