Product Description

BRIEF INTRODUCTION

LM Double Columns CNC Machining Center

LM series double columns machining center has a compact structure, wide capacity of machining, good rigidity and vibration resistance. It can do milling, boring, drilling, tapping and other machinings. It is mainly suitable for the precision machining of concave and convex molds in the mold industry, complex cavities and surfaces. It is also suitable for precision machining of large and medium-sized parts in industries such as general machinery, automobiles, aerospace, instrumentation, and textile machinery.

Features of Zhongnan's double columns machining center:

1. LM series adopts high-rigidity gantry symmetrical structure, high cutting rigidity and stable running precision.
2. The beam adopts a stepped design structure to control the force and deformation within the effective range.
3. The Z-axis is equipped with a hard rail headstock as standard. The cabinet adopts high damping and high rigidity ductile iron structure, which can effectively suppress cutting vibration.
4. The whole series can be equipped with imported gearboxes, through hydraulic shifting, two-speed transmission, to achieve high torque output.

The whole machine adopts the gantry structure with moving table. The machine bed is fixed, Worktable moves in the X direction on the bed, the ram moves in the Z direction on the slide seat, and the slide seat and the ram move in the Y direction on the gantry beam. The X and Y axes adopt heavy-duty linear guideways, and the Z axis adopts plastic-coated flat guideway. The spindle box is placed at the lower end of the ram. The whole machine has feature of reasonable design, beautiful appearance and convenient operation.

Imported gearbox is optional to improve cutting efficiency.

XY axis with precision linear guideway, and Z axis with high rigidity flat guideway, which is suitable for heavy load and heavy duty cutting.
The Z-axis could be equipped with linear guideway which is suitable for high-precision machining.

Standard with Fanuc 0I MF control system. Mitsubishi, Siemens and other control systems are also available.
