Radial drilling machines can also be called cross-arm drills. The spindle box can be moved left and right on the rocker arm, and the rocker arm rotates around the column. The rocker arm can also be lifted up and down along the outer column to accommodate workpieces of different heights. Smaller workpieces can be mounted on the bench, 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 medium-small batch production to process holes of large and heavy workpieces. Radial drilling machine has a wide range of machining, which can be used to drill various screw holes, thread bottom holes and oil holes of large workpieces. Radial drilling machine is used to process small and medium-sized holes on bulky workpieces or porous workpieces. It is mainly composed of bases, columns, rocker arms, spindle boxes, and spindle workpiece tables. When the radial drilling machine is working, the rocker arm can be rotated about the column, and the headstock can be moved radially on the rocker arm. This allows the drill bit to be aligned with the axis of each machined hole for hole machining. Use more flexible. When the workpiece is drilled, the workpiece is often clamped on the table. When large workpieces are machined, the workpiece can be clamped on the drilling bed. According to the height of the workpiece, after releasing the locking device, the rocker arm can be moved up and down along the column so that the spindle box and the drill bit are in proper height positions.
Radial drilling machines are generally deployed in production sites such as single-piece mechanical products, small-batch production workshops, product assembly workshops, and mechanical repair workshops.
The main variants of radial drilling machines are the slider type and the universal type. Slide-type rocker drilling machine is the base of the basic type of radial drilling machine is changed into a sliding seat, the sliding seat can move along the bed rail to expand the processing range, suitable for boilers, bridges, rolling stock and shipbuilding, machining, Other industries. The rocker arm of the universal radial arm drilling machine can be used for vertical and rotary motions, and can be moved horizontally. The headstock can be tilted on the rocker arm to adapt to the machining of various parts of the workpiece. In addition, there are car-type, wall-type and digitally controlled radial arm drilling machines.
