LSD-162
The LSD-162 Manual Grinder, also known as the SwingGrinder M, is a smart, semi-automatic solution for deburring and edge rounding of laser-cut, plasma-cut, or punched metal parts. Designed to fill the gap between fully manual power tool grinding and expensive through-feed machines, this compact grinder provides three to four times the speed of manual deburring, while maintaining precision, control, and affordability.
The LSD-162 features a swinging arm with a counterbalanced grinding head. Two rotating disc tools are mounted on this arm, which can be guided manually over the workpiece. The operator applies pressure from above, allowing for full edge access and multi-angle coverage. The head can be tilted 180°, enabling quick switching between a deburring disc and an edge rounding disc, significantly boosting productivity.
✅ Semi-automatic manual operation — faster than hand tools, more affordable than through-feed machines
✅ Swinging arm with weight compensation — fatigue-free, smooth handling
✅ Rotating head — allows fast disc tool change (e.g., from deburring to edge rounding)
✅ High-friction worktable surface — keeps parts stable during grinding
✅ Vacuum hold-down option — for lightweight or smaller parts
✅ Dust drawer + extraction outlet — improves air quality and cleanliness
✅ Automatic motor shut-off — for safety when the head is tilted
✅ Pneumatic arm brakes — prevent uncontrolled swinging
✅ Magnet system option ("M" model) — for securing ferritic/mild steel under the table mat
Tool Name | Application |
---|---|
SoftDisc | Soft pad for deburring mild steel or aluminum |
CompactDisc | For removing heavy burrs and spatter on stainless steel |
MediumDisc | For effective edge rounding (various grit/hardness available) |
OrbitalDisc | Creates a non-directional finish (patent pending Orbital device) |
SmartFlexDisc | Edge rounding on foil-coated, zinc-coated, or slightly warped parts |
OxideDisc | Removes oxide layer on cut edges |
HammerDisc | For knocking off heavy slag before fine grinding |
Laser-cut and plasma-cut parts
Punched metal components
Mild steel, stainless steel, and aluminum
Foil-laminated or zinc-coated parts
Deslagging, deburring, edge rounding, oxide removal

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.

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.
