CNC lathe machine is a kind of automatic machine tool equipped with a program control system.The control system can process the program with control code or other symbolic instructions logically and decode it, so that the machine tool can move and process parts.
Compared with ordinary machine tools, CNC machine tools have the following characteristics:
● High machining accuracy, with stable processing quality;
● Can be multi-coordinate linkage, can process complex shapes of parts;
● machining parts change, generally only need to change the numerical control program, can save production preparation time;
● Machine tool itself high accuracy, rigidity, can choose the favorable processing amount, high productivity (generally 3~5 times of the ordinary machine tool);
● Machine tool automation is high, can reduce the labor intensity;
● Higher requirements for the quality of operators, higher technical requirements for maintenance personnel.
Because CNC lathe processing is a high precision work, and its processing process concentration and parts clamping fewer times, so the use of CNC tools put forward higher requirements, in the choice of CNC machine tool processing, should consider the following aspects of the problem:
① The type, specification and precision grade of CNC tool should be able to meet the requirements of CNC lathe processing.
② high accuracy.In order to meet the requirements of high precision and automatic tool change in NC lathe processing, the tool must have higher precision.
High reliability.In order to ensure that the CNC machining will not occur accidental tool damage and potential defects and affect the smooth processing, the tool and its combination of accessories must have good reliability and strong adaptability.Precision metal machining
④ High durability.CNC lathe processing tools, whether in rough or fine processing, should have higher durability than ordinary machine tool processing tools, in order to minimize the replacement or repair of the sharpening tool and the number of knife, so as to improve the processing efficiency of CNC machine tools and ensure the quality of processing.
Good chip breaking and chip removal performance.CNC lathe processing, chip breaking and chip removal is not like ordinary machine tool processing timely by artificial processing, chip easy winding on the cutter and workpiece, can damage the knives and cut the workpiece machined surface, even hurt and equipment accidents, affects the processing quality and the safe operation of machine tool, cutter has good chip breaker is required and chip removal performance.
