    CXN 系列 - 高阶精密型


    ★ 轨道方式使用线性滚珠循环式,哥德式弧型构槽在本体的上、下滑轨面,各由双孤槽构成,单槽移动的钢球是二点接触的架构,双弧槽总共四个接触点,因此构成坚固的滑轨结构
    ★ 传动方式-滚珠螺杆,透过钢珠在螺帽与螺杆之间做滚动接触,其定位精度与寿命较高,具备高速正逆向的传动及变换传动等特性
    ★ 材质-不锈钢(耐腐蚀,耐热)

    Multi-point repeated positioning accuracy

    ♦   Accuracy measurement description

    1. Unidirectional positioning accuracy: within the range of the predetermined detection stroke, starting from a starting position, moving and positioning in a certain direction sequentially, and detecting the actual
    The difference between the movement value and the target movement value, and the maximum error value is taken. This value is the unidirectional positioning accuracy.
    2. Multi-point repeated positioning accuracy: within the range of the predetermined detection stroke, when the mechanical program is executed, the position accuracy obtained by repeatedly running the same program code
    degree. Calculate the position deviation that occurs when the same position is repeated back and forth, and obtain the deviation value between the two.

    ♦   Precision introduction

    1. Design the GMT high-level precision inspection method to meet the precision requirements of fiber coupling and semiconductor manufacturing process.
    2. The detection of GMT high-end precision linear slide module series adopts multi-point repeated measurement, that is, multi-point quantity measurement within a fixed stroke range (points
    The amount is increased or decreased according to the length of the stroke), and the actual change of the round-trip position error is recorded, in pursuit of high precision and repeatability.
    3. Through the non-contact laser interferometer measurement, to ensure that the unidirectional positioning is within 10μm, and the multipoint repetitive positioning accuracy is within 1.5μm. If there is a need for higher precision and precision, please contact the regional sales/business team.

     

    Axis Definition

    GMT has defined different axis as the following figuration according to the movement direction:

    Horizontal movement direction is X and Y axis.

    Vertical movement direction is Z axis.

    Movement around X, Y, Z axis is defined to α axis, β axis, and θ axis.

    Green arrows present the specified axis movement direction.
