The SDYQ is the main model of BLC cutting machine, offering cutting widths from 3.0 to 10.0 meters. Floor mounted T-ralils provide longitudinal travel in increments of 2.0 meters. Heavy walled box beam construction on the main beam is mated to an all welded, stress relieved trucks via machined mating surfaces. These features include dual linear rails and bearings on the cross beam, linear motion actuator vertical torch lifters, AC brush less drive motors and backlash adjustable gearbox. Combine this with the power and flexibility of BLC GNC550, steady and height precision cutting process can be achieved.
