Determination of the movement period of the milling machine spindle

In actual production, the high-quality gear-shaped super-hard grinding wheel has many advantages in performance: high production efficiency: the modified grinding wheel or the tool and the machining workpiece are alternately performed on the same machine tool, which can quickly reproduce the complex surface of precision. On the surface of the grinding wheel or tool; long service life: the grinding wheel can maintain its size and shape accuracy for a long time, the wear amount is very small, the grinding times can reach more than 1000 times, the workpiece product quality is stable, the cost is low; the shaping operation is simple.

The grinding wheel is placed on the workpiece position of the machine tool, and the grinding wheel or tool is randomly repaired, just like machining a workpiece. Low cost of reshaping: no special machine tools are required for the trimming operation, the technical level of the operator can be reduced, the shaving time is short, and the cost is low; the precision of the machined workpiece is high: due to the modification operation and the machining of the workpiece, various process systems The error has been included in the trimming operation, and the workpiece is the reverse process of the trimming. Therefore, the workpiece has high machining accuracy.

The three spindles of the milling machine spindle in turn produce a sinusoidal torque waveform in sequence. It can be considered that there are two basic periodic signals in the milling torque waveform: the milling cutter rotates one revolution per revolution to form a milling cutter rotation cycle (the value is equal to the rotation period of the main shaft), and the interval between the corresponding points between the front and rear teeth forms 1 One single-tooth milling cycle, one milling cutter rotation cycle includes m (m means the number of milling cutter teeth) single-tooth milling cycle. For multi-edge milling cutters, the single-tooth milling frequency is always greater than the milling cutter rotation frequency.

If the cutting process is ideally smooth, the waveform of the milling torque between the two milling cutters is the same. However, the milling torque waveforms between two adjacent single-tooth milling cycles are not necessarily the same, because the geometry of each tooth, the quality of the cutting edge, etc. are slightly different, mainly due to the manufacturing and installation errors of the teeth. A change in the amount of cutting caused by eccentricity. In addition, there are many vibration sources in the cutting process, so in fact, the milling torque signal also contains components of other frequencies.

Air Source Processor

The air source processor is an element that does work through the force generated by the pressure or expansion of the gas, that is, a machine part that converts the elastic energy of compressed air into kinetic energy. Including air filter, pressure regulating valve, oil mist, etc. Start up products are widely used in automatic production of metallurgical Electromechanical, construction industry, transportation equipment, household appliances, light industry, machine tool, medical treatment, packaging industry and other industries. However, because the compressed air discharged by the air compressor cannot be directly used, the compressed air contains a certain amount of water, oil and dust. The compressed air temperature is up to about 140-170 ℃, and some water and oil have become gaseous. Therefore, the purified compressed air must be used to operate the mechanical equipment
