Step 1, Turn On to Start.

1. Turn on the power of the control computer and monitor, and start the CNC routing software

2. Press the power switch.

3. Turn on the spindle motor cooling water pump and check the cooling water flow.

4. If the machine is turned on for the first time today, depress the handle of the lubricating oil injector once, and add lubricating oil to the lubricated part.

5. Perform the mechanical origin return operation in the software, and eliminate possible collisions before the operation.

6. Manually move each feed axis 1 to 2 back and forth within the full stroke.

Step 2, Workpiece Clamping.

1. Place the cushion material in the center of the workbench.

2. Place the workpiece to be processed on the mat.

3. Use at least 4 sets of pressure plates to fix the workpiece on the worktable.

4. Check whether the workpiece is clamped firmly.

5. Find the edge and set the workpiece origin:

a. Move the spindle along the feed axis that accurately sets the origin until the tool will touch the workpiece.

b. Start the spindle.

c. Switch to single-step movement with step size 0.01mm or 0.05mm.

d. Move in one step until the rotating tool touches the workpiece. At this time, a slight noise will be heard.

e. Zero the workpiece coordinates of this axis or record the current machine coordinates.

f. Move the axis to move the tool away from the workpiece, and pay attention to confirm that the moving direction is correct.

Step 3, Tool Changing.

1. Disconnect the power of the routing machine to ensure that the spindle motor stops.

2. Move the spindle to a position where it is easy to change the cutter, and place the soft material directly under the cutter to avoid damaging the cutting edge when the cutter falls.

3. Fix the spindle with a small wrench, and turn the chuck nut clockwise (viewed from top to bottom) with a large wrench, taking care not to hit the cutting edge with the wrench.

4. If you need to replace the router chuck, unscrew the chuck nut and replace the router chuck to remove foreign objects in the router chuck and chuck nut.

5. Check whether the cutting edge of the router bit to be clamped is intact.

6. Install the collet and nut on the spindle.

7. Insert the router bit to be clamped into the hole of the router chuck, as far as possible according to the actual situation (but the cylindrical part of the bit cannot be fully inserted), and tighten the nut by hand. This step cannot be reversed from the previous step: do not insert the bit before installing the nut on the spindle.

8. Tighten the nuts with two wrenches, being careful not to use too much force, and also being careful not to hit the cutting edge with the wrench.

9. Confirm that the wrench is away from the spindle, and turn on the power.

10. Set the router bit again and set the Z coordinate of the workpiece origin.

Step 4, Start Programming.

1. Confirm the following work:

a. The router bit is firmly clamped.

b. The workpiece origin is set correctly, especially the Z coordinate of the workpiece origin after tool change.

c. Workpieces are clamped firmly.

d. The NC program is loaded correctly.

2. Adjust the feedrate override to about 30% in the CNC software and start the CNC program.

3. After confirming that there is no abnormal operation, adjust the feedrate override to the normal value.

4. Someone must be on duty during operation.

Step 5, Shut Down to Stop.

1. Return to the mechanical origin.

2. Remove the router bit and the chuck nut is allowed to stay on the spindle.

3. Turn off the CNC machine kit.

4. Turn off the computer, this step can not be reversed with the previous step.
