JG-1012CM

龍門型高精度治具研磨機

機器特性∶

JG-1012CM龍門型高精度治具研磨機，底座及橫梁采用花崗巖構件所組成的結構體，主要是利用花崗石的特性，震動阻尼良好、動態特性佳，大大改善加工件的表面光度，此外，花崗巖的熱傳薄導系數低，受熱源及大環境溫度變化影響小，故能維持機臺的穩定度，提升加工件精度穩定性，而且花崗巖不生銹、耐酸堿，無須特別保養 。

JG-1012CM（X/Y/W）三軸馬達與精密高速滾珠螺桿采直結式傳動，增強剛性及提高精密度。

采用C1 級精密滾珠螺桿，螺桿作3°℃C溫升伸長量預拉，有效提高剛性降低軸向負荷變形。

FANUC控制器：31-B

X/Y/Z/W移動行程∶（1000×1000x250x400 mm）床臺平面度 ≤ 0.01 mm

（X/Y/Z）三軸采用重負荷NSK（P4超精密級）滾柱型線性滑軌，軌道面寬 45 mm，滑塊滾柱與軌道接觸面精大，軌道接觸面彈性變形量小、強度大、吸震系數高。快速移位X/Y/Z軸24 m /min。

Z軸進給采用線性馬達作為動力傳輸，主要是利用線性馬達的特性，高聲應性、直驅傳動高剛性，且具有高速、高加速度性、無背隙誤差等，不但簡化化Z軸結構，而且大幅提升工作效率，實現高速、超高精度的加工。

JG-1012CM 結構體設計，增加兩層德制裂防震墊材質，隔絕內、外部的震源，確保加工件高精度的品質。搭配高頻研磨主軸，提升研磨加工效率。

定位精度（X/Y/Z）∶±0.0025 mm 

重復精度（×/Y/Z）∶±0.002 mm

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
