Another factor is the user-friendliness of the system, plus the service offered by Open Mind.” The technical performance of the individual machining cycles with options for multi-axis and five-axis machining, deep-hole drilling, automation and measurement technology, is and remains a decisive factor. Head of department Marco Mergner highlights the importance of HyperMill to the business: “HyperMill not only meets our requirements but plays a decisive role in ensuring that we keep pace and continue to develop. The 190-employee Knarr Group, located in Helmbrechts, Germany, is a tool and mould maker that manufactures standard parts through to complete mould bases using the HyperMill CAM system from Open Mind Technologies. The operators are particularly keen on the availability of numerous canned cycles, such as those for drilling, which are simply and quickly parameterised.įor further information Author MTI Magazine Posted on JanuCategories FEATURE ON CNC & CAM, INTERNATIONAL NEWS Leave a comment on High-accuracy mill-turning of forging dies CAM system saves time and money at Knarr Krenhof’s young team found no difficulty programming on the shop floor in Heidenhain’s Klartext conversational language.
The TNC 640 simplifies the structuring of sub-routines, allowing complex programs to be assembled and run. Downloading the NC program from the CAM system, for example, is quick and easy via Heidenhain’s TNCremo Windows-based communication software.” “Dynamic, precise motion control provided by the TNC 640 CNC exploits the potential of the machine to the full,” he continues. The universality of the Heidenhain TNC 640 CNC system is also important in achieving top quality standards, as it controls both milling and turning operations on the machining centres. One factor helping us to maintain high standards is our use of modular carriers with replaceable die inserts, enabling optimum tools to be used in our forging process to guarantee precision. They are the first first-axis machining centres in the Köflach factory and were purchased along with a new CAM system.įranz Krammer, toolmaking manager at Krenhof, says: “Customers in the automotive industry want the 10,000th forging to look exactly like the first, so quality as well as price is increasingly important. The need for Krenhof AG, an Austrian forgings manufacturer, to produce an increasing number of modular dies for the automotive industry has led to the purchase of two Alzmetall mill-turn centres equipped with Heidenhain TNC 640 controls.
