Frequently Asked Questions
What materials can the Profi 550 Pro / 400V with 2-axis digital readout work with?
Mild steels, alloy steels, cast iron, brass, and aluminum within the limits indicated in the technical specifications.
For hardened or high-strength alloy steels, it is advisable to reduce cutting speed and depth of cut. The machine is dimensioned for general mechanical production; for special alloys, check the compatibility of the spindle and tailstock Morse taper.
What is included in the standard equipment?
The equipment includes a self-centering chuck, tailstock, steady rest, threading accessories, and a set of wrenches.
For the exact list of accessories and spare parts supplied, consult the manufacturer's technical data sheet. Krollit provides support for original Bernardo spare parts with delivery times of 3-5 working days.
What type of power supply does it require?
See the voltage data in the technical table. Compact benchtop machines are often 230 V single-phase, professional models are 400 V three-phase.
For 400 V three-phase models, an industrial power line is required. Verify the availability of adequate power supply in the workshop before purchasing.
Is the machine suitable for series production?
It depends on the model class: professional Bernardo lathes handle continuous cycles, while benchtop models are suitable for medium use.
Profi and Apollo models are designed for intensive multi-shift use; the Hobby and Goliath series are for occasional use or small workshops.
How much does it weigh and what installation does it require?
Weight varies significantly by model: see "Weight" in the technical table.
Machines over 500 kg require industrial flooring and anchoring with dowels. Benchtop models up to 100 kg are installed on a sturdy workbench with an adequately sized top.
