矿物铸造矿物铸造的产物是矿物铸件，是一种面向未来的环保材料，作为机器的结构件，以其价格和性能的优势在某些应用方面可以替代传统的铸铁。

矿物铸造（Mineral casting）人造花岗石以天然花岗石碎料、下脚料为主要原料，加入环氧树脂为辅料，经过混合搅拌、振动密实而制成的新型矿物铸造产品。

它是一种替代铸铁但优于铸铁的新型节能、环保结构材料——非金属合成材料。

主要特点：1、复杂外型的成型能力和整合性能力由于不同与传统铸铁的工艺流程和材料性能，采用常温铸造，可以用矿物铸件浇铸出各种传统铸铁无法浇铸的复杂外型，也可以用特殊的胶粘结矿物铸件的方式实现更复杂的外型，从而得到理想的外型。

矿物铸件具有极强的整合能力，可以把诸如传送切削液的管道、型体、导轨、线缆、油管、气管、联接件等浇铸入矿物铸件中，例如在制作机床机座的过程中，机床的导轨安装板可以直接与矿物铸件浇铸在一起，浇铸完成后可以对导轨安装板进行铣、钻等机加工，使安装面达到要求（甚至在某些高精的矿物铸造过程中，铸件的特定的表面可以直接作为导轨的安装面）。

矿物铸件具有和钢铁相似的热膨胀系数，可以和铸入矿物铸件中的材料很好地整合在一起。

矿物铸件的整合性能，使用户省去很多的装配和机加工时间，极大地提高了用户的生产效率、和经济效益。

2、高精度矿物铸件的热收缩性很小，而且不存在局部收缩，比传统的铸铁精度要高很多，很多场合矿物铸件是一次成型不需要机加工。

即使要实现更高的精度时，也可以很方便地进行铣、磨加工，就可以达到要求。

提高了被加工工件的精度。

3、吸震性矿物铸件的吸震性要比传统的铸铁强10倍，特别是对大幅度的震动，矿物铸件具有极强的吸震能力。

马达的震动以及在搬运途插车对矿物铸件的震动影响极小，可以很好地保证机器的精度。

使用矿物铸件做机座的机床，在使用过程中的震动对机座几乎不产生影响，从而保证了机床的精度。

提高的加工工件的精度。

4、热稳定性矿物铸件对温度的变化不敏感，导热性比金属要低很多，有效地把机床因受热引起的几何尺寸误差控制在最小，从而保证了机床的精度。

VT (μm/min)
The MWSS “wear” is the distance u in the cutting direction. The wear rate, or cutting speed, is hence & = du dt . The total volume of wear or removed u material is from geometry Vu = K ⋅ L ⋅ u (Fig. 3). The volume-wear rate, or Material Removal Rate (also noted & = dV dt = K ⋅ L ⋅ u &. MRR) is V u u
vT =
π D
2 K
bPvf
(4)
This MWSS wear law expresses the proportionality between the table speed vT and the product P.vf under permanent regime. Experimental verification of (4) is illustrated in Fig. 4. This result is perfectly in line with recent work on multi-wire sawing [6, 7].
