Factors affecting machining accuracy of cylindrical grinder


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 spindle deviates from the center line of the headstock and tailstock. When grinding the end face of the shaft shoulder, it will cause the perpendicularity error between the end face of the shaft shoulder and the axis of the workpiece. When grinding the outer circle, it will affect the surface roughness and produce spiral wear lines.

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

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
