The SDVEDON MQ8260A is a high-precision crankshaft grinding machine designed for efficient grinding of engine crankshaft pins, journals and crankpins. Built on a heavy-duty cast iron bed with combined mechanical, electric and hydraulic control, it delivers stable performance, reliable safety and easy operation.

With a maximum swing of Φ580mm and a maximum grinding length of 2000mm, it supports workpieces from 30mm to 200mm in diameter, making it suitable for various engine crankshafts. The headstock offers adjustable speeds for both 50Hz and 60Hz power supplies, while the 760rpm wheelhead ensures high-efficiency grinding. The machine achieves excellent precision with roundness of 0.005mm, diameter uniformity of 0.008mm and surface roughness Ra 0.32μm, meeting strict quality requirements for crankshafts.

Equipped with a complete hydraulic system and coolant system, it ensures stable feed and effective cooling during grinding. Safety interlock mechanisms prevent misoperation, enhancing user safety. Widely used in engine manufacturing and auto parts industries, the SDVEDON MQ8260A is backed by CE/ISO 9001 certification and a 1-year full warranty.

The machine bed and key components are made of high-strength cast iron, with reasonable rib layout and heat treatment to eliminate residual stress. This ensures excellent rigidity, vibration absorption and long-term stability, even under heavy-load grinding conditions.

• Headstock: Three adjustable speeds for 50Hz/60Hz power, driven by a 1.5kW motor for stable workpiece rotation.
• Wheelhead: Equipped with a 7.5kW motor, the grinding wheel runs at 760rpm, with a maximum wheel size of 900×40×305mm for strong cutting power.
• Table System: The upper table can swing ±1°30′, and the longitudinal travel reaches 2000mm, supporting long workpieces.

• Hydraulic System: With 1–1.3MPa working pressure, it provides stable and adjustable feed movement, improving grinding efficiency.
• Coolant System: 50L/min coolant pump ensures sufficient cooling and chip removal, extending wheel life and improving surface quality.
• Safety Interlock: The worktable and wheelhead are designed with hydraulic and electric interlocking to prevent accidents caused by misoperation.

The machine has passed CE and ISO 9001 international quality system certification, complying with JB/T2617.2-1999 manufacturing standards. All core components are selected from reliable brands. Before delivery, each machine undergoes strict precision inspection and performance testing, ensuring stable and reliable operation. As a professional crankshaft grinding solution from SDVEDON, the MQ8260A 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 coolant 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 engine manufacturing, auto parts processing, and mechanical maintenance industries. It is especially suitable for grinding engine crankshaft pins, journals and crankpins, and is an ideal equipment for auto repair workshops, engine factories, and processing enterprises for crankshaft precision grinding.
