Semi Automatic Round Steel Bar Peeling Machine Mild Carbon Stainless Alloy 0 - 15m/min Factory Supply

Elevate your metal processing efficiency with our Semi Automatic Round Steel Bar Peeling Machine—engineered to deliver precise, consistent surface peeling for mild carbon, stainless steel, and alloy round bars. With an adjustable feeding speed of 0-15m/min, this machine balances semi-automatic convenience with high productivity, making it ideal for small to medium-sized factories, metal processing workshops, and parts manufacturing plants. It efficiently removes surface defects such as decarburization layers, cracks, and oxidation, ensuring your steel bars meet strict precision and surface quality requirements for downstream production.

• Wide Material Compatibility: Specifically designed to process mild carbon steel, stainless steel, and various alloy round bars. It also adapts to non-ferrous metal bars such as copper, aluminum, and titanium, meeting diverse processing needs in different industries.
• Adjustable High-Speed Feeding: 0-15m/min stepless speed regulation allows flexible adjustment according to bar diameter, material hardness, and peeling requirements. The high-speed setting significantly improves production efficiency, 3-5 times that of traditional processing methods, while the low-speed setting ensures precision for hard alloy materials.
• Semi-Automatic Operation: Combines manual and hydraulic control for ease of use—manual tool adjustment ensures flexibility, while hydraulic clamping and pneumatic-electric feeding/unloading reduce manual labor intensity. Even new operators can master it quickly with simple training, minimizing operational errors.
• Precision Peeling & High Surface Quality: Equipped with high-precision guide rails and a rigid machine frame, ensuring stable operation and uniform peeling thickness (0.5-10mm adjustable). The finished bar features a smooth surface with Ra≤3.2μm, diameter tolerance ≤h9, and excellent roundness, eliminating the need for secondary processing.
• Durable & Low Maintenance: The peeling blade is made of high-hardness 9CrSi alloy steel (HRC 58-62), wear-resistant and long-lasting. The machine body is made of HT300 cast iron, with strong anti-deformation ability and a service life of more than 15 years. Key components (hydraulic pump, motor) are selected from well-known brands, reducing failure rates to ≤5% annually.
• Safe & Reliable: Equipped with emergency stop buttons, protective covers, and pressure protection devices. The machine stops instantly when abnormalities are detected, preventing operator injuries and equipment damage. The closed hydraulic system avoids oil leakage, ensuring a clean working environment.

This semi-automatic round steel bar peeling machine is widely used in various metal processing scenarios, including but not limited to:

• Production of bright steel bars and precision metal parts (automotive parts, bearings, springs, etc.)
• Pre-processing of round bars for machinery manufacturing, military enterprises, and aerospace components
• Surface treatment of alloy steel bars for construction, shipbuilding, and hardware industries
• Recycling and reprocessing of waste steel bars, removing surface defects to restore usability
• Processing of non-ferrous metal bars (copper, aluminum, titanium) for electronics and hardware products

1. Material Preparation: Place the round steel bar on the feeding rack, adjust the guide device to align the bar with the peeling port, and ensure the bar is clamped tightly by the hydraulic clamping device to prevent shifting during processing.
2. Parameter Setting: Adjust the feeding speed (0-15m/min) and peeling thickness according to the material type, bar diameter, and surface requirements. The machine supports parameter memory for frequent processing tasks.
3. Semi-Automatic Peeling: Start the machine—hydraulic power drives the peeling blade to remove surface defects, while the feeding system pushes the bar forward at a stable speed. Manual adjustment of the tool can be done without stopping the machine for flexible adaptation to different bar conditions.
4. Finished Collection: The peeled bar is automatically conveyed to the collection rack after processing. The machine stops automatically when the bar is processed, and the operator can quickly replace the next bar for continuous production.

1. Strong Customization Capability: We support OEM/ODM customization to meet your specific needs—adjust bar diameter range, peeling thickness, motor power, and control system. No MOQ for standard modifications, and we provide one-on-one technical solutions for special processing requirements.
2. Superior Quality & Strict Testing: Every machine undergoes 72-hour continuous operation testing before delivery to ensure stable performance. Key components (blade, hydraulic pump, motor) are sourced from well-known brands, with a 2-year warranty for core parts. We strictly follow ISO 9001 quality standards to ensure each product meets industry requirements.
3. Cost-Effective & Efficient Solution: Compared with fully automatic models, our semi-automatic machine has a lower cost and is more suitable for small and medium-sized enterprises. The 0-15m/min adjustable speed and high peeling efficiency reduce processing time by 30% and labor costs by 40% compared to traditional manual or semi-manual methods. The durable blade and low failure rate reduce long-term maintenance costs by 40% over 5 years.
4. Global After-Sales Support: We provide 24/7 technical support via email, WhatsApp, and video call.

A: Yes. The machine is equipped with a high-hardness alloy blade and adjustable peeling force, which can handle alloy steel bars with tensile strength ≤1100 MPa and surface hardness ≤HB320. For extra-hard alloys, we can customize the blade material and hydraulic system to ensure smooth peeling without blade damage.

A: The standard 9CrSi alloy steel blade can be used for 8-12 months under normal operation (8 hours/day). The service life varies according to the processed material—for mild carbon steel, it can last up to 12 months; for stainless steel and hard alloys, it is 6-8 months. We provide low-cost replacement blades and on-site sharpening services to minimize downtime.

A: Regular maintenance is simple: ① Replace hydraulic oil every 6 months (use 46# anti-wear oil); ② Clean the oil filter and guide rails monthly; ③ Check the blade tightness and replace worn blades in time; ④ Lubricate moving parts every week. We provide a detailed maintenance schedule, and our after-sales team can provide remote maintenance guidance if needed. We also offer free replacement seals for the first year.

A: Yes. The machine supports stepless speed regulation (0-15m/min), and the feeding speed can be adjusted at any time during operation without stopping the machine. This allows you to flexibly adapt to different material hardness and peeling requirements, ensuring both efficiency and precision. For example, you can use a higher speed for mild carbon steel and a lower speed for hard alloy steel.

A: The standard maximum bar length is 5500 mm, and we can customize it to process extra-long bars (≥4000 mm) according to your needs. The machine is equipped with a stable feeding rack and guide device to ensure smooth processing of extra-long bars without bending or deviation. It is especially suitable for processing extra-long bright bars.
