Condition: refurbished (used), Year of construction: 1988, functionality: fully functional, Löser centerless tube grinding machine - belt grinding machine - polishing machine - Cylindrical grinding machine Centerless tube grinding / polishing machine for workpieces with a minimum length of 1100mm. The machine was built in 1988 and was completely overhauled in 2012. The machine was converted for polishing and then only polished around 10,000 parts. The machine was no longer used after that. During the general overhaul, the motors, bearings and the entire control cabinet with the frequency converters were completely replaced. The machine can be used for both wet grinding and polishing. Wastewater treatment including pumps is not yet available. We can retrofit these for you free of charge according to customer requirements. The transport systems (roller conveyors) between the grinding stations must also be retrofitted to suit your workpieces. Prjdpfjpugwiox Ag Djd The machine can process pipe diameters from 10mm to 160mm. The grinding motors / polishing motors have an output of 7,5kW per station. The system can be viewed by appointment in our warehouse in D-63128 Dietzenbach.
