With the development of smart grid and UHV
power transmission, tower manufacturing level is also greatly improved. In the
design of the tower section angle steel and high strength steel angle is used
more and more widely, according to the requirements of the standard of
GB2694-2010, thickness greater than 8-20mm (angle and material), the angle, the
original NC hydraulic angle punching production line processing technology, we
must use the drilling process to complete, such CNC angle drilling and
production line is more and more widely.
Jinan Supertime Technology Co., Ltd. in 2007
launched a JX2532 CNC angle drilling production line, launched in 2009 JX2532F
CNC angle high speed drilling production line, launched in 2012 JX3540D CNC
angle high speed drilling production, 2014 launch JX3635F numerical control
angle steel high speed drilling production line, has been widely used in the
market.
Production
efficiency and cost:
From the current
market actual use situation analysis comparison, same cutting 20mm thick steel,
common drilling net drilling time about in 30 seconds or so, a high-speed drill
net drilling time in 10 seconds or so, simple from the drilling time see
high-speed drill is about 2.5-3 times that of ordinary drilling. That is to
say, it has a great advantage to compare the high speed drill from the
production efficiency.
The actual use of
cost: ordinary drill taper shank twist drills, for a bit to drill many holes,
now there is no market is clearly a statistical data, by consulting the user
probably derived the following conclusions, a relatively good quality of twist
drill, the drill worn ideal state, about to 4000 holes. According to a drill
bit 40 RMB to calculate the average cost of a hole tool loss of about 0.01 RMB
/ hole. For high speed drilling, a pair of blades can be drilled on average 800
holes, but the blade is four faces can be used, is the 3200 hole, a pair of
blade price is about 140, equivalent to 0.04375 RMB / hole. In this way, the
processing cost of a single hole is more than 4 times as high as that of a
common drill.
Above refers to the use of the ideal state, for
the common drill bit edge grinding will affect the life of the drill bit, which
is a variable factor. For high speed drilling, and the service life of the
blade is fixed, but must be replaced ahead of the blade, can't it wear the
change again, so it is easy to make blade and a fixed blade bit sintering
together, the drill completely scrapped, and a drill handle cost at least 2500 RMB
will greatly increase high speed drilling cost.
Of course, considering, comprehensive cost
efficiency in the use of a device can not only a few points from the above
analysis, relatively high-speed drilling in the area, the operator number of
than the same workload of ordinary drill to save one third of.
