In machining to CFRP material has many important problems, about necessary of high-precision machining, improvement of tool life and dispose of cutting chips etc. Especially in case of twist drill almost cant collect under 0.5 μm cutting chip, the fine-cutting chips diffuse into the sliding table and spindle head with the machine. Moreover, the fine-cutting chip is mixed and diffuse into the atmosphere. The possibility to remarkable decline of working efficiency so the dust-collection provision technology is wished. It is important also from the viewpoint of keep safety of a worker and work environment preservation because the CFRP utilizes in market for industrial structure materials, is increasing. As one method of solving this problem which aspirates and ejects cutting chip from a penetration hole through outside in the central part of the drill shank the new tool and cyclone type dust-collection system were developed. These technologies were used for perforate of CFRP material, and investigated about the cutting characteristic of the hollow type drill, and the effect of work environment improvement to dust-collection performance of cutting chips. As the result, our development machine tool and cutting tool can collect approximate 99.5% cutting chip.

The development of a virtual axis cutter grinder was introduced. The main contents of this paper include layout design, parameters design method, control system and program system. The purpose of the development of the parallel machine tools is for cutter grinding. The dimension of the cutter and the translation workspace for cutter grinding usually is small and is therefore suitable for the parallel machine tool application. The new machine tool has high rigidity and good precision.

In order to improve the machining efficiency of the duralumin turbine rotor of maglev molecular pump, this paper proposes a new double-spindle horizontal milling machining center structure. Through a brief introduction to other types of machine tools, describes the characteristics of this new machine tool and symmetrical machining implementation. This paper proposes a new double-spindle horizontal milling machining centers so that the machining efficiency of duralumin turbine rotors is improve 100% more than that of the traditional machine tool in theory. Moreover, its machining accuracy get relative improve as the decrease of the dividing accumulative error. At the same time, the cost of workpiece is reduced greatly.

The process of designing any new machine tool consists of several stages during its prototype development. Once the cutting envelope and power requirements have been defined, the major structural components are usually designed simultaneously by several different designers, as a result of project time constraints. Because designers may sometimes have a difficult time knowing what impact their changes might have on the completed machine, they need to optimize each of their components separately. In theory, this approach should lead to a possibility of only minor component changes at the point when the complete machine is structurally analyzed. The optimization of each major component is a function of several defined sets of criteria, such as total weight and stiffness (both static and dynamic) under different types of load and boundary conditions. By establishing these criteria, the effectiveness of changes can be evaluated at different times of the machine’s development and optimization. When taking this design approach, it is safe to assume that complete machine tool structures, composed of optimized components, will not only have good static and dynamic characteristics, but also should be cost effective, as the total iron mass will be at a minimum for each component. Results of this process will be shown thru described component optimization changes of an actual new machine design from it’s concept, assembly and final testing.

Currently, the construction of machine tool foundations is a complicated and lengthy procedure with a limited flexibility. In this paper, we present a novel system for constructing machine tool foundations that replaces the need for concrete or concrete-polymer hybrids with a low melting point (LMP) alloy. The system uses a hot bath method to maintain the LMP alloy grouting in liquid form. A fixing device is used to control the embedded depth and positional accuracy of the foundation bolt assembly. The grouting material is injected into the foundation pit by a filling device. This can be extracted from the foundation pit in a later stage with the aid of a recycling device, enabling new machine tool foundations to be manufactured by reusing the LMP alloy grouting material. A prototype was built to test the proposed design. The results show that the system can construct machine tool foundations in a single application, without the delays associated with concrete-based construction, lowering both the economic and environmental cost.
