BSH square grinding machine is a special equipment for grinding the small cylinder of Nd-Fe-B magnetic material. It is rotated by the diamond grinding wheel and the guide wheel in the main shaft.
The coarse mill is paired with the fine mill
First, the main technical factors of machine tools:
1, the largest processing size: square grinding round Phi 10mm, cylindrical rough grinding round Phi 14mm, Phi 8mm below can automatically feed
2, minimum processing size: Phi 1.8mm
3, processing length size: 10- 50mm (manual feeding); 10- 33mm (automatic feeding)
4, processing speed: continuous manual feeding (600mm, -1000, mm) /min
5, workpiece tolerance range: rough grinding, non circularity + 0.04mm
6, the guide wheel table lateral travel 80 mm, scale division range 0-100, each grid is 0.02 mm, each turn is 2 mm.
7, the guide plate, the next stroke: 25mm
8. Main motor (AC380 * 50Hz) 1.5KW * 1410r/min; vice motor (AC380 * 50Hz) 0.75KW * (0-1200) r/min adjustable
Two. Parts of machine tools
1. Lathe bed
2, grinding wheel rack
3. Baffle (alloy sliver welding)
4, baffle rack
9. Cooling pump
10. Cooling tank
11. Feeding rack
12, electrical controller composition
Three, machine tool working system
The main motor drives the diamond grinding wheel directly, the speed is about 1450 revolutions per minute, and the speed regulating motor is used
Drive the guide wheel to rotate, the speed of the guide wheel can be processed according to the finish and work speed of the finished product
Coordinated regulation. The size and accuracy of the machined workpiece are driven and lowered by the guide wheel from the carriage
Board top down adjustment control.
Four, operation procedures
1. Please read the instructions carefully before use.
2, the electrical control method of operation: first, open the switch; two, start the main motor; three, start the motor side, open the switch and then the excitation regulator, the rotating button from 0 rotation to the required speed, stop, speed and excitation switch must turn off the switch, in order to burn the excitation coil.
3, first check the square shape of the product to be processed, and the square dimension tolerance shall not be more than 0.08mm.
4, according to the processing size, adjust the distance between the two wheels, and then adjust the plate to the appropriate position, but must be in the center of the two wheels, and finally the fastening screws locked.
5, V shape material frame, about to alignment, two wheel center, up and down slightly below the center of the two wheels.
6, the guide wheel often trimming, dressing method, the tailgate removed, the two wheels symmetrical since grinding, and until the self-study flat.
7, in order to increase the life of artificial diamond, rough grinding, please sub two times grinding.
8, because grinding is the use of saponification cooling liquid, please use after cleaning machine tools, and good rust proof oil, so as to avoid rust and other faults.
Five. Cooling system uses saponification oil and water for cooling
The machine bed slideway system uses the ordinary mechanical oil lubrication.
Six, the electrical structure and principle (attached)
380V three phase electric line is connected to the wire plate, wire, power line interface and reliable, should take the knife switch. When the line is connected, please press the motor start button, pay attention to the spindle rotation direction, and use the spiral fuse and overload protection device in the electrical control circuit.
Seven,installation and adjustment of machine tools
After positioning the machine tools, adjust the foot of the machine and adjust it according to the level. Then put the cooling oil tank, connect to the power supply, you can debug.
Eight, size: 890mm * 750mm * 1200mm; body weight: About 500kg
