Turning center LT-400

LT-400 CNC Turning Center

A high-performance CNC turning center with a 30° slant bed, designed for precise and efficient machining of medium-complexity parts. The model combines precision mechanics, high structural rigidity, and a modern control system, ensuring stability, reliability, and productivity in batch production.

Key Advantages:

• High Rigidity and Precision Construction — the main bed is a one-piece casting from high-quality Meehanite cast iron (FC30) with reinforced ribs, providing excellent rigidity for heavy-duty and high-speed cutting. The 30° slant bed creates an ideal support base for the spindle, turret, and tailstock with a low center of gravity.

• Precision High-Speed Axes — the X and Z axes are equipped with absolute AC servo motors, ensuring rapid acceleration/deceleration and high thrust force. The use of pre-tensioned, backlash-free C3 class precision ball screws with direct motor coupling guarantees high positioning accuracy and minimal thermal deformation.

• High-Precision Linear Guides — heavy-duty zero-clearance linear rolling guides on the X and Z axes provide high traverse speeds (X: 20 m/min, Z: 24 m/min), excellent contour cutting accuracy, low friction, and long service life.

• Powerful and Precise Spindle — the spindle features P4 class precision bearings (front support: 1 double-row roller + 2 angular contact ball bearings; rear: 1 double-row roller bearing), ensuring high machining accuracy and long-term stability. It is driven by a high-efficiency V-belt, providing high torque and easy maintenance. Spindle speed is adjustable in the range of 30–4000 rpm.

• Reinforced Tailstock — a programmable hydraulic tailstock with an MT5 taper and 100 mm quill travel provides reliable support for long workpieces.

• Advanced FANUC CNC System — the FANUC 0i-TF controller with an 8.4" color LCD display offers easy programming, extensive functionality, and support for Manual Guide 0i interactive programming.

• Collision Protection — an axis collision protection device absorbs and reduces impact force, maintaining machine accuracy in case of unexpected events.

• Strict Quality Control — each machine undergoes a 100-hour run-in test, geometry inspection with a laser interferometer, and a test workpiece machining to guarantee accuracy.

Application Area:

Designed for high-precision turning of parts in various industries: general mechanical engineering, automotive industry, component manufacturing, medical equipment. Particularly effective for machining shafts, bushings, flanges, rings, and other parts requiring high accuracy, surface quality, and productivity. The possibility of integration with a bar feeder and a robot makes it an ideal solution for automated production.
