在制木模时,常常遇到圆柱体木模需要两半分开,还有的因工艺的需要十字面开边,也就是加工一个圆柱体本模是分四分之一对出来的。在这种情况下,如果用木车床车出来去掉锯口,其它四分之三就不能用了。这样不但浪费了大量的时间,而且浪费很多木材,要是碰到形状复杂的木模,铲出来就更困难了。 Wooden system in the mold, wood molds are often encountered two and a half need to separate, and some because of the need to craft cross-edge, that is, the processing of a cylindrical mold is a quarter out of pairs. In this case, the other three quarters can not be used if a wooden lathe is used to remove the kerf. This not only wasting a lot of time, but also a lot of waste of wood, if the encounter complex shape of the wooden mold, shovel out even more difficult.
