Several structures of five axis turntable

The first structure is the turbine vortex rod structure. This is the most common structure, and most turntables use this structure. This turntable is also a traditional structure, driven by a motor to drive gears, which in turn drive the turntable to rotate. This structure has good rigidity. Most machine tools that add a fourth axis function use this type of turntable. The second structure is the DD motor structure. This type is directly driven by a motor, which has high speed and positioning accuracy, but its disadvantage is poor rigidity, making it suitable for light cutting machining. At present, the domestic 3C industry adopts DD motor structure. The third structure adopts a roller cam structure. The most typical one among them is Japan's Sanko turntable. Its characteristics are excellent accuracy and efficiency. The weight occupied by the same volume performance is lighter than traditional ones. The fourth structure is the harmonic reducer structure. It is a turntable used for the processing and production of 3C mobile phone casings in recent years. This turntable is almost used in this industry. The fifth structure adopts a PRG gearbox structure. The most typical example is Lehman Brothers in Switzerland. The turntable adopts solid gear teeth, steel gears, and worm gears. The edge coating is hardened and polished. Running in the oil tank+four head worm gear without clearance storage+long-term gapless pre clamping+long-term high precision, almost no wear. Make the turntable widely used in the host factory.
