Future of the workshop – Industry 4.0
Last exhibitions show the grandest promotion of Industry 4.0 and digital manufacturing. What it means for the workshop?
Till today industry made a big grow with digital solutions – numerical systems and CNC controls offer flexible possibilities not only for standard control of the machine during the working cycle but exchange of the information to control the machine in global chain of the workshop. Yes, all additional things have nothing for small workshop but imagine what means to develop the digital chain for the big factory!
Parts with the passing of the stages with the barcodes and control of each location of the part, flow management, machine status management, global network for engineers and technical specialists for import and export of parts, personnel control, cloud technologies – all the things for develop most modern factory which you could imagine.
Industry 4.0 is closely connected with the Internet, wireless data transfer technologies, clouds and digital solutions. Sure thing any industrial computer can offer network data transfer but the question is not to operate the machine but to create the virtual factory with the possibility to manage everything only with your display from any place of the world.
Most of manufacturers today offer the advantages of the Internet service and diagnostic but in general today this is the one future only for the global network connection. Modern drawings are made in 3D CAD but are situated only inside the network of the factory or the single computer of the engineer.
The future offers more global solution with including of the manufacturer, customers and producers together with the machine, flow and production activities in global chains where the customer can control the flow of his order, manufacturer can control the machines, automatically orders customer can send directly to the machine for production, global control from the management side and as the result - the clean and very effective relations between all the parties with much less involved people but the global transfer of the information. People there are not the workers but the operators of manufacturing world and who knows, probably involved also in new generation social networks dedicated to the new material flows.
Punching tool systems - Multitool
Everybody who looks for the first CNC punching machine to proceed with sheet metal has the question has the question what punching tool system he should use.
We will not speak about all the details because this is the role of the punching machine manufacturer. Anyway it is important to know some simple things – the main point for tool system of the punching machine is the specification of your production. Let’s explain. The simplest punching machine with CNC has one and only one station where you can put Multitool head. This is the most economy solution but with serious limits for production – for example you will have 8 tools with 24 mm max. diameter of tooling. One tool for sure will go for cutting operation (moreover this tool will be much smaller with length compare with bigger machines i.e. – more hits for cutting) so you will have 7 tools so 7 possibilities for different holes for the production part. This article will not about the limitation with speeds and production possibilities so we will ignore some moments. But for Multitool it is important to know that you will do standard parts but not the forming operation like punching of louvers. There are different Multitool heads on the market but there is everywhere the limits for tooling – more max. diameter for the tool – less tools quantity in Multitool head.
Multitool in general is installed in the D-Station head (max. diameter 88,9 mm) so it means the punch machine we spoke about has one D-Station tool possibility. For sure for standard and modern Multitool heads all the tools inside are indexed – it means they could be rotated.
The next generation and more expensive solution is the turret for example with 6 D-station which means, that you can use, let’s say, 3 Multitools inside + 3 tools for D-station. This solution has much more possibilities – you have much more tools in Multitool heads for small diameters, you can do normal cutting with big length tool (for example 80x5) and you can think what to install to other D-Stations.
Today Multitool heads are presented from several manufacturers, but you need to be warned that one Multitool head can cost more than 5-6 thousand of EUR. Anyway Multitool offers great flexibility with indexed tools, there are different solutions on the market and it is very easy to find your Multitool punching tools supplier.
Furniture – global boost for tube bending industry
If you will forget about different tube line applications what could be the big use of tube bending? Sure it is furniture. There is no other massive industry which consumes so much bended tubes for different products. You can just look around and for sure you will find something also near you. Nobody will tell you how many millions of bended tubes are produced every year for example, for iron boards. Moreover we can talk not only about mass market products. It is known that there a lot of design chairs are produced with unique styles and with the use of modern and very expensive tube bending machines.
Yes, in generally bending of tubes for furniture is very simple. In lot of cases it is enough manual or simple semi-automatic machines so the investment for start could be very low. But from other hand furniture is very profitable business for high production and where you mean high production you should consider very high speed production cycle and it is the reason why even for simple applications lot of companies use serious modern machinery. Moreover to save the time and eliminate the human factor loading and unloading operations are performed by robot or other system for automation.
Why we are talking about so serious boost. Just necessary to imagine that in the world there are so many furniture suppliers so if it is very hard to enter the automotive supplier chain it could be much easy to produce parts for furniture. Moreover high production means the development of serious automation for the maximum reduction of fabrication time. And the last thing could be that the start could be done with simple machinery so entry level is not so expensive compare to other markets.
As we said before usually products are simple. But it is very attractive to see the special designs with the bending of full chair body with one tube and full automatic cycle. 3D tube bending solutions in general have no limits so with the powerful machine you can develop a lot of various, stylish and impressive products.
Original and non-original tools
All the producers of machine tools, in particular tube bending machines, punching machines or press brakes offer the possibility to purchase original tooling together with the purchased machine. The advantages are quite simple – under original tooling the manufacturer tries to convince about the high quality of tooling and absence of any faults or problems for the customer. Moreover it is better to get the machine with tooling from one hand, so like the “key turn purchase” where you can start the production immediately after receipt of the machine.
So if everything so good why customer should study the “non-original” tooling not marked with the manufacturer of the machine? The answer is also simple – 90% of manufacturers do not have the real production of the tooling, sometimes they do the project and drawings development but the manufacture takes place outside. Moreover it is the question of the investments – “original tools” are totally more expensive against other competitive offers for these types.
Yes – every manufacturer is not the reseller – finally they are responsible for the machine and tooling is the important part of it. Moreover sometimes, like for tube bending tools it is not just the way for simple installation of tooling on the machine but the question of fine adjustments.
Sure thing if the customer requires from the manufacturer of the machine the guarantee to make his parts with required precision and quality the manufacturer can’t guarantee nothing without supply of tooling from his hands. So it is good for everybody to buy tools and the machine together. But in a lot of cases it is not so important and moreover not so complicated for the customer if he buys his second or third machine. In this case we can also help and offer – high quality press brake tooling, punching tools, tube bending tools from Italy to produce the quality parts.
Special tube bending tools
Besides all different principles of tube bending the execution of special tools is real “state of art”. What is the necessity? Some tubes, in particular in automotive industry require not the standard principle of tube bending performed by tube bending machine as “bend – straight part in min. length as straight part of the clamps – second bend…” Some tubes have no any straight part so the area of this bending is named as “bend in bend”. It is quite impossible to perform this technology with standard tube bending tools and mandrel tube bending machine – there are no possibility of clamping! The solution could be only to manufacture the special tools for the required part where the clamps duplicate the first bend in the groove to make the second one. Tooling to make these parts is really expensive so this is the big question for investments but there is no other way to do the part without the special tools.
Out and back
Social networks and blogs are the huge power and push for today so it is not so good to ignore the good possibilities. And moreover it is not good to stay with the last message that was half or one year ago. So we removed all the old information and welcome you to follow our fresh stuff. We will try to keep active and moreover, publish interesting information that could be useful for industries.
