ISELI BPN 200 MACHINE FOR AUTOMATIC PROFILE SHARPENING OF BAND SAW BLADES, CONTROLLED WITH 3 CNC AXES IN WET GRINDING EXECUTION HIGHLIGHTS DETAILS TECHNICAL OPTIONS DOWNLOAD VIDEO HIGHLIGHTS BNP 200 • Profile and top/face grinding for standard and stellite- and carbide-tipped band saw blades • Tooth shape grinding via X+Y CNC axis (several circle passes of the band saw blade) • Tooth shape grinding via W+Y CNC axis (finish-grinding of the fix-clamped tooth or top/face grinding) • Operation by colored touch Screen • Tooth shapes retrievable from the control unit (standard memory for 99’999 tooth shapes) • Metric or imperial measurement system selectable (mm or inch) • Powerful water cooling system with fully enclosed protection Hood • Driven by servo motors • Use of linear roller guides for all CNC axes (stiffer engineering and significantly increased lifetime) • Electrically controlled central height adjustment for saw blades • Electrically controlled cutting angle regulation • Pneumatic blade clamping • Grinding-wheel Corundum (Bakelite-bond) Ø 350 / 10 x 32 mm • 1 set of tools / 1 cleaning kit BNP 200 GRINDING PROGRAMS i • Grinding programme for standard toothing • Grinding programme for vario toothing • Grinding programme for winter toothing • Grinding programme for tooth face and tooth back • Grinding programme for several passages • Automatic tracing at the tooth with vibration sensor (impact sound sensor) DETAILS AUTOMATIC INSERTION AND EXTRACTION Automatic insertion of the blade is now possible. The machine inserts the blade until a height preset in the recipe and closes the sheet clamp. The first saw tooth is determined and the tooth pitch is calculated. In the case of variable tooth shapes, the group of teeth is automatically detected. This significantly reduces operating errors and the effort involved in searching for variable divisions. The saw blade can be inserted automatically on-demand in automatic mode. The search for teeth and the determination of the zero point take place automatically and the grinding process is started. In summary, the operator can insert the blade and start the machine by pushing a button. The rest of the work is done by the machine. The option is completed with a revised height adjustment, which works faster and more precisely thanks to a variable-speed drive. ISELI TOOTH TRACING SYSTEM (TSS) Programming tooth shapes is still a major challenge for many customers. The ISELI Tooth Tracing System (TTS) can help! The tooth shape can be probed automatically by an acoustic sensor and saved as a tooth shape. The data obtained are then used for sharpening in the recipe. Parameters such as clearance angle and tooth height are automatically determined and saved by the program. This process enables the exact reproduction of existing tooth shapes directly on the machine without great effort. Inaccuracies are also copied, which means that the removal and thus the costs can be reduced to a minimum, even if the profile is not precisely defined. In addition, inaccuracies on the grinding wheel are compensated for when probing and enable absolutely precise grinding of the profile, even with a worn grinding wheel. Tooth shapes generated on a system using TTS can be read in other ISELI machines of the BNP series. A patent application has been filed for the TTS process and we expect to get the final patent in the coming weeks and months.
