Emag offers its modular standard VL and VT product families. The vertical turning machines are designed to perform different operations on the same platform to increase efficiency while providing an affordable automation alternative, the company says.

The VL vertical pick-up lathe series is designed to efficiently machine a range of chucked components, small gearwheels, planetary gears, sun gears, sliding sleeves, synchronizer rings and flange components. The smallest lathe of the VL product line, the VL 2, machines workpieces with a maximum diameter of 4" and a length of approximately 6". Increasing in size, the VL 4, VL 6 and VL 8 offer different turning and milling operations within the framework of a single closed-loop production process. The VL8, the largest machine of the series, is specially designed for turning large components such as those for commercial vehicle production. The VL8 can turn workpieces as large as 16" in diameter and 12" long.

Built within the same concept is the VT series, which is designed to machine large quantities of shaft components. With four axes, a self­-loading turret and integrated automation, the VT 2-4 machines shafts with a maximum diameter of 2.5" and 16" in length. Spindle speeds ranging to 6,000 rpm reduce cycle times as the shaft is clamped vertically between the work spindle and tailstock and machined from two sides. The vertical alignment of the workpiece enables unhindered chip flow to prevent the buildup of nests in the machining area.

All machines of the VL and VT product families feature a pick-up spindle/turret, which loads the machine, picks up the raw parts from the integrated conveyor and returns the finished component.  A 12-station turret with short indexing times can be equipped with driven tools for drilling and milling operations.

Also on display is the VLC 200 H hobbing machine, which integrates Emag-Koepfer technology into the Emag vertical platform. It includes a pick-up design in which the main spindle removes the raw part from the conveyor belt, transfers it to the tailstock flange and removes it from the machining area after the hobbing cycle is complete. Gears with a maximum diameter of 8" and module 4 can be dry-milled at shortened cycle times.

    CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.
