Stanje: skoraj kot novo (rabljeno), Leto izdelave: 2024, as-new polishing machine OPTIMUM OPTIpolish GZ40P with variable-speed retrofit, Siemens inverter, and cyclone extraction system. For polishing wheels with a diameter up to 350 mm, max. wheel width 35 mm, bore 20 mm. Suitable for continuous and intensive industrial use Heavy-duty industrial polishing machine absorbs its already minimal vibrations due to its high own weight Maintenance-free, durable induction motor with smooth operation, housing made of cast iron Blsdjyglkyopfx Acmoh Additionally: Variable-speed drive with Siemens Sinamics V20 inverter Adjustable peripheral speeds from 34 m/s to 6 m/s Robust base with integrated cyclone extraction, resulting in a compact footprint; sound-insulated The base must be filled with concrete by the customer. Automatic start-up feature When switching the external device on or off, the extraction unit automatically starts or stops with a delay of 2–3 seconds. No separate switching on/off of the extraction is required: residual dust is extracted according to hazardous substance regulations after the machine is switched off. The machine is located in 71334 Waiblingen-Beinstein and can, of course, be viewed on site. Please contact us for more information.
