Application scope of drilling

Through standardized operation methods, the use accuracy and service life of drilling rig can be maintained more effectively.

2. Scope:

Operational adaptability of radial drilling machine.

Responsibilities:

The operator of the radial drilling machine follows.

Operating rules:

4. 1 Check the slideway oil every day, and idle the spindle for 5 minutes in the morning.

4.2 Before waterway processing, carefully check the drawings, and then process them after confirmation.

4.3 Cross holes often appear in waterways, and attention should be paid to avoid the bit being stuck or broken during processing.

4.4 When drilling the die core, the corresponding rotation speed and feed speed should be selected according to the material.

4.5 Draw a crosshair at the center of the drilling hole required by the workpiece, so that it can be easily identified during processing, and then spray the blue lead marking liquid first.

Underline.

4.6 Fix the workpiece firmly on the workbench. Some small and light workpieces, such as plastic products, can be fixed by hand without fixture.

Just set it up. However, attention should be paid to safety to avoid that the workpiece and the drill bit rotate together, which may damage the cutter and the workpiece, or even hurt them.

To the processor itself.

4.7 Wipe the workbench clean before placing the workpiece, so as to avoid impurities such as iron filings being placed under the workpiece, which will lead to bit deviation.

4.8 Because the radial drilling machine itself has a small workbench, the size of the workpiece should be considered. If the workpiece is too large (the length and width exceed)

250mm) can't be processed on it to prevent the workpiece from slipping or overturning the machine.

4.9 Alignment with the central column: clamp the central column on the chuck, lower it to a height of 1~2mm from the workpiece, start alignment, and move it back and forth, left and right.

Pieces, so that the center column tip is aligned with the crosshair intersection.

4. 10 drill the center hole: loosen the center column, install the center drill, adjust the pulley, drill the center drill generally, and adjust the rotation speed to 1460rpm.

4. 1 1 Turn on the power switch, gently press down the spindle, and drill the center to a depth of about 2mm.

4. 12 Turn off the power switch, remove the center drill after the spindle stops rotating, and select the appropriate drill according to the dispatching list and the drawing requirements.

Head, and firmly clamped on the drill chuck, and according to the size of the tool and the material of the workpiece, choose the appropriate speed and feed.

Turn on the power switch and start drilling. Pay special attention when feeding: be slow when contacting the workpiece for the first time, and it is easy to feed too fast.

The drill bit is stuck by the tool, resulting in tool damage or workpiece damage. Increase the pressure after the feed is normal.

4. 13 In the process of machining, the drill bit should be frequently lifted for chip removal to prevent the tool from being stuck when the iron chips cannot be discharged.

4. 14 Pay attention to whether the tool is abnormal at any time during machining. If there is any abnormality, stop the machine immediately and repair or replace the tool.

With.

4. 15 After the treatment, tidy up the treatment tools, clean them and put them back in their original places, and clean up the environmental sanitation.

5. Preventive measures

5. 1 Before operating the machine, you should have a full understanding of the operating items and methods.

5.2 The operator shall maintain the integrity of the warning label. Do not tear or blacken.

5.3 Unless necessary, no protective cover or door should be opened. No limit switch or safety switch can be removed or

Move it.

5.4 Please use appropriate tools to adjust and maintain the machine, and maintain the machine regularly.

5.5 When operating the machine, do not put your hands or any part of your body on the rotating part of the machine.

5.6 During the whole processing, gloves are not allowed, and work clothes and safety shoes should be worn, especially when iron filings splash during the processing.

Good eye and face protection.

5.7 Appropriate amount of coolant should be added during drilling to reduce the temperature and tool wear.

5.8 When removing iron filings and changing the speed, the spindle must stop rotating to avoid safety problems.

5.9 Pay attention to safety when replacing the speed naughty belt. In principle, change the belt on the big wheel to the small wheel first, and then change the other end.

Change to the right position, high speed to low speed, and low speed to high speed are all applicable.
