1K62 can be attributed to the frontal lathes, because. it allows the processing of
relatively short workpieces with a large diameter. The front end of the spindle is
made in accordance with GOST 12593 (Flanged ends of the spindles for the swivel
washer and clamping device flanges) (DIN 55027, ISO 702-3-75) for the swivel
washer, with a centering short cone 1:4 (7°7′30″).
The spindle is mounted on two rolling bearings. The front support is an adjustable
double row roller bearing with an inner tapered ring. The bearing is adjusted by
tightening the nut (stopper), which presses on the inner ring of the bearing. At the

same time, the ring is pushed onto the conical neck of the spindle and unclenched;
thus reducing the gap between the rings and rollers resulting from wear. The rear
spindle support consists of two angular contact bearings, which are adjusted only
during the current inspection of the machine. In the design of the 1K62 lathe,
special bearings are provided for installing the spindle, which ensures the required
rigidity and high accuracy in processing workpieces. According to GOST 8-82, the
1K62 lathe belongs to the H accuracy class. Machining accuracy will be ensured
even in shock load mode. The following steady rests can be installed on the 1K62
lathe: movable, the installation diameter of which is 20-80 mm, and fixed, its
installation diameter is 20-130 mm. The longitudinal movement of the 1K62
machine carriage can be limited by a special stop mounted on the front shelf of the
bed. Thus, with the stop installed, the speed of movement of the caliper cannot
exceed 250 mm/min. To ensure fast movement of the caliper, an additional
asynchronous motor is used. Its power is 1.0 kW at a rotation speed of 1410 rpm.
The machine is equipped with thermal relays that protect the motors from
prolonged overloads, as well as fuses that protect against short circuits. The lathe
can use a three-jaw self-centering chuck with a diameter of 250 mm or a four-jaw
chuck with a diameter of 400 mm.
Desktop drilling n/s 12B
The machine is designed for drilling holes in small parts made of cast iron, steel,
non-ferrous alloys and non-metallic materials in industrial enterprises, repair and
household workshops.
Machine tools NS-12 allow you to perform the following operations:
drilling
reaming
deployment
reaming
threading

Revolving machine 1341
Universal turret lathe 1341 with a horizontal axis of the turret is designed for
turning, boring, countersinking, drilling, reaming and cutting internal and external
threads in mass production. It can process parts made of both bar material in a
collet chuck and piece workpieces in a three-jaw chuck. Processing of parts from a

bar is carried out in an automatic cycle, and piece blanks in a three-jaw chuck - in a
semi-automatic cycle.
The largest diameter of the workpiece processed above the bed - Ø 400 mm;
The largest diameter of turning the workpiece above the upper part of the support -
Ø 380 mm;
Distance between centers - no;
The number of tools in the turret - 16;
Distance from the end of the spindle to the turret - 32..630 mm;
The greatest length of giving of a bar - 150 mm;
Spindle drive electric motor power - 5.5 kW;
The spindle of the machine 1341 receives 8 speeds of rotation in the forward
direction (60..2000 rpm) and 2 speeds in the reverse direction (100, 265) through
the selection gears of the gearbox. To control the enumeration, 4 friction clutches
of the EM-52 type are used, which are automatically controlled by the cams of the
command device or from the control panel of the machine.
Spindle braking is carried out by simultaneous activation of electromagnetic
clutches 1MS and 2MS. The reversing of the shingle is activated by reversing the
electric motor. The front end of the spindle is made in accordance with GOST
12593 (Flanged spindle ends for a swivel washer and clamping device flanges)
(DIN 55027, ISO 702-3-75):
The nominal diameter of the cone D = 106.375 mm, the nominal size of the end of
the spindle - 6

The limits of the number of reverse revolutions of the spindle per minute (2
speeds) - 100, 265 rpm;
Spindle braking by two friction clutches.
The feedbox is directly connected to the spindle without the intermediate gears of
the guitar. At the output of the feed box, there is only a running shaft, there is no
lead screw, so the thread on the machine is cut using a special copier.
The feed box mechanism makes it possible to obtain 16 steps of longitudinal feeds
(10 of which are repeated) 01..1.6 mm / rev and 16 steps of transverse (circular)
feeds (11 of which are repeated) 0.03..0.48 mm / rev .
To control the enumeration of the feed box, 2 friction clutches of the EM-32 type
are used, which are automatically controlled by the cams of the command device
or from the control panel of the machine. Machine accuracy class H.

On a universal milling machine, using a universal dividing head, you can mill
spiral grooves on cylindrical parts, as well as perform various milling operations
related to turning a part by a given amount.
Electrical equipment is mounted in a spacious niche. Table feed management is
separate. There are protective devices that protect the worker from chips and
splashes of coolant. The cooling system is equipped with quick-detachable sumps.

Calculation of the level of automation of technological equipment.
The calculation will be made by the tabular method according to the time indicator
dT for all subsystems of the GPU for all the functions they perform.
Let's take the value of the indicator of the level of automation:
for "automatic" function execution - dT = 1.0;
for "automated" function execution - dT = 0.5; for "manual" function execution in
a subsystem - dT = 0. Let's determine the average value of the automation level
indicator for each of the GPU subsystems and for the entire production (Table 2 -
8).
