AI Description
BetaCapabilities
The Höfler Nova 650 CNC is a precision horizontal gear grinding machine built for high-accuracy tooth finishing on gears up to 650mm in diameter. It handles gear widths up to 530mm and works with modules ranging from 1.5 to 18, making it suitable for both fine and larger industrial gears. The machine includes a Rittal cooling unit and ISI extraction system for optimal precision and shop cleanliness.
Industries & Uses
Gear grinding is essential across automotive, wind energy, aerospace, and heavy machinery manufacturing—anywhere precision gears drive critical systems. Automotive suppliers use machines like this to finish transmission gears and differentials to exact tolerances. Wind turbine manufacturers rely on them for main shaft gears, while construction and mining equipment producers depend on them for reliable power transmission. Smaller job shops also use gear grinders to service existing equipment or produce replacement gears.
What to Check When Buying
Before purchasing, verify the full maintenance history since the machine has been idle since 2010. Request documentation on spindle bearing condition, hydraulic system servicing, and coolant system integrity. Check the CNC control system compatibility with modern programming standards. Inspect the grinding wheel condition and spindle runout carefully. Have a qualified technician inspect the table and workholding mechanisms for any play or wear. Budget for comprehensive recommissioning, including fluid replacement and spindle certification, before returning to production.
