China Horizontal CNC Lathe Machine

NL251H CNC Lathe is designed as a double-coordinate lath with two axes moving simultaneously and semi-closed control. with mechatronics design, it adopts all closed protective enclosures with sliding door open to left and the operation panel is on the right fixed covers. This design goes with ergonomics and provides a easier operation. High speed silent ball screw connects motors through couplings directly and features with its high speed, low noise, high positioning accuracy and high repeatability. Built-in absolute coder has no add-up error, no need to memory and no need to find a reference point and the position information won't lose when power off. The machine is characterized with its powerful function, high accuracy, reasonable design, pleasant outlook, easy operation and convenient repair.
Body: Mechanical, electrical and hydraulic integrated layout and 45° Horizontal bed provide compact structure, high rigidity, smooth chip removal and pleasant outlook. The adopted rolling guideway and high silent ball screw provide high speed, less heat and high positioning accuracy. The machine also adopts enclosed protection, automatic-chip-removal, automatic lubrication and automatic cooling.
Bed: Horizontal bed and 45° Inclined guideway provide compact structure, high rigidity, smooth chip removal and pleasant outlook.
Spindle: The main transmission system is driven by high-quality servo-motor through a pair of belt. The spindle ranges 20-5000r/min. The front support adopts tri-high-precision angular contact ball bearings and the back support adopts double-high-precision angular contact ball bearings to meet the axis and radial force demand.
Tailstock: Programmable servo tailstock can be controlled by program, operation panel and foot board and automatic tightens workpiece through moving back and forth, shortens the processing time by avoiding manual operation.
Tool rest: High quality hydraulic tool rest from Taiwan is characterized with its short ATC time and high reliability.
Drive: FANUC high-quality servo motors are used to ensure the high positioning accuracy, repeatability and flexible movement.
System: FANUC 0I-TD CNC system and α I series AC spindle and servo motors with high performance and reliability are adopted.
