The SDVEDON M1420/500 is a high-precision universal cylindrical grinding machine, designed for both external and internal grinding of cylindrical and conical surfaces, as well as axial end faces. Built on a rigid cast iron bed, it features hydraulic and manual combined feed control, ensuring stable operation and easy adjustment.

With a center height of 125mm and a maximum grinding length of 500mm, it supports external workpieces from Φ6 to Φ200mm and internal bores from Φ6 to Φ80mm. The headstock offers six adjustable speeds, while the wheelhead with a 4kW motor runs at a linear speed of 35m/s for efficient material removal. The machine achieves excellent precision with roundness up to 0.002mm, cylindricity 0.003mm and surface roughness Ra ≤ 0.32μm.

Equipped with a 25L/min coolant pump and 16L/min oil pump, it ensures effective cooling and lubrication during long grinding operations. The worktable can swivel from -5° to +9°, making it suitable for grinding tapered workpieces. Widely used in tool rooms, job shops and batch production lines, the SDVEDON M1420 is backed by CE/ISO 9001 certification and reliable after-sales service.

The machine bed, worktable and headstock are made of high-quality cast iron with stress-relief treatment, ensuring excellent rigidity and vibration absorption. The precision ground guideways are designed for smooth movement and long service life, providing a stable base for high-precision grinding.

• External & Internal Grinding: Equipped with an internal grinding spindle (21000r/min) for bores up to Φ80mm, making it a true universal grinder.
• Adjustable Worktable: The upper table swivels ±5°~+9°, allowing taper grinding for various workpieces.
• Wheelhead Control: The wheelhead with fine feed adjustment (0.00125mm per division) ensures precise infeed for fine finishing.

• Hydraulic Feed: The worktable is driven hydraulically with adjustable speed from 0.1–4mm/min, ensuring stable reciprocating motion.
• Cooling System: 25L/min coolant pump provides sufficient cooling for the grinding area, improving surface finish and wheel life.
• Lubrication System: 16L/min oil pump ensures smooth lubrication of guideways and moving parts, reducing wear.

The machine has passed CE and ISO 9001 international quality system certification, complying with relevant safety and quality standards. All core components are from reliable brands. Before delivery, each machine undergoes strict precision inspection and performance testing, ensuring stable and reliable operation. As a professional grinding solution from SDVEDON, the M1420 provides comprehensive after-sales service including on-site installation, debugging, technical training, and lifelong maintenance.

1. The machine must be installed by professional technicians in a flat, vibration-free workshop, ensuring sufficient power supply, hydraulic system, and cooling system are available on site.
2. Before operation, strictly follow the operation manual to inspect the spindle, grinding wheel, feed system, and other core components to guarantee normal operation.
3. Operators must receive professional training, wear necessary protective equipment, and strictly abide by safety operation rules to avoid personal injury.
4. Regular maintenance is essential: clean the machine periodically, calibrate the accuracy, check the grinding wheel balance, and inspect the hydraulic system to ensure long-term stable performance.
5. When performing maintenance, wheel change, or troubleshooting, please cut off the power supply first to avoid safety accidents.

Widely used in tool manufacturing, precision machinery, automotive, and general engineering industries. The SDVEDON M1420/500 is ideal for grinding cylindrical and tapered shafts, pins, sleeves, and internal bores, suitable for both batch production and tool room applications.
