The machining centers are mainly used for machining workpieces with complex shapes, multiple processes and high precision requirements.
1. box parts
With more than one hole system and more cavities inside the parts known as box parts, such parts in the machine tool, automobile
car, aircraft and other industries are more applications, such as automobile engine block, gearbox body, machine tool spindle box, diesel engine cylinder,
gear pump housing and so on. Processing in the machining center, a clamping can be completed ordinary machine tools
60%

95%
of the content of the process,
in addition,
with the machining center's own precision and processing efficiency,
good stiffness and automatic tool change characteristics,
as long as the development of good technology
Process,
using reasonable special fixtures and tools,
can be solved box parts with high precision requirements,
processes are more complex and
improve productivity and other issues.
2. Complex surface parts
In the aviation, aerospace and transportation industries,
with complex surface parts are widely used,
such as cams,
aero-engine whole
body impeller, propeller, mold cavity. This kind of parts with complex curves, curved contours, or with non-open cavity
box or shell parts,
the use of ordinary machine tools or precision casting is difficult to achieve the predetermined machining accuracy,
and difficult to detect.
And
the use of multi-axis linkage machining centers,
with automatic programming technology and special tools,
can greatly improve its productivity and ensure
the shape of the surface accuracy, so that the automatic machining of complex parts has become very easy.
3. Shaped parts
Shaped parts are irregular parts, most of which require point, line, surface multi-station mixed processing (such as brackets, bases,
leaning molds, etc.)
. Processing of shaped parts, the more complex the shape, the higher the precision requirements, the more the use of machining centers can show its superiority
Vietnamese.
4. disk, set, plate parts
This type of workpiece includes a keyway and radial holes,
the end of the distribution of holes,
the surface of the disk or shaft workpiece,
such as with a flange
bushings, etc., and with more solenoid
L
machining of the plate parts, such as all kinds of motor cover. Motor cover, etc. Among them, the end of the distribution of hole system,
curve
surface of the disk parts often use vertical machining centers, radial solenoid
L
can be used in horizontal machining centers.
5. New products in the trial production of parts
machining centers have a wide range of adaptability and high flexibility,
replacement of the object of processing,
only need to prepare and enter a new program
can be realized.
Sometimes it is also possible to modify part of the program or use some special instructions to achieve processing.
such as the use of
Scaling function instruction can be processed with the same shape but different size parts, which for a single piece,
Small batch, multi-species production,
Products
Product modification and trial production of new products to provide a great deal of convenience, and greatly shorten production preparations and trial production cycle.
