CNC vertical lathe5 reasons for the collision and countermeasures:
(1) Programming errors: process arrangement errors, incomplete consideration of process undertaking relationship, parameter setting errors. The coordinate is set to zero at the bottom, but in practice it is zero at the top; the safety height is too low, resulting in the tool can not be completely lifted out of the workpiece; the path of the program should be analyzed and checked after the program is written;
(2) Error in the remark of the program list: the principle of replacing the old with the new shall be adopted when the program list is changed: the old program list shall be destroyed;
(3) Tool measurement error;
(4) The blank exceeds expectations, and the blank is too large to match the blank set by the program;
(5) Machine tool failure, sudden power failure, lightning strike causing knife collision, etc.

CNC vertical lathe is a kind of high precision, high efficiency automation and expensive machine tools, if due to programming, operation and other reasons, the machine collide, light is broken workpiece, damage to the tool, heavy is the tool motor, machine tool local damage, reduced accuracy, machine scrap, and even endanger the operator's life safety, the consequences are very serious.
Crash Prevention Measures for Numerical Control Vertical Lathe
NC vertical lathe programming directly affects the operation process of CNC machine tools, so the programming must be carried out in detail. To the programming and memory program, perforated belt, program single proofreading, calculation value proofreading are carefully completed. The main feature of the absolute position tester lathe is that even if the tool holder is not in the starting position, it will not affect the start of the CNC lathe. This kind of advanced numerical control machine tool has been applied to the lathe industry in our country. The addition of inductosyn and other equipment has improved the shortcomings of the original lathe. As long as the operator puts the machine tool in the invalid state of jump instruction after stopping work, it is OK.
