There are many difficulties in processing stainless steel in Anhui. There are many difficulties in processing stainless steel in Anhui stainless steel "target=_blank>, but the main ones are as follows: Reed Switch Fuel Level Sensor, also called float fuel level senosr, it is done by sealed reed switches positioned inside the main shaft of the sensor. A float with built-in magnets then triggers the reed switch relays, generating a potential-signal with resistance, current, or voltage value that increases or decreases according to the fluid level, then give the signal to the gauge via wires, which shows the right level reading by pointer. In the whole reed switch level sensors,the float is the only moving part of the sensor,thereby minimizing potential mechanical failures to get the precision measurement.

1. High cutting force and high cutting temperature This type of material has high strength, large tangential stress during cutting and large plastic deformation, so the cutting force is large. In addition, the thermal conductivity of the material is extremely poor, causing the stainless steel "target=_blank> stainless steel machining to increase the cutting temperature, and the high temperature tends to concentrate in the narrow area near the cutting edge of the tool, thereby accelerating the wear of the tool.
2. Hardened stainless steel "target=_blank> stainless steel and some high-temperature alloy stainless steel" target=_blank> stainless steel is austenitic structure, the work hardening tendency is large when cutting, usually several times that of ordinary carbon steel, the tool is processing Cutting in the hardened area shortens tool life.
3. Easy to stick the knife Whether it is austenitic stainless steel "target=_blank> stainless steel or martensitic stainless steel" target=_blank> stainless steel has the characteristics of strong chipping and high cutting temperature during processing. When the strong chips flow through the rake face, the sticking phenomenon such as bonding and welding will occur, which affects the surface roughness of the stainless steel "target=_blank> stainless steel machined parts.
4. Fastening of tool wear The above materials generally contain high melting point elements, large plasticity, high cutting temperature, which accelerates tool wear, sharp grinding and frequent tool change, which affects production efficiency and increases tool use cost.
In the drilling process, due to the poor thermal conductivity of the stainless steel "target=_blank> stainless steel material, the elastic modulus is small, and the hole processing is also difficult. To solve the hole machining problem of such materials, it is mainly to select the appropriate tool material to determine the reasonable The geometric parameters of the tool and the cutting amount of the tool. When drilling the above materials, the drill should generally use D6W5Cr4V2Al, W2Mo9Cr4Co8 and other materials. These materials have the disadvantages of being expensive and difficult to purchase. The common W18Cr4V standard high speed is adopted. When the steel drill bit is drilled, due to the small apex angle, the swarf is too wide, the hole cannot be discharged in time, the cutting fluid can not cool the drill bit in time, and the stainless steel "target=_blank> stainless steel material has poor thermal conductivity, resulting in concentration on the blade. The upper cutting temperature rises, which tends to cause burns and chipping of the two flank faces and the main edge, which reduces the service life of the drill bit.
