In order to make the processing more economical, many companies will use dedicated carbide cutting tools. These tools have tolerances up to the micron level. In order to manufacture these tools, Wolf uses the measuring equipment of Werth company, which gives them strong support to focus on precision measuring tools. The die and tools division GmbH of Wolf group was established in 2000, it is a subsidiary of Wolf Group. It started out making cutting tools and bending systems. Based on the principle of synergy, they incorporated the experience gained in the coating field of their sister company (WolfBeschichtungsGmbH) into the field of forming, bending and stamping tools. Today the company has a wide range of business, including: three-position grinding, contact corrosion, stamping tools, plastic injection molding and even circular parts for the automotive industry. In order to further expand its business scope, a new building was built in 2002 and a huge investment was made in upgrading its manufacturing equipment. This includes the WerthVideoCheckIP type coordinate measuring instrument, which is equipped with multi-sensor technology, enabling it to quickly measure 2d and 3D geometry. With the help of image processing sensors, 2d profile features of cylindrical and undercutting can be accurately acquired and evaluated. VideoCheckIP coordinate measuring instrument is also equipped with motor driven, throwing mechanical probe. Multi-sensor measurement equipment can integrate multiple measurement methods, using top or bottom light source, contact or laser technology. The 2DBestFIt package is able to take tolerances into account. In addition, the measuring instrument is a modern contour projector. HorstWolf, general manager of focus tool precision measurement Wolf group, said: 'this measurement system is very important to us. The automotive industry, in particular, needs data that reflects the geometry of its components, whether they are plastic, sheet metal, or whole cemented carbide. ToleranceFit is also often used for stamping die. If the tolerance grade is not correct, the stamping part will be severely damaged. That would add significantly to the running costs.' The Tool technology division of the Wolf Group accounts for 50 percent of total sales. Its specialty is the manufacture of special carbide tools such as stepping drill bits and production multipurpose tools. To manufacture these precision tools with tolerance grades of ±3μm, appropriate measuring equipment must be available. Based on the valuable experience of the Tooling department, Wolf Tools decided to adopt the 'VideoCheckVHA', a multi-sensor coordinate measuring instrument from Werth Measurement Technologies. Precision air bearings and carbide bases allow measurement accuracy of several microns. The 10nm resolution and 3d error compensation make the measurement error level 0.25μm (according to German standard). Every micron-scale data is recorded by the contact sensor, measurement probe system, laser probe and Werth fiber optic probe (probe ball diameter as small as 20μm) fused with the image processing sensor. This allows flexibility for measuring tasks with a variety of tools, such as hobs, molds, reamers, stepping bits, twist bits, grinding rollers, and roller dressers. Werth Measurement Technology emphasizes the excellence of its equipment: 'Our measuring equipment is designed specifically for ISO10360 and VDI/VDE2617 standards, that is, our measuring system is combined with the Length standards of the German Metrology Institute. For us and our customers, this means reliable and complete measurement results.' Werth's coordinate measuring apparatus can be used as a reference for measuring equipment, providing customized contact tolerances for customers. 'In the future, tool manufacturing accuracy is not only on the micron scale, but on the 0.1 micron scale,' HorstWolf said. 'When I look back at the progress made over the last three or four years, I think of Werth's high precision tool measuring instrument. It's clear that this company is taking advantage of technology and innovation at the forefront of the industry.' Wolf Group Founded in 1985, the Wolf Group is headquartered in Brumichelba Misau, Germany, and employs 450 people. IT has 4 subsidiaries including tool technology, coating technology, profiled and mold manufacturing and IT consulting company. The main business includes the manufacturing, coating and post-maintenance of tools and molds for automotive, aerospace, energy and other industrial sectors.
