JL-2550CNC

Joen-Lih Hi-Precision NC surface grinders are designed to meet current and future grinding requirements.

The machines are engineered and manufactured to the highest industry standards – starting from the raw castings right through to quality testing. This ensures optimal surface grinding accuracy and finish. The goal is to exceed customers’ expectations for quality and investment.

The Y and Z axes are available to equip with linear scales (Optional equipment) that greatly upgrade positioning accuracy, machining accuracy and efficiency.

Wheel dressing parameters are controlled by programs. It provides a selection of automatic and semi-automatic operation modes, combined with automatic compensation functions, allowing the grinding wheel to be kept at an optimal condition at all times.
