At the heart of every engine is a finely tuned crankshaft. This part transforms the piston movement (via the connecting rods) from linear to rotational. And this movement is what powers diesel marine engines, locomotive internal combustion engines, large compressors, and other heavy-duty machinery.
CNC Crankshaft grinding machines are used for grinding journals and crank pins to remove material and refurbish the expensive yet vital part of an engine. Crankshaft grinding is usually done when rebuilding an engine, and it also provides performance enhancements.
In addition to our standard Ecotech Machinery crankshaft grinders, we also offer the line of Robbi crankshaft grinding machines, including their industrial application line. Designed for the most accurate and efficient operation, Robbi's machines use work heads with 4-way cross slides and an advanced locking system (allowing quick crankshaft centering).
This heavy-duty one-piece cast iron construction delivers a lifetime of superior accuracy and dependability. With a variety of machine variations, Robbi has differently configured options to provide the tool you need for your specific application.
Our crankshaft grinders are suitable for single-piece runs and for production lots.
