On October 28, 2019, stage 2 of the project for the production of rolls for roughing stands of sheet rolling mills with a diameter of more than 1000 mm was completed. and production of large-tonnage rolls for large-section and rail-beam mills.

A high-performance milling machine with CNC model 1K675.01F3x8000 designed for turning sheet-rolled and coarse-grained rolls, including making rhombic and lentil slices on a barrel, was commissioned. The design of the machine provides a complete set of two turning calipers. Each caliper is equipped with two side tool holders for processing rolls according to the program. Tool holders are fully integrated into the CNC program. Type of CNC system - SINUMERIK 840 Dsl.

Roller mill produced by PJSC KZTS (Ukraine), meets all modern standards of machine tool industry. Along with the highest precision machining, a stable design, reliability and durability come to the fore.

This equipment is unique because it combines the functions of roughing and finishing machining, as well as the ability to process the roll with two calipers at the same time. When performing roll turning on a machine 1K675.01F3h8000, the time for machining is reduced by 40%, unlike standard technology.
This machine allows the machining of large rolls for beam and large mill, as well as work rolls for roughing stands of sheet rolling mills with a diameter of more than 1000 mm. from ductile iron, high-speed and hypereutectoid steels.
The main technical characteristics of the equipment:

  • Max diameter of the workpiece is 1850 mm;
  • Max load capacity up to 70,000 kg;
  • The distance between the centers of 8000 mm;
  • Processing is carried out by a modern CNC system;
  • Processing of parts simultaneously with 2 calipers;
  • Device for slicing rhombus and lentils.
