8 Sets of Inner Tube Polishing Machines Shipped to Build Automated Mirror Polishing Production Line

Recently, XINYIDA successfully completed the production and shipment of 8 sets of automatic inner tube polishing machines for a repeat customer. The machines will be integrated into a fully automated polishing line with a gantry robot loading and unloading system, achieving a final surface roughness of Ra 0.2 μm and a high-quality mirror finish.

Customer Reorder Demonstrates Confidence in Equipment Performance

After successfully operating our polishing machines in production, the customer expanded capacity and placed an additional order for 8 machines. The repeat order reflects the reliability, polishing quality, and production efficiency delivered by XINYIDA equipment.

Project Overview

Workpiece Specification

• Inner Diameter Range: Ø200–600 mm
• Effective Polishing Length: 1500 mm
• Material: Stainless Steel Tubes
• Surface Requirement: Mirror Finish

Production Line Configuration

• 8 Automatic Inner Tube Polishing Machines
• Gantry Robot Material Handling System
• Automatic Workpiece Transfer Between Stations
• Continuous Production Process

The automated line significantly reduces manual handling, improves consistency, and increases production efficiency.

Achieving Ra 0.2 μm Mirror Finish

The polishing process is precisely controlled through optimized polishing pressure, spindle speed, and feed movement. The finished surface reaches Ra 0.2 μm, providing a uniform mirror appearance and meeting demanding sanitary and industrial requirements.

Shipment Ready

All machines have completed factory testing and customer acceptance inspection. The equipment has been loaded and shipped today and will soon be installed at the customer's facility.

XINYIDA continues to provide customized polishing solutions for stainless steel tubes, tanks, vessels, dished heads, and other industrial components, helping manufacturers improve surface quality, productivity, and automation levels.
