The film tells about the work of VNIIMETMASH on the development and implementation of hot and cold rolling methods at enterprises to obtain blanks close in size to the part itself.
Testing mechanical engineering products for deformation.
Disadvantages of the mechanical engineering industry.
For example, insufficient automation, high labor intensity, large amounts of production waste.
The concept of rolling.
Until recently, only large products, plates, rails, sheets, and strips were rolled.
The work of Academician A.I. Tselikov made it possible to obtain a blank close in size to the part itself.

Developers are reviewing drawings of new equipment.
Automated part-rolling mills.
The method of hot screw rolling of parts with variable diameters.
Samples.
Mill operation. 200 rods per hour pass through compression rolls.
The rods are turned into 200 long double parts.
Cut in half, they are turned into 400 car axle shafts.
One mill reliably provides a large conveyor production line of an automobile plant with axle shafts.
Assembly of cars on the plant line.
Production of shafts for gearboxes.
Rolled waste is minimal.
A steel blank is turned into a worm shaft.
Product samples.
After heating the middle part of the blank in a ring reducer, rolling is carried out by three rollers with parallel axes.
The creation of a worm from start to finish is demonstrated.
The operation time is 12 seconds.
A special feature of the process is the automatic reversal of the roller rotation.
The worm is so precise that an allowance is left only for grinding.
At the First State Bearing Plant, a mill with screw gauges rolls blanks of bearing balls from a steel rod.
The operator controls the mill.

Rolling line for blanks of bearing rings.
A piercing mill turns a heated cylindrical blank into a sleeve.
Without additional heating in rolls with screw gauges, blanks of roller bearing rings are rolled from it.
Quality control of the resulting rings.
Product samples.
The rolling method in screw gauges is used to manufacture axles for plate chains of various conveyors.
