The ball screw shaft part of the shaft is typical of one of the parts is difficult to process, the current CNC machining parts with high precision is required to solve such a circular arc surface, the most effective processing tapered threaded surface and the cylindrical surface methods. Aiming at the characteristics of round threaded shaft, analyzed the methods and procedures CNC lathe machining parts, and gives a complete NC program. Program is produced in Dalian CKA6132 CNC lathe written.
This paper developed a high efficiency, simple to use and reliable, strong practicability of model 6120 diesel particulate filter regeneration control pulse inverse blow system. The pulse counter blowing regeneration test, and post-processing of particles back down to do the further research. The experimental results show that this device can wall honeycomb ceramic filter for filtering and counter blowing regeneration test and research.
In view of the present diesel filter problem of air pressure and flow control, and designed a new type of filtration and reverse blowing control system, implements the filtration, regeneration of transformation. Using the computer as the core of the whole control system. Pressure regulation of electric valve control is implemented through the filter pressure feedback. The experimental results show that the control system has good steady-state performance, improve the efficiency of the filter.
To strengthen the roof beams of a model duplex composite mold design process, for example, to explore the data in the IMAN UG design platform using three-dimensional solid steps, and introduces a three-dimensional solid design and development of applications for three-dimensional solid design in contemporary mold enterprise business without machining and assembly diagram programming situation.
