Pick-up Vertical Turning Machines with Transfer Technology

The Compact Production Turning Machine Unique machine design The proprietary Hessapp DVT design stands for complete large doors and windows guarantees maximum user friendli- machining without compromise, combined with maximum ness, easy setup and fixturing. As the turnover station is precision. When it comes to high precision in one chucking dispensed with, automation setup times are also minimized. after another, in particular, the advantages are significant, because the workpiece is transferred to the next chuck still clamped, without losing its position. Ever more restricted 3 General...

Complete Machining of Two Workpieces without Turnover Device The uniqueness of the DVT Instead of two individual machines linked by handling and turnover stations, just one DVT is required for machining workpieces from two sides with maximum precision. The basis for this system is the automatic loading of the machine through the suspended spindle and machining in an enclosed work area. Direct transfer to the chuck of the fixed spindle after machining takes place without any loss of quality between the two chucking operations. Step 1: Load Step 2: Machine 1st side Step 3: Transfer workpiece...
