由于模板平行度好，变形小和使用线性导轨，可有效保护模具。
Mold protection thanks to precise platen parallelism, minimal platen deflection and linear guides.
如果齿条固定，小齿轮装在工作台的轴承上，而工作台所在的导轨与齿条平行，那么小齿轮的轴转动时，就会带动工作台平行齿条而移动。
If the rack is fixed and the pinion is carried in Bearings on a table guided on tracks parallel to the rack, rotation of the pinion shaft will move the table parallel to the rack.
定位精度很重要，如同线性导轨的平直度和平行性一样。
Location precision is very important, just as the flatness and parallel of linear guide rail.
针对高层建筑电梯安装过程中导轨垂直度与平行度的要求，设计了一种新型的激光准直系统。
In view of the requirements of the verticality and parallelity in the process of equipping elevator for high building, a new laser collimating system is presented.
板上下运动的导向靠两侧导轨，导向效果较好，保证了上下工作面的平行度。
The guide for the hold-down plate moving up and down is near to the lead rails in two sides. The good guide effect ensures the parallelism of upper and lower working sides.
它通常是由经过充分正火或时效处理的灰铸铁或者球墨铸铁制成。它是一个坚固的刚性框架，所有其他基本部件都安装在床身上。通常在床身上有内外两组平行的导轨。
It usually is made of well-normalized or aged gray or nodular cast iron and provides a heavy, rigid frame on which all the other basic components are mounted.
