10 Tips on How to Choose CNC Tools

CNC machining is a process that is considered for producing parts made from materials like metals, alloys, and engineering plastics. The value of high-quality, high-precision CNC parts and CNC machining cannot be understated. Almost every industry that uses CNC machined parts, either with its high-Precision CNC machines or with professional machining services, turns raw materials into specific components.

The CNC machining services in China offer compressive prototyping and advance product development solution. Right tool selection is important in machining. Learning to select the best tool, it will also help you work with ease.

Matching with the Machine Tool:

As there are right-handed and left-handed knives, it is crucial to choose the right tool. Right-hand tools apply for machine tools that rotate counterclockwise. Left-hand tools apply to the machine tools that rotate clockwise. If you have some lathes, left-hand tools, and others are consistent with left and rig

ht hands, then select the left-hand tools.

Although this type of tool has a wider processing range. It loses rigidity quickly, increases tool flexural deformation, reduces cutting parameters and is more susceptible to vibration of the machine. The size and weight of the tool that is changed by the manipulator of the machine tool are limited.

Matching with the Processed Material:

The most popular material to be processed in machining is carbon steel. Mostly, tools are based on optimized carbon steel processing design. According to the material, to be processed, blade grade is selected. Every China CNC machining parts manufacturer provides a series of tools, bodies and matching blades for processing materials such as high-temperature alloys, titanium alloys, aluminum, composite materials, plastics, and pure metals.

When you need to process these materials, choose a tool that matches this. Different brands have a different series of tools, showing what materials are suitable for processing.

Specifications of Tools:

A misconception is that the size of the turning tool selected is small and the size of the milling cutter selected is large. Large-sized turning tools have better rigidity. Large-size milling cutters take a longer time to cut. They are also expensive. The cost of large-size tools is greater than small-size tools.

Materials and Grades of Tools:

According to the performance and material being processed and speed rate, choose the tool material and grade. Select general tool grades for the material groups to be processed, such as coating alloy grades. Referring to the grade application recommendation chart will be a plus point.

A common blunder is to replace the similar material grades of other tool manufacturers to solve the tool life problem. If your tool is not ideal, then changing to another manufacturer is likely to bring similar results. For this, the cause of tool failure should be clarified.

Power Requirements:

It is important to make the best use of everything. Choose the milling machine with suitable power. If the workpiece and fixture allow power, then choose the suitable tool and processing parameters that enable to achieve the 80% power of the machine. Pay attention to the power in the machine tool and select the tool that achieves better cutting applications according to the effective power range.

Cutting Edge Number:

Purchasing a turning tool with twice the cutting edge does not mean paying double the cost. Advanced designs have increased the number of cutting edges for grooving knives, cutting knives, and some milling inserts. It is not commonplace to swap out an advanced milling cutter with 16 innovative insert for the original milling cutter with only four cutting edges. The number of effective cutting edges increases, which has a direct impact on table feed and production.

Choosing Modular Tool or Integral Tool:

Smaller cutters are better for the overall design, while larger cutters are better for modular design. For large-format equipment, customers frequently believe that by just replacing small and inexpensive parts, they may get a new tool. This is especially true for grooving and boring machines.

Choosing a Single Tool or Multi-Function Tool:

The compound tool is better suited to smaller workpieces. Drilling, turning, inner the whole processing, thread processing, and chamfering, can all be done with a multifunctional tool. Of course, multi-function tools are better suited to more complicated workpieces. When the machine tool is cutting, it can only benefit you, not when it is down.

Choosing Standard Tools or Non-Standard tools:

With the popularity of CNC machining centers, the shape of the workpiece can be noticed through programming instead of relying on tools. For this, non-standard tools are not required. Using special tools meets the needs of precise workpiece size, reduces procedures, and shortens the processing cycle. Non-standard special tools can shorten the processing cycle and reduce costs for mass production.

Chip Control:

Chips can reflect the cutting state of the tool. Good chips will destroy the processing while bad chips will not. The smaller the chip will be, the harder it is to break. For machines that are difficult to operate, chip control is a big issue. The material to be processed cannot be replaced. The tool can be updated, cutting speed, feed rate, depth of cut, and more can be adjusted.
