Performance Factors

Surface Finish

You want your stainless steel coils to look smooth and shiny. The way the surface looks depends on things like the abrasive type, how fast you polish, and how much pressure you use. Using a double side polishing machine in stainless steel coil processing helps you get a finish that meets industry rules.

Industry standards say a mirror finish has a surface roughness (Ra) between 1 and 12 microinches (µin). Many high-tech companies want about 8 Ra µin. Some advanced polishing tools can reach 4 Ra µin, which is very good. You can pick different abrasive grits, from coarse (8-24 grit) to very fine (220-1200 grit), to get the finish you need. Finer grits help make the surface smoother and shinier.

Tip: Always check the starting sheet finish, like No.4 or 2B/BA, before you polish. This helps you pick the right abrasive and process.

The table below shows how polishing settings change important results:

Performance Metric	Typical Range / Value	Measurement Standard	Influencing Polishing Parameters
Surface Roughness (Ra)	0.05–0.2 μm	ISO 4287	Abrasive grit size, polishing duration, speed, pressure
Gloss Level	80–95 Gloss Units (GU)	ASTM D523	Polishing compound, speed, pressure control
Corrosion Resistance	Improved with coatings	ASTM B117 (salt spray)	Surface cleanliness, polishing quality, pressure control
Adhesion Strength	>10 MPa	ASTM D4541	Surface roughness, cleanliness, polishing parameters

If you polish stainless steel for medical or decorative uses, you need very low Ra values. This helps stop bacteria from sticking and makes the metal look better.

Speed Control

Speed control is very important for polishing. If the speed is too low, polishing takes longer and the finish may not be smooth. If the speed is too high, the surface can get too hot and damaged. New machines let you change the speed to fit the coil and the finish you want.

Tests show that raising the polishing speed from 500 rpm to 1000 rpm can make the surface three times smoother after 30 minutes. This means you get a better finish faster. The chart below shows how surface roughness goes down as speed goes up:

You also need to watch the pressure. Too much pressure can cause problems and lower corrosion resistance. The best machines use smart controls to keep speed and pressure steady, so you get the same finish every time.

Coil Compatibility

You need to match the machine’s specs to your coil’s thickness, width, and material grade. Not every machine can handle all coil sizes or weights. Some machines can work with coils up to 2500 mm in diameter and 2400 mm in width, and up to 40 metric tons. This means you can polish both small and big coils without trouble.

Here is a table showing how machine specs affect coil handling:

Machine Specification	Quantitative Data	Impact on Coil Handling and Material Compatibility
Strapping Force/Tension	Up to 20,000 Newtons	Handles thicker and wider coils by applying enough tension
Strapping Speed/Cycle Time	16 coils/hour to 52 cycles per minute	Higher speeds improve throughput for various coil sizes and materials
Applicable Band Width	19-32 mm	Matches coil width and band material grade
Coil Size Handling Capacity	Up to 2500 mm outer diameter, 2400 mm width	Supports large coil dimensions, affecting thickness and width handling
Coil Weight Capacity	Up to 40 metric tons	Packages heavy coils, important for material grade strength
Band Material Compatibility	Steel and PET bands	Steel offers strength; PET offers elasticity and corrosion resistance
Joint Strength (Welding Methods)	Friction welding up to 95% of band strength	Ensures secure strapping across different material grades
Automation Level	Manual to fully automatic lines	Automation improves consistency and efficiency for diverse coil specs

When you pick a double side polishing machine in stainless steel coil processing, always check if it fits your coil’s size and material. This helps you get smooth work and great results.

Automation and Usability

You need controls that are easy to use. Modern machines have touchscreens and simple dashboards. You can set polishing speed and pressure with a few taps. Easy controls help you find problems fast and fix them quickly. Many factories use HMIs and PLCs to watch the process in real time. You can change settings fast to keep things moving. Companies using these systems have less downtime and make more products. Automated picking systems can make cycles up to three times faster. Fewer mistakes happen because the system gives you step-by-step help.

Tip: Training your team on these controls helps them learn and fix problems faster.

Maintenance

Good maintenance keeps your machine working well. You should check your machine often and follow a schedule. This means looking for worn parts, cleaning, and using tools to find problems early. Many companies use CMMS to track repairs and plan service. Companies with strong maintenance have up to 45% less downtime and 30% lower costs. They also make 25% more products. You can track MTBF and MTTR to see how well your maintenance works.

· Preventive maintenance stops problems before they start.
