A small diameter precision stainless-steel tube is also known as a stainless steel capillary tub. It is used widely in precision instruments, mechanical parts, fishing tackle, industry, and other fields. Sometimes it must be drilled. So how do you drill a small precision stainless-steel tube? The opening can be divided into four types: manual drilling, electric drilling, hydraulic punching, and automatic drilling. Let's now look at the four methods of opening:
1. Drilling with an Electric Drill
A variable speed hand drill can drill holes. Stainless steel is strong and can stick to knives easily, so drills must have higher hardness and better finish. The drill point angle is greater than the normal drill. Cooling should be adequate (between 130-135°). Carbide drills are more efficient than traditional HSS drills for drilling.
2. Hand stamping
Before drilling, place the machine on the workbench. Turn the machine wheel slightly to check its working condition. Make sure to check for foreign objects near the punch and lower dash, and if necessary, remove them. Add grease to the contact point between the machine guide bush's top and the mold base. To stamp the small diameter precision stainless-steel pipe, place it in the appropriate location. Next, turn the handwheel counterclockwise. Once the piercing has been completed, you can stop turning the wheel using your left hand and gently pull the perforated precision Stainless Steel tube outwards with your right hand.
3. Hydraulic punching
Connect the oil pump to the work head using a quick coupler. Next, choose the appropriate upper and lower molds and install them first. To make the screw work, first move it to a specific position. Next, place it in the bottom mould. Install the small diameter precision stainless-steel pipe. Next, tighten the oil return screws of the oil pump. Move the handle to the end and loosen the oil return. The wiper washer must be placed between the pipe and the tripod when punching thinner stainless-steel pipes. Otherwise, it will stick to the mold.
4. Automated stamping
Move the precision stainless-steel capillary first to the scanning area in the machine chamber. The camera will scan the image and then send the signal to the control component. The X-axis, Y-axis, and the Starter Part are activated after the movement is complete. The solenoid valve then controls the cylinder to perform the punching action. The whole process is completed quickly, efficiently, and accurately by the machine printing positioning holes.
