In the process of CNC machining, the
selection of the tool is very important. The choice of the tool determines the quality
of the workpiece, because there are certain requirements for the tool
performance of CNC machining. Different machining parts and different batches
determine the choice of tools. Let's take a look at the factors that affect the
choice of CNC machining tools.

(1) Production batch
From the processing cost, there is a
certain influence on the selection of the tool. If it is a certain part of mass
production, special tools are needed, which is relatively cost-effective.
However, if the tool is used to produce a single piece or a small batch, the
tool is relatively expensive, so it is more appropriate to use a standard tool.

(2) Machine type
The effect of the CNC machine used to
complete the process on the selected tool type. High productivity tools can be
used to ensure the rigidity of the workpiece system and the tool system. For
example, high-speed cutting tools and large-feed turning tools.

Different types of tools are used depending
on the requirements of different machining schemes. For example, the hole can
be machined by drilling and reaming, and it can also be machined with a tool
such as a file. The final selection is based on the machining plan.

(4) Workpiece size and shape
Different dimensions of the workpiece have
a certain influence on the type of tool and the choice of specifications. For
example, special surfaces require special tools for machining.

(5) Machining surface roughness
The roughness of the machined surface
affects the shape and cutting of the tool. For example, when the blank is
rough-milled, a coarse-tooth milling cutter can be used, and in the case of
finishing, it is preferable to use a fine-tooth milling cutter.

(6) Machining accuracy
The type and shape of the finishing tool
are affected by the machining accuracy when selecting, for example, the
machining of the hole, drilling, reaming, reaming and boring according to the
precision of the hole.

CNC machining has high precision, high
efficiency, relatively concentrated machining process and fewer parts clamping
times, so it has high requirements for machining CNC tools. From the point of
view of the performance of the tool, the CNC tool needs to be higher than the
tool used in the ordinary machine tool. Be sure to pay attention to the choice
of tools.
