FRT-3800 stone edge polishing grinding machine for exporting

After the machine tool arrives at the installation site, first check whether the appearance of the machine tool is in good condition, whether the matched parts are complete, and the foundation of the installation site must be solid. The foot of the machine bed is equipped with four M16 adjusting building bolts. Before balancing, place the four iron plates attached with the machine under the bolts, which shall be based on the working surface. Carry out balance correction, and it is allowed to be less than 1 / 500. After correction, lock the fixed nut of adjusting bolt. And fixed foot bolt, the best use of concrete pouring fixed foot, which improves the stability of machine tools, prolong the service life plays a great role.

Before using the machine, add enough lubricating oil to the horizontal track, and check whether the vertical track, lifting track and lead screw are clean and lubricated. Whether the cooling water is unblocked, whether the wires are damaged, and whether the safety precautions are implemented.

After the preparation before commissioning, first press the grinding head start button, the grinding head rotates according to the direction indicated, and pay attention to whether the operation is normal, set the stroke switch, press the left (right) feed button, the grinding head starts to move horizontally, observe whether the operation is stable, and then debug the automatic, semi-automatic, feed fast, slow and other functions one by one. When the automatic button is pressed, the grinding head will automatically return to the specified position as a result of the action of the travel switch. When the semi-automatic is used, the grinding head will automatically stop running when it reaches the positioning position. If the left (right) feed button is pressed again, the grinding head will run in the opposite direction - the grinding head will work in one direction.

After debugging and observation, the machine tool operates normally, and users can start to work at ease.

1. Loading and unloading of grinding wheel

The machine is equipped with 6 cone shafts for grinding wheels for customers' standby, and a special handle for loading and unloading cone shafts. In order to ensure safety, the interlock device is designed. When the handle is hung at a specially designated position after loading and unloading cone shafts, the machine can be started, otherwise the machine cannot be started. First remove the special handle, insert it into the loading and unloading slot on the upper end of the grinding head spindle, and press the other hand of the handle to move the taper shaft of the grinding wheel to the taper hole of the spindle for a certain distance, and then turn it about 30 degrees to the right. The small round pin on the top of the taper shaft has been automatically inserted into the pull rod in the spindle. At this time, open the loading and unloading handle, and observe whether the big round pin on both sides of the outside of the taper shaft has been inserted into the positioning slot If it is not clamped in, press the handle again, turn it slightly, and release the handle. The order of disassembling and assembling the grinding wheel is opposite to that of installing.

2. Grinding of straight line

The straight line grinding is relatively simple. The operator will put the board on the work table, move it to a certain distance, straighten the direction, fix the size (set the distance of the stroke switch), and set up the grinding wheel to select the desired shape in advance, then adjust the lifting slide plate, make the grinding wheel top and lower the edge of the board, start the machine tool, adjust the longitudinal slide board, and control the feed quantity. To achieve the best working condition.

3. Grinding of curve

When grinding the internal and external curves, first remove the two zigzag fixed bolts on the longitudinal slide, then the process will be bent and moved. When grinding the external curves, the two handles of the operator will be informed by the grinding head handle, and the grinding will be carried out along the curve () of the plate. The process proficiency of the operator will directly affect the quality of the finished products of the curve. If it is a line with large grinding curvature, it should be placed under the specially ground plate Our company randomly configures our wooden frame to raise the plate so as to avoid the fixed bolts at the bottom of the grinding wheel from touching the working surface. Grind the inner hole. You need to put a wooden frame under the hole. You can grind the inner hole by grinding the outer edge. In general, grinding a forming line (straight line or fancy line) requires four processes: diamond wheel, rough grinding wheel, fine grinding wheel and polishing wheel. This machine has the advantages of quick loading and unloading and convenient wheel changing.
