What are you looking for?
high precision cnc machining is practically like with a computer. It works according to a given program. In the form of a certain number chain, the order of movement of the working "bodies" of the machine in the process of processing a particular material is recorded - that's all. You just need to understand and use.
The processing process takes place as follows:
the input device “reads” the program
converts it into signals
the intermediate memory “remembers” all this
and stores it for some time.
The active control unit compares those specified by the program using a feedback system displacement. And the actuator implements the received signals. The mechanism is up and running.
The machine performs basic and additional functions. The basis of work is the control of feed drives, and changing the speed or type of tool is an additional step.
In high precision cnc machining, there is a very convenient changeover system. Nothing needs to be unscrewed, unscrewed and screwed in again. It is enough only to replace the entered information. And the machine-worker will immediately perceive it.
And start a new business, honing the part ordered by the new program. It is this very moment that justifies the convenience of using CNC machines - a very quick reorientation.
What is the difference between metal processing and high precision cnc machining? Here you don't need to think for a long time. In the first case, the whole process is intended for the worker who serves the machine. In the second, a programmer is involved. His task includes a very thorough study of the technical process. It comes with the smallest details.
By the degree of versatility, CNC machines are distinguished as:
universal
designed for various operations
a wide range in small-scale production
for processing the same type of workpieces of different sizes
and special for processing workpieces of the same name and one size in bulk production.
Any of these classified machines performs their work accurately, quickly and practically without interruption.
In addition, automatic high precision cnc machining ensures:
consistent quality
the required roughness
dimensional accuracy and shape
It ensures the identity of all parts of the same batch. And one more nuance: an automaton is not a person with fatigue or a bad mood characteristic of all living things - it will not fall asleep, it will not fail, it will not make a mistake.
Automation of the machine cycle allows you to turn any universal machine into a semi-automatic or automatic. It provides the possibility of multi-station service. Moreover, it has a very positive effect on labor productivity.
CNC lathes, as a rule, are used when processing complex workpieces. It comes with multi-stage or with a curved surface. CNC turning is made easier by the fact that the automatic cycle provides multi-station service.
It means that the quantity is not created at the expense of quality. The tapping system is perfect for machining complex workpieces at high speeds.
With modern technology, high precision cnc machining becomes less time consuming and tedious process. You might even say not tiresome at all. After all, the main work in this case is to create a program. And a modern CNC will ensure its execution according to a standard cycle.
The state-of-the-art high precision cnc machining now gives the go-ahead for the implementation of the so-called end-to-end process. When all stages of creating a product, from development to the output of the finished product, are computerized and automated.
CNC lathes make up the lion's share. The main number of similar technological machines in the park. Carrying out their traditional technological operations, such as:
boring and turning surfaces
tapping
drilling,
Smart machines approach the process so precisely and meticulously that the processing of parts becomes something akin to cloning.
When milling, we are usually interested in the following nuance: how to achieve high quality at low cost. And here, too, CNC machining will play a positive role.
Rough or finish milling is carried out, without a difference. In either case, the details in programming cannot be ignored. Milling CNC metal - is a tricky business. Though it is not associated with noble metals.
Therefore, in factories where new equipment appears. No matter who does not work. Specialists undergo training, some even abroad.
So, by means of high precision cnc machining, as the most common of machining, three types of processing of simple surfaces are carried out. And the technological capabilities of CNC machines of the milling group are determined by their:
design
technical characteristics
layout and accuracy class
One way or another, milling on CNC machines is characterized by high productivity. And it allows you to get parts with a geometrically perfect surface. By the way, milling can easily replace grinding by using cutters equipped with modern cutting materials.
high precision cnc machining is used in many areas of life. Such services are becoming a necessity in:
the advertising business
in the woodworking and
native metalworking spheres
CNC milling is designed to create a perfect part, even with a complex and hard-to-reach surface. The complexity of the form is not a hindrance if the machine has high precision and cleanliness of processing.
Large, small batches - it makes no difference for a CNC machine. Working according to a given program, the machine easily copes with milling any volume of products.
By reducing scrap rates and increasing productivity, these machines are ready to work for the people day and night. In the old days, they would definitely have been awarded the title of heroes of socialist labor.
Obedient to the program, high precision cnc machining can process anything. And how we want, allowing a person to be in charge of all processes. The role of the worker is reduced only to monitoring the operation of the machine.
