PURPOSE:To avoid the stopping of an entire machining line and enable the improvement of working efficiency by making machines free from a load in the order of transfer and mounting a tool for different purposes. CONSTITUTION:When a secondary cylinder block W2 has been transferred on a conveyor 17 in the course of machining a primary cylinder block W1, the block W2 is detected by a sensor 23, thereby stopping the conveyor 17, and a machining line 1 continues to work. And the conveyor 17 stops only for one-cycle time of said line 1 and there appears a condition wherein no block W exists on a carriage 11-1. In the succeeding cycle, the conveyor 17 works and a block W2-1 is transferred into the line 1 and positioned on the carriage 11-1. The carriage without a block W moves to the position 11-2. In this way, a carriage without any workpiece appears between blocks W1 and W2, and honing head exchange work for the block W2 is carried out during the cycle time when the carriage 11-2 is not loaded with a workpiece. |
