Briefing upon hiring

The machine operator must undergo training upon hiring and each time immediately before starting to operate the machine. The employee conducting the training must focus on the important features of working with the equipment.

Each machine operator must pass certification and receive permission to work before official employment. The instruction is a standard document. It is drawn up according to certain rules, certified by the signature of the head of the enterprise, and stamped.

Important aspects of safe operation of a drill press:

You cannot start work without undergoing training and completing documents.
The job description must contain the basic requirements for the performance of work.
A beginner must undergo training before starting work.
Employee knowledge should be systematically tested. Even those who are highly qualified and have been working in their specialty for many years.
Each employee must sign in a special journal. It confirms that you have completed the training.

Safety requirements before starting work

What you need to do before starting to work on the drilling machine:

Wear special protective clothing - a robe or apron with sleeves, as well as a headdress (beret, headscarf).
Check that the belt drive housing is securely fastened.
Make sure that the protective ground is securely connected to the machine body.
Firmly fix the drill in the chuck.
Run the machine idle to check the serviceability of the starting box by pressing the buttons.
Securely secure the part on the machine table in a vice. Do not hold the part with your hands while drilling.
Wear safety glasses.

Fixing the workpiece

When fixing a polished workpiece, place pads under the jaws of the vice.

When fixing the workpiece in the vice of a drilling machine, the machine plate should be raised, thereby reducing the distance from the workpiece to the drill to 2-3 cm. Do not forget to fix the fixing screws for adjusting the height of the drilling machine plate. Otherwise, the slab may fall down during drilling. Which will lead to breakage of the twist drill, damage to the workpiece and even injury.

Safety during work

To avoid injury while operating the drilling machine, do not:

place foreign objects on the bed;
lower your head close to the drill;
put on gloves and work in them;
lubricate and cool the drill with a wet cloth: this can only be done with a special brush;
try to stop the chuck or drill with your hands;
leave the machine without turning it off.

Safety precautions when working on a drilling machine include the following rules:

Do not use drills with worn taper shanks.
It is necessary to smoothly feed the drill to the part after the machine spindle reaches full speed.
Before you start drilling the workpiece, you should tilt the centers of the holes. Wooden parts need to be pinned with an awl.
When the drill leaves the workpiece, you need to reduce the feed.
When working with large pieces of wood, you need to place a small piece of plywood or a board under the part.

Safety precautions when drilling metal

Hello readers and blog visitors. Drilling metals is just as dangerous as cutting metal, and it also has its own secrets and subtleties. This is what I decided to write about today.

Twist Drill Selection

More often, when drilling metals, we use twist drills with individual sharpening of the cutting edge. And here it is important to observe safety precautions when drilling certain parts and workpieces.

It will be better if you always have at hand a set of twist drills for both wood and metal, of various diameters and lengths.

I recently bought myself a set of drills like this. Not a lot, of course, but it was enough for my purposes. And it's quite inexpensive.

Install a twist drill of the required diameter and length into the chuck of a drill press or electric drill.

When attaching the drill, make sure that the drill is installed clearly vertically, without any distortions.

When using small diameter twist drills (

To securely fix the drill, wrap 2-3 layers of thin copper or brass wire around its shank.

This trick will allow you to increase the diameter of the shank and securely fix the drill in a standard ordinary chuck.

Marking blanks

When marking workpieces, it is necessary to establish the exact position of the center and the required dimensions of the hole. This can be determined using a marking square, a caliper or a regular ruler.

To make the markings more visible, apply them with a center punch or permanent ink. The markings will fall into the drilling area and no traces will remain. Before drilling, it is better to mark the center of the intended hole with a center punch.

This reduces the risk of the drill moving to the side.

Fixing the workpiece

After marking, before drilling a metal workpiece, it is necessary to fix it in a regular bench vice or in the vice of a drilling machine.

Drilling the workpiece

Using the levers located on the body of the drilling machine, move the drill evenly towards the workpiece.

Some machines are equipped with a liquid/oil supply to the drill to avoid overheating and breakage of the drill, as well as fusion of the edges of the workpiece (if it is plastic). In this case, you need to ensure the correct supply of fluid to the drill/drilling point.

In any case, even if the machine is not equipped with an automatic fluid supply system, it will not be superfluous to cool the drill , including when working with a hand drill.

This can be done by periodically pouring water from a bottle on it, or by lowering the end of the drill into a container of water.

Articles - Safety precautions when cutting rolled metal

Metal is used as a structural material much more often than other materials. However, it is extremely rare for a metal workpiece to be found in the form required for further operation. To give rolled metal the desired shape, it is cut, chopped, filed, straightened and many other different operations are performed on it.

Due to the fact that metal (in particular steel) has quite significant strength characteristics, significant effort is required to manipulate the workpiece. This effort must be applied in doses, in the right direction, and most importantly, follow safety measures.

In this article, SkladMetal specialists will talk about how important safety precautions are when processing metal at the domestic and professional level.

In general, to work safely with metal you will need:

gloves or mittens
Eye protection goggles or mask when working with open flames and sparks
respirator, which is especially important for enclosed spaces
Closed clothing if possible
- headdress
working tools (faulty ones greatly increase the risk of injury)

Depending on what technological operation you will perform and with what tool, the specified “security set” may change somewhat, but not much.

It is important that there is a first aid kit in the immediate vicinity of the work site for possible first aid.

If the work involves significant dust generation, then it is very advisable to equip the workplace with a point supply and exhaust ventilation system. This is necessary so that dust and smoke are removed directly from the place of its formation, without spreading to the entire room.

In some types of metal processing, quite strong heat generation and overheating of the workpiece and the processing tool are observed. Uncontrolled overheating should not be allowed (the tool will deteriorate, the part may fail). This problem can be dealt with by local cooling of the heated zone or by periodic operating cycles.

Safety precautions when cutting metal

In everyday life and small-scale production, sheet and rolled metal products are most often cut with hand hacksaws or a grinder. Cutting with a hacksaw only in appearance seems to be a simple operation. The most important thing in this process is not to warp the canvas and not to press too hard, since in addition to the crooked cut itself, a nuisance may occur in the form of the canvas bursting.

To prevent the bursting of the blade from injuring your hands, you need to wear mittens. It is better to start working with an angle grinder under the direct supervision of a more experienced comrade.

The grinder is a very insidious tool that can cause serious injuries (without exaggeration). The main problem that can occur is disk jamming.

To do this, it is enough to tilt the tool a little or cut with a large feed.

Therefore, you need to cut with a grinder with a minimum feed and only with a disk designed for this type of material. It is absolutely unacceptable to cut metal with “toothed” steel discs (see Fig.

1), no matter how productive they may seem. It is unacceptable to remove the protective cover for supposedly better visual control of the process.

It is better for beginning craftsmen to choose disks with a small diameter (125 mm).

Emergency situations

In the event of an emergency, remember these rules:

If the power goes out, you need to turn off the machine as quickly as possible.
If the unit, drill breaks down, or the housing grounding is faulty, work should be stopped. It is necessary to remove the drill from the part, turn off the equipment and notify the authorities about the breakdown.
If the machine or its individual parts catch fire, you must turn off the unit and immediately extinguish it using sand or a carbon dioxide or powder fire extinguisher.
If one of the employees is injured, you need to provide first aid and report the incident to your superiors. If the injury is serious, the victim should be taken to the hospital.

Auxiliary processes to facilitate drilling

To increase the efficiency and safety of the operation, there are measures to regulate the process.

Cooling

When processing metal, the drill, as well as the material itself, become very hot and can melt. Due to the increase in temperature, the cutting edges wear out faster and the holes are of poor quality.

To combat this phenomenon, cooling emulsions, cutting fluids, and even water are used. The composition can be supplied through channels on the drill. Some machine models provide cooling directly at the processing site.

Hit

This function of the hammer drill is used in finishing work (for drilling holes for sockets, channels for cables), in dismantling walls and ceilings.

The equipment of the device quickly penetrates into hard substrates due to the force of impact. The tip can simultaneously rotate and deliver shocks, destroying the material.

Machine requirements

You can only work on working units. Over time, machine parts become unusable even with proper operation and proper care. They need to be changed periodically. The heaviest loads during equipment operation fall on the chuck and transmission belt. They are the first to fail. Untimely replacement of worn parts worsens the quality of work and increases the likelihood of accidents and injuries.

Drilling machine - dangerous equipment

. When working with it, it is very important to follow safety precautions. Only if you have the appropriate qualifications and excellent knowledge of safety regulations, you can be sure that the operation of the machine will be safe.
