CNC Steel Bar Saw Shear Cutting Line — New | GUTE, Chengdu, China

The GUTE CNC Steel Bar Saw Shear Cutting Line (Model SJT50) is an intelligent processing system that integrates automatic sawing, upsetting, threading, and polishing of steel bars into a single continuous production line. Raw bar is fed, sawn, upset, threaded, and ground in sequence, with the entire rebar sawing–upsetting–threading–port grinding process operable by just one person, with an additional operator optionally configured to receive finished material.

This significantly reduces labor intensity and improves workplace safety compared to running these as four separate manual operations. As a practical example, using double-end threading on 9-meter, 32mm rebar over an 8-hour shift, a single operator can process 1200–1500 thread ends — approximately 20 tons of steel bar processing capacity per shift.

Why Choose an Integrated Sawing & Threading Line?

Rebar coupling (used to join long lengths of reinforcing bar with threaded mechanical splices rather than lap welding or overlapping) requires precise sawing, upsetting (thickening the bar end to compensate for thread depth), threading, and grinding — traditionally four separate operations requiring multiple machines and operators. GUTE's integrated line combines all four processes into one production system, dramatically reducing the labor and floor space required while improving consistency across every processed bar end.

With sawing diameters from 16mm to 50mm and transmission speeds up to 50m/min, this line is built for high-throughput rebar coupling production, serving fabricators and contractors who need to process large volumes of rebar for mechanical splicing on major construction and infrastructure projects.

Frequently Asked Questions

What does this machine actually do?
It integrates four processes — sawing, upsetting, threading, and grinding — into one continuous production line, preparing rebar ends for mechanical coupling/splicing.

What rebar sizes can this machine process?
The line handles sawing diameters from 16mm to 50mm, with threading diameters from 16mm to 40mm.

How many workers does this machine require?
The full sawing-upsetting-threading-grinding process can be operated by one person, with an optional second operator to receive finished material.

What's the production capacity of this machine?
As an example, processing 9-meter, 32mm rebar with double-end threading, one operator can produce 1200–1500 thread ends per 8-hour shift — approximately 20 tons of steel bar processing capacity.

What raw material lengths does this line accept?
The line accepts raw material up to 12m in length, producing sawn sections from 1.5m to 12m.

Is financing or staged payment available?
Yes. A deposit secures your order and begins production, with the remaining balance due only once your machine has been built, inspected, and is ready to ship.

Should I buy new or used?
This model is available new, backed by CE and ISO 9001:2000 certification.
