Project highlights

·Processing process characteristics - The machining process of the crankshaft hole is performed by a wire boring tool supported by a bearing. After the cylinder hole is finely finished, the cylinder bore is automatically measured, and the fine boring tool will automatically adjust before the next machining.

· Technical characteristics of flexible production line - In order to reduce the labor intensity of the operator and prevent the workpiece from bumping, the turning mechanism is adopted on the roller table. The SICK system is used to ensure the safety of the operator on the production line. The Barov system monitors the machining process and automatically prevents leakage processing. Repeat processing.

· Programming skills - full consideration of process safety and ease of operation. The FREEPOS function and the Magic Function key are designed. If the machining process is aborted, the tool can be arbitrarily retracted and can be processed continuously after reset.

Machine tool highlights

·Compatible engineering capabilities for various industries - Automotive, Fluid, Machinery, Rail, Safety and Safety High-level production: The duoBLOCK® series of horizontal machining centers enable users to be efficient and economical in less time. Mass production of complex work. From the development of time planning and feasibility studies to the turnkey delivery of complete production equipment, more than 80 technicians provide you with full service.

·Highest stability and less floor space for large workpieces and tools

The high static weight combined with the weight-optimized moving parts achieves high dynamics and maximum stability of the machine. In addition, the finite element-optimized duoBLOCK® structure enables the wide application of large clamping devices, as well as the comparison. Large parts and tall workpieces, all of which consistently maintain high precision on all indicators.
