JOKER 7000 CNC Controlled turning and milling Machine
   
The WEMA JOKER 7000 CNC is a further development of our tried-and-tested copying lathe WEMA JOKER 7000. The turning support and the longitudinal slide which run on hardened and ground low-maintenance ball transfer guides are features which are particularly worth mentioning. The lathe chisel is located very close to the revolving collar plate which guarantees vibration-free turning of the workpiece profile. Collar plates and accessory parts can be retrofitted at any time.
The standard design of the machine is equipped with 3 programmable axes: two feed axes and one rotational axis for milling.
   
All profiles can be designed using MEGA CAD on any external PC and transferred to the machine via interfaces. The machine can work unhindered during programming periods. A large memory area (32MB) allows storage of approximately 2000 programs. One PC is sufficient for several machines.
The drive unit for the supports is fitted to the rear of the machine to provide plenty of space on the operating side. The operating and control elements are both coordinated on a travelling control panel which can be adjusted in any position. All wires and ducts are collected in energy guide chains to prevent disturbances. All control and electronic components are located on the machine tool table. A separate electrical-control cabinet is therefore not required. The infinitely variable drives allow quick adjustment to optimum cutting conditions, thereby guaranteeing optimum turning and milling quality. The machine can be quickly re-fitted from turning to milling by means of a quick-change system.
   
The particularly heavy cast iron base is completely rigid and torsion-free.
