STP80 Pipe Polishing Machine – 2-100mm Working Diameter, 0.02mm Accuracy, Adjustable 0-10m/min Speed

STP80 Pipe Polishing Machine Delivers High-Precision Surface Finishing for Pipes 2–100mm In the competitive world of metal fabrication, surface quality is no longer a luxury—it is a decisive factor in winning orders and commanding premium prices. Today we are pleased to introduce the STP80 pipe polishing machine, a robust and highly accurate solution engineered for polishing and grinding round pipes and tubes with diameters ranging from 2mm to 100mm. The STP80 is designed for manufacturers of stainless steel pipes, sanitary tubes, handrails, furniture tubing and industrial piping who demand consistent, mirror-like finishes at production speed. With a polishing accuracy of 0.02mm, the machine delivers repeatable, uniform results that meet the most stringent quality standards.

• Wide working range: Handles pipes with a maximum working diameter of 2–100mm, covering a broad spectrum of tube sizes.
• High polishing accuracy: 0.02mm accuracy ensures a uniform, high-quality surface finish on every workpiece.
• Adjustable working speed: 0–10 m/min, fully adjustable to match different material types and finish requirements.
• Powerful 4kW main motor: Delivers stable, efficient grinding and polishing performance at 1400rpm.
• Dual-wheel configuration: Comes complete with 2 polishing wheels and 2 grinding wheels for flexible rough grinding and fine polishing in one pass.
• Sturdy guide roller system: 230mm guide rollers and a dedicated 0.4kW guide roller motor ensure smooth, precise tube feeding.
• Industrial 415V 3-phase power: Built for continuous production environments.

• Stainless steel pipe and tube surface polishing
• Sanitary and food-grade tube finishing
• Handrail, railing and architectural tubing
• Furniture and automotive tubular components
• Industrial piping before coating or delivery

Combining precision, power and flexibility, the STP80 helps manufacturers reduce manual finishing labor, improve consistency and shorten delivery times. The adjustable speed control allows operators to fine-tune the process for different materials—from soft aluminum tubes to hardened stainless steel—while the 0.02mm accuracy guarantees a flawless surface that impresses even the most demanding buyers.
