Line for Bright Steel
RG-Finishing Line for Bright Steel
The production line for bar-to-bar bright bars of consists of an RG-HCT peeling machine, RJE two roll precision straightening machine, pre-straightening machine, beveling machine and centerless grinding machine, with the first two pieces of equipment as its key machines. This production line is capable to machine bars with diameters from 10 to 160mm.
This production line processes hot-rolled, finish forged and heat treated black bars into bright ones with bright surface and better dimensional tolerances.
Applicable bar materials include bearing steel, gear steel, spring steel, free cutting steel and Ti alloys.

The bar-bar line is capable to machine straight bars and thick wall tubes with large diameters. Each piece of equipment on the line can function individually; therefore, the application of the line is multi-fold:
- Both-end beveling and pre-straightening of hot rolled black bars
- Both-end beveling, pre-straightening and peeling of black bars
- Both-end beveling, pre-straightening, peeling and precision straightening of black bars
- Both-end beveling, pre-straightening, peeling, precision straightening, and sizing and beveling of black bars
- Both-end beveling, pre-straightening, peeling, precision straightening, sizing and beveling, and grinding of black bars
The combination of machines on the line can be modified to meet specific technical requirements.
