Qg1, the CAD CAM tool grinding software!

The new grinding software from Schneeberger proved to be exceptional. In the development phase, entirely new approaches were applied to tool grinding. Fundamentally unlike other programs, Qg1 is based on a 3D model that is generated with the integrated geoMod module. The grinding path is calculated using 64-bit technology. This off course with unprecedented speed and precision: Accurate to 13 digits back. Any form and shape deviations of the grinding wheel are also taken into consideration. The perfect geometry in accordance with the geometric requirements are calculated into the finish ground tool. With just a few clicks the software produces the complete tool. Using the NTTE function (New Tool Toogle Extractor), after selecting the desired tool type in the extensive database, the operator generates the complete grinding program with just 3 more clicks. Number of teeth, number of centre cutting wings and tool diameter – no further inputs are required. The grinding process and paths, as well as the required wheel shape, are automatically generated. Using the clearance Qreator function it is possible to define individual clearance angles and land width for different sections of the tool. Individual grinding paths can be generated with ease, using the path Qreator. And the internal search engine Toogle Search simplifies the process of searching for existing tools or existing wheel packages in the database. The new CAD CAM software has been designed as an open programming system, to facilitate the data exchange with external programs. It now becomes possible to exchange conventional data formats, such as GDX, STEP, DXF, as well as the user‘s own ISO programs with Qg1.

NGC: A COMPLETE SUCCESS IN ITALY TOO, FROM NORTH TO SOUTH

Schneeberger is celebrating major sales success in Italy with the new ngc grinding machine. The new compact machine from Switzerland has a lot going for it. Huge flexibility in applications, a high removal rate when grinding from solid, as well as a broad tool spectrum from small to large diameters and lengths all is impressing our Italian customers. Sufficient space is available to grind tools with a length of up to 400 mm. Spiral and brazed profile tools are a speciality of the ngc machine. It is possible to grind carbide taps, hobs and shaper type cutters. Naturally, all standard shaft tools are covered as well. Both carbide and HSS are produced efficiently.

 

Here are a few testimonials and comments from our Italian customers: Mr Renato Bernardi of ABS Utensili (www.absutensili.com), located in the province of Treviso, stated: “Numerous different grinding machines from many different manufacturers are in our company. Our range covers the entire tool spectrum for the machining of metal parts. In addition to the production of tools, we also offer tool sharpening services. The volume of business generated here makes us one of the most important suppliers in north east Italy. We are expanding our service spectrum with the purchase of the new ngc from Schneeberger. In particular, key for the decision is the flexibility of the applications and the flexibility of the machine using the integrated wheel changer. The simple and functional operation of the machine makes it possible to attain high levels of productivity.“

 

Further on in the heart of Tuscany, Mr Gianluca Fantacci from G3 Utensili (www.g3fantacci.com) in Siena had the following to say about the latest acquisition from Switzerland: “As a traditional and leading company in producing woodworking tools, our product ranges from planer heads right through to thread taps and multi fluted milling cutters. The short set-up times on the ngc have convinced us that this machine is tailored to our needs. This enables us to switch from the production carbide planing knives to grinding of end mills within a matter of minutes. Impressive here is the simplicity of the equipment set-up, as well as the high precision of the final results. In addition, the integrated tool loader and the wheel changer increase the flexibility of the machine. With the new machine from Schneeberger we have substantially increased our capacity and we are now able to offer our customers significantly faster delivery times. The high quality of the grinding results produced here is equally impressive.

 

And what does Mr Lapi from CUP (www.centroutensilipontassieve.it) think about the latest machine in his production department? “We are a specialized company supplying the fashion and gold jewellery industry, which is typical of our region. During the production of usually extremely delicate tools, we require particularly precise machinery with a high degree of repeatability accuracy. We have found these characteristics in the ngc from Schneeberger. Furthermore, it was very easy to integrate the machine into our production and full productivity was achieved after a very short start up time.“

 

To conclude our brief excursion through Italy we arrive on the slopes of Vesuvius, where we are welcomed by Mr Peppe Battella, proprietor of Utensili Service, Mariglianella, Naples, (www.untensiliservices.com). “I particularly like the machine because it is possible to grind long tools of up to 400 mm in length. This has allowed us to expand our service spectrum for our customers. Furthermore, the machine exhibits a high degree of thermal stability and is extremely reliable.“

Burrs – the latest status, with Schneeberger

Today, carbide and HSS burrs are used in numerous applications and are suitable for both, manual and machine use. Depending on their form and design, the little helpers are designed for deburring, edge breaking, weld seam and surface processing of various materials, and are used for example in a production environment, prototype design, specifically in the jewellery industry and dental technology.

 

The developers at Schneeberger have reworked the software for grinding burrs from ground up to bring meet today’s standards. Starting with version 5.4.6, all forms according to DIN 8032 or ISO 7755 are available for grinding. From a cylinder (form ZYA) and round cone (KEL) right through to a tear drop shape (TRE), sample tools can be called up from the available default database, or independently designed. If necessary, the cross-teeth can be programmed with positive or negative helical angle and the wheel selectively follows a constant lead or constant angle. The face geometry can also be variably configured. Be it grouped together, positive or negative tapered, various types are possible as shown in the figure below. The generation of the geometry and the calculation of the grinding path offer another unique advantage, an un­equalled capability in the world of tool grinding software. Once the user has entered all of the data, a 2D DXF as well as a 3D model, referred to in short as a GeoMod, are generated during the file safe process.

 

In simple terms, this represents a wire model with shell. The grinding wheel moves along a displayed grinding path, so that any wrong program entries are instantly visible by displaying the actual grinding path on the simulated model. In contrast to the simulated approach, where the grinding wheel is programmed in a certain way according to a preset formula, all in the hope that a good tool is produced, the actual grinding point is constantly monitored by software and rigidly follows the geometries contact point. At the same time, the grinding wheel is automatically positioned in a way that the tooth geometry can be reproduced in a precise as possible manner. This way it is now possible to evaluate whether the grinding wheel geometry used is suitable for the production of the tool, or if the wheel is unsuitable before grinding starts.

Construction project in China

For over one decade now, Nanjing – with its 7.5 million inhabitants – has been home to the head office of our subsidiary in China. Established in 2005 our branch in the district of Jiangning, which today has almost 800,000 inhabitants, at that time we relocated the service centre from Wuhan farther south along the Jangtze. The Jiangning Economic & Technological Development Zone was established in 1992 and has been developing at a very rapid pace since then. Where farmers once planted their vegetables, countless factories are standing there today. Office buildings, hotels, shopping centres, residential areas, schools and universities. Over the past 10 years we have been able to witness the rapid development of this urban area. We have observed how the city‘s metro started to reach out into the suburbs, how the new highway leads right into the centre of town, how a second terminal was added to the international airport and the high-speed trains from across the country arrive in the newly constructed Nan Zhan (South Railway Station). Incidentally, the railway station with the second largest total square footage in the world! And it goes on. The area around Zhuangpai Lu, home to our Chinese company, was once primarily an industrial area, although it has since developed into more of a centre of the new Jiang­ning, with large shopping malls, hotels and residential apartments. Industry is moving to the outskirts of the city. And Schneeberger Nanjing will soon be moving into new premises too. However, there is still much to do. A suitable building will be available shortly. The building is situated approx. 10 km south of the current site on the Shui Ge Road No. 8; it does not harm that 8 is considered a lucky number in China. It is also necessary to tackle the interior fittings of the (doubly lucky) Unit No 8. For our construction project, which is somewhat modest by Chinese standards, we will be working with a small construction company and the work will be accomplished with the help the standard day labour. We are obtaining a number of quotes on the interior design to assure best synergies. Although it is not local custom, we are soliciting proposals from various companies and engineers for the project. However, contrary to one bidders suggestion, we did involve a Feng Shui expert simply because we are not permitted to make any changes to the building code or structure. During the actual construction, the greatest importance is being placed on the quality of the construction materials and equipment used. The type of concrete and brand of paint are being specified in the construction contract as well as the stone slab and the make of the wood boards. However, brand name products are sometimes compromised. This can equally happen with stone slabs from Marco Polo, hardwood flooring from Naturo and toilet bowls from Geberit. It is therefore necessary supervise the purchase of the construction materials in person. After all, it is not our intent to encourage anyone to use counterfeit products in order to improve profit margins. In fact if the intention is – like us – to move ton’s of machinery on the planned demo room ground floor, then the load-bearing capacity of the floor foundation must be tested. It is an un­usual practice to use reinforced concrete, unfortunately the more commonly used practice is to fill the ground with rubble and covered it with a thin layer of concrete. In other words: Everything comes out, pour new concrete and reinforce it right from scratch. The premises will be ready for occupation 1st July 2015. Given the speed demonstrated by China in its development, we have no doubt that the interior build-out will be completed on time.
