These are horizontal lathes with integrated automatic handling outside the machine‘s workspace. The handling device is adapted to the workpiece and the required capacity. Replacement is fully automated by the machine when it is called up at the end of the NC program and the NC program is automatically started after successful workpiece replacement. Workpiece replacement ranges from 7 to 14 seconds depending on the size of the parts and is carried out using pneumatic cylinders and electric motors. This concept of handling is very widespread for its serviceability and reliability. The handling device is manually movable for easy removal away from the work area. This ensures easy access to the workspace of the tool changer and possible service interventions. Machines combine simplicity of design and high performance.
In addition, the SP 28 B horizontal lathe is complemented by a controlled B axis located at the bottom of the cast iron bed for the use of hydraulic double lunette for turning long workpieces. This solution allows you to independently program the lunette position and advance speed in the Z-axis during machining and fast advance to move to the starting position when the workpiece is changed. This solution significantly increases machine utilization and shortens downtime.
