素形材.1991,2(46) 当所生产的铸件数量很小或进行试验研究时,都尽量不用传统的熔模铸造法,因为熔模铸造的生产周期长、压型费用高。若使用切削蜡,就能不用压型,而用机加工的方法加工蜡模。切削蜡在切削过程中,蜡屑不会填入刀沟也不会粘附,所以能象切削金属那样以较高的进给速度进行切削。切削蜡具有良好的切削性,但也有一个固有的缺点,它 .1991,2 (46) When the production of small quantities of castings or pilot studies, try not to use the traditional investment casting method, because the investment casting cycle of production, compression and high cost. If the use of cutting wax, you can not press type, and the use of machining methods wax mold. Cutting wax In the cutting process, the wax will not fill the knife groove will not stick, it can be as cutting metal at a higher feed rate for cutting. Cutting wax has good machinability, but also has an inherent disadvantage of it
