  Plateforms for Binder jetting
Posted by: PiëR - 04-23-2021, 01:22 PM - Forum: Metal - No Replies

Hello,

I have some questions regarding the moving plateforms :
- Is using regular seal for piston (O-ring type or others) enough to prevent powder falling into the gap with the walls ? I found no info about that.
- Is there any advantage to use rectangular plateforms, instead of circular ones ? I noticed many machines use these.

I thank you for you attention.

  Lantek and Trumpf join forces
Posted by: admin - 03-30-2021, 07:30 AM - Forum: Laser cutting - No Replies

This is an exciting development where Trumpf has acquired Lantek, but Lantek will still operate independently. and in partnership with Trumpf.

The objective of both companies is to have open systems for CNC programming of almost any make, model and type of cutting machine combined with the complete management of a sheet metal manufacturing facility.

Machine tool manufacturers now understand that the market is demanding open systems so that they can have connectivity and which can move towards a smart factory. Previously, there were many stand alone CAM systems that could not share data and were machine specific. Now companies want to choose which machine and technology is best for their application (laser, punching, oxy-cut waterjet etc). In addition, they want to use the information about the machine and factory floor performance to help them manage their whole factory better. The areas included are sales, service, quality, manufacturing execution, etc. and also links to their customers and suppliers.

By involving customers and suppliers as part of the structure of their own business, the benefits are potentially huge as it helps to increase quality and reliability of supply, reduces costs of materials and secures orders for the future through a loyal customer base.

The industry has moved on a long way from simply reacting to orders and trying to get them out as quickly as possible. Systems like the one Lantek offers have the potential of completely transforming a manufacturers business and with an open system, any manufacturer can begin the process of transforming its business irrespective of the setup and the machinery it has.

For Trumpf, they will be able to have this technology to offer with their machines, integrate it with whatever other machinery or processes the customer may have and accelerate the development of a smart factory which in turn will benefit the industry as a whole.

Posted by: admin - 03-11-2021, 10:18 AM - Forum: What's new in advanced manufacturing - No Replies

With a solution to the Covid crisis on the horizon, hopefully we can get past the terrible events of 2020.
The fallout in economic terms has yet to be fully quantified but the crisis has highlighted how companies need to be more resilient and flexible.

There has been a move for reshoring in many countries and supply chain resilience is a big driver for this. The potential of something like the pandemic happening again has made a lot of companies think hard about how they can have more security in their supply chains, so will probably want to think about multiple sourcing locally, in house manufacture and reducing the shipping of vital parts from the other side of the world.

Other factors will be flexibility for workers. Many companies have made a permenant shift to homeworking. Where this is not possible, automation is being considered. With record low interest rates and machinery suppliers wishing to make up for a bad year now is the time to take the plunge.

It makes much more sense to automate expensive equipment to maximise production and up time in any case.
Even for companies that make short runs of parts it can be effective. I have seen some really successful installations at companies like Martin Baker where Horizontal machining centres are fed from a pallet handling system giving them about 90%+ up time. Other systems from companies like 3R are within the reach of most manufacturers.

Industry 4.0 is coming into its own now to meet the demands of flexibility. Not only does this improve maintenance and repair of equipment with in depth machine health monitoring, but it also gives much more reliable and fast feedback on the state and costs of production. 

In addition, it gives companies the opportunity to integrate with both customers and suppliers. Not only will this increase efficiency but it will also greatly increase customer loyalty. 

Companies that don't have this will find that it is very difficult to break into key accounts. This model has been used in automotive for many years with old technology. Now with Industry 4.0 it can spread to a much wider range of applications.

Here is a link to a Mckinsey report from 2020 on the subject.

  Binder jetting
Posted by: admin - 03-11-2021, 09:41 AM - Forum: Metal - Replies (1)

This is a technique where the poeder is added layer by layer and each layer is fused together with a binding agent (glue) to form the part. As with other AM systems, the part gets built up inside a cube of powder so that it is supported by the surrounding powder as it is buit.

Once finished, the powder is removed and the part is a finished shape.

This can be used with both metal and other materials. Depending on the application, such as sand casting moulds and cores the part is ready for use.

For metal applications the part needs to be sintered to make it structurally sound. Other heat treatments include infusing the binding agent with a metal binder such as bronze.

Esprit CAM has been working with CETIM in Fance to develop CAM applications for the technology. You can read about it here.

For a more general overview of the technology there is a nice piece you can read here.

  MSS and Bystronic working together
Posted by: admin - 02-05-2021, 10:28 AM - Forum: Nitrogen generation - No Replies

I have known MSS in Rugby UK for years  and have always been impressed with the Nitrogen generation cubes they have developed over the years.

In the early days they just sat on a pallet, but since then they have become much more sophisticated and the plug and play generators they make now are really impressive.

The economics and convenience of nitrogen generation as opposed to bulk delivery seems to me to be a no brainer especially if you can lease the kit and spresd the cost while using it.

Now they have agreed a tie up with Bystronic in the USA.

  Automated cleaning of wing surfaces
Posted by: admin - 01-27-2021, 11:12 AM - Forum: Automation - No Replies

Laser cleaning robots are being used in the assembly line for the F35 Lightning.
This process replaces hand cleaning of paint to allow bonding of nutplates. Previously with the hand process the results were not consistent so the bonding sometimes failed. The laser cleaning gives a much better result so that bonding is now reliable.

We all know that Covid-19 has decimated the exhibitions calendar, with the cancellations of MACH, IMTS and many others. This has resulted in many companies and organisations producing webinars, and online press conferences.

After a great deal of work in the back office, we will shortly be able to publish webinars, and even offer reminders to interested participants. Look our for the announcement coming in the next couple of weeks!

  Purchasing first Vise : any recommendations?
Posted by: BrentButterworth - 09-29-2020, 09:40 AM - Forum: Machine techniques - Replies (1)

Hey GJ!

Need some help/advise on a bench-table vise for my home garage. Majority of work is automotive. Specifically need a table vise to use when working on suspension bits like shocks, struts, and dampers.

Won’t be the only use, am learning how valuable a vise is in general. Am a big supporter of USA quality tools quality where they exist, but often not readily available to purchase IE; Wilton, Columbia, etc. Also, have NO idea even browsing retail selections what size would be appropriate.

Photo Can this machine produce useful work?
Posted by: rebertjboyce - 07-17-2020, 01:24 AM - Forum: Machine techniques - No Replies

Principles to run the machine

These are a few basic principles

[1] an enclosed container (X) of air submerged in water has a lifting force (Y) equal to the volume of the water displaced minus the weight of the container;

[2] connecting multiple containers one on top of the other creates a combined lifting force of (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)+ (Y)
Which is a greater lifting force than (Y);


[3] the energy needed to fill one container is equal to the energy needed to sustain the combined lifting force of the 10 (ten) containers referenced above;
Formula used (ATM/V1) X V1 = bubble size
Output of this machine is 118,428 pounds of lifting force moving at 33 feet per second at any one moment in time
