SGS主軸膨脹測量系統SGS4701(Spindle Growth System)專門為高速銑床應用開發。由于加工過程中主軸的高速旋轉和由此產生的熱量,高精密銑床主軸的線性熱膨脹需要被補償,以確保機床的加工精度。德國米銥公司提供的SGS傳感器可以測量機床主軸由于發熱和離心力的作用導致的伸長尺寸。SGS的測量值可以作為修正值直接輸入到CNC機床的數控系統,補償定位誤差。SGS4701測量系統采用電渦流測量原理。正是由于采用了這種非接觸測量原理,使探頭免于磨損。另外,測量過程也免于熱,灰塵和油污的干擾。

SGS4701測量系統包含探頭,探頭電纜和控制器。在出廠時,被校準為適合測量鐵磁性材料或非鐵磁性材料。兩支微型電渦流探頭,可以直接安裝于主軸旁。由于直接測量變形發生的部位,避免了長測量鏈導致的誤差。除了測量位移信息以外,探頭同時可以測得溫度信息并輸出。控制器可以通過法蘭盤被安裝于主軸箱內或直接安裝在主軸內。

德國米銥公司電渦流位移傳感器特點和為客戶帶來的好處:

- 高性價比設計
- 小型化探頭外形設計
- 微型緊湊的控制器
- 可以測量鐵磁性材料或非鐵磁性材料
- 同時測量溫度信息

The displacement measurement system SGS 4701 (Spindle Growth System) has been developed specifically for high speed milling machine applications. Due to high machining speeds and the heat generated, the linear thermal extension of the precision machine tool spindle needs to be compensated for in order to keep the tool in a defined position at all times. The SGS sensor measures the thermal and centrifugal force extension of the spindle. These measurement values are fed into the CNC machine tool as correction values, compensating for any positioning errors. The SGS 4701 operates on the eddy current measuring principle. This non-contact measurement is wear-free. Furthermore, the measurement procedure is resistant to disturbances such as heat, dust and oil.

The SGS 4701 consists of a sensor, a sensor cable and a controller, factory calibrated for ferromagnetic and non-ferromagnetic measurement objects. Two miniature sensors enable it to be installed directly in the spindle, where the measurements take place, typically on the labyrinth-ring of the spindle. As well as measuring linear thermal extension, the temperature of the sensor is also detected and output. The compact controller can be installed on the spindle housing via a flange or directly in the spindle.

Features & Benefits:

    Cost-effective design
    Miniature sensor design
    Miniature, compact controller
    Suitable for ferro- and non-ferromagnetic materials
    Temperature measurement integrated in the sensor
