本文对机床通用材料作一评论。对机床用材的各种性能,包括弹性模量、比刚度、阻尼特性、长期尺寸稳定性、抗冷却液的能力、磨损速率、摩擦特性、热传导性和生产周期等进行比较。并举例说明。本文介绍了近六年发展起来的用于高精度机床结构的新型材料-“环氧树脂混凝土”。这种材料具有高阻尼性,高比刚度以及高尺寸稳定性。使用专利模铸技术,可获得价格低廉的高光洁度的构件。精密导轨可铸于结构之中,从而可消除导轨的磨削加工、刮研和稳定化热处理等工序。Cranfield 研究发展股份有限公司现在能向英国用户提供环氧树脂混凝土结构设计和服务。
This article makes a comment on machine general materials. The machine tool material properties, including modulus of elasticity, specific stiffness, damping characteristics, long-term dimensional stability, anti-coolant ability, wear rate, friction characteristics, thermal conductivity and production cycle, etc. were compared. And give an example. This article describes the new material developed for the last six years for high-precision machine tool construction - Epoxy Concrete. This material has high damping, high specific stiffness and high dimensional stability. Using patented molding technology, low-cost, high-finish components are available. Precision rail can be cast in the structure, which can eliminate the rail grinding process, scraping and stabilizing heat treatment process. Cranfield Research and Development Co., Ltd. is now able to provide British customers with epoxy resin concrete structure design and services.
