Product Overview
The SDVEDON MA8280B/H is a heavy-duty crankshaft grinding machine specifically engineered for grinding main journals and crankpin outer diameters of large crankshafts used in marine diesel engines, locomotive internal combustion engines, large compressors, and other heavy power machinery. With a maximum swing diameter of Φ800mm over the table and a grinding length of 3000mm, this machine is capable of handling medium to large engine crankshafts with exceptional precision.
Key Features
Robust & Stable Machine Bed - Cast from low-alloy, high-hardness, low-stress inoculated cast iron with flat-V guideways and telescopic stainless steel protective covers.
High-Precision Hydrostatic Spindle System - Headstock and tailstock spindles supported by hydrostatic bearings with Mitsubishi servo motor system for stepless speed control.
Precision Worktable & Guideways - Longitudinal movement with manual or hydraulic operation, flat-V sliding guideways lined with plastic for low friction and wear resistance.
Efficient Grinding Wheel Head - Hydraulic rapid advance and retract functions with precise manual feed control down to 0.005mm increments.
Comprehensive Steady Rest & Clamping System - Two-point steady rests with adjustable clamping range and manual high-precision indexing chucks.

Applications
Primarily used for grinding main journals and crankpin outer diameters of crankshafts for marine diesel engines, locomotive internal combustion engines, large compressors, large power machinery, and medium-sized engine crankshafts. Suitable for machining carbon steel, alloy steel, cast iron, and other materials. Ideal for heavy equipment manufacturing plants, diesel engine repair centers, locomotive overhaul workshops, and large machinery rebuilding facilities.
Safety & Operation Notices
- Read the operation manual thoroughly before installation and operation
- Ensure the foundation is prepared according to the foundation drawing before machine installation
- Always wear safety goggles and hearing protection when operating
- Check the hydrostatic bearing oil pressure before starting the spindle; do not start without proper pressure
- Keep the magnetic separator and coolant system clean to ensure effective chip removal
- When changing grinding wheels, always use the supplied lifting bar and static balancer
- Do not exceed the maximum workpiece weight or swing diameter limits
- Regularly inspect and lubricate all guideways according to the lubrication chart
- Disconnect power before cleaning or performing maintenance
- For eccentric grinding of crankpins, ensure the counterweights are properly adjusted to avoid imbalance
