JG-1012CM

龙门型高精度治具研磨机

机器特性∶

JG-1012CM龙门型高精度治具研磨机，底座及横梁采用花岗岩构件所组成的结构体，主要是利用花岗石的特性，震动阻尼良好、动态特性佳，大大改善加工件的表面光度，此外，花岗岩的热传薄导系数低，受热源及大环境温度变化影响小，故能维持机台的稳定度，提升加工件精度稳定性，而且花岗岩不生锈、耐酸碱，无须特别保养 。

JG-1012CM（X/Y/W）三轴马达与精密高速滚珠螺杆采直结式传动，增强刚性及提高精密度。

采用C1 级精密滚珠螺杆，螺杆作3°℃C温升伸长量预拉，有效提高刚性降低轴向负荷变形。

FANUC控制器：31-B

X/Y/Z/W移动行程∶（1000×1000x250x400 mm）床台平面度 ≤ 0.01 mm

（X/Y/Z）三轴采用重负荷NSK（P4超精密级）滚柱型线性滑轨，轨道面宽 45 mm，滑块滚柱与轨道接触面精大，轨道接触面弹性变形量小、强度大、吸震系数高。快速移位X/Y/Z轴24 m /min。

Z轴进给采用线性马达作为动力传输，主要是利用线性马达的特性，高声应性、直驱传动高刚性，且具有高速、高加速度性、无背隙误差等，不但简化化Z轴结构，而且大幅提升工作效率，实现高速、超高精度的加工。

JG-1012CM 结构体设计，增加两层德制裂防震垫材质，隔绝内、外部的震源，确保加工件高精度的品质。搭配高频研磨主轴，提升研磨加工效率。

MODEL:JG-1012CM DOUBLE COLUMN JIG GRINDER 

Feature:

JG-1012CM double column Jig Grinder with superstructure fabricated by granite, which is well-known by its excellent damping, low heat conductivity, rust-proof, and corrosion resistance, is capable of stabilizing the machine accuracy and enhancing the roughness on workpiece.

Stiffness and accuracy is also enhanced with the motors on three axis(X,Y,Z) direct-driven design transmission.

C1 grade ballscrew was adopted, pre-tension by 3℃ in temperature increment, which is ffectively upgrading stifness and preventing fom deformation during operation. 

FANUC contrller:31i-B

X,Y,Z,W travel:1000X1000X250X400mm 

Plate Flatness ≤ 0.01 mm

NSK P4 heavy load ultra precise linear guideway withrail width of 45 mm is adopted in3 axis(X,Y,Z)and has a wider engagement in order to a low deformation, high strength, vibration resistance as well as capability of max feed speed of 24 m/min.

Feeding movement of Z axis is diven by linear motor, which features instrument with hyperresponsiveness, rigidity, high speed,excellent acceleration, and no backlash and not only simplifes the superstructure but also fufils rapid and precise machining process.

Stifness and accuracy is also enhanced with the motors on three axis (X,Y,W) direct-drven design transmission.

Besides, the two additional German-made vibration insulation pads are also incorporated inside to assure the accuracy and quality. Postionaccuracy:±0.0025 mm Repeatabiliy:±0.002 mm
