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 for manual drilling, and is often used to process small holes of small workpieces.
Rocker type
The headstock can move on the rocker arm, the rocker arm can rotate and lift, and the workpiece can be fixed. It is suitable for processing large, heavy and porous workpieces, and is widely used in mechanical manufacturing.
Deep hole drilling machine
The specialized machine tools that use deep hole drill to drill holes whose depth is much larger than the diameter (such as the deep holes of gun barrel, barrel, machine tool spindle and other parts), in order to facilitate chip removal and avoid too large machine tools, are generally horizontal layout, and are equipped with coolant conveying device (input coolant from the inside of the tool to the cutting part) and periodic tool withdrawal chip removal device, etc.
Vertical Band Saws
Vertical metal band sawing machine (G5325x65x750)
Vertical metal band sawing machine (G5360x160x600)
Vertical metal band sawing machine (G53)

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
