Grinding machine speed control method for a three-stage grinding

the beginning, and end of formal phase, beginning up speed rotary grinding, abrasive formal phase constant rotation, the end of the deceleration phase rotating abrasive, characterized in that In the initial stage of grinding, grinding speed artificially control the acceleration from zero increases from slow to fast when the grinding speed is grinding wheel china  raised to half the formal polishing rate, an inflection point of acceleration changes occur, the acceleration of the rotational speed control abrasive The maximum value is coming slowly decreases until abrasive polishing rate of speed reaches formal, abrasive speed acceleration is reduced to zero.
Fixed abrasive polishing using this feature, according to the relative movement between the workpiece grinding track density distribution, the rational design of abrasive abrasive density distribution, so that the abrasive in the grinding process are abrasive wear does not affect accuracy of face , which significantly improves the accuracy of the workpiece face, and to avoid the trouble of dressing grinding. In the plane solid abrasives grinding, abrasive rotary motion is the main movement of the workpiece movement is assisted movement. In most cases, the pressure in the grinding work is floating, the movement of which is unknown. Therefore, to analyze the force on the workpiece to determine the stress state and its law of motion. Take the workpiece grinding system for the separation of the body, the establishment of the workpiece by the  Mounted flap wheel force balance equation, solving the equation of movement of the workpiece can be obtained.
Grinding machine host using speed motor drive, power deceleration system configuration, soft start, soft stop, smooth operation. Through the upper and lower lapping plate, a sun gear, the planetary wheel is formed in the processing of the four directions, the polishing speed of movement coordination, to both upper and lower surfaces of the  Sanding disc efficient operation of the grind. Lower plate can lift for easy loading and unloading of the workpiece. Pneumatic sun gear change to the device, precise control of both sides of the workpiece grinding accuracy and speed. Random with a correction wheel for the upper and lower platens parallel correction error.
Basket Mill Grinding inherited the basket mill grinding and dispersing two processes on one machine, a process to achieve the characteristics, but also can be used alone as a dispersing machine (when the scattered disk in the working position, the grinding basket is not falling) . The material to be ground, and can realize the function of the first dispersed grinding (grinding basket down when working position, the material can be efficient fine grinding).
