Special purpose lathes
Special-purpose lathes include spherical turning machines for precision ball-surface components and CNC turning-milling centers for automated production of augers, worm shafts, and helical rotors. They are used in valve manufacturing, oil & gas equipment, municipal machinery, and food processing industries.

Spherical lathes are engineered for high-precision machining of spherical parts such as ball valve bodies, butterfly valve discs, and spherical bearings. Their specialized kinematics and tilting worktables ensure perfect sphericity and sealing performance—essential for high-pressure pipeline systems.
CNC turning-milling centers for screw shafts integrate turning, milling, and threading operations in a single setup to produce augers, extruder screws, and worm rotors with complex helical profiles. These machines are widely used in the production of feeders, plastic extruders, drilling tools, and waste-handling equipment.
KNAVI GROUP supplies both machine types from trusted manufacturers in China and Taiwan. All equipment meets international safety standards, includes full English documentation, up to 2 years of warranty, and optional on-site commissioning support.
