The radial drilling machine, WD-Z3040×12A, is a versatile machine with a wide range of applications, it has reasonable speed of revolution,it can be use on work pieces for drilling, expanding, raming, spot-facing, tapping and other operations. Equipped with suitable accessoriesk it can also be used for boring operation. It may be used in machine shops for serial production or single-piece production. Feature     1. The spindle speed and feed change are affected by their eparate machine levers, and therefore easily and accurately conrtrolled. 2. The cutting depth is controlled by the drill depth stop. Thus the drill can automatically stop. 3. The spindle head and the arm as well as column are reliable clamped by means of clamping mechanism, which makes easy maintenance possible. 4. The spindle head movement and the arm rotationg are light and quick 5. The arm is raised and lowered by a couple of gears. The arm elevating unit is provided with mechinical and eletrical safety. 6.The guideways of the arm, the outer and inner cloumns are wear-resistant for long service life.
