Combo inline wheels are multi-functional polishing wheels designed for inline stone polishing machines that run multiple heads simultaneously across a slab surface. The combo design integrates different abrasive characteristics in a single wheel, allowing each head to perform both grinding and polishing functions — reducing the number of head changes required during a polishing cycle. 

Used in high-volume stone fabrication shops where machine uptime and throughput per shift are the primary metrics. Combo wheels are particularly efficient on long production runs of the same material type where consistent results are required across multiple slabs without stopping to change heads.
