Advantages

Why I/O Segmented

Dual-surface grinding delivers compounding efficiency gains across your entire double edger line.

Doubles Throughput

Both edges ground simultaneously — 100% throughput increase vs single-surface wheels. The fastest way to process both edges in a single pass.

Dual-Grit Capability

ID and OD segments can have different grit sizes. Achieve different finish grades on each edge without changing wheels or running the glass twice.

Reduced Footprint

One dual-surface wheel replaces two single-surface wheels. Smaller machine footprint and fewer spindles needed for the same output.

Balanced Wear

Patented bonding process ensures ID and OD segments wear at the same rate. Consistent edge quality from first meter to last.

100% Throughput Increase

By grinding both edges simultaneously in a single pass, I/O segmented wheels effectively double the grinding throughput of any double edger line — the fastest path to higher output without additional machine investment.

Where It Matters

Built for high-throughput lines where both edges need grinding at production speed.

Double Edger Lines

High-Volume Production

Double edger lines are the primary application for I/O segmented wheels. As glass sheets pass through the machine, both edges are ground simultaneously by the dual-surface wheel — one set of wheels replaces two. This eliminates the need for separate single-surface wheels on each side, reduces machine footprint, and dramatically increases throughput for straight-line edging operations.

Maintenance

Keep Them Balanced

Five essential practices to maximize dual-surface wheel life and maintain consistent edge quality on both ID and OD.

01

Verify Machine Compatibility

I/O wheels require specific double-edger machines. Verify your machine model supports I/O wheels before ordering. Not all double edgers are compatible.

More
02

Monitor Both Surfaces

Check both ID and OD segment wear independently. Uneven wear between surfaces indicates alignment issues or coolant imbalance.

More
03

Dress Both Surfaces

When dressing, address both ID and OD simultaneously. Dressing only one surface creates an imbalance that affects edge quality.

More
04

Replace as a Set

Always replace both I/O wheels as a pair. Mixing old and new wheels creates uneven grinding and inconsistent edge quality.

More
05

Track Combined Throughput

Log total linear meters (both edges combined) per wheel set. This gives true cost-per-meter for accurate budgeting.

FAQ

Common Questions

Everything you need to know about inner/outer segmented diamond wheels.

I/O wheels require horizontal double edger lines with dual-surface spindle capability. Not all double edgers support I/O wheels — check your machine specifications. Compatible machines are listed in our compatibility matrix.

Yes. This is one of the key advantages. Common setup: coarser grit on OD (primary grinding) and finer grit on ID (finer finish). This optimizes both edges in a single pass.

Slightly shorter — typically 700–1,000 linear meters vs 800–1,200 for single-surface segmented. However, the doubled throughput means lower cost-per-meter despite the shorter wheel life.

Uneven wear indicates alignment issues or coolant imbalance. Correct the root cause immediately — continuing with uneven wear damages both the wheel and the glass. Contact Hanwin support for alignment guidance.
