DESCRIPTION

High-efficiency CNC vertical lathe, suitable for processing small and medium-sized discs and cover parts High-strength cast iron base and column, with good stability and shock resistance Vertical structure, convenient clamping of workpieces, small footprint and oil-water separation structure The cooling water is clean and environmentally friendly. The separated cooling water tank is easy to clean. The precise, high-rigidity cartridge-type spindle structure is easy to maintain. The spindle sleeve is fully symmetrical and suspended, which can better eliminate the impact of thermal deformation on machining accuracy. High-power AC spindle motor , which enhances the stability of the machine tool operation. The main shaft is lubricated with imported high-grade grease, fully enclosed, maintenance-free. Tool holder, high rigidity, fast tool change, reliable centralized machine tool operation panel, making operation more convenient and fast X/Z axis adopts high-precision ball screw and special bearing for screw, good precision retention Integral fully enclosed protection, environmental protection clean


FEATURE

The unique wall panel + moving column structure, plus the X-direction three-rail design, provides powerful cutting capabilities, exceeding your expectations.

Verified by many customers, it is superior to the traditional fixed column structure in terms of rigidity, precision, speed and stability.

All structural parts are analyzed by finite element to optimize the structure to ensure the stability of the precision of the machine tool in the cutting state, and the mechanical rigidity is increased by 30% compared with the traditional design.

The base adopts box-shaped structure, thick rib wall and multi-layer rib wall design, which can minimize thermal deformation, can withstand static and dynamic distortion and deformation stress, and ensure high rigidity and high stability of the bed.

The integrated overall spindle made in Taiwan meets the requirements of high rigidity, high speed and high precision of the machine tool at the same time. The labyrinth design inside the spindle effectively prevents cutting oil and foreign matter from entering, increases the stability of the spindle, and ensures the service life of the bearing.

The two axes adopt the structural form of Taiwan's heavy-duty roller linear guide + C3 high-speed silent precision ball screw, which has the characteristics of small frictional resistance, strong bearing capacity, and high repeat positioning accuracy.

The two-axis servo transmission system adopts the pre-tensioning structure of the screw, which effectively offsets the thermal expansion caused by the temperature rise of the screw and makes the machine tool have stable precision.

Imported heavy-duty roller linear guides are adopted, with large load capacity and high precision. They have the rigidity of heavy-duty hard rails and fast moving line rails with low wear, suitable for heavy-duty cutting and high-speed cutting.

High rigid structure combined with precision roller guideway can maintain long-term machining accuracy under heavy chips and has a relatively durable tool life.

The X/Z axis adopts high-precision ball screw and special bearing for the screw, which has good precision retention.

Selected Japanese UNITTA 8YU synchronous belt, stable transmission, high efficiency, and small bearing load.

Optional FANUC ai 30 or FANUC ai IP 30 wide-area motor-driven spindle system.

FANUC βi IP 30/8000 wide-area motor is used to drive the spindle system, which provides a high torque value twice that of ordinary motors, and can provide heavy-duty cutting capabilities in the lower-speed operation range.

Low center of gravity structure design and 90°rotatable system control panel provide you with excellent convenience and humanized operation interface for loading and unloading workpieces

Fully protective sheet metal isolates turning chips and coolant in the machine tool, providing you with a safe and clean working environment

Ultra-simplified footprint, combined with rear-exit chip conveyor, not only improves the space utilization rate of your plant, but also facilitates your planning of iron chip conveying system
