LSD-162

The LSD-162 Manual Deburring Machine is a versatile combination of a robust workbench and a mechanical polishing arm designed specifically for small-batch metal plate surface polishing, slag removal, deburring, and other finishing processes. This machine offers an efficient and user-friendly manual operation, enabling operators to control grinding strength simply by applying gentle pressure.
Workbench with Automatic Vacuum Adsorption Table: The machine features an automatic vacuum system that evenly distributes suction force across the work surface. This allows workpieces to be securely held flat without the need for mechanical clamps, significantly improving operational efficiency and safety.
Manual Control with Mechanical Polishing Arm: The mechanical polishing arm facilitates precise manual grinding. Operators can select from various disc brushes tailored to the workpiece material and finish requirements, ensuring optimal results.
Dual Grinding Heads with Quick-Swap Design: The machine is equipped with two grinding heads powered by a single motor. By rotating the arm 180 degrees, users can quickly switch between grinding heads, minimizing downtime and maximizing productivity.
Integrated Dust Extraction System: An automatic vacuum extraction system removes dust generated during grinding, protecting worker health and maintaining a clean workshop environment.
| Parameter | Specification |
|---|---|
| Work Platform Size | 1200 mm × 750 mm |
| Gross Power | 3.86 kW |
| Machining Thickness | 0.5 – 200 mm |
| Brush Diameter | Ø 162 mm |
| Maximum Speed | [Not specified, assumed standard for model] |
| Suction Air Volume | 1000 m³/h |
| Maximum Chip Size | Ø 150 mm |
On-Site Acceptance Testing: The machine acceptance will be conducted on-site by the supplier (Party B) with prior notification to the purchaser (Party A) one week in advance. Party A may provide qualified test components for evaluation; these will be returned post-testing. Acceptance via video inspection is also permitted.
Standards Compliance: Acceptance will be based on the technical agreement, signed documentation, applicable national standards, and comprehensive testing covering mechanical, electrical, and safety functions.
Issue Resolution: Any issues found during acceptance will be addressed by Party B according to agreed-upon resolutions documented in the acceptance minutes. Changes to these requirements must be mutually agreed upon in writing. Only after full qualification will the machine be delivered to Party A.
