How to use a radial drilling machine correctly?

I. Preparations before Startup

Wear protective gear ‌

Wear work clothes, safety shoes and protective glasses

Fasten the cuffs tightly. Do not operate with a scarf or gloves on (to prevent being drawn into the rotating main shaft).

People with long hair must tuck their hair into the work cap

Equipment inspection and cleaning ‌

Check whether the power line is in good condition and the grounding is reliable

Clean the anti-rust oil and impurities from the column, guide rail and the taper hole of the main shaft. After wiping them clean, apply oil for lubrication

Check if the oil level in the oil window meets the standard and if the coolant is sufficient (it is recommended to keep it at around 200 liters).

Tool and workpiece preparation ‌

Check whether the drill bit, reducer sleeve, fixture and other cutting tools are in good condition, with matching taper and no damage

The workpiece should be firmly clamped on the worktable. Small pieces must be fixed with pressure plates or special fixtures. It is strictly prohibited to drill by hand

Ⅱ. Operating Procedures

Adjust position and lock ‌

Loosen the rocker arm and the locking device of the spindle box, move the rocker arm to an appropriate height, adjust the lateral position of the spindle box, and align the drill bit with the processing point

Be sure to relock the rocker column and the spindle box ‌ to prevent displacement during processing and cause an accident

Sets the parameter ‌

Select the appropriate spindle speed and feed rate based on the workpiece material (such as steel, copper, plastic) and the diameter of the drill bit

Soft materials (copper, plastic) can be used at higher speeds

Hard materials (steel) should be selected at low speeds to prevent the drill bit from overheating or breaking

Refer to the recommended parameter table on the machine tool nameplate for setting

Startup and trial run ‌

Connect the power supply, jog the main shaft motor briefly, and confirm that the rotation direction is correct (usually clockwise)

Run it no-load for 1 to 2 minutes and observe if there are any abnormal sounds, vibrations or oil leaks

Start drilling ‌

Start the coolant pump to ensure that the drill bit is continuously lubricated and cooled down

First, gently press the feed. After the drill bit cuts into the workpiece, feed normally

When performing deep hole processing, pay attention to chip removal to avoid iron filings blocking and causing the drill bit to break

When the drill is about to pass through, manual feed should be changed to reduce the feed force to prevent workpiece deformation or drill bit chipping

tapping operation (if applicable) ‌

Lubricate with special tapping oil to reduce friction and temperature

During the tapping process, the left hand stabilizes the spindle while the right hand controls the forward and reverse rotation handle

After inserting the thread, push gently. When approaching completion, reverse and exit to prevent the tap from getting stuck

Ⅲ. Safety Precautions

It is strictly prohibited to change tools, measure workpieces or clean iron filings when the equipment is in operation ‌

Long iron filings must be removed with an iron hook or brush after the vehicle is stopped. It is strictly forbidden to pull them by hand or blow them away with your mouth

When performing automatic feeding, the limit blocks should be set properly to prevent the equipment from being damaged by hitting the limit position

If any abnormality is detected (abnormal noise, smoke, overheating), immediately press the emergency stop button, cut off the power supply and report for repair

During operation, no one is allowed to leave the post. It is strictly forbidden for others to enter the swing range of the rocker arm (±180°).

Iv. Shutdown and Daily Maintenance

After the ‌ operation is completed, ‌

Lift the main shaft and withdraw the drill bit

Move the headstock to a position close to the column, lower the rocker arm to the lowest point and clamp it

Cut off the main power supply and clean the iron filings and coolant

Daily maintenance ‌

Before leaving work every day, wipe the guide rails and lead screws and apply oil to prevent rust

Clean the oil filter screen regularly and replace the coolant once a month

Check if there is any oil leakage in the hydraulic system and whether the electrical joints are loose
