Gantry Type Double Column CNC Milling Machine

Product Description

Product Description
CNC Gantry Milling Machine Features:
1.Extremely rigid and stable structure, the oversized column combined with box type beam construction features additional machine rigidity.
2.The slant beam construction with increased slide way surfaces efficiently upgrades force distribution area this results in greater stability.
3.The spindle head is located at the center of beam, providing high movement accuracy, superior heavy cutting capability and outstanding rigidity. The position is specially designed with symmetrical to center.
4.Equipped with spindle motor ball screw and double counter-balance cylinders are all properly located at the best positions to avoid unequal torque, while assuring the best structural accuracy.
5.The double counter - balancing cylinders on Z-axis are suspension supported, close to the movement gravity center, symmetrical to the spindle drive ball screw and the center of spindle motor. Optional position design not only fully eliminates the possibility of unequal torque, but also provides high feeding accuracy and machining accuracy.
6.Linear ways on X/Y-axis combined with box ways on Z axis. Product Parameters
CNC gantry machining center is a kind of mechanical equipment used in industrial production. It can be automated through computer programs, including parts processing, positioning, testing, etc. CNC gantry machining center has the advantages of high efficiency, high precision and high stability, so it is widely used in machinery manufacturing, automobile, electronics, medical equipment and other fields. 1. Structure CNC gantry machining center is composed of machine tool body, CNC system, machine tool accessories and other parts. The machine tool body includes bases, columns, beams, worktables, spindles and other parts. The CNC system is a key part of maintaining the machine tool. It includes CNC equipment, computers, control software, etc., which can control the operation, processing flow and some additional functions of the machine tool. Machine tool accessories include cutting tools, fixtures, tool magazines, etc., which can cooperate with the machine tool itself for cutting, positioning and other processing processes. 2. Processing principle The CNC gantry machining center can complete a variety of different machining processes, including drilling, milling, boring, tapping, grinding and so on. Its processing principle mainly relies on the cutting tool to remove the material of the workpiece, so as to realize the processing of the geometric shape, contour, size and other precision requirements of the workpiece. There are many kinds of cutting tools, including high-speed steel tools, carbide tools, multi-edge tools, ball-end tools, etc. The choice of cutting tools is mainly determined by the processing material and processing form. During the operation of the machine tool, the CNC system controls the position, direction, speed and other parameters of the tool through the preset program to carry out the machining process. At the same time, many elements such as the positioning, transmission, and control of the machine tool itself need to be considered, so as to ensure the stability, efficiency, and high precision of the machining process.
