Application:

The Radial Drilling Machine Model Z3080×20 Z3080×25 which has a wide range of application, are suitable for drilling, counter-boring, reaming, spot-facing and tapping on large and medium size object. It has many strong points as follows: The key parts were adopted high strength cast iron and special steel, this make it has more stability. It is more durable also because it is processed through first-class technic. After the continuous treating by specialized equipment, it guarantees the basic parts have excellent quality. The hydraulic pressure system tightens each parts greatly. 16 range of spindle turning speed for your choice, it makes it drills highly effectively. All the hydraulic control equipments concentrate in the headstock, which facilitates the operation greatly. Novel design of outward appearance and painting demonstrate the time style.
