RailGrind is a precision grinding machine for the production of compact linear guides. In the two-support version, the two profile sides of the linear guide rails are ground simultaneously. The three-support version has two grinding supports with vertical grinding spindles on the machine gantry for simultaneous grinding of the two profile side surfaces of the linear guide rail and one grinding support with horizontal grinding spindle for grinding the "contact surface" of the linear guide rail. The simultaneous machining of all three accuracy-determining surfaces of the workpiece achieves the highest accuracies. Translated with DeepL
