A grinding wheel 100 to be dressed is mounted on the workpiece mounting shaft 323.
A controller is connected to the cross slide assembly, the main motor 26, the revolution assembly 31, the rotation motor 324 and the sensor 28.
The utility model provides a full-automatic numerical control emery wheel finisher carries out work according to following step:
step S1: the controller controls the revolution component 31 to drive the rotation component 32 to rotate by a first predetermined angle, so that the preformed surface of the grinding wheel 100 to be dressed (the inclined surface or the curved surface formed on the circumferential side surface or the circumferential side surface of the grinding wheel 100 to be dressed desired by the user) is parallel to or tangent to the circumferential side surface of the dressing wheel 27. Since the axial direction of the dresser wheel 27 is fixed and the first predetermined angle is constant, the controller controls the revolving assembly 31 to rotate by the first predetermined angle. The surface to be machined of the grinding wheel 100 to be dressed before grinding is a.
Step S2: the controller controls the operation of the cross sliding table assembly, so that the sensor 28 senses the grinding wheel 100 to be dressed, and the position coordinate of the grinding wheel 100 to be dressed at this time is taken as a first reference coordinate value. In the present embodiment, the sensor 28 also senses that the circumferential side surface of the dresser wheel 27 faces one end of the grinding wheel 100 to be dressed before grinding, and the position coordinate of the dresser wheel 27 is the second reference coordinate value.
Step S3: the main motor 26 drives the dressing grinding wheel 27 to rotate, and the rotation motor 324 drives the grinding wheel 100 to be dressed to rotate.
Step S4: the controller controls the x-drive shaft 22 of the cross slide assembly to work, so that the dressing grinding wheel 27 gradually moves towards the grinding wheel 100 to be dressed, and the dressing grinding wheel 27 is in contact with the grinding wheel 100 to be dressed, thereby dressing the grinding wheel 100 to be dressed.
In the above step S4, if the preformed surface of the grinding wheel 100 to be dressed is a circumferential side surface or an inclined surface, the angle of the revolving assembly 31 is maintained; if the pre-formed surface of the grinding wheel 100 to be dressed is a curved surface, the controller adjusts the rotation angle of the revolution component 31 according to the pre-set curved surface parameters, thereby adjusting the machining angle of the grinding wheel 100 to be dressed.
Step S5: at intervals, the sensor 28 senses the position of the grinding wheel 100 to be dressed, and uses the sensed position coordinates of the grinding wheel 100 to be dressed as feedback coordinate values. The machining surface of the grinding wheel 100 to be dressed is b at this time.
Step S6: the controller calculates the variation from the surface a to be machined to the current surface b before the grinding wheel 100 is dressed according to the first reference coordinate value and the feedback coordinate value.
Step S7: the controller compares the variable quantity with a preset polishing quantity. If the variation is equal to the grinding amount, the step S6 is performed; if the variation is smaller than the sanding amount, the process returns to step S4.
Step S8: the controller controls the main motor 26 and the rotation motor 324 to stop operating, and controls the x-drive shaft 22 to operate so that the dressing wheel 27 is away from the wheel 100 to be dressed. Therefore, the machining size is fed back intermittently, the measured data is more real, the machining precision is higher, and the full-automatic numerical control is realized.
Step S9: the sensor 28 senses the position of the dresser disk 27, and the position coordinates of the dresser disk 27 at that time are sensed coordinate values.
Step S10: the controller calculates the amount of change in the position of the dresser wheel 27 based on the second reference coordinate value and the sensed coordinate value.
Since the grinding wheel 100 to be dressed and the dressing wheel 27 are worn during grinding, the user desires to know the amount of wear of the dressing wheel 27. Thus, after the grinding is completed, the sensor adjustment cylinder drives the sensor 28 to move away from the grinding wheel 100 to be dressed, so that the sensor 28 senses the position of the dressing wheel 27.
Step S11: the controller subtracts the polishing amount of the grinding wheel 100 to be dressed from the position variation amount of the dressing wheel 27 to calculate the wear amount of the dressing wheel 27. The amount of change in the position of the dresser disk 27 is the sum of the grinding amount of the disk 100 to be dressed and the amount of wear of the dresser disk 27.
This facilitates the user to know the amount of wear of the dresser disk 27 and to replace the dresser disk 27 when the amount of wear of the dresser disk 27 reaches a predetermined value.
