Robbi Crankshaft Grinders

Robbi Crankshaft Grinders are engineered for precision grinding of journals and crank pins, essential for refurbishing critical engine components. This process is often necessary during engine rebuilds and enhances engine performance.

A finely crafted crankshaft is crucial for the efficient operation of any high-functioning engine. It converts the piston’s linear motion into rotational power via the connecting rods. This power is utilised in conventional cars, diesel marine engines, locomotive internal combustion engines, large compressors, and other heavy-duty machinery.

Robbi Crankshaft Grinders are ideal for both single-piece jobs and production runs.

Robbi offers an extensive range of crankshaft grinders, including a heavy-duty industrial line designed for high precision and efficient operation. These machines feature workheads with 4-way cross-slides and an advanced locking system for quick and accurate crankshaft centering. Built from one-piece cast iron, these grinders provide superior accuracy and reliability over their lifetime and offer various configurable options to meet specific needs.

Wheel Head: The wheel head is coated with anti-friction material and supported by adjustable bearings, allowing smooth movement and reducing wear on the machine.

Hydraulic Controls: Rapid hydraulic controls enhance setup and grinding speed with the wheel head and table.

Work Heads: Featuring indexed chucks that can easily switch between chucks and centres with just two keys, these work heads rotate 360 degrees, simplifying shifting, centering, and clamping operations.
