milling up to Ø63 mm, end milling up to Ø20 mm.\u003c\/p\u003e\n\u003cp\u003eThe stated capacities refer to standard unhardened steels (e.g., C40, S235). For harder materials or alloy steels, the actual capacity may be lower: in this case, it is advisable to reduce the rotation speed and feed rate to avoid stressing the spindle and tools.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow is the spindle speed adjusted on the BF 28 BDC?\u003c\/summary\u003e\n\u003cp\u003eThe machine features Vario speed, continuously adjustable in the range of 100–1,500 \/ 200–3,000 rpm.\u003c\/p\u003e\n\u003cp\u003eVario adjustment allows fine tuning of the speed to the material and tool diameter without needing to change belts or gears. For face milling of mild steels, the lower range is typically used, while for small diameter holes on aluminum, the higher range is used.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat power supply and motor does the BF 28 BDC have?\u003c\/summary\u003e\n\u003cp\u003e0.75 kW motor (S1 continuous) \/ 1.1 kW (S6 intermittent) with 230 V power supply.\u003c\/p\u003e\n\u003cp\u003eThe motor operates with a standard 230 V single-phase power supply, available in all workshop and laboratory environments. The S6 40% rating indicates that the motor can deliver maximum power for intermittent cycles, while the S1 100% rating indicates the nominal power for continuous use.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat are the table dimensions, travel, and spindle taper of the BF 28 BDC?\u003c\/summary\u003e\n\u003cp\u003eCross table 700 x 180 mm with X\/Y travel of 500 \/ 215 mm, MT 3 spindle taper, 67 mm spindle travel.\u003c\/p\u003e\n\u003cp\u003eThe MT 3 spindle taper is an international standard: accessories (self-tightening chucks, milling arbor holders, reduction arbors) are commonly available.
