Equipment Structure:

The machine base is made of cast material and primarily consists of the worktable, movable gantry, movable sliding saddle, drilling and milling power head, automatic lubrication system, protective enclosure, circulating cooling system, digital control unit, electrical system, and other components. It is equipped with rolling hard rail pairs for support and guidance, as well as precision lead screw pairs for driving. The machine tool is characterized by high positioning accuracy and excellent repeatability in positioning.

Product Features

1. Machine Bed and Workbench:

The machine bed is made of cast material and consists of two parts. It undergoes high-temperature annealing prior to machining, followed by a secondary stress-relief annealing process after semi-finishing, and then undergoes final machining. This multi-step process ensures the stability of the machine’s accuracy. The workbench is a single-piece casting made of gray iron (HT250), which is then subjected to secondary annealing and aging treatment. This process provides excellent dynamic and static rigidity, preventing deformation. The work surface features a series of T-slots, arranged in a well-designed layout for secure workpiece clamping.

Two high-precision linear guides are installed on either side of the bed base, ensuring even distribution of load on the guide rails. This significantly enhances the rigidity, as well as the tensile and compressive strength of the machine. The drive system is powered by an AC servo motor coupled with a precision ball screw pair, enabling movement of the gantry in the Y-axis direction. Adjustable bolts are strategically placed on the underside of the bed, facilitating easy adjustment of the workbench's level.

2. Movable Gantry:

The movable gantry is made of gray iron (HT250) and is equipped with two high-capacity linear guide rails on its front side. A precision ball screw pair, driven by a servo motor, facilitates movement of the power head slide plate along the X-axis. The drilling power heads are mounted on this slide plate. The gantry's movement is achieved through the rotation of the ball nut on the ball screw, which is driven by the servo motor via a precision coupling.

3. Moving Saddle:

The movable sliding saddle is a precision cast iron component. It is fitted with two high-capacity CNC linear slide tables, a precision ball screw pair, and a high-precision planetary reducer connected to the servo motor. Additionally, the saddle is equipped with a nitrogen gas balance cylinder, which counteracts the weight of the power head, reducing the load on the screw and extending its service life. This system drives the movement of the drilling power head along the Z-axis, enabling various functions such as fast approach, work feed, rapid retraction, and stop. It also includes automatic chip removal, chip ejection, and pause capabilities for enhanced operational efficiency.
