The 1K62 lathe began to be used at enterprises in the 30s of the last century. It was developed at the factory "Red Proletarian". Initially, this unit was labeled using the abbreviation DIP. The designation used today was assigned to the model after the introduction of a new system of metalworking research institutes in 1937.
Advantages of the 1K62 model
Today, this unit is used quite widely and is considered very high quality equipment. The technical characteristics of the 1K62 lathe are simply excellent. The undoubted advantages of this model include:
- Versatility. On 1K62, you can perform any kind of work, including threading.
- The ability to use for processing workpieces of very hard hardened metal. The spindle of the machine is mounted on bearings of a special design, providing rigidity of fastening.
- High power main drive and the reliability of the assembly of the kinematic motion scheme.
- A wide range of gears and speeds.
- Cutting on the machine 1K62 can be performed including mineral-ceramic, as well as carbide tools.
- Vibration resistance - One of the advantages that distinguishes this metal lathe, having a large weight.
- High precision even when used in drum mode.
Machine feed movement
Model 1K62 belongs to frontal lathes, and therefore, it is mainly used for processing not too long and at the same time overall workpieces.
The device of the 1K62 lathe is practically no different from the device of any other equipment of this group. As a drive in this model, an asynchronous power unit of a short-circuited type with a power of 10 kW is used. The speed of movement of the support and rotation of the spindle is regulated by two separate handles. This is one of the features of the model. In addition to the main one, an additional motor, also asynchronous, with a power of 1 kW is used in the machine. This power unit provides quick movement of the caliper.
Thus, the feed mechanism of the 1K62 machine includes four kinematic chains:
- screw cutting;
- cross cutting;
- slitting;
- accelerating the movement of the caliper.
Front and rear headstock
When the machine is operating, the feed from the main engine is transmitted to the driven pulley, and then through a complex system of couplings and blocks to the front headstock with the spindle. Then the movement is transmitted to the snaffle shaft and to the feed mechanism. The rolling bearings of the shafts of the assembly can be lubricated both by spraying and by force. The design of the model includes a special oil pump.
The tailstock of the 1K62 unit can move along the guide of the bed and is equipped with a plate. Retractable pinol moves with a screw pair and a flywheel. Its departure is fixed by the handle. The housing of the headstock can be shifted relative to the plate in the transverse direction. If necessary, the headstock can also be mounted on the bed. Sometimes a special tool designed to process holes is installed in the nest of pins.
Caliper Model and Apron Mechanism
Metal lathe 1K62 is equipped with a caliper, the design of which includes the following elements:
- lower rails designed for longitudinal movement along the rails;
- a transverse carriage, in the circular guides of which a rotary plate is installed under the cutter slide.
The plate can be clamped at any angle with respect to the spindle. The apron mechanism is located in a housing screwed to the support carriage.The longitudinal movement of the caliper is provided by the rack and pinion, and the longitudinal - by a special screw.
Technical characteristics of the 1K62 lathe: basic parameters
The 1K62 machine can be used including for working with hollow conical parts. This is ensured by the possibility of biasing the workpieces in the transverse direction.
Technical characteristics of the 1K62 machine are as follows:
- part height above the caliper - 224 mm;
- the maximum allowable height of the workpiece above the bed - 430 mm;
- workpiece length - 750-1500 mm;
- the mass of the part fixed in the centers is 460-900 kg;
- the mass of the part in the cartridge is 200 kg;
- forward / reverse spindle rotation speed - 2000/2420 rpm;
- machine weight - 2520 kg;
- dimensions - 2500x1200x1500 mm.
Thus, the technical characteristics of the 1K62 lathe make it very productive and reliable. This model performs well both in high-speed and power cutting. According to the standards provided by GOST, the 1K62 unit can be operated under the conditions of UHL-4.
Cost of equipment
How much can a 1K62 lathe cost? The price for it, as for any other equipment of this type, is quite high. However, its cost is still much less than many imported analogues supplied even from the CIS countries. At the same time, this model is practically inferior in terms of the quality of part processing and ease of use of foreign machines. The used 1K62 machine costs about 1,200,000 rubles. For comparison: the Belarusian model GS526U, which has approximately the same design and technical specifications, is offered for $ 33,200.
Repair of the machine 1K62
The technical characteristics of the 1K62 lathe are good, and it can work for a very long time without repair. But of course, like any other equipment of this group, the 1K62 model requires periodic maintenance. This procedure may include the following operations:
- running in the machine at all feeds and speeds;
- checking parameters for accuracy;
- washing and wiping parts during partial disassembly;
- cleaning dirt and grinding guides in case of wear.
Repair of a 1K62 lathe may consist in performing procedures such as replacing worn out units and mechanisms with new ones or restoring them. External non-working surfaces are usually painted after repair or maintenance. Also, replacement of model enclosures is often performed to prevent contamination of worked surfaces with abrasive dust and chips.
