“Design and manufacture a wireless transceiver that performs mixed transmission of digital-analog signals on the same channel. Among them, the digital signal is composed of a set of 4 numbers from 0 to 9; the analog signal is a voice signal with a frequency range of 100 Hz to 5 kHz. Using wireless transmission, the carrier frequency range is 20~30MHz, the channel bandwidth is not more than 2...
According to the stainless steel parts processing company, stainless steel is hard and will generate a lot of heat during processing, which will damage the tools. It often makes many people feel headaches. By prescribing the right medicine, everything becomes easy.
Tungsten-cobalt alloy has good toughness, cutting is light and fast, and chips are not easy to stick to the tool. It is especially suitable for rough machining with large vibration and stainless steel turning with intermittent cutting. Our commonly used cutter heads are W10, W20, YW2. The material of the tool shaft is 45# steel quenched and tempered, which can strengthen the strength and rigidity.
The stainless steel parts processing company stated that the tool rake angle of 15°~20° is the most suitable for the treatment of stainless steel cutting heat. When rough machining, a smaller relief angle should be used first; during finishing, because the hardening of the material is prone to occur, the relief angle is about 6°~8°. Normally, the relief angle should be appropriately larger than when processing ordinary carbon steel. The angle of blade inclination is usually 15°. For fine turning of the outer circle, fine turning of the hole, and fine planing of the plane, when the amount of knife is relatively small, a large blade inclination angle of about 50° should be used.
According to the stainless steel parts processing company, the cutting speed should not be too fast. The linear speed is 60~80 m/s. The amount of knife is 5-6 mm each time. The feed rate can be determined according to the smoothness requirements. A few threads to half a millimeter mm/r is appropriate. Never treat stainless steel in the same way as ordinary carbon steel
Cooling lubricating fluid can reduce the cutting heat and cutting force during the cutting process, which not only prolongs the service life of the tool, but also ensures the smoothness of the product. Emulsion can be used, but for products with high requirements on finish, special cutting oil for stainless steel should be used
