Straight Flutes Engraving End Mills

Product Description

 

Engraving End Mills with straight flutes are specialized tools that are ideal for milling plastics and composite materials like epoxy and glass. Unlike helical general-purpose end mills, these single-ended mills have a zero-degree helix, resulting in better surface finishes and reduced fraying of the edges. They are commonly used for special profile milling applications.
Available in square and ball nose end geometries, these mills come with two or four flute configurations. This allows for greater versatility in achieving desired milling results. Additionally, they are offered in solid carbide or PVD AlTiN coated variants. The choice of material and coating depends on the specific requirements of the milling job.
Engraving End Mills are manufactured in a wide range of diameter sizes, ranging from 1/8" to 1". This ensures that there is a size suitable for various applications and milling needs.
In summary, Straight Flutes Engraving End Mills are high-performance milling tools designed for specific applications in plastics, epoxy-glass composites, and special profile milling. Their straight flute design minimizes fraying and provides superior surface finishes. With options for square or ball nose end geometries, two or four flute configurations, as well as solid carbide or PVD AlTiN coatings, these mills offer versatility and precision in a wide range of diameter sizes.

 

The number of cutting flutes in each tidbit can vary based on its diameter and purpose. The strength of the tool increases with more flutes, but it reduces space for chip flow. Using a single flute tool allows for faster cutting, while a three or four-flute cutter provides a smoother finish.

 

The tool used for machining materials such as acrylic or PMMA can produce excess heat due to the increased friction caused by an increased number of flute, potentially resulting in melting of the material. To mitigate this, tools with fewer flutes are often used to minimize the heat generated. In an ideal scenario, the tool should not produce any waste materials that are hotter than the ambient room temperature. However, this can vary significantly based on the material being machined.

 

 

Features

 

Solid carbide fine-point tips are highly effective for cutting lettering, numbering, and intricate designs on various metals and composites like aluminum, fiberglass, and titanium. These tips offer superior hardness, strength, and wear resistance compared to high-speed steel and cobalt steel, resulting in extended lifespan and impeccable finishes on tough materials. However, their extreme hardness also makes them brittle, necessitating a rigid setup such as a CNC machine to prevent breakage. Moreover, these tips are center cutting, enabling plunge cuts into surfaces for added versatility and precision.

 

When it comes to demanding jobs that require high speed and involve hard materials, Straight Flutes Engraving End Mills are the ideal tool. These end mills are particularly well-suited for longer production runs and offer superior wear resistance compared to uncoated end mills, particularly when used at high speeds. Additionally, they are able to dissipate heat much more effectively, making them perfectly suited for jobs where heat is a concern. Even in high temperatures and when used without lubrication, the special coating on these end mills creates a layer of aluminum oxide that transfers heat away from the tool and into the chips, ultimately keeping the tool cool and increasing its longevity.
