GocMakSan / GMS Rebar Bending and Cutting Machines

Manufacturing Heritage of GocMakSan / GMS (Turkish Industrial Production Since 1960)

GocMakSan Makina Sanayi ve Ticaret began its industrial engineering journey in 1960 when a mechanical workshop in Turkey initiated the development of specialized structural construction implements.

Through more than sixty years of continuous development, the enterprise grew into an internationally recognized builder of high-performance metalworking machinery, marketing its products under the trademark GMS (GocMakSan).

Today the company operates modern production facilities in Turkey that unite advanced multi-axis CNC machining, vacuum thermal hardening, and automated assembly bays, exporting heavy rebar machinery to construction contractors across more than one hundred countries worldwide.

Headquartered in Turkey, GMS adheres to strict structural standards across all production operations.

Rigid metallurgical testing of forged drive gears, computerized verification of electrical automation circuits, and thorough load endurance tests guarantee uninterrupted operation under harsh site conditions.

GMS bending and cutting machines perform vital roles in infrastructure megaprojects, commercial foundation development, and modular structural component manufacturing across global markets.

Kinematics and Structural Design of GMS B and BS Series Turntable Benders

Electromechanical rebar bending machinery of the GocMakSan / GMS B and BS series is engineered around an enclosed ductile iron reduction drive equipped with deeply hardened alloy gear trains.

The central working unit consists of a heavy rotating turntable fitted with precision sockets for interchangeable forming pins, mandrels, and guide stops.

The reversible drive operates smoothly in both clockwise and counterclockwise directions, allowing operators to execute intricate geometric bends without manually flipping long structural steel bars.

In the BS series, GMS engineers integrated a dual-position automation mechanism that executes two distinct bending angles within one operational cycle. This dual configuration substantially accelerates the high-volume fabrication of standard stirrups and structural reinforcement hooks.

Operators benefit from straightforward angle setting via a digital control interface with program memory, reducing changeover delays during intensive fabrication shifts.

Mechanical Versus Hydraulic Cutting Technology: Comparing GMS M and H Series

For severing structural rebar, GMS offers two complementary engineering principles: the mechanical M series and the electrohydraulic H series.

Mechanical cutters utilize an oversized flywheel and eccentric crank linkage to deliver rapid cutting strokes of only 0.8 seconds per cycle, making them ideal for high-throughput cutting yards and modular building component plants where speed is paramount.

Conversely, the electrohydraulic H series relies on an internal high-pressure hydraulic pack that drives the mobile blade smoothly through reinforcing steel without frame shock or high acoustic emission.

An adjustable blade clearance mechanism accommodates rebar diameters from 6 to 55 mm, preventing edge deformities and significantly extending tool longevity during heavy work with high-tensile steel grades.

Wear-Resistant Machine Components: Reversible Blades, Bending Pins, and Gear Drives

During round-the-clock site fabrication, machine cutting and forming components absorb substantial mechanical loads and abrasive contact. Reversible blades installed on GMS M and H series cutters are machined from specialized alloy tool steel and feature four ground cutting edges.

When one cutting face wears, the technician rotates the blade block to an adjacent edge, quadrupling overall consumable service life before replacement.

On turntable benders, preventive maintenance focuses on inspecting central pins, guide bushings, and support rollers that encounter continuous abrasive friction from mill scale.

Drive gearboxes require periodic lubrication checks to verify smooth tooth meshing of helical gears and maintain power transmission efficiency throughout years of intense duty.

Specialized Machinery: SL Series Stirrup Benders and SX Series Spiral Rollers

To address specialized fabrication requirements in deep foundation and tunnel construction, GMS developed the SL and SX machine lines.

SL series stirrup benders feature an internationally patented daisy-patterned center pin fixture that maintains precise geometric alignment when shaping closed rectangular and polygonal ties without repeated angle recalibration.

SX series spiral bending units perform continuous roll bending of steel bars from 6 to 40 mm in diameter, producing continuous cylindrical spirals and structural rings with adjustable pitch starting from a 170 mm minimum curvature.

These spiral cages are essential for reinforcing drilled shaft foundation piers, elevated viaduct columns, and underground tunnel structural lining segments.
