An oxide removal machine removes the dark oxide layer and thermal cutting residue from laser cut sheet metal edges using abrasive belts and flexible grinding rollers. It is especially useful after oxygen cutting of carbon steel, because oxide left on the edge weakens coating adhesion, complicates welding and spoils final appearance. The HORISTAR HM series combines burr removal, oxide cleaning and edge rounding (R0.1–0.5 mm) in a single automated process.

Product Positioning
Many buyers search for a “deburring machine” when their real problem is the oxide layer. Burr removal, edge rounding and oxide removal are related but not the same process. This machine fits if your factory has one or more of these problems:
How the Machine Works
The HM series uses a dual sanding system with multiple flexible grinding rollers (6 on the HM-1000G-W, 8 on the HM-1300G-W) running over a feed conveyor. As parts pass under the abrasive belt and rollers, the system removes burrs, cleans the oxide layer and rounds sharp edges to a controllable R0.1–0.5 mm radius. Feed speed is adjustable from 0.5 to 6 m/min to match material, thickness and finish requirement.
Vacuum Adsorption Workbench
A vacuum table firmly holds small or thin workpieces (down to 50 × 50 mm) so they finish without flipping or shifting, keeping dimensional accuracy and surface uniformity across every part.
PLC Touch-Screen Control
Belt speed, pressure and processing thickness are set on a digital PLC panel, with real-time monitoring and quick changeover between jobs. Operators can save and recall settings for repeatable production.
Reinforced Machine Body
The machine body is thickened and precision-milled to resist deformation under continuous heavy-duty operation. This keeps vibration low and maintains consistent abrasive contact across long production runs.
Automatic Belt Deviation Correction
A rubber drive roller with an eccentric-shaft design keeps the sanding belt aligned automatically, extending belt life and removing manual adjustment — reducing both downtime and consumable cost.
Intelligent Safety System
On an alarm or power failure the sanding belt halts automatically, and limit switches protect all motion positions. The system meets standard industrial safety requirements for continuous factory operation.
Oxide Removal vs Deburring vs Edge Rounding vs Surface Sanding
Remove the Dark Layer
Removes the dark oxide layer from thermally cut edges. Solves poor coating adhesion and welding preparation issues caused by oxygen laser and plasma cutting residue on carbon steel.
Remove Raised Burrs
Removes raised burrs and sharp residual material left on cut edges. Solves safety risk during handling, assembly interference and inconsistent quality from cutting parameter variation.
Create a Controlled Radius
Creates a small radius (R0.1–0.5 mm) on sharp edges. Improves powder coating coverage, eliminates handling injuries and meets assembly specification requirements for finished parts.
Improve Visible Texture
Improves the visible surface texture of flat faces and panels. Solves appearance requirements for stainless steel panels, architectural components and visible assemblies before finishing.
Some parts need only light deburring; others need oxide removal plus edge rounding before powder coating. The HM series can do all three in one pass, but the right belt and pressure settings depend on the part — HORISTAR recommends free sample testing before final machine selection.
Suitable Materials
The machine is used mainly for sheet metal parts. Final result depends on material, cutting method, burr condition, thickness, abrasive selection and machine settings.
Process Diagnosis: Identify the Real Edge Problem First
The correct configuration depends on the edge defect, so classify the defect on real parts rather than relying on the machine name.
Oxide removal is not a universal replacement for every finishing process — it is one part of a sheet metal finishing strategy.
Configuration Logic
HORISTAR matches the configuration to the edge condition and downstream process.
| Buyer Requirement | Recommended Direction |
|---|---|
| Remove oxide before welding | Abrasive belt — controlled edge cleaning |
| Prepare carbon steel for powder coating | Oxide removal + R0.1–0.5 mm edge rounding |
| Remove laser burrs and oxide together | Abrasive belt + flexible grinding rollers |
| Process small parts (down to 50 × 50 mm) | Vacuum adsorption workbench |
| Improve visible stainless panels | Surface sanding + edge finishing (tested first) |
| High daily output | HM-1300G-W — 1300 mm width, 8 rollers |
| Mixed thickness production | Adjustable pressure, speed + abrasive selection |
Carbon steel cut with oxygen usually needs oxide removal; nitrogen-cut parts have different edge conditions and may not.
Quality Criteria After Oxide Removal
Define the expected result before ordering. “Clean edge” is too vague — use practical inspection criteria.
| Inspection Item | Acceptable Result to Define |
|---|---|
| Oxide layer | Removed from the target edge area per your sample |
| Burr height | No sharp raised burr affecting handling or assembly |
| Edge radius | R0.1–0.5 mm or another agreed value if rounding is required |
| Coating preparation | Edge suitable for your coating process |
| Surface appearance | No unacceptable scratches on visible areas |
| Small part stability | Parts do not flip or shift during feeding |
| Consistency | Several parts show the same edge result |
If you have a coating specification, share it before machine recommendation. Coating failure often traces back to poor edge preparation, but the finishing machine must be matched to the paint or powder process.
Sample Testing Protocol
