TX4240型双柱座标镗床是在我厂生产了二十多年的老产品T4240型双柱座标镗床的基础上发展起来的新产品。老产品座标定位精度靠精密丝杠(新标准六级) 配合丝杠校正尺来保正,精度可达0.005mm。定位时大数出普通标尺读出,5 mm以内及小数靠刻度盘配以游标读出。这种结构有其实用性,但读数不直观,操作者会因所站位置的不同而产生视觉误差,操作过程中计算错误也会造成废品,因机械磨损还会降低座标定位精度。
TX4240 double column coordinate boring machine is a new product developed on the basis of the old product T4240 double column coordinate boring machine which is produced by our factory for more than 20 years. Old product positioning accuracy by precision screw (the new standard six) with screw calibration ruler to protect the accuracy of up to 0.005mm. When positioning a large number of ordinary ruler read out, less than 5 mm and decimal by the dial with the cursor read out. This structure has its practicality, but the reading is not intuitive, the operator will have different positions because of the visual error, the calculation error during operation can also cause waste, because of mechanical wear and tear will reduce the positioning accuracy of coordinates.
