With the development of smart grid and ultra-high voltage power transmission, the processing level of iron towers has also been greatly improved. In the design of iron towers, large cross-section angle steels and high-strength angle steels are used more and more widely. For angle steels with a thickness greater than 8-20mm, generally drill Hole technology to complete, so the CNC angle steel drilling production line is more and more widely used.
Production efficiency and cost comparison
⑴ From the analysis of actual usage in the current market, the net drilling time of ordinary drilling is about 30 seconds, and the net drilling time of high-speed drilling is about 10 seconds. From the perspective of drilling time alone, high speed cnc angle drilling machine is about It is 2.5-3 times that of ordinary drilling machine.
⑵ In terms of actual use cost: The ordinary drilling machine use tapered shank twist drills. A good quality twist drill can drill about 4,000 holes when the drill bit is well ground. Calculated on the basis of 40 yuan for a drill bit, the average tool loss cost for a hole is about 0.01 yuan/hole. For high-speed drilling, a pair of blades can drill 800 holes on average, but the blade can be used on all four sides, that is, 3200 holes. The price of a pair of blades is about 140, which is equivalent to 0.04375 yuan/hole. In this way, from the perspective of net use cost, the processing cost of a single hole is more than 4 times that of ordinary drills.
The above refers to the use of the ideal state. The quality of the edge grinding of ordinary drill bits will affect the service life of the drill bit, which is a variable factor. For high-speed cnc angle drilling marking line , the service life of the blade is fixed, but the blade must be replaced in advance, and it cannot be replaced after it is worn out. This will easily cause the blade and the drill bit that fixes the blade to be sintered together, and the drill bit will be completely scrapped. , This will greatly increase the cost of high-speed drilling.
price comparison
The equipment price of high-speed drilling is about 2.6 times that of ordinary drilling.
other comparison
Of course, considering the use efficiency and overall cost of a piece of equipment, we can’t just analyze it from the above points. Relatively speaking, high speed cnc angle drilling machine saves one-third compared with ordinary drilling with the same workload in terms of floor area and number of operators.
