VOLLMER has entered the worldwide market in the area of tool grinding with the Vgrind 160 grinding machine for solid carbide tools. With the Vgrind 160 grinding machine, five CNC-controlled axes ensure precise machining of workpieces. Using the Vgrind 160, tool manufacturers can produce solid carbide drills and milling cutters with a diameter up to 50 millimetres.
“With the Vgrind 160, we have established ourselves in the international tool grinding market for the first time,” says Dr Stefan Brand, Managing Director of the Vollmer Group. “For us, this is a logical and consistent step in order to develop our core competency in sharpening, and to further strengthen Vollmer’s international position as a comprehensive solutions provider for tool production.”
The core of the Vgrind is the new kinematics system, which is controlled by two vertical spindles. This is because, unlike with a single spindle or horizontal double spindle, multi-level machining can be carried out, thanks to the vertical arrangement. In addition, the spindle arrangement solves the common problems related to fixed and floating bearings, which leads to more precise results when machining workpieces.
Thanks to short linear axis travel distances and swivel ranges, the Vgrind enables the user to reduce machining times for machining workpieces. Nonproductive times are shortened because tool manufacturers can load the two grinding spindles with different tools. An optional tool magazine with eight grinding wheel packages enables tools on the vertical spindles to be changed over automatically. The pallet magazine HP 160 enables up to 272 workpieces to be supplied. The HPR 250 free-arm robot is also a new addition which increases autonomy and efficiency during tool manufacturing – the HPR 250 makes it possible for the previous capacity to be tripled. The automation solutions ensure optimal utilisation of the machine, around the clock.
“We developed the Vgrind as an innovative platform, with which tool manufacturers can produce their products for their market precisely and efficiently,” adds Dr Stefan Brand. “A close dialogue with our customers and the changes in the market motivates us to continuously develop and improve our portfolio,” he added. Vollmer is a technology leader in Tool Grinding machines from Germany, with 14 subsidiaries worldwide.
