NEW JAINNHER JHC-12S

Kondisi: diremajakan ulang (bekas), Fungsionalitas: berfungsi sepenuhnya, Löser centreless tube grinding machine – belt grinding machine – centreless tube polishing machine – cylindrical grinding machine Centreless tube grinding / polishing machine for workpieces with a minimum length of 1100 mm. The machine was built in 1988 and completely overhauled in 2012. During the overhaul, the machine was converted for polishing and has since processed approximately 10,000 parts. Afterward, the machine was no longer used. As part of the general overhaul, the motors, bearings, and the entire control cabinet including frequency converters were completely renewed. The machine can be used for both wet grinding and polishing. Wastewater treatment including pumps is not currently included. We can retrofit this to your specifications upon request. The transport systems (roller conveyors) between the grinding stations will also need to be adapted and retrofitted to match your workpieces. The machine can process tube diameters from 10 mm to 160 mm. The grinding/polishing motors have a power rating of 7.5 kW per station. Lrjdpfx Aopugwijlkjk The system can be inspected by appointment at our warehouse in D-63128 Dietzenbach.

Kondisi: diremajakan ulang (bekas), Centerless cylindrical grinding machine Lrjdpfx Asmmqirslkjk MONZESI ROSSI MONZA 1500 currently undergoing refurbishment and complete electrical/electronic retrofit Equipped with Siemens electronics featuring a touchscreen interface, brushless motors on the Z-axis (workpiece diameter adjustment) and regulating wheel (variable speed control), stepper motor for incremental grinding wheel dressing, and automatic size compensation following grinding wheel dressing. Grinding wheel dimensions: 350 mm x 610 mm diameter The machine is available for inspection at our warehouse in Gussago (BS), Italy. Plunge grinding process In the plunge grinding process, workpieces with stepped or contoured outer surfaces, such as injection needles, valves, crossheads, as well as gearbox and electric motor shafts, are machined. Available technologies include straight or angular plunge grinding, single or multi-piece plunge grinding, plunge grinding in multiple operations (simultaneous or sequential), and oscillating plunge grinding. Through-feed grinding is used for the machining of unprofiled workpieces, such as cylindrical and tapered rollers, rings, bars, and hydraulic spools. This grinding method is highly productive and is primarily used for series- and mass-production of precision components.
