A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The rated power typically ranges from 5.5 to 22 kW, but the exact value depends on the machining application and must be confirmed with the manufacturer.
Select the rated speed and maximum speed based on the cutting tool material and workpiece. Higher speeds require precision bearings and balancing. Always verify the motor's speed range with the supplier.
For heavy-duty operations, liquid cooling (IC416) is often preferred over forced ventilation (IC411) to maintain stable temperatures. The choice depends on the duty cycle and ambient conditions.
Regular checks include monitoring vibration, noise, and temperature. Bearing lubrication and cooling system maintenance are essential. Any abnormal signs should be addressed promptly to prevent failure.
