Product Description

The STK-GZ50 Fully Automatic Hydraulic Steel Bar Cutting Machine is engineered for high-volume cutting of round steel bars used in automotive parts, machinery manufacturing, metalworking and industrial component production. It combines a hydraulic cutting mechanism, servo-controlled material feeding, automatic loading and PLC control to support continuous bar cutting with reduced manual handling.

The machine is suitable for processing medium-carbon steel, selected alloy steels and stainless steel within the specified material and diameter limits. With a 6-meter automatic loading rack, programmable cutting operations and automatic separation of finished parts from material ends, the STK-GZ50 offers a practical solution for manufacturers producing repeated lengths of round steel bar stock.

Key Features and Benefits
1. Fully Automatic Material Feeding

The STK-GZ50 uses a servo-driven feeding system to position steel bars for cutting. Equipped with a 1.8 kW servo motor, the feeding system coordinates material movement with the programmed cutting cycle. Its maximum single feeding stroke is 720 mm. The machine is designed to process one bar at a time, making it suitable for repeated cutting operations involving individual round steel bars.

2. Hydraulic Cutting System

The machine incorporates a hydraulic cutting mechanism powered by a 22 kW main motor. The hydraulic system provides the force required to cut compatible steel bars within the machine's specified operating range. The cutting arrangement is intended for repetitive industrial production where stable operation and consistent workpiece handling are important. The appropriate cutting die and setup must match the material grade and bar diameter.

3. Automatic Loading Rack

The standard configuration includes a 6-meter automatic material rack, allowing raw steel bars to be prepared for repeated feeding and cutting operations and reducing the need for manual positioning between cycles. The rack is suitable for processing raw material lengths of up to 6 meters, according to the supplied machine specifications.

4. Automatic Material Separation

The STK-GZ50 supports automatic discharge of cut pieces and separation of leading and trailing material ends. This helps organize finished products and reduces manual sorting requirements. The technical configuration specifies a remaining material tail length of approximately 30 mm under the stated operating arrangement. Actual material utilization should be evaluated according to the cutting length and feeding configuration.

5. Touchscreen and PLC Control

The machine uses a touchscreen interface and PLC control system. Operators can manage the cutting process through the control interface, while the PLC coordinates the required machine operations. This configuration supports repeatable cutting cycles and simplifies routine operation.

6. Production-Oriented Cutting Capacity

The documented cutting rate is 25–40 cuts per minute. Actual production output depends on material properties, bar diameter, cutting length and operating conditions. For manufacturers processing large quantities of similar parts, automatic feeding and cutting can reduce repetitive manual operations.

Industrial Applications
Automotive Parts Manufacturing

The STK-GZ50 can prepare round steel bar blanks for automotive component manufacturing. Typical applications include raw material preparation for shafts, pins, bushings and other machined metal parts. The machine is particularly relevant when large quantities of similar-length blanks are required.

Machinery Manufacturing

Machinery manufacturers frequently process steel bars before turning, drilling, milling and other machining operations. Automatic hydraulic bar cutting can be used as an initial material preparation process for compatible round steel components.

Hydraulic and Mechanical Components

Round steel bars are commonly used as starting materials for hydraulic fittings, mechanical connectors and precision-machined components. The STK-GZ50 can support blank preparation when the material specifications and required lengths fall within its processing range.

Alloy Steel Processing

The machine supports selected alloy steel materials, including 40Cr and 42CrMo, within the specified diameter limits. These materials are used in mechanical components where strength and wear resistance may be important. Cutting suitability depends on the material condition, hardness and approved cutting die configuration.

Industrial Metalworking

Metalworking facilities processing repetitive batches of round steel bar stock can use the STK-GZ50 for automatic cutting and material handling. Its hydraulic cutting mechanism and automatic feeding system are intended for production environments where repeated cutting operations are required.

How the STK-GZ50 Cutting Process Works
  1. Raw material is placed on the automatic loading rack.
  2. The automatic feeding system transfers a steel bar into the cutting position.
  3. Once the material reaches the programmed position, the hydraulic cutting mechanism performs the cutting operation.
  4. The finished section is discharged, and the feeding system prepares the remaining material for the next cycle.
  5. The process continues according to the configured production requirements, with material ends and finished pieces separated through the machine's discharge arrangement.
Choosing the Right STK-GZ50 Hydraulic Bar Cutting Machine

Before selecting the STK-GZ50, manufacturers should confirm the following information:

  1. Round bar material grade.
  2. Bar diameter and material hardness.
  3. Raw material length.
  4. Required finished cutting length.
  5. Production volume per shift.
  6. Cut-face quality and dimensional tolerance requirements.
  7. Downstream machining or processing operations.

These details help determine whether the machine is suitable for the intended application.
