Hydraulic Radial Drill

The hydraulic rocker drill is a type of drilling equipment used for processing holes. It belongs to the family of rocker drills.

Hydraulic Radial Drill

This equipment is suitable for drilling, hole enlargement, reaming, planing, and tapping of medium and large parts. Boring can be performed under various process conditions.

Additionally, this operation is both convenient and efficient, and has a wide range of applications.


  • The hydraulic rocker drill utilizes a hydraulic pre-selection shifting mechanism to save auxiliary time.
  • The spindle can be reversed, parked (braked), shifted to neutral, and more, all of which are controlled by a handle with light operation.
  • To maintain the stability of the rocker drill precision and prolong its service life, the rocker arm guide rail, outer cylinder round surface, main shaft, main shaft sleeve, and inner and outer column rotary raceways are all quenched.
  • Effective measures have been taken in the structural design and manufacturing process of the hydraulic rocker drill to significantly extend its precision and service life.
  • Perfect safety protection devices and outer column protection are in place.
  • The headstock box, rocker arm, and inner and outer columns feature a hydraulically driven diamond-shaped block clamping mechanism for reliable clamping.

The hydraulic rocker drill boasts high working efficiency and minimal machining error, making it a popular choice for drilling, enlarging, reaming, boring, and tapping of large and medium-sized parts. It plays a significant role in the machine tool industry.

However, what are the potential issues that we should be aware of when utilizing this equipment?

Precautions for the use of hydraulic rocker drill

When drilling with a hydraulic rocker, do not use gauze to remove iron filings, and do not use mouth blowing or hand wiping. Instead, use special tools and brushes.

The operation of the rocker drill should follow the “three goods” principle (good management, good use, good repair) and the “four knows” principle (know how to use, maintain, check, and eliminate faults).

Strictly follow the lubrication chart of the hydraulic rocker drill to carry out refueling, achieving the “five fixed” principle (fixed timing, fixed point, fixed quantity, fixed quality, and fixed staff). After filling the oil, be sure to cover the lid.

Before drilling, loosen the locking device when finding the position of the workpiece. Adjust the extension length of the infeed spindle according to the drilling depth, and then lock the locking devices.

When adjusting the automatic drilling of the drilling depth, first make contact with the workpiece, and then adjust the feed collision block to the required depth value and lock it.

The operator must pay attention to the sharpness of the tool and should not continue to use a blunt tool to avoid accidents.

Adjust the height of the hydraulic rocker drill properly during work and do not make it too high. During the machining process, clamp the rocker arm and the headstock.

After work, place the handles in the non-working position. Park the headstock close to the column, lower the rocker arm properly, and then cut off the power supply.

Ensure the firm loading of the workpiece. When drilling through the hole, place the block on the bottom pad; otherwise, the device may be drilled.

During the drilling process of the hydraulic rocker, do not stop the drill until the drill bit is fully retracted from the workpiece. When reversing the turning, wait for the spindle to stop before starting again.

When loading or unloading the workpiece or fixture, remove the cross arm, and be cautious of the surrounding people and objects to avoid collision accidents.

If the equipment has been parked for more than eight hours, run it at low speed for five minutes after starting to ensure that the lubrication system is unblocked.

Be aware of the possibility of overload during work. If the fuse is detached or making a sound, stop the automatic feed immediately and eliminate the overload.

When stopping the drilling speed, make sure to stop it before shifting gears. It is strictly prohibited to stop the shifting gear during operation, as it may damage the gears inside the gearbox.

The personnel operating the hydraulic radial drill must be familiar with the equipment’s structural performance and obtain independent operation permit after passing the examination.
