Radial drill press

The radial arm drilling machine is a drilling machine in which the rocker arm can rotate and lift around the column, and usually the headstock moves horizontally on the rocker arm. When machining holes on a vertical drilling machine, the centering of the tool and the workpiece is achieved by the movement of the workpiece, which is obviously very inconvenient for some large and heavy workpieces; and the radial drilling machine can be used to move the position of the tool axis. Come to center, which brings great convenience to machining holes on large and heavy workpieces in single-piece and small-batch production.


It can also be called a radial drill. It is a kind of hole processing equipment, which can be used for various forms of processing such as drilling, reaming, reaming, tapping and scraping end faces. According to the clamping structure of machine tools, radial drills can be divided into hydraulic radial drills and mechanical radial drills. Among all kinds of drilling machines, the radial drilling machine is easy to operate, flexible, has a wide range of applications, and is typical. It is especially suitable for single-piece or mass production of hole machining of large parts with porous holes. It is a common machine tool in general machining workshops.


Radial drill press, also known as cross drill. The spindle box can move left and right on the rocker arm and rotate around the column with the rocker arm.

The rocker arm can also be lifted up and down along the outer column to adapt to the processing of workpieces of different heights. Smaller workpieces can be mounted on the table, and larger workpieces can be placed directly on the machine base or on the ground.


Radial drilling machines are widely used in single piece and small and medium batch production to process holes in workpieces with large volume and weight. The radial drilling machine has a wide processing range and can be used to drill various screw holes, threaded bottom holes and oil holes of large workpieces. The radial drilling machine is used to process small and medium-sized holes on heavy workpieces or porous workpieces. It is mainly composed of a base, a column, a rocker arm, a spindle box, and a spindle workpiece table. When the rocker arm drilling machine is working, the rocker arm can rotate around the column, and the spindle box can move radially on the rocker arm. This allows the drill to be aligned with the axis of each hole being machined for hole machining. Use more flexible. Generally, when drilling a workpiece, the workpiece is often clamped on the worktable. When machining large workpieces, the workpiece can be clamped on the base of the drilling machine. Depending on the height of the workpiece, after releasing the locking device, the rocker arm can move up and down along the column, so that the spindle box and the drill head are at the proper height.


Radial drilling machines are generally configured in production occasions such as single-piece mechanical products, small batch production workshops, product assembly workshops, and mechanical repair workshops.


The main variants of the radial drilling machine are the slide type and the universal type. The sliding seat type radial drilling machine is made by changing the base of the basic radial drilling machine into a sliding seat. The sliding seat can move along the guide rail of the bed to expand the processing range. It is suitable for boilers, bridges, rolling stock and shipbuilding, mechanical processing, and other industries. The rocker arm of the universal radial drilling machine can move horizontally in addition to vertical and rotary movements. The spindle box can be tilted on the rocker arm to adapt to the processing of various parts of the workpiece. In addition, there are cart-type, wall-type and digitally controlled radial drilling machines.
