What factors are related to the machining accuracy of cnc machining
center dies
In the process of mold processing, the machining center has higher
and higher requirements for precision and surface processing
quality. In order to ensure the mold processing quality, we should
consider the selection of machine tools, tool handles, tools,
processing schemes, program generation, operator requirements, etc.
1. High precision and high speed machining center
With the improvement of product design requirements and the
development of high-speed and high-precision processing technology,
the quality of mold NC processing has been greatly improved, the
mold processing speed has been greatly improved, the processing
process has been reduced, the mold production cycle and clamping
times have been shortened, and sometimes the time-consuming bench
worker repair work can be eliminated. High speed and high precision
machining of molds has gradually become one of the important
contents of technological transformation of mold manufacturers. It
is inevitable that high-speed CNC machining centers replace
traditional low-speed machining, and the development of mold
manufacturing technology will also bring us more rich product
experience.
2. Use appropriate tool handle structure
The use of high-speed and high-precision machining centers will
also drive the updating of related process equipment. In
particular, the impact of tools on NC machining quality and tool
shank will become prominent. In the rotary cutting tool processing
system, the chuck is closely connected with the machine tool (or
its combination) to ensure the realization of the tool processing
performance. The interfaces between machine tools and tool handles
commonly used include HSK hollow tool handles and BT tool handles.
The taper of the taper shank interface between the machine tool
spindle and the BT tool shank is 24:7. This kind of tool shank
connection mode is suitable for traditional low-speed machining.
Because the BT tool shank and the machine tool spindle are only
tapered, under the action of high speed centrifugal force, the
taper clearance will increase, which will affect the quality of NC
machining. Generally, when the spindle speed exceeds 16000 rpm, we
will need to use the HSK hollow handle. The HSK cutter bar
positioning structure is over positioning, providing standard
connection with the machine tool. Under the pull of the machine
tool, ensure that the short cone and end face of the cutter bar are
closely matched with the machine tool.
3. Select a suitable tool for machining
The rational use and selection of cutting tools will be an
important factor affecting the quality of NC machining. Cemented
carbide tools are more and more widely used. In high-speed
machining, coated cemented carbide will replace most of the sharp
steel tools, including simple tools such as reamers, ball cutters,
and boring cutters. Coated cemented carbide will play an important
role in high-speed machining tool materials and be applied to most
conventional machining fields.
Generally, we know that we will use large diameter tools for rough
machining. In order to save costs and reduce the difficulty of tool
manufacturing, we will use machine clamped carbide inserts to make
rough machining as much as possible; In semi finish machining, the
insert cutter with high speed and high feed is used to make the
semi finish machining run fast; When finishing, try to use
high-precision round mirror blade and carbide cutter bar to ensure
the strength of the tool and cutter bar, which will save the
expensive cost of using integral alloy cutter while maintaining the
machining accuracy. During processing, we also need to pay
attention to that the radius of the inner contour fillet on the
finishing part must be greater than or equal to the radius of the
tool. The tool with a radius smaller than the corner fillet radius
is selected for processing in the way of circular interpolation or
oblique interpolation, which can avoid the phenomenon of over
cutting caused by linear interpolation and ensure the quality of
the die finishing.
