What's the difference between tapping and tapping?

Tapping machine is a kind of mechanical processing equipment for processing internal threads, screws or tooth buckles in holes of parts with different specifications, such as casing, equipment end face, nuts and flanges. The tapping machine is also called tapping machine, tapping machine, tapping machine and automatic tapping machine.

Tapping is to screw the tap into the bottom hole to be drilled with a certain torque to process internal threads.

According to the different degree of automation of tapping process

Tapping machines can be divided into fully automatic tapping machines, semi-automatic tapping machines and manual tapping machines.

According to whether the tapping machine drills holes at the same time when tapping

Tapping machines are divided into drilling tapping machines, reaming tapping machines and so on. Automatic tapping machine has the highest degree of automation. When working, as long as the blank of the part is put into the hopper, it can automatically feed, position, clamp, tap and unload. A worker can operate multiple devices at the same time, which has high production efficiency and can significantly save labor costs!

High-quality tapping machine has the characteristics of novel design, reasonable structure, simple use, high degree of automation, convenient use, high efficiency, maintenance-free and high cost performance. All kinds of nut threads machined by high-quality nut tapping have high smoothness and high qualified rate of finished products.

High-precision tapping stroke adjustment is simple, automatic reversing device can freely adjust tapping stroke, shallow holes and low-machining parts with holes can also be easily adjusted, double safety devices can prevent thread tapping damage (broken wires), and double safety clutches are specially set for spindle rotation, up and down, forward and backward, so that the spindle can automatically stop, and reverse tool withdrawal will not damage the tool.

Pitch A and B gears are matched, and the A and B rotating shafts are completely matched with the main shaft according to the pitch, which is vertical, stable, accurate and high in precision. When tapping, the screw runs freely and effortlessly. At the same time, it depends on excellent processed products, which will not cause threads with different thicknesses, and can also tap perfect threads for soft products such as thin plates, light metals and synthetic resins. At the same time, a multi-axis device can be configured for multi-axis synchronous machining, and the production efficiency is greatly improved.

1, the spindle advance and retreat cutter automatically and accurately matches according to the pitch, and will not float when working.

2. The operator's hands can leave the machine freely.

3. It can be used for high-speed continuous cycle operation and is durable.

4. Novices can operate smoothly.

5, high-precision tapping stroke adjustment is simple.

6. Double safety clutch device can prevent disconnection attack.

7. The cooperation of multi-axis tapping machine can produce efficient operation.

split point

(1) The bottom hole of the thread on the workpiece should be chamfered, and both ends of the through-hole thread should be chamfered.

(2) The position of the workpiece fixture should be correct, and the center line of the threaded hole should be placed in a horizontal or vertical position as far as possible, so that it is easy to judge whether the tap axis is perpendicular to the workpiece plane when tapping.

(3) At the beginning of tapping, put the faucet as straight as possible, then tap the faucet hard and turn the wringer. When cutting in 1-2 turns, carefully check and correct the tap position. Generally, when cutting 3-4 threads, the tap position should be correct. In the future, just turn the wrench, and don't put pressure on the tap, otherwise it will damage the thread profile.

(4) When tapping, the wrench should turn around 1/2- 1 2 every turn, so that the broken chips can be easily discharged and the phenomenon that the cutting edge is caught by the chips can be reduced.

(5) When encountering an airtight screw hole, be sure to exit the tap and remove the chips in the hole.

(6) When tapping plastic screws hole, add lubricating coolant. For iron and steel materials, oil or emulsion with high concentration is generally used, and vegetable oil or molybdenum disulfide with high requirements can also be used. For stainless steel, 30 # engine oil or vulcanized oil can be used.

(7) When replacing the rear tap during tapping, screw in the tapped thread by hand first, and then screw it with a wrench when it can no longer be screwed in. When pulling out the end cone after tapping, it is also necessary to avoid rotating the wringer quickly, and it is best to screw it out by hand to ensure that the quality of tapping thread is not affected.

(8) When tapping, the tap and the screw hole should be coaxial.

(9) When tapping, the calibrated part of the tap cannot be completely exposed, otherwise, the teeth will be disordered when exiting the tap.

(10) The cutting speed of machine tapping is generally 6-15m/min for steel; 5- 10 m/min, suitable for quenched and tempered steel or hard steel; Stainless steel is 2-7m/min; Cast iron is 8- 10 m/min. In the same material, the smaller the tap diameter, the higher the value, and the larger the tap diameter, the lower the value.
