The SDVEDON MK1420 is a high-efficiency CNC external cylindrical grinding machine, developed for machining cylindrical, conical surfaces and cam parts. It features a robust HT300 cast iron bed with high rigidity, Huazhong open CNC system for flexible customization, and full servo drive control, enabling one-person multi-machine operation.

With a maximum grinding length of 500mm and external diameter up to Φ200mm, it supports internal grinding from Φ15-80mm. The machine achieves excellent precision: roundness 0.0015mm, cylindricity 0.003mm, and surface roughness Ra 0.4μm. Equipped with automatic wheel dressing and compensation, it ensures consistent quality in medium and large batch production.

The machine runs with Huazhong CNC system, featuring automatic grinding cycles, human-machine interface, and data acquisition functions. The full enclosure design protects internal components, while the cooling and lubrication systems ensure stable long-term operation. Widely used in automotive, motorcycle, and mechanical processing industries, the SDVEDON MK1420 is backed by CE/ISO certification and professional after-sales service.

The machine bed, carriage, pad and wheel frame are made of high-quality HT300 cast iron with one-piece casting and stress relief treatment. The heavy-duty roller linear guides ensure smooth motion and accurate micro-feed, providing a stable foundation for high-precision grinding.

• CNC System: Huazhong open CNC system with 2-axis servo control, supporting secondary development and automatic grinding cycles.
• Drive Components: Rexroth linear guides and high-precision ball screws eliminate backlash, ensuring stable feed and repeatability.
• Spindle System: 4kW external spindle (35m/s linear speed) and 1.1kW internal spindle (8000rpm) provide strong power for various grinding tasks.

The grinding wheel features automatic two-axis linkage dressing and automatic compensation after dressing. The diamond pen trimming method ensures consistent wheel profile and precision, reducing manual adjustment and improving efficiency.

• Cooling: 0.12kW coolant pump with 180L water tank, emulsion cooling with magnetic separator for effective heat and chip removal.
• Lubrication: Automatic circulation lubrication system for guide rails and ball screws, ensuring smooth movement and long service life.

The machine has passed CE and ISO 9001 international quality system certification, complying with safety and quality standards. All core components are from reliable brands. Before delivery, each machine undergoes strict precision inspection and performance testing. As a professional grinding solution from SDVEDON, the MK1420 provides comprehensive after-sales service including installation, debugging, 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 automotive, motorcycle, and mechanical processing industries. The SDVEDON MK1420 is especially suitable for medium and large batch production of cylindrical, conical and cam parts, ideal for precision grinding of shafts, pins, sleeves and other components.
