This flat bed CNC lathe is equipped with high-accuracy bearings and ball-screws, 3-jaw manual chuck, vertical 4-way tool turret, automatic lubrication system, and manual tailstock. Very rigid single-spindle headstock, combined with variable-frequency spindle motor, can stand up to the most demanding cutting requirements.
Available CNC systems include FANUC, SIEMENS, GANZHOU CNC, HUA ZHONG, and OMORI, customers can choose according to their specific requirements.
Waterproof Design
In the design of protective guarding, labyrinth-style joints are created in such places as where the doors meet, where the ball-screw cover and the guard of the headstock meet, for example. Splash guards are also located on the pedestals of the CNC lathe, all of which improves the water resistant character of the entire machine.
The design of the overall guarding structure also maximizes the inner work-area of the CNC lathe, so there is more space for special accessories and tooling, also making the machining of special or odd-shaped parts easier.
Safe and Reliable Electrical Design
The electrical cabinet of our CNC lathe is well-designed and is simple in structure, with good closure and sealing characteristics.
The door incorporates a two-point lock for operator safety.
The internal design of the cabinet is clean and elegant, and its DC unit incorporates an integrated circuit board, with neat wiring and great reliability.
Design Features of the Spindle
The spindle realizes step-less speed change via frequency modulation, and can therefore accomplish constant surface speed machining. The front support for the spindle has triple angular contact bearing, and can withstand considerable radial and axial forces. The spindle power train includes a heavy, narrow V-belt, smooth drive system, little thermal distortion, and stable accuracy.
Lubricating Mode
This series of flat bed CNC lathe incorporates an automatic lubrication system whose output varies according to actual travel of the axes, thus ensuring sufficient lubrication for each way while saving much lubrication oil over time.
X-axis, Z-axis
X-axis and Z-axis are equipped with high-quality ball screws on both axes, with gibs and low-friction plastic material, and 45 degree locking nuts. The rapid speeds are much quicker (6m/min. for X, 10m/min. for Z), and double waterproof structure prolongs the life of bearings and ball-screws, and improves the overall performance of the flat bed CNC lathe.
