The HLS Series Granite Edge Polisher Machine is designed for automated grinding, profiling, chamfering and polishing of granite slab edges. It combines multiple processing heads in a continuous-feed configuration, helping stone fabricators produce consistent edge profiles and surface finishes with less manual polishing.

From Raw Edge to Finished Profile
The machine processes the stone edge through a controlled sequence rather than relying on a single polishing operation.
Edge Feeding
The slab is positioned and continuously fed into the processing area. The conveying system maintains stable movement during edge processing.
Profile Grinding
The first processing heads remove excess material and establish the required edge geometry.
Fine Grinding
Subsequent abrasive stages refine the shaped edge and reduce grinding marks.
Edge Polishing
Polishing heads progressively improve the edge surface and gloss.
Finished Edge
The finished edge is ready for subsequent fabrication, assembly or installation according to the customer's production process.
Why Automate Granite Edge Polishing?
For low-volume custom work, manual edge polishing may suffice. As production scales up, however, maintaining consistent edge geometry and gloss across batches becomes increasingly difficult. The HLS Series is built for manufacturers who need repeatable edge processing at higher volumes.
Consistent Edge Geometry – Multi-stage processing maintains a repeatable profile, reducing reliance on operator skill.
Uniform Gloss – Sequential grinding and polishing minimize brightness variation between workpieces.
Reduced Skilled Labor Dependency – Automated processing cuts post-machining manual grinding and polishing.
Batch-to-Batch Consistency – Once parameters are set, the same configuration applies to similar materials and profiles.
Easier Production Planning – Continuous feeding integrates edge processing into regular workflow, not as an occasional manual task.

FAQ
Q: Can the machine polish both granite and marble?
A: Yes. The machine can be configured for granite, marble, quartz and other compatible stone materials. Abrasive selection and processing parameters may differ between materials.
Q: Can I request a specific edge profile?
A: Yes. When requesting a quotation, it is recommended to send an edge-profile drawing or a clear dimensional sketch. This allows the machine and tooling configuration to be evaluated more accurately.
Q: How do I reduce edge chipping during processing?
A: Edge chipping can be affected by material characteristics, tool condition, grinding sequence, feed speed, and processing pressure. Proper tooling and process parameters should be selected according to the stone being processed. We can recommend suitable configurations based on your material.
Q: How long is the delivery cycle?
A: The production cycle depends on the equipment configuration and order scheduling. Standard products can be provided within 15-30 days. Configured products will require an additional time period. Please confirm the delivery date with us when placing the order.
Q: What payment terms are available?
A: We support common trade terms such as FOB, EXW, and CIF. The specific payment schedule should be confirmed in the quotation and proforma invoice.
