CNC machining centres come in all shapes and sizes, so which one do you need? Just consider the difference between a CNC machine with a gantry, a CNC machine with a moveable column, a multitasking CNC machine or one that has been built to your specifications. You want to make a properly thought-out choice, not least because a new CNC machine is a large investment. Based on our many years of experience and our expertise, we will help you make that choice. Check out the most important points to consider when deciding which CNC machine is right for your manufacturing situation:

Through years of experience, UNISIGN has evolved into an international operating company with an impressive installed base. Core to our success has been a clear company philosophy: to design all our standard machines in such a way that they can be tailor-made to create the ideal solution for each individual customer.

Requiring one of the highest chip removal rates in the market, the aerospace industry needs high dynamic machines. The Unipent4000 and Unipro5000 for example are ideal for volume production in this demanding environment and can remove 10 litres per minute of aluminium while maintaining the highest accuracy. For extra large parts or engine components, the Uniport6000-HV, Uniport7000, Unicom6000 and Unicom7000 machines offer the best solutions.

At Unisign we understand that our customers dont just buy a CNC machine, they buy a process. And price per part is key. So for general applications we offer high torque machines with high material removal rates, including 5-axis and 5-sided machining and a choice of moving table or palletized, depending on the footprint available.

Pumps and valves for the oil & gas industry can be highly complex parts to produce with seals, gaskets, flanges and requirements like spiral grooves and elliptical conical eccentric turning. The machining centres from Unisign, with their high degree of automation and specially designed software, are a unique solution capable of milling parts that others cannot.

Heavy duty turning, milling and drilling characterises the production of components for energy-producing equipment like (wind) turbines. So you need a CNC machine that can take the load. A mill-turn machining centre like the Unicom6000, Unicom7000 and the Uniport7000-MTC or a multi-functional Uniport6000 and Uniport7000 are the ideal solution for producing these demanding parts.

With over a million truck front axles being produced every year on Unisign machines its fair to say that we know what we are talking about in applications like these for the truck makers industry. We have established a world leading position by introducing the Unitwin6000, a CNC machine with two very powerful main spindles. The improvement in quality and reduction in cycle time is astonishing!

For everything from bogies to wheels and weld preparation to wheel carrier machining, Unisign has highly versatile machines like the Univers6000, Uniport6000 and Uniport7000. These moving column and gantry style machining centres are part of the machine tool program that have been designed to deliver extremely high capacity, dynamics, rapid acceleration and offer a generous working area.

When considering a new machine for replacement of our aging Unisign CNC machine the basic condition was that all 1000 NC programs of our active parts portfolio can continue to be used on a new machine. Unisign presented an innovative solution based on a Unicom 7000 which meets the challenging project requirement. In combination with a Fastems pallet loading system, our existing portfolio can be managed even more efficient. With the Unisign Unicom 7000, we have an extremely efficient system in connection with the Fastems pallet loading systems, which is tailored to our parts portfolio and is ready to operate without a long ramp up period. A successful project in which we have proven that very complex systems can be replaced smoothly with the right partner.

As a manufacturer of railway bogies in Switzerland, a productivity increase of around 50% was hugely significant for Stadler. And its all down to the UNIPORT7000. Supporting the customers aims of manufacturing flexibility and productivity, this Unisign portal machine halved the usual milling and drilling time. According to Mayer, Its all down to the extremely high dynamics and the very powerful machine capabilities. Reliability was another aspect where the machine excelled said Meyer, another but a crucial differentiator for this particular machine was the simpler and hence much cheaper foundation for the installation.

No-nonsense and a service that continues, also after the purchase. They understand what we do. That is how Mark Das, SafanDarley, describes the relationship with UNISIGN. Furthermore, just like us, it is a Dutch machine tool builder. This meets with our vision. We know what we get. For the production of machine parts, Unisign supplied a new milling machine, also suitable for grinding; the UNIVERS 6000, which replaced two existing machines. The UNIVERS 6000 creates flexibility in the production process, being able to perform multiple tasks, such as milling as well as grinding. It may not be the cheapest machine but UNISIGN offers robust quality and good service, concludes Das. The UNIVERS 6000 is a big hit in our company.

Everything possible in a single setup thats what Voith were looking for so the UNICOM6000 was proposed. The UNISIGN would be our first machine with a HSK1OO interface, said Richard Schmidt, project engineer at Voith. In particular, they were looking for stability and rigidity in the machine concept, since accuracy was important on the heavy parts being produced. In the end though the choice was made not just for the combination of turning and milling; it was also the possibility to do lateral drilling, the availability of good service and particularly UNISIGNs willingness to think with us. And the payback? In practice, Voith found they could shave an entire day off the usual one week production time for some parts!

We are a full service provider in aerospace, machining as well as plant, tool and wind-tunnel model engineering. Whether prototyping or series manufacturing, our machinery and expertise make short processing times possible, even for the most demanding, highest precision machined parts! Unisign Unipro 5000 with a working range of 5.000 x 800 x 500 mm is an important resource to machine also large parts at high accuracy to the satisfaction of our customers.

selecting a valve seat stone | goodson tools & supplies

selecting a valve seat stone | goodson tools & supplies

Valve Seat Grinding Stones have been around for a very long time. Back in the day there were roughing and finishing stones. This was because way back when seats were generally made from common cast iron or hardened steel. Two abrasive specs for the stone was all that was needed to properly grind the valve seat.

Today it is another story altogether as the seat material has become very specific to the applications found on todays engines alloys of multiple metals, powdered metals, super hard materials all designed to prolong the ability of the seat to seal against the valve head.

Stellite is used in many various components and is composed of 75 to 90% Cobalt and 10 to 25% Chromium with or without small amounts of other metals added. It is used especially for cutting tools, hard wear-resistant surfaces, surgical instruments, and cutlery. In our industry, we see it primarily in valves and valve seats. Stellite is a hard material that is very durableand provides extended life to both the valve seat and engine valve. As you know, to grind a hard material you need a softer abrasive that will continually break down and deliver the ability to remove material without immediate load up. The Goodson Stellite abrasive was designed specifically for this material.

So where is Nickel Chrome used? Its used in valve seats where we have a severe duty application such as air compressors, diesel earth movers and even some over the road trucks.Nickel Chrome has a hardness range of 42 to as much as 50 Rockwell so itrequires a softer abrasive combined with a bond to keep the abrasive particles sharp and able to breakdown to grind through this hard material. The Goodson Nickel Chrome seat grinding stone is designed specifically for use on these hard materials.

Beryllium copper(BeCu), also known ascopper beryllium(CuBe),beryllium bronzeandspring copper, is acopper alloywith 0.53%berylliumand sometimes with other alloying elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellentmetalworking, forming and machining qualities. It has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace.Wikipedia

In solid form and as finished parts, beryllium copper presents no known health hazard. However, breathing its dust or vapors, as formed when machining or welding, will eventually cause serious lung damage. Beryllium compounds are known human carcinogens when inhaled. As a result, beryllium copper is sometimes replaced by safer copper alloys such as Cu-Ni-Sn bronze.

Ruby The final abrasive formula were going to talk about is the ruby or red seat wheel abrasive. The Goodson Ruby Stone is our best aftermarket replacement for the original Black and Decker spec. This spec was designed for use as a general purpose wheel to grind most seat alloys from the late 60s to the early 80s.

So, in this article, weve given you a brief overview of the various abrasive formulas Goodson offers in Valve Seat Grinding Stones. Watch for the rest of the story when we talk about seat stone dressing, stone holders and more.
