Drilling machines are units for processing and drilling holes. They are used for countersinking, cutting, drilling, carving, as well as other types of processing parts of the product. The main tools used in drilling machines are taps, drills, countersinks, and other types of cutters.
The principle of operation of this equipment is the rotation and translation of the tool along a certain axis. Drilling machines, depending on their features, can be divided into classes: horizontal drilling, vertical drilling, boring, central and multi-spindle. At the same time, they are subdivided according to the processed material. There is equipment for processing and drilling metal, stone, plastic, wood, glass, etc.
The most common vertical drilling machines. Their distinctive feature is that the spindle is located vertically, while the workpiece is mounted on the table of the machine itself. Aligning and Aligning the Tool with the Partoccurs by moving the part around the table. They are used for machining and drilling small parts. Found widespread in equipment repair shops, as well as in the manufacture of small batches of products.
To process parts that are large, horizontal drilling machines are used. In them, the part is fixed motionless, while the alignment of all machined holes occurs by moving the spindle. They are used for machining and drilling large holes.
Multi-spindle drilling machine is used to process parts with multiple holes. Its characteristic allows the processing of several holes at the same time. There are models with fixed and adjustable spindles. Centering machines are needed for drilling and processing holes in the end face of the part. These machines are equipped with cutters to remove parts before centering.
To perform multiple functions, there are models that can perform milling, drilling, cutting operations. These are aggregate or combined devices, which include a cutting, boring, milling drilling machine. The price for it depends primarily on the number of tasks performed. Programming modern equipment allows you to reduce the cost and time for processing all holes in parts, while increasing the quality of work.
In its design may bea device for supplying a special coolant to the surface. These fixtures are attached to drilling machines during the processing of hard materials, which is done to avoid damage and overheating of the tool. The main technical characteristics of the equipment are the power of the machine, the maximum drilling size, the possible depth of the hole, the spindle stroke along with its speed, the overall dimensions of the table and workpiece, the dimensions and weight of the entire machine, the spindle taper.
