Important Features Of CNC Tools

Apart from being different types of tools, CNC tools have different features that define their cutting performance, efficiency, versatility, and applicability. Important features of CNC tools include:

• Material Compatibility

  CNC tools are compatible with different materials, like metals, plastics, wood, and composites, depending on their type. Common CNC materials include stainless steel, titanium, aluminum, and brass in CNC machining, which are used in the aerospace and automotive industries. CNC tools like CNC laser cutters and CNC stone cutting machines cut through thinner metals and stones.

• Cutting Edges

  Cutting edges and points on CNC tools' work end must be sharp to enable cutting through workpieces. Carbid and cobalt steels are common materials for making CNC tool cutting edges. Tungsten carbide edges are used in machining hard metals. The geometry of the cutting edge plays a role in the type of cut made, like smooth or rough.

• Speed

  CNC tools operate at different speeds, depending on the type of material and project. CNC routers, for instance, operate at speeds of 30,000 RPM, while CNC lathes operate at speeds around 70 RPM to 3000 RPM. Laser cutters operate at speed values ranging from 5 to 300 mm/s. The feed rate is a measure of how quickly the cutting tool or workpiece moves toward each other to make a cut.

• Precision

  CNC tools cut pieces with great accuracy and high repeatability compared to manual tools. Precision is measured in micrometers or millimeters, while repeatability is the ability to make successive cuts the same way even after long hours of production. High levels of precision in CNC tools depend on various factors, including material, operator skill, maintenance, and cutting speed.

• Power

  Power is an important attribute in determining the cutting speed and material thickness. Higher power CNC tools can handle more extensive and complex cutting operations. CNC tools have power ratings in watts or horsepower, while higher-rated spindle motors have greater power.

• Customization

  CNC tools offer varying levels of customization, enabling the production of unique or specialized parts. This is usually done on a computer through a CAD program. Customization is useful in industries like furniture and aerospace, where parts must be specially made. It is also helpful in prototyping, where numerous tests are carried out on different designs before investing in a final product.

How To Choose CNC Tools

• Determine CNC Tool Requirements

  Identifying the material type, thickness, and outline of the desired CNC parts helps determine the most applicable tool. Find out if there are any industry standards or tolerances that have to be met for the particular applications. Consider the required production volume to decide if a high-speed or standard CNC machine is necessary.

• Assess Material Compatibility

  Common CNC materials include metals such as aluminum, brass, stainless steel, and titanium, as well as plastics, wood, and composites. Some materials are easy to cut, while others are hard and require CNC tools with higher durability and toughness. Check the serviceability of the tools with optional coatings, which increase the wear resistance of the tools with extended life span.

• Evaluate Cutting Edge Features

  Different cutting edge geometries available have varying effects on the cutting process. For instance, sharp cutting edges are best suited for fine cuts, while blunt edges work best for materials that are hard to cut. Review offer tools with carbide or cobalt steel cutting edges to increase durability. Find tools with specialized coatings like TiN, which reduce friction and enhance edge.

• Consider Precision and Tolerances

  Determine the level of precision and the required tolerances for the specific CNC machining and cutting projects. Tolerances value range from ±0.01mm to ±2mm, depending on the type of industry. Accuracy refers to how close the cut is to the desired outcome, while precision is the ability to replicate the same cut consistently. Contact a CNC facility and ask about the standard and commonly used tolerances.

• Assess Customization and Application

  Most CNC tools have to be applied in certain types of projects, while others are more versatile and can be used in numerous projects. For instance, a CNC plasma cutter is ideal for metals, while CNC tools are also applicable in the cutting-making machine for stone cutting through a diamond blade. Check the CNC tools for special projects that require special tools, like 3D printing prototypes requiring a 3D printer CNC router.

• Budget Considerations

  It is recommended to purchase inexpensive tools compatible with the project requirements before making any costly investment. After gaining an understanding of the needs and demands of the project, gradually investing in better quality, precise, and durable CNC tools is a good strategy. Balance between the initial costs and long-term benefits requires an analysis of the project.
