锯切速度曲线是不可变的，但进给速度曲线随进给机构杆长比的不同而变化。
The sawing speed curve is unchangeable, but the feed speed curve can be different with different length ratio of members of the feeding mechanism.
框锯机锯切工件表面加工质量在很大程度上取决于进给速度和锯切速度的匹配关系。
The quality of the workpiece surface is subject to the matching relation between the feed speed and the sawing speed to some large extent.
本机采用水平锯切进给方式，直线导轨作导向，同时采用气液转换器来保证锯切速度平稳。
The machine adopts horizontal feeding and takes linear guide rail as direction, and adopts air-liquid convertor to assure stable cutting speed.
