Description: CNC machining accuracy is determined by what? In nc machining programming, the method and skill used properly, to ensure and improve the machining accuracy of nc machine tool has an important significance. Nc machine tools in the machining accuracy is determined by the position detecting element, Position detection device is by detecting element (sensor) and signal die casting parts processing device, is an important part of nc machine tools closed-loop servo system.
Action is the actual value of detecting the position and speed of the workbench, and send feedback to the CNC device or servo device, so as to constitute a closed loop control. Detecting element are usually performed by using the principle of optical or magnetic detection of position or velocity.
Position detection device according to the detection methods are divided into direct measuring element and the indirect measuring element. For machine tool commonly used while linear movement measuring linear detecting element, known as the direct measurement, posed by the location of the closed-loop control is called full closed loop control.
Measurement precision mainly depends on the precision of the measuring element and is not affected by the precision of machine transmission.
Due to the machine table of linear displacement and rotation Angle of driving motor some proportional relationship, so can use the driver motor or ball screw rotation Angle method of indirectly measuring workbench mobile distance, this method is called indirect measurement.
Constitute the location of the Investment casting parts closed-loop control is called the half closed loop control.
The nc machining accuracy depends on the detecting element and the precision of machine tool feed drive chain. Closed loop nc machine tools machining precision in the very great degree is decided by the precision of the position detection device, numerical control machine tool is very strict requirements for position detecting element, and its resolution is usually between 0.001-0.01 mm or smaller.
What is the advantage of mechanical parts processing heat treatment?
Mechanical parts processing to carry on the corresponding heat treatment process, can let the machining precision of parts and service life is greatly strengthened, this helps to increase hardness, wear resistance and strength of machining parts. Mechanical processing is the use of machine tool equipment to zero.
Carry on the processing of a kind of processing technology. What about how to carry on the heat treatment of mechanical parts processing, mechanical processing of parts processing will accordingly before and after heat treatment process.
1. Remove the internal stress of blank. More used in casting, forging, welding.
2. Improve processing conditions. And so on. Easy die casting parts material processing. Such as annealing, normalizing. Tempering treatment.
3. Improve the comprehensive mechanical properties of metallic materials.
4. Can improve material hardness. Such as carburizing, quenching, etc.
