The Bernardo USM 500 is a complete universal grinding machine: it performs external cylindrical grinding (Ø 5–50 mm, up to 400 mm in length), internal cylindrical grinding (Ø 10–50 mm), surface grinding (200 × 50 mm), and tool grinding. The workpiece spindle is inclinable ±90° and the grinding head ±100°, covering practically any geometry in a single 1,300 kg machine.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is included in the standard equipment of the USM 500?\u003c\/summary\u003e\n\u003cp\u003eThe USM 500 includes as standard: cooling device, integrated extractor, dividing head, 4 grinding wheels, 3-jaw self-centering chuck Ø 100 mm, right\/left tailstocks, balancing support, vice for surface grinding, wheel dresser, centralized lubrication, and internal grinding device with 2 grinding wheels.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between the USM 500 and the URS N grinding machines in the Bernardo range?\u003c\/summary\u003e\n\u003cp\u003eThe URS N (800, 1000, 1500, 2000, 3000 N) have hydrodynamic spindles for high cylindrical precision and larger distances between centers — suitable for long workpieces and high-precision production. The USM 500 is more versatile (cylindrical + surface + internal in one machine) but with a 500 mm distance between centers and a standard spindle. The USM 500 is the choice for workshops that need to cover different types of grinding on small to medium-sized workpieces.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the table have hydraulic feed?\u003c\/summary\u003e\n\u003cp\u003eYes. The table of the USM 500 has a hydraulic longitudinal feed adjustable from 0.01 to 6 m\/min with a maximum travel of 480 mm — allowing repeatable automatic cycles without manual intervention for surface and cylindrical grinding in series.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre spare parts and grinding wheels available?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working day shipping.
