SAFETY INSTRUCTIONS FOR
WORK ATVERTICAL - DRILLING MACHINES

Getting Started:

It is necessary to put your clothes in order, fasten the cuffs of the sleeves, pick up the hanging ends of the clothes, put on a headdress; women are obliged to put their hair under a scarf, tied without hanging ends;

Examine your workplace, remove everything from under your feet and from the aisles, work on a flat, dry floor;

Provide adequate lighting for the workplace.

Tool health check:

For transverse drilling on the machine, center drills (center, centur), feather, (spoon), twist drills for metal and wood, cork drills, countersink drills (countersinks), countersink drills, and awl drills are used.

Make sure that the drill is selected according to its purpose and diameter, according to the quality of sharpening, along the length of the cutting part.

The drill should not be bent along the axis, the shank should be smooth, without nicks, dents with a length sufficient to secure it in the chuck.

If a drill is used for metal, then it is necessary to change the sharpening angle by 60 - 80 0; more Better conditions cutting has a drill for metal, sharpened as center - with a center and road workers - undercutters.

The axis of the guide center must coincide with the axis of the drill.

The cutting edges must be sharpened at the same angles and have the same dimensions.

The cutter sizes must be the same.

There should be no bluing on the blades.

Checking the availability and serviceability of devices and fences.

Use cartridges only with a smooth shape; it is forbidden to use cartridges with protruding and uncovered bolt heads.

It is impossible to work on a drilling machine without a drill guard; in the working position, the guard should cover the remaining part of the drill, and as the drill exits the hole in the workpiece, it should guard the entire drill.

It is impossible to work on the machine if the belt drive is not protected.

Before starting the machine, it is necessary to inspect the starting device and grounding for their integrity. The switch must be closed with a blind casing, not start buttons drowned. The starting device of the machine should be located conveniently, not far from the machine operator, with the calculation of turning the machine on and off from the main working position. In progress:

Fix the part firmly on the machine

When processing curved parts, use templates and fixtures for attaching them to the table

It is forbidden to aim details at cutting tool hands

Do not pick up a drill that flies out on the go

Do not stop the chuck by hand after turning off the machine

When processing long or wide materials, an auxiliary table or racks with frames should be installed;

Do not remove safety guards;

It is allowed to work only on a working machine;

Nothing can be transmitted or received through the machine while it is running;

Do not clean, lubricate, adjust and repair the machine on the go, as well as measure near the cutting tool;

The workplace must be kept clean, it must not be cluttered up and passages to it;

It is forbidden to store workpieces on the machine table, finished goods, tool, rags, etc.;

Finished products and workpieces should be laid stably, using spacers;

When laying boards in rows, spacers or other measures are used to ensure complete stability of the rows; the height of row laying should not exceed 1.5 m;

In the event of a sudden interruption in the supply of voltage and in case of any, even a short-term absence, it is necessary to immediately turn off the machine;

Upon completion of work:

Stop the machine; start cleaning after the cutting tool stops rotating. Chips and sawdust are removed only with a brush, brush or whisk;

Any observed malfunction or danger must be reported to the administration.

II. Types of marriage and ways to eliminate them.

III. Adjustment of a vertical drilling machine.

Work on the machine can be done according to marking, stops and templates;

Adjustment when working on marking consists in choosing a drill, installing it in the spindle chuck and starting the machine

o the size of the drill is determined either according to the drawing of the part, which indicates the diameter of the hole, or directly from the sample;

o the type of drill is selected depending on the size of the hole and the direction of the wood fibers; so, for example, a blind shallow hole with a diameter of 30 mm with a flat bottom should not be drilled with a twist drill with a conical sharpening, for this case a drill with a circular undercutter should be used; for drilling into the end face, a drill with a circular undercutter is of little use.

o for fastening drills, the spindles of drilling machines are equipped with universal three-jaw chucks that allow the use of drills with tails of various diameters;

o it is necessary to fix the drill in the chuck only with the help of special key, since fixing it by hand is not enough, the drill will rotate and move in the chuck during operation, which will damage its shank and chuck jaws

o after installing the drill in the chuck, you must make sure that the axis of the drill coincides with the axis of rotation of the spindle (the drill does not hit), for this it is enough to turn the spindle of the machine with the drill fixed in the chuck manually. In the case of significant radial runout, it is necessary to release the drill and try to clamp it in the chuck in a position in which the radial runout will be the smallest and acceptable. A drill with an unacceptable radial runout must be replaced with a new one.

o when marking holes on a part, first determine their centers at the intersection of two mutually perpendicular lines; prick the centers of the holes with an awl and, releasing the spindle, without turning on the machine, align its center with the center of the hole with a light touch of the drill; then release up the spindle; at the same time, with the left hand (with manual control) or with both hands (with pedal control), they hold the part on the table, in the position pressed against the stop (ruler); then repeat the drilling technique; it is advisable to use the drilling depth limiter available on the machine;

o if it is required to drill several holes according to the marking, located at the same distance from the edge of the part, a guide should be used (Fig. 1); the working surface of the ruler 1 is located from the axis of the spindle 2 at a distance "a", equal to the distance of the center of the holes from the edge of the product 3.

Drilling on stops.

It is carried out under mass production conditions, when it is required to drill several holes in a bursk-type part with final dimensions, located at the same distance from its edge and having the same diameter.

o for this purpose, a device is used (Fig. 2), consisting of a long bar 1 attached to the guide ruler of the table. Spring stops 2 are fixed on the bar. The location of the stops on the ruler can be changed depending on the distance between the holes in the part. Spring stops can be pressed out and hidden in the longitudinal groove of the bar 1.

o a guide ruler with a bar attached to it is installed on the machine table in such a way that the distance from the spindle axis to the supporting surface of the bar is equal to the distance from the center of the holes to the edge of the product 4. The distance of the first spring stop to the spindle axis (measured along the supporting surface of the bar) must be equal to the distance from the center of the extreme hole to the end of the part. The position of the remaining stops relative to the first one depends on the distance of the corresponding hole in the part from the first hole;

o drilling holes without marking using pre-installed stops is carried out in the following sequence: the part in which a groove of holes of the same diameter is to be drilled is placed on the machine table, pressed with the base edge and end to the supporting surface of the bar and the first stop; having drilled the first hole, move the part along the bar to the second stop, pressing the first stop with the edge of the part into the groove of the bar; basing the part, as in the first case, along the supporting surface of the bar and the stop, drill the remaining holes.

o if you need to get through, and blind holes, set the caliper travel limiter on the machine to the required drilling depth;

o it is necessary to ensure that chips do not accumulate on the machine table, as they can get between the support surface of the bar and the edge of the part, and this will lead to wrong location holes; chips should be removed with a brush or compressed air, directing its jet along the supporting surface of the bar.

Drilling on templates.

Performed in cases where it is necessary to obtain several holes located at different distances from the edge of the part, if the part has the shape of a shield, frame, etc. holes of two or more sizes are drilled in several steps;

The template is a shield 1 (Fig. 3) several bigger size than detail. On the front side the template for basing the part on three points, the stops 2 are reinforced, two - for a longer edge of the part, one - for a shorter one. On the underside of the template there are holes, the diameter of which is equal to the diameter of the fixing pin fixed in the machine table coaxially with its spindle. The number of holes in the template corresponds to the number of holes to be drilled in the part, and their location relative to the base stops corresponds to the location of the holes. To increase the service life of the template, holes are made in metal plates embedded in the template and reinforced with screws;

Drilling according to the template is carried out in the following sequence: the part is placed on the template, basing it on three fixed points; install the template with the part so that the fixing pin of the table enters one of the holes in the template. After making sure that the template is properly fixed, start drilling the hole; the rest of the holes are drilled in the same way. Often the template holes are connected to each other with grooves in order to move the template from hole to hole without lifting (removing from the pin) the template from hole to hole.

Having removed the machined part from the template, it is replaced by another. Drill holes in the second part in the reverse order, without making unproductive movements of the template on the machine table;

In the first machined part of each new batch, it is necessary to check the correct location of the holes, since during the operation and storage of the template, the position of the stops may be violated.

IV. Checking the accuracy of vertical drilling machines.

The vertical drilling machine is periodically checked for accuracy, guided by the accuracy standards given in the table below:

A serviceable and properly configured machine provides the following machining accuracy: axis drilled hole should be parallel to the side and perpendicular to the lower base surface of the bar. The deviation must not exceed 0.15 mm over a length of 100 mm.

5.4 Take off overalls and put them in the closet.
5.5 Wash face and hands with warm water and soap.
5.5 Report to the work manager about all the shortcomings noticed during the work, and the measures taken to eliminate them.

When working on a drilling machine, there may be a risk of injury to the worker from chips or flying fragments, the workpiece when it is loosely fixed, when touching a rotating drill, chuck or machine spindle. When installing the workpiece on the table of the drilling machine, it is necessary to securely fasten it with a vice, conductors and other devices so that the workpiece does not move during processing under the action of the cutting tool and does not spring. Do not support the workpiece directly with your hands during processing. Only particularly heavy parts and large sheets can be installed on the machine without fastening. When drilling small parts, they can be held with pliers.

When installing a part in a clamping vice, it is necessary to select them in proportion to the parts and check their serviceability. The vise must be fastened to the machine table with bolts, the heads of which must be sized according to the groove of the table; it is also possible to fasten parts with clamping bars, stops, etc.

When installing the drill, it is necessary to check the serviceability of the drill shank and the shank at the adapter taper sleeve, the cleanliness of the spindle taper hole and the surface of the tool entering the spindle or the adapter taper sleeve c. tool, as well as the strength of fastening in the tool spindle (drill, reamer, tap). If the drills are installed in a chuck with protruding set screw heads, then the chucks must be closed with smooth round casings.

The drill is removed from the chuck only when the machine is completely stopped. To remove the drill from the spindle, use a special wedge that must not be left in the groove of the spindle.

Before starting the machine, it must be removed from the table unnecessary tool and the remaining fasteners, bring the emulsion cooling pipeline to the tool and check if anyone is in danger of turning on the machine, remove the gloves, as they can be twisted by a rotating drill.

Cleaning chips in the form of a twisted spiral should be done with a hook or brush. It is unacceptable to remove and brush off the chips with your hand. During operation, do not stand on the line of chips coming out of the machine. It is necessary to monitor the serviceability of the cutting tool.

When processing parts on radial drilling machines, when approaching a traverse with an inserted drill to the drilling site, it should be fixed using the clamping handles available on the machine. It is not allowed to accelerate on the caliper traverse in order to avoid its falling out of the guides.

After drilling is completed, before the lifting mechanism is started, the traverse is released from the clamps and retracted to the side.

Tool blunting (drills, reamers) or improper sharpening can cause breakage and jamming of the tool in the workpiece. In this case, the work on the machine must be stopped.

When drilling with manual feed, do not press hard on the drill to avoid breaking it. A countersink or drill must be fed to the part, gradually increasing the depth of cut. Otherwise, during a sharp feed, a part or a cutting tool may be torn out, which is a danger to both the worker and others.

During the operation of the machine, it is impossible to carry out: installing a drill or other tool in the machine chuck, checking the sharpness by hand cutting edges tool and hole depth and exit of the drill from the hole in the part, removing chips by hand with cutting edge tool, cooling the drill with wet ends or a rag held by hand, and also work in mittens. During operation, it is forbidden to bring the emulsion cooling pipeline to the tool or fix it, change the machine, correct the installation of the part on the machine, clean and lubricate the machine.

Changing the tool while the machine is running is only allowed with a special quick-change chuck. When replacing a tool on multi-spindle heads, where the replacement is associated with the presence of the worker's hands in the area of ​​\u200b\u200bthe heads, it is necessary to use a special stand that prevents the head from falling.

In the designs of multi-spindle drilling machines, special devices are provided for starting and switching off each spindle. If one spindle is used in the job, the rest must be turned off. Vertical drilling and radial drilling machines are equipped with devices that prevent spontaneous lowering of the traverse, trunk, bracket. When working with center drills, if automatic chip removal is not provided, it is removed from the drilled hole only after the drill stops and retracts. Do not blow chips out of drilled holes with your mouth.

At the end of the processing of the part, it is necessary to turn off the drilling machine, remove the tool, unfasten the part and remove it from the table or machine plate, clean the machine and the workplace from chips.
