Jingkun 300 Edge Grinding Machine
Product Positioning
The Jingkun 300 is a compact planetary disc grinder developed in response to market needs. It is specifically designed for fine grinding in small‑to‑medium‑sized areas such as residential floors, hospitals, small rooms, schools, and stone surfaces. Lightweight and easy to maneuver, it is available in both 380V and 220V versions to suit various job site conditions.
Core Advantages
1. Edge‑to‑Edge Grinding, No More Secondary Touch‑Ups
Traditional grinders cannot reach walls or corners, requiring manual secondary edge finishing – which is time‑consuming and labor‑intensive. The Jingkun 300 delivers true edge‑to‑edge grinding, eliminating the need for any secondary handwork, significantly saving both time and labor costs.
2. Planetary 360° No‑Dead‑Angle Grinding
With a planetary structure where a large plate drives multiple small plates, the machine rotates 360° for grinding. This ensures a flatter surface with no gaps or missed spots, and leaves finer, more uniform scratch patterns.
3. Multi‑Purpose with Flexible Compatibility
The 9‑head design allows the installation of various consumables such as diamond segments, grinding pads, and 3‑hole segments. One machine fulfills multiple tasks, reducing equipment procurement costs.
4. Powerful and Stable Performance
Equipped with a 7.5kW high‑power motor and an 11kW high‑power frequency converter, it delivers strong grinding force and excellent finishing results. The integrated die‑cast aluminum housing offers high density and superior heat dissipation. The high‑ratio helical gear transmission ensures smooth operation without tooth skipping or disc jamming, guaranteeing long‑term durability.
5. User‑Friendly Design for Easy Operation
· Articulated handle with three‑height adjustment to accommodate operators of different statures.
· Ergonomically designed 180° rotatable insulated handle – wear‑resistant, non‑slip, and shockproof.
· Large‑capacity 304 stainless steel water tank and stainless steel control panel – corrosion‑resistant, rust‑proof, attractive, and durable.
Applicable Scenarios
Fine grinding projects in small‑to‑medium areas, including residential floors, hospitals, schools, small rooms, and stone surfaces.
Tagline
Jingkun 300 – Compact yet Powerful. Edge‑to‑edge without dead corners, precision grinding every inch.
Having used various floor grinding machines on different projects, I can say the Jingkun 300 stands out for its truly edge-to-edge grinding capability. Unlike traditional grinders that leave corners unfinished and require extra hand polishing, this machine's planetary 360° feature ensures no spots are missed, saving valuable time and effort. One aspect I appreciate is the 9-head design, which allows for flexible attachment of diamond segments, grinding pads, or three-hole segments. This versatility means fewer tools need to be purchased or rented for different surface types, streamlining the workflow and reducing costs. The machine’s ergonomic features also make a noticeable difference. The adjustable articulated handle caters to different operator heights, reducing fatigue during long periods of use. The insulated, rotatable handle improves grip and control while minimizing vibrations, which adds comfort and safety. On a recent job smoothing a hospital floor, the Jingkun 300’s powerful 7.5kW motor coupled with the high-quality frequency converter delivered consistent, powerful grinding without stalling, even on tougher stone surfaces. The die-cast aluminum housing helped keep the motor cool, preventing overheating during extended runs. For anyone working on detailed floor finishing in constrained or sensitive environments like schools or residential buildings, this grinder’s compact size and maneuverability make it an excellent choice. Its rust-proof stainless steel water tank and control panel held up well against corrosion during wet grinding applications. In summary, the Jingkun 300 offers significant efficiency gains and operational ease for fine surface grinding projects. It combines power, precision, and user-friendly features that help professional contractors and DIY enthusiasts alike achieve flawless floor finishes without extra manual touch-ups.
