Drilling machine operation procedures

1. Before working, it is necessary to comprehensively check whether the operating mechanism of each part is normal, clean the rocker arm guide rail with fine cotton yarn, and inject oil according to the brand of lubricating oil. 2. The operation can only be carried out after the rocker arm and each part of the headstock are locked. 3. There shall be no obstacles within the swing range of the rocker arm. 4. Before drilling, the worktable, workpieces, fixtures and cutting tools of the drilling machine must be aligned and fastened. 5. Select the spindle speed and feed correctly, and do not overload. 6. When drilling beyond the worktable, the workpiece must be stable. 7. When the machine tool is in operation and automatic feed, it is not allowed to change the speed. If the speed is changed, it can only be carried out when the spindle is completely stopped. 8. The loading and unloading of cutting tools and the measurement of workpieces must be carried out during the shutdown. It is not allo

Practical function of drilling machine

Drilling machine is a universal machine tool with a wide range of applications, which can drill, ream, ream, spot facer and tap thread. When the drilling machine is equipped with process equipment, it can also carry out boring. When the drilling machine is equipped with universal worktable, it can also carry out drilling, reaming and reaming.  Basic classification of drilling machines Drilling machine is a machine tool mainly used to process holes (such as drilling, reaming, reaming, tapping, countersinking, etc.) on the workpiece. Machinery manufacturing and various repair factory essential equipment. According to the use and structure, it can be divided into the following categories. vertical The worktable and headstock can move vertically on the column, which is used to process small and medium-sized workpieces. Desktop It is called bench drill for short. A small vertical drilling machine, with a maximum diameter of 12-15mm, is installed on the bench. It is mostly used f

Brief history of drilling machine development

图片
Drilling machine refers to the machine tool that mainly uses the drill to process holes on the workpiece. Generally, the rotation of the bit is the main motion, and the axial movement of the bit is the feed motion. The structure of the drilling machine is simple, and the machining accuracy is relatively low. It can drill through holes and blind holes, replace special tools, expand, countersink, ream or tap. In the process of machining, the workpiece does not move, the tool moves, the center of the tool is aligned with the center of the hole, and the tool rotates (main motion). The characteristic of drilling machine is that the workpiece is fixed and the cutter rotates. In the early 1970s, drilling machine was controlled by common relay in the world. For example, the mega50 of Eldorado company in the United States, the t30-3-250 of TBT company in Germany, the b4-h30-c / L of Nagel company, and the DEG type drilling machines of shinzaki advanced precision manufacturing Institute in Japan

Factors affecting machining accuracy of cylindrical grinder

图片
1. The influence of the equal height of grinding head, headstock and tailstock on the dimensional accuracy of workpiece. The equal height error of grinding head, headstock and tailstock will make the center line of headstock and tailstock deviate from the axis of grinding wheel spindle in space. At this time, the workpiece surface will be a hyperboloid. grinding machine 2. The influence of the parallelism error of the axis of the grinding head spindle in the horizontal plane on the dimensional accuracy of the workpiece is analyzed. When this error occurs, the shape of the workpiece produced by the CNC cylindrical grinder will be a cone, that is, the grinding wheel grinds at an angle, and there are spiral grinding lines on the surface. Grinding Machine, Cnc Lathe, Sawing Machine 3. The influence of Perpendicularity Error of grinding head movement relative to machine tool guide rail on machining accuracy is analyzed. The final result of this error is that the axis of the
