CNC turning parts has significant advantages over traditional turning methods, which are mainly reflected in the following aspects:
First, high precision and high stability
High precision: the positioning accuracy and repeated positioning accuracy of CNC lathes are very high, usually the positioning accuracy can reach 0.01mm, and the repeated positioning accuracy is 0.005mm. This ensures high dimensional accuracy of the machined parts and minimal deviation from the design drawings.
High stability: Because the CNC lathe adopts the ball screw nut structure and various gap elimination structures, the error of the mechanical transmission is reduced as much as possible, and the CNC system can also automatically compensate the error, thus ensuring the stability of the processing quality.
Second, high efficiency
Reduce auxiliary time: CNC lathe can process multiple machining surfaces in a single clamping, eliminating many intermediate processes in ordinary lathe processing, such as marking, size detection, etc., thus greatly reducing the auxiliary time.
High cutting efficiency: The spindle speed and feed range of CNC lathes are wider than that of ordinary lathes, and the most suitable cutting parameters can be selected for processing, improving cutting efficiency.
Continuous machining: When using a CNC turning center machine with a tool bank and an automatic tool changing device, continuous machining of multiple processes can be achieved, further improving production efficiency.
Third, flexibility and adaptability
Flexible programming: The programming of CNC lathes is very flexible, and different processing needs can be achieved by writing appropriate programs, and it is adaptable.
Strong adaptability: CNC lathe has strong adaptability to the processing object, and when the product transformation and design change, just change the program, without re-designing the tooling.
Suitable for complex parts processing: CNC lathes can realize multi-coordinate linkage, and can process complex parts, such as multi-arc and other complex parts.
Fourth, cost savings
Reduce scrap rate: CNC lathe processing precision is high, the quality is stable, can reduce scrap rate, reduce material waste.
Save tooling costs: CNC lathe processing generally does not require a lot of complex process equipment, complex shape, high precision parts can be processed by preparing processing programs, saving tooling costs.
Low comprehensive cost: Although the initial investment of CNC lathe is large, in the case of single piece and small batch production, it can save process equipment costs, auxiliary production hours, production management costs and reduce the scrap rate, so it can obtain good economic benefits.
Fifth, promote new product development
Shorten the development cycle: CNC lathe processing does not need a lot of complex process equipment, through the preparation of processing programs can be processed complex shape, high precision parts, greatly shorten the product development cycle.
Convenient for product improvement: When the product is modified and the design is changed, only the program needs to be modified, and there is no need to redesign the tooling, which provides shortcuts for the development of new products, product improvement and modification.
To sum up, CNC turning parts with its high precision, high efficiency, high flexibility, low cost and promote the development of new products and other advantages, in the modern manufacturing industry has been widely used.
