The CNC Series Bearing Type Spindle Centerless Grinders offer high rigidity and precision with multi-axis CNC control, driven by servo motors for convenience and accurate positioning. The use of high-accuracy NN bearings in the grinding wheel spindle ensures both precision and rigidity.
Compared to the FCL series, this Centerless Grinding Machine achieves a significant 26% energy saving, reducing production costs and environmental impact. CNC technology allows flexible and efficient operation, making it suitable for various industries like machining, mold manufacturing, and automotive, providing high-quality processing solutions.
Palmary's CNC Series Bearing Type Spindle Centerless Grinder combines CNC technology and Centerless Grinding Machines, delivering high performance, accuracy, and energy efficiency for an excellent processing experience.
High accuacry
High grinding accuracy and rigidity design for max. 6 axes CNC control bearing spindle type grinder for wide range application.
High stability
The best configuration for machine bed and structural support ribs make the grinding accuracies more stability and reach higher accuracy level.
Bearing spindle type
The machine has the grinding wheel spindle single bearing holding type equipped with super precision cylindrical roller bearings make centerless grinding easier and more accurate than ever before.
Automation
For different auto application, the high speed loading & unloading attachment is optional to equop.
