The Boley BC42-X2 is a high precision universal CNC lathe designed for efficient, economical production of both simple and complex workpieces in small or large batches. One hit machining of complex parts is achieved using powered tools and a sub-spindle, together with spindle indexing a C-axis.

The main and sub-spindles can be synchronised to facilitate alignment or angular relationship of front and back operations.

• Fixed headstock with a built-in motor, C-axis and electromechanical workpiece clamping.
• Fully functional sub spindle with optional, electromechanical workpiece clamping, digital synchronisation and synchronisation control.
• Support drive with Mechatronic technology for shorter cycle times and increased operational safety.

The construction of the BC, with slant design of the large, robust, vibration-free bed provides greater swarf clearance for efficient production. Good accessibility for the operator through the large sliding doors. The transparent sliding door provides a full view into the workspace. State-of-the-art built-in spindle and axis drives mounted on precision guideways provide super precision and response.

Finished parts are removed from the working area by the means of a workpiece slide which is controlled by the 'M' function. This slide and the workpiece receptacle both have a protective lining to avoid damage to the finished part. As an option, the machine can also be fitted with a workpiece conveyor.

A large step into the future is the newly designed turret with it's Mechatronic technology. The main advantages are the improved operational safety and the ultra-short indexing times.

A one-second indexing time provides a high level of production capability. The BC42-X2 therefore represents a revolutionary development, as a machine concept, for the machining of the most demanding components.

All primary and secondary drives are electromechanically powered on the BC42-X2. The servo motors are 'intelligent' and 4communicate directly and independently with the powerful CNC system without any delay. The Mechatronic technology ensures a high degree of operational safety.

The BC Mechatronic CNC control with Windows 95 and 64 bit RISC processor ensures that all machine functions are performed and controlled in the shortest of times. This includes the processing of extensive program blocks in the minimum of time.

The PC-based control is user-friendly and programming is simplified with logical guidance for the operator.

This innovative control concept has been developed to provide maximum adaptability for the future. An Internet interface for external dialogue is in the preparation phase at present. Each model is supplied with a built-in modem to facilitate remote access for diagnostics and servicing purposes. This can dramatically reduce downtime associated with programming errors etc.

Through the addition of an X2 axis to the sub spindle, dramatic savings can be made in terms of cycle time. The new X2 model enables simultaneous, independent machining of the front and back end of the workpiece, on centre-working and turning / boring of inside and outside diameters. This, in effect, provides you with the benefits of a twin turret machine with the significant cost savings of a single turret model.

The associated reductions in cycle time and increased productivity will ensure you maintain a competitive edge.

Supporting Software Options
Remote monitoring and diagnostics	Allows the Service Team to remotely control your machine and provide you with support via. the Internet (if your company has a suitable broadband / leased line connection).
Alarm alerting system	Automatically inform designated people in your organisation if an alarm occurs on one of your Citizen machines. Up to 100 machines can be simultaneously monitored. The message delivery can be via. voice message to land-line or mobile, SMS text message to a mobile or Email. Multiple recipients can be specified for each machine. This system is ideal for those running the machine unattended overnight.
CNC Program Editor	An easy-to-use Windows-based CNC program editing system with built-in support for program transfer over RS232 and (optionally) Wireless LAN. Many support functions are included such as code templates for common processes and program validation checks.
