1. Certificates and proofs
Be sure to check the certificate of high-speed drilling, tapping machine products, and other relevant proofs. At the very least, it is necessary to ensure that the high-speed drilling and tapping machine has a production license and will not make some low-level mistakes during use. Only with these relevant proofs can your interests be guaranteed if the machine has problems within the specified time.
2. Manufacturing process
The high-speed drilling and tapping machine requires the bed to be precise and stable when working. Therefore, the high-speed drilling and tapping machine should use a cast body to ensure its processing accuracy and stability.
3. Adjustable range
The general speed adjustable range is from several thousand to thirty thousand revolutions per minute. If the speed is not adjustable or the speed adjustable range is small, then it means that the application range of the high-speed drilling and tapping machine is greatly limited.
4. Price
If the price is ridiculously expensive or unimaginably cheap, it is better not to buy it. The internal structure of the cheap high-speed drilling and tapping machine may not be reliable.
5. Controller
It is generally divided into two categories: one type of controller is only used as a driver, and all its calculations are done by the computer. When the high-speed drilling machine is working, the computer is waiting and cannot perform typesetting.
6. Screw and guide rail
Pay attention to the screw and guide rail of the high-speed drilling machine, which is also an important component. Good screw and guide rail are the guarantee of the accuracy and performance of the high-speed drilling machine during long-term use.
7. Hidden parts
Professionals remind us that we must look at the parts of the high-speed drilling machine that are not easy to check for everyone. Because these parts are not easy to be noticed by everyone, the machine parts are likely to be high-quality imitations or even inferior.
Generally, when purchasing a high-speed drilling machine, a technician must come to the door to unpack and inspect the machine. After the high-speed drilling machine arrives. After powering on, you should carefully check whether the appearance is damaged and whether it is damaged by impact during transportation. If it is intact, check the random accessories of the machine configuration with the random manual in accordance with the contract.
