What is the price of a CNC router
Someone once asked me What is the price of CNC router I think I can't answer the question rought now . Because no one about configuration demands, there will be a big difference between prices. you need to tell me you what material you will processing by CNC router machine 。that i cangive you a probable price. CNC roter work in wood and CNC router work in metal have a very different prices. The power ofwood CNC router needed litter than metal CNC router.the price is cheaper. working in diffterent materials will have different prices. the price of a wood CNC router is need 8000$ form Morntech in China .
when you want to kown what is the price of a cnc router online.That you will not get a satisfactory answer,you need asked CNC router manufacturers from different cuntries. you will give me a detailed data.then i will tell you what is the prices of CNC router
CNC Engraving Machine CNC milling comparative analysis between
CNC Engraving Machine CNC milling comparative analysis between high-speed milling
CNC engraving machine in China for the development of one or
two years until recently, have greater development and related
processing plants and the use of units of time, with its keen
eyes staring at the movements of manufacturers, which is as
engraving and milling machine manufacturer is also the host do
not let the real reason.
Of course, as the user to select the appropriate equipment, if
the selection of properly, will not be able to make money but
to make into a bitter situation for the machine to work. So
what kind of machine is a good machine?
We believe that the definition of a good machine like this:
Be able to recover the investment in the short term machine
tool is a good machine.
CNC router tool design life is generally 7 years,
mainly numerical aspects of life prevail, so that the ratio
between money and the money will directly affect your business,
so careful analysis of the functions of selection is a
necessary condition for effective investment .
In foreign countries has had a long term engraving and milling
machine (CNC engraving and milling machine), strictly speaking,
milling engraving is part of the purchase or the purchase of
CNC engraving machine milling machining center is often to ask
their own questions. In addition, the current prevalence of
high-speed cutting machine (HSC MACHINE).
Let us first clear distinction between three models:
1. CNC machine and milling machining center for the completion
of a larger amount of workpiece processing equipment
2. CNC engraving and milling machine used to complete the small
amount of milling, or soft metal processing equipment
3. High-speed cutting machine used to complete the amount of
secondary milling and polishing after the milling reduced to
the minimum amount of processing equipment
In-depth analysis of the structure of the above equipment can
help us make the right choice
First, from the mechanical point of view of analysis of
Machine tools, machinery is divided into two parts, moving
parts and non-moving parts. Workbench, skateboards, etc.
cruciferous Taiwan moving parts, bed base, column and other
non-movable parts.
1, CNC milling machining center
Non-mobile part of the steel requirements very well
Moving parts of a very good steel requirements
Benefits: Can be re-cutting;
Disadvantages: As the mobile part of the equally large at the
expense of machine flexibility, and quick for the small part of
the feed powerless.
2, CNC engraving machineand milling machine
Non-mobile part of the steel requirement of good
Gang of moving parts should be flexible for the former premise,
as far as possible lighter, while maintaining a certain degree
of rigidity.
Advantages: can be too narrow for the processing, machining and
high accuracy. For soft metals can be high-speed machining;
Disadvantages: poor it is not possible because the steel for
re-cutting.
3, high-speed cutting machine tools
Non-mobile part of the steel requirements very well
Requirement of steel moving parts is better, and lightweight as
possible.
Advantages: small amount of cutting can be carried out (for
example, φ10 of the flat knives in general, for 45 steel (300)
deep depth to 0.75 is better);
Disadvantages: can play under the correct use of efficient, low
cost, so polished into a very small amount. Improper use
immediately would make the tool waste piles.
How do the above mechanical light, rigid requirements of a good
contradiction lies in the mechanical structure on the martial
arts.
1, the bed body with the use of high and low reinforcement mesh
architecture, ranging from direct use of honeycomb-like
structure connecting the inner hexagonal wire mesh
2, extra-wide columns and beams, we all know, gantry-type
structure because of its excellent symmetry and excellent
rigidity are high-speed cutting equipment manufacturers have
been used as the preferred structure.
3, for the moving parts are marked with the CNC milling
difference is widening a lot of guides and the slide distance
of the question, to overcome the negative torque problems.
4, ranging from materials commonly used in terms of m Hannah
cast iron, cast iron that is nurtured, in the pouring molten
iron when adding a certain percentage of silicon (Si) thus
changing the internal structure of iron to make it more
resistant to stamping, a significant improvement on the rigid .
5, the rigidity of machine is mainly used to overcome the
moving parts moving at high speed when the powerful impact of
the non-moving parts, so rails, screw required some rough and
enhance the connectivity part of the rigidity.
Second, from a numerical point of view of analysis of
1, CNC milling machining center CNC system requirements for the
speed in general, about O ~ 8000RPM spindle speed.
2, engraving and milling machine. Require high-speed CNC
system, spindle speed of about 3000 ~ 30000RPM.
3, high-speed cutting machine tools require high-speed CNC
system and excellent servo motor characteristics, spindle speed
1500 ~ 30000RPM around.
Third, the programming software to analyze
From a software perspective, CNC milling machining center,
high-speed cutting machine engraving and milling machine can
use the standard CAD / CAM software, such as: Mastercam
Cimatron PE UG and so on.
Milling machine is usually better to think that Cimatron
tool path, the new version of the software tools at all times
fully elegant to cutting the amount of uniformity, particularly
in the work of a moment out of a knife into the speed and
sleek, as well as to follow the difference in the inflection
point of the algorithm problem (following Error), so that the
results, and even paste graphics into the design, CAD part of
the extensive use of just an intuitive three-dimensional solid
modeling, such as Solidworks, etc. and then into the CAM
software, such as through the IGS processing.
But do not worry, CAD / CAM of the growth rate much higher than
the pace of development of CNC machine tools.
4, Tool Storage Tool Automatic Tool Changer and automatic
requirement for
Machining Center is a decent term, processing center in order
to complete a variety of processes in the automatic state of
numerical control equipment, primarily for some fixed large
quantities of production operations, if we are processing a lot
of holes, teeth box, but also to every day to do about the same
(a minimum volume of 200 or above) then it must select
processing center for the mold industry and small batch
production units do not just turn on the machining center, as
seen too many manufacturers to buy machining center, CNC
milling machine to use when the use of a knife base pairs of
the cost in terms of numerical control system is very simple,
but the spindle and tool libraries, air compressor and a
variety of shank, etc. will increase the cost and therefore the
difference for a piece of equipment more than 10 million yuan,
and the programming staff should be clear-headed. Otherwise,
tragedies occur, the problem is relatively increased a lot.
Efficiency of how the same species for the production of less
than 1, 200 of the workpiece try not to use the processing
center, efficiency is too low.
What is a good way to improve efficiency, do not use a knife
library, they will not cause an artificial ATC error, only the
fully automated system on the knife, knife up a loaded, a
button, machine tool automatic tool, direct processing, the
error in the 0.001 ~ 0.003μm in, and automatically change over
time, can not be a bit slower efficiency. If the processing
center nor the automatic machine tool equipment base and non-
knives, but the knife machine automatically compared to the
efficiency of the practice, which is much higher than the
former. Please note that good and automatic knife instrument
the price of the best brands, such as (Marposs) However, one
million per, and are less likely to damage, this analysis, for
a lot of the domestic labor force mold processing, as well as
small quantities of industrial parts machining If you give full
consideration to the value of a certain use of capital
equipment, machining centers should not be used, In addition,
the domestic manufacturers knife library basically a lot of
problems. Imports also quite expensive. (BT40 tool magazine of
10 will not be less than 10 million yuan).
5, high-speed cutting equipment, the views of
Smart processors will certainly take into account a lot of time
machine preparation time and personnel losses caused by human
factors, and we do not always remember to remind them in this
regard. And we have to do is how the processing time from the
machine to give them a higher processing efficiency, as well as
polished as much as possible to lower their time. Even zero
grinding. High-speed cutting equipment, its debut is to allow
processors slammed cardiac events. Let us not consider the high
cost (about 1.5 million), single from the use of speaking, I
think it must be this old saying: Some people are concerned it
is a savory meat, for others is a highly toxic poison in terms
of The Japanese and European efforts to publicize the benefits
of high-speed cutting and makes the use of their equipment. Of
course, some impractical approach. CNC machine tool industry in
the eight years of actual combat experience tells me that their
costs should be 60 to 70 million. Such a high profit margins is
to allow me to see them nature. The gross domestic numerical
control machine tool should be (30 ~ 40%) between. This is a
reasonable, honest profit. If you are willing to maintain their
high profits at the same time I would like to impossible to
earn more money. Should also consider the after-sales service
and so on. I can not believe that their services can be 1 to 2
days to solve all problems. Because of our existing technology
also can not be achieved "solid fax."
From the revitalization of the national industry point of view,
should support the development of domestic machine tool
factory. The nature of high-speed cutting is to walk the length
of the tool has completed in a short time. As we all know:
Distance = velocity × time
Determine a fixed cutting tool: longer means making a profit,
increase the speed is equivalent to the time improvement.
High-speed cutting machine itself because of the current use of
the tool spindle and the restrictions it is not necessarily a
good decision, the current common practice abroad, is the first
device does not use high-speed cutting, while the second or
third station may consider such a machine.
Successful practices, such as:
A profile milling most of cutting the amount of the completion
of (re-cutting) and left at the 2 ~ 3mm of the machining
allowance, cutting the amount of the remaining high-speed
machine tools quickly, so doing a lot of advantages:
1) re-cutting machine tools a lot of low processing fees
2) processing a large amount of high accuracy is not easy to
achieve
3) Cutting Tools cheap
4) After transferred to high-speed cutting, because the
processing of the object is close to forming, so the first
volume of a very uniform cutting knife
5) forming quickly and accurately
6) avoid too much polishing to meet the exact size
7) The tool although expensive, but time is short, cutting the
amount of small, very good cost performance ratio
8) Many of the nuances, such as small-degree angle guide and
detailed processing in one step rather than to help spark
9) Excellent surface finish (mirror effect)
It is evident, and equipment and coordinating gain an upper
hand because it is the remaining volume of 2 ~ 3 mm so the work
done two calibrated XY stage G54's bumpers to complete the
workpiece clamping problem, and for cutting small amount of the
workpiece directly in high-speed machine is complete.
6, to discuss the issue spindle
For the CNC router machine center because they
require low-speed large torque, it must be a transmission main
shaft to the gear ratio to improve low speed torque accuracy is
inevitable, so is unlikely with a small radius tool.
For carving and milling machine spindle is to work in the 2 ~
30000 RPM can work, turning the general accuracy of about 2 μ,
otherwise the whole phenomenon Duandao very serious, they must
be electric spindle, that is, motor and spindle are one. For
high-speed cutting equipment is concerned, demand Built-in
spindle, but also at low speed when the torque need to use a
certain oil-water cooler to keep the temperature constant
spindle spindle power to 7.5 ~ 8KW more speed to more than
25000RPM
