μ-ACCURATE MEASUREMENT OF BIG PARTS
What used to be the exception has become increasingly the norm over the last five or six years in the measurement of manufactured parts. The trend is clearly towards 100% control. The company Tool-Tec from Pischelsdorf is well prepared for these“high customer demands”. The company recently invested in another gantry-type coordinate measuring machine. The WENZEL LH 2015 was ordered from GGW Gruber, Tool-Tec’s trusted partner for high-precision,quality-assurance testing.
Tool-Tec was actually founded in 1993 as a toolmaker, but the market gave the Styrians a different direction. Meanwhile the Pischelsdorfer are regarded as the go-to people when large parts have to be turned, milled and/or welded.“We offer our customers tailor-made complete solutions from a single source, whereby a few years ago we specialized in the machining of large parts,” reveals Harald Wolf,founder and managing director of Tool-Tec Werkzeugbau GmbH. Among the Steirer’s regular customers are many well-known mechanical engineers and industrial companies.Typical products ordered from Harald Wolf and his team of 85 employees are, for example, machine base frames including painting. An average annual quantity of 400 means that two such machine components are produced almost daily. 
“We can weld, process and measure parts with a unit weight of up to 15 tons”, emphasizes the Tool-Tec boss. “When welding, we meet the requirements of DIN EN 15085 CL1/CL4-2, DIN EN ISO 3834-2 and EN 1090,”he adds. The approval for the welding of rail vehicles and rail vehicle parts is therefore also given by the Pischelsdorfers.
 
Quality assurance is the trump card
 
The company Tool-Tec’s machinery is impressive. A total of 20 CNC milling machining centers, three lathes, two grinding machines, five welding machines, one painting booth and two measuring machines distributed over two locations are available for mainly series production. Usually the ordered lot sizes range between 5 and 50 pieces. “We strive for lasting customer relationships and impeccable references. To this end, we pursue a zero-defect policy with quality assurance in accordance with ISO 9001 and ISO 14001,” explains Harald Wolf. The demands of our customers are constantly increasing. According to the Tool-Tec managing director, this fact can be seen, among other things, in the fact that just-in-time delivery with test reports is becoming increasingly necessary.“What used to be the exception is now explicitly included in almost every order: most customers want to have their documents documented in black and white and proof that the quality of the manufactured parts fits 100%,”confirms Harald Wolf. That was one of the reasons why he recently invested in another WENZEL LH Gantry. The LH 1210, which has been available for a long time, has already been performing reliable “measuring services” at the Pischelsdorf company for several years. “This coordinate measuring machine has already pointed out errors to us several times. It serves not only as a quality assurance tool but also as a quality-enhancing instrument, because we can now optimize much more specifically,” says one who prefers to act proactively. After all, as a future-oriented company interested in long-term success, it has to stay on the ball permanently in order to succeed in the face of increasingly global competition.

LH 2015 as unique selling point
 
It only moved into Tool-Tec in February 2018, but many potential customers knew about it within a very short time: “Things like this get around quickly,” smiles Harald Wolf. He remembers several phone calls that started in the last months with the words “I heard you have a new measuring machine...”. No wonder, because such a 3D coordinate measuring machine of gantry construction, with which one can measure up to 2 m wide, 4 m long and 1.5m high parts μ-precisely, is already a certain unique selling point. Not everyone has that.
 
The LH Gantry is a CNC coordinate measuring machine with air bearings in all axes. It offers all the advantages and applications of the LH series and has been specially designed for the inspection of large-volume and heavy workpieces. “Thanks to the granite construction the LH Gantry scores with a very high basic accuracy. It is extremely long term and temperature stable. Thermal environmental influences acting on the workpiece and the CMM are corrected by automatic temperature compensation. Another optionally available special feature that has actually been integrated into the Tool-Tec solution is the active pneumatic vibration damping, which provides optimum protection against vibration,” describes Roland Widrich, Sales Manager Austria at GGW Gruber.
 
Scanning rotary/tilt switch
 
For Harald Wolf, it was actually clear from the very beginning that the new measuring machine would again be“a WENZEL”: “On the one hand, the LH 1210, which has been available for a long time, has been working perfectly for years, and on the other hand, we received consistently positive feedback when we asked other users about their experiences with this CMM. Last but not least, the support provided by GGW Gruber is also excellent: “Whenever there is a measuring problem, it is solved professionally within the shortest possible time,” he praises.“I often turn to Mr. Widrich and his colleagues for detailed programming questions,” says Walter Artinger, workshop manager at Tool-Tec. The Styrian is extremely pleased that quality assurance and thus the LH 2015, among other things, are now also part of his area of responsibility: “I actually come from milling and working with this CNC coordinate measuring machine represents a new challenge for me. It’s like a little Mercedes,” he compares. “I haven’t found any weaknesses with this machine yet and the service from GGW Gruber is also perfect,” he adds.

Fun to learn how to place the workpieces to be measured in the LH Gantry to get the scanning probe to the desired location. Because one thing is “law” at Tool-Tec: no product leaves the company without having been carefully examined in an LH gantry. During this quality check, not only the most varied dimensions, distances and tolerances are checked, but also fits, position positions and much more. An average measurement log shows between 50 and 100 positions, the complete geometry of each individual component is precisely measured at 2 μ. A scanning rotary/tilt switch that can be tilted from 0 to 360 ° and from 0 to 105° in 720 positions makes this possible. “One button for all positions - that means flexibility. Throughout the scanning,this not only works very accurately, but also very quickly. Within the shortest time, dozens of measuring points are recorded and captured”, Roland Widrich finally
emphasizes the efficiency of the WENZEL 3D gantry measuring device solution used at Tool-Tec.
