※ 機(jī)床采用龍門(mén)定梁框結(jié)構(gòu)，長(zhǎng)久保持良好的剛性和精度，扭矩大，動(dòng)態(tài)特性佳，根據(jù)加工需求充分吸收了國(guó)際先進(jìn)機(jī)床設(shè)計(jì)理念。
※ 關(guān)鍵件包括床身、立柱、橫梁、滑鞍、滑枕、工作臺(tái)等均選用高強(qiáng)度樹(shù)脂砂造型，高強(qiáng)度優(yōu)質(zhì)鑄鐵，可耐重切削并長(zhǎng)期保持精度，穩(wěn)定性高。
※ 熱對(duì)稱主軸箱，高精度角接觸軸承安裝于主軸頭部和尾部，有效確保剛性和精度。采用加大直徑和厚度的主軸，進(jìn)一步增強(qiáng)剛性。主軸選用大功率電機(jī)驅(qū)動(dòng)，大馬力，高扭矩，即使在低轉(zhuǎn)速狀態(tài)下也可以實(shí)現(xiàn)高精度的重切削。
※ 進(jìn)給系統(tǒng)采用加大直徑、預(yù)拉伸的滾珠絲桿，增加絲桿剛性并能有效防止絲桿熱變形。
※ 螺旋式與鏈?zhǔn)阶詣?dòng)排屑結(jié)構(gòu)相結(jié)合，確保排屑的順暢。
※ X/Y軸采用進(jìn)口超重負(fù)荷線性導(dǎo)軌，Z軸采用矩形淬 硬貼塑導(dǎo)軌，低磨損，高負(fù)載，確保機(jī)床的長(zhǎng)期使用精度，可大幅提高切削時(shí)的精度與剛性。
※ 主軸中心距Z軸導(dǎo)軌面距離短，大大減少翻轉(zhuǎn)力矩，提高剛性。主軸采用模塊化設(shè)計(jì)，多種功能模塊供客戶選擇，適用多種類型加工。
※ X/Y/Z軸選用C3進(jìn)口滾珠絲桿，兩端固定支撐，采用無(wú)齒輪隙增扭矩同步帶傳動(dòng)，輸出扭矩大，移動(dòng)速度快，加工性能好；預(yù)拉伸結(jié)構(gòu)，采用高精度大接觸角精密軸承支撐，具有極高的移動(dòng)精度和極佳的熱穩(wěn)定性。


The machine adopts gantry fixed beam frame structure, which can keep good rigidity and precision for a long time. It has large torque and good dynamic characteristics. According to the processing demand, it fully absorbs the international advanced machine tool design concept. 

Key parts including the lathe, column, beam, wagen, ram, workbench, etc., are made of high strength resin sand, high strength and qualified cast iron, which can withstand heavy cutting and maintain long-term accuracy and high stability.

Thermally symmetric headstock and high-precision angular contact bearings are mounted on the head and tail of the spindle, effectively ensuring rigidity and accuracy. The spindle with enlarged diameter and thickness is adopted to further enhance rigidity. The spindle is driven by high-power motor with high power and high torque, which can achieve high-precision heavy cutting even at low speed.

The feed system adopts ball screw with enlarged diameter and pre-stretched, which can increase the rigidity of the screw and effectively prevent the thermal deformation of the screw.

Screw and chain automatic chip removal structures are combined to ensure smooth chip removal.

X/Y axis adopts imported heavy load linear guide rail, Z axis adopts rectangular hardened plastic guide rail, low wear, high load, to ensure the long-term usage of machine tool precision, and significantly improve the cutting precision and rigidity.

The distance between the center of the spindle and the guide surface of Z axis is short, which greatly reduces the turning torque and improves the rigidity. The spindle adopts modular design with a variety of functional modules for customers to choose, and id suitable for various types of processing..

The X/Y/Z axis adopt C3 imported ball screw, and both ends are fixed and supported. It also uses gearless torque increasing synchronous belt transmission with high output torque, fast moving speed, and good machining performance. Pre-tensile structure, supported by high-precision high-contact angle precision bearings, with high movement accuracy and excellent thermal stability.
