Do not obstruct established aisles.

Remember that the equipment you are servicing is a source of increased danger. The sharp edges of parts, tools and chips can cause cuts to the hands if they accidentally come into contact with them, and their surfaces that heat up during processing can cause burns. Chips generated during machining can cause serious eye injuries. Moving and rotating parts of the machine can also injure. The cause of injury can be a fall due to a slippery floor (doused with oil, emulsion, etc.).

Shorting live electrical circuits through a worker's body to ground can cause electric shock.

To protect against the action of hazardous and harmful factors, work in personal protective equipment: a cotton suit, leather boots and goggles.

About all cases of equipment malfunction discovered by you, as well as accidents that you have witnessed or that have happened to you, immediately inform the foreman or the person replacing him. Report serious injuries to the medical center. Provide first aid to the victim.

Get your goggles ready.

Check the presence and serviceability of protective guards, as well as current-carrying parts of electrical equipment, grounding devices, and chip protection devices.

Check the gap between the edge of the hand rest and the working surface of the grinding wheel, it should be no more than 3 mm.

Before starting work, rotate the tool at idle at operating speed for the following time in minutes, at least:

circles with a diameter up to 150mm - 1 min.
over 150 to 300 mm - 2 min.
over 300 mm - 3 min.

Arrange tools and accessories in a convenient order for use.

Report equipment malfunctions to the foreman immediately: do not start work until the malfunctions are eliminated.

3. Safety requirements during work.

Install and lower the abrasive tool only after the machine has come to a complete stop.

When working with manual grinding and portable pendulum tools, as well as cutting and peeling machines with manual feed, the working speed of the circle should not exceed 80 m / s.

It is forbidden to work with the side (end) surfaces of the circle, if it is not intended for this type of work.

When the circle diameter decreases due to actuation, the frequency of its rotation can be increased, but without exceeding the operating speed allowed for this circle.

Bring the object to be sharpened to the circle smoothly, without bumps. Press the circle effortlessly.

Do not allow the rotating wheel to be braked by pressing on it with any object.

Editing of circles is carried out only with ruling tools.

Polish and grind small parts only with the use of special tools and mandrels that exclude the possibility of injury to the hands.

Do not lean on the machine during operation and do not allow others to do so.

Beware of burrs on workpieces.

Be sure to stop the machine and turn off the motor:

when leaving the machine even for a short time;
during a temporary stoppage of work;
during a power outage;
when cleaning, lubricating, cleaning the machine;
when a problem is detected.

All work related to the electrical equipment of the machine must be carried out in cooperation with electrical specialists.

4. Safety requirements in emergency situations.

If the machine fails, or voltage appears on the case, the machine should be turned off and the master should be informed about the malfunction.

Extinguish fires on equipment with an electric drive only with carbon dioxide fire extinguishers. In other cases, it is possible to use water and foam fire extinguishers.

Before providing first aid for mechanical injuries, wash your hands with soap or lubricate with iodine. Do not touch the wound and the surface of the dressing applied to it with your hands. Do not clean the wound from blood clots and other inclusions, do not wash it even with medicines. Disinfect the edges of the wound with iodine and apply a bandage, gauze or handkerchief moistened with iodine.

For burns, apply a dry antiseptic dressing to the affected area.

In case of electric shock, if the victim cannot break away from live parts, turn off the electrical installation. If you know how to do this using improvised non-conductive means, disconnect it from the installation, or cut (or break) the electrical wiring with a tool with dielectric handles. In case of respiratory distress, start artificial respiration using the mouth-to-mouth or mouth-to-nose method. In case of cardiac arrest, perform an indirect heart massage by pressing on the left side of the chest at a frequency of 60 times per minute, alternating massage with artificial respiration.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>
