In every high-functioning engine is a finely crafted crankshaft. Through the connecting rods, the crankshaft transfers power from the piston movement from linear to rotational. This harnessed power is used by most conventional cars, diesel marine engines, locomotive internal combustion engines, large compressors, and other heavy-duty machinery.

Our crankshaft grinders are suitable for single-piece runs and for production lots.

Robbi Crankshaft Grinders

Robbi offers a line of crankshaft grinders that includes their heavy-duty industrial line. These machines are designed for high accuracy and efficient operations using workheads with 4-way cross-slides and an advanced locking system for quick crankshaft centering.

With lifetime superior accuracy and dependability, these one-piece cast iron constructed machines also deliver various configurable options to make the machine tool work best for how you need it.

• Wheel Head: The wheel head is coated with anti-friction material and bathed in adjustable bearings to allow free movement and minimize wear on the machine
• Hydraulic Controls:  Increase setup and grinding speed with the rapid hydraulic wheel head and table.
• Work Heads: With only two keys for all shifting, centering, and clamping operations indexed chucks easily change from chucks to centers and rotate 360 degrees.

Ecotech Machine Tool offers four convention crankshaft grinding machines. 

We also offer four industrial line machines, with an option for CNC in the Rex 400 machine model.
