A grinding travel of 600 mm on the longitudinal axis and a cross travel of 300 mm make this machine ideal for toolmaking, jig and fixture construction, and small batch production. This model series is characterized by extensive standard equipment and ease of use. The robust spindle head design and the double V guideways in both the longitudinal and cross axes guarantee long-term precision. The intuitive controls make operation easy and significantly increase productivity. The guideways are regularly lubricated via central lubrication. The Jung has been mechanically and electrically checked by us. Take advantage of the opportunity to view and test the Jung on site under power. Further surface grinders from well-known manufacturers can be found on our website.
