Reaming is the processing of cast or drilled holes on the workpiece by reaming drill with porous drill machine, which is used to enlarge the hole diameter and improve the processing quality of holes. Reaming can be used as the finishing process of holes with lower requirements, or as the pre-processing process before dumpling holes. Compared with twist drill, reaming drill has the following characteristics: (1) High accuracy, small surface roughness because of small cutting depth, narrow chips, easy discharge,...

According to the functions of common parts on combined machine tool, they can be divided into the following categories. (1) Power components. Power component is a general component used to transfer power and realize working motion. In order to provide main motion or feed motion, it is the main general component of modular machine tools and their automatic lines. It includes power sliding table, power box, uniaxial head with various technological properties (such as milling head, drilling head, boring head,...

Porous drilling machine considers that the load of the machine is larger and the speed is lower when it works. The load is smaller and the speed is higher in fast forward and fast backward. In order to save energy and reduce heating, dual pump or variable pump should be used in the pump source system. Pressure-limited variable displacement pump with pressure feedback is adopted. In the hydraulic system of small and medium-sized special machine tools, throttle valves or speed...

                Vertical drilling machine is widely used in practical applications, but in the process of processing must pay attention to the use of safety matters. 1. Before driving, we must check carefully according to the inspection points and lubricate according to the lubrication chart. Check whether the lubrication parts of the vertical drilling machine are in good condition, whether the cooling system is normal, whether the rocker arm is in zero position, whether...

The following points should be paid attention to when choosing the type of self feeding drilling machine according to different conditions: 1.What is the diameter of the borehole? 2.What is the depth of the borehole? 3.What is the material of the workpiece to be processed? 4.What is the way to install it? Horizontal, vertical, upright or oblique. 5.What is the speed (cutting speed) requirement? 6.What is the required voltage? The standard is 3 phase 380V, 50Hz. 7.What is the form...

Modular machine tools refer to special machine tools based on serialized and standardized general components with a small number of special components. It is suitable for processing one or more processes of one or several similar parts in mass production. The modular machine tool has the characteristics of simple structure, high productivity and high degree of automation. Modular machine tool generally use multi-axis, multi-tool, multi-process, multi-facet or multi-station simultaneous processing mode, the production efficiency is several times to dozens of...
