introduction

The PM2518 series of high-speed CNC fixed beam drilling and milling machines inherits the advantages of traditional gantry machine tools, such as strong rigidity of the basic frame, symmetrical structure, and strong stability. By optimizing the reinforcement structure and reasonably distributing the mass, the machine has strong rigidity. It has multiple processing functions such as milling, boring, drilling (drilling, expanding, reaming), tapping, countersinking, etc., and is suitable for various mechanical processing fields such as automobiles, molds, aerospace, packaging, hardware, etc.

Ⅱ. Main structure

1. The machine tool has a gantry frame fixed and a movable worktable structure, which is mainly composed of worktable, bed, column, beam, ram, counterweight system, lubrication system, cooling and filtering system, chip removal device, rotary operation panel and electronic control system.

2. Definition of each coordinate axis:

X axis: the worktable moves forward and backward longitudinally on the bed;

Y axis: the ram and saddle parts move left and right along the guide rail on the crossbeam;

Z axis: the ram moves up and down vertically on the saddle along the guide rail;

3. Bed machine (X-axis)

The bed and worktable are made of high-strength high-quality cast iron and resin sand molding. The X-axis guide adopts a heavy-duty guide support structure. The position and number of high-load-bearing slide blocks on each roller linear guide are reasonably arranged according to the mechanical principle, so that the machine tool can obtain high rigidity and long-term stable accuracy.
