Guide of Face Mills: Types, Specifications, and Materials

Posted on by

Face mills are primarily used for milling a face on the surface of a plate or bar. They are predominantly used to cut with the ends of the cutter rather than their sides. The term “face” refers to the creation of a flat face on the workpiece. Face mills often have a larger diameter than the width of the workpiece being faced, so that the surface can be processed in one pass.

 

Types

Face mills may be of solid construction or with holders and inserts. They can be used with a number of end or tip geometry options, including square end, ball nose, radius tip, and chamfer tip.

 

  • Square end tip geometry for face mills have a square or straight end that features no radius, chamfer, or other finish.
  • Ball nose face mills tips have a “ball nose” whose radius is one half of the cutter diameter. This type of face mills tip is useful for machining female semicircle grooves of radii.
  • Radius-tipped face mills ends are straight flutes with ground radius on the very tip.
  • Chamfer tip ends feature an angled section of the side or the end. These tips produce an angled cut of chamfered edge on a workpiece.

 

Specifications

When selecting a face mill, consideration must be made to the desired finish type. There are typically two finish options: roughing/hogging and finishing. Roughing/hogging mills are designed so that the machine geometry, flutes, and materials can be used for rapid and heavy material removal. They are typically used to machine workpieces close to the desired finishing dimensions, where a finishing face mill takes over and produces closer tolerances and higher-quality surface finish.

 

Other considerations for face mills include cutter size and construction criteria. Size considerations for face mills relate to the:

 

  • Cutting Diameter
  • Shank Or Arbor Diameter
  • Flute Or Cutting Edge Length
  • Overall Tool Length
  • Radius Dimension And Angle

 

Construction options for face mills include the number of flutes of cutting edges. This number can vary with the cutter diameter, milling material, and other factors. Two-flute face mills are often used with ductile materials that produce long chips. Face mills using a higher-number of flutes can be used to minimize chip load and vibration.

 

Materials

The material of the face mill is important for understanding the level of cutting the machine can handle. Materials like carbide, cobalt, and diamond are hard and can be used in high-speed applications, whereas materials like steel are used for general metal machining. Other material options for face mills include micrograin carbide, which is used most-often in surface finishing applications, and ceramic.

 

Coatings for face mills are important considerations as well, as they can provide additional protection against corrosion and abrasion, increase the tool’s hardness, provide lubrication and smoothness assistance, and improve the overall lifetime of the tool. Other considerations and options for face mills may also be available depending on the manufacturer.

Machining Performance Reveals Opportunities for Efficiency Gain, The Value of Tooling Choices That Save Time Will Be The Important Key

Posted on by

As more sophisticated insight into machining performance reveals opportunities for efficiency gain, the value of tooling choices that save time will become increasingly clear.

 

The promise of Industry 4.0 is great news for the adoption of advanced cutting tools. The reason: In interconnected manufacturing systems in which comprehensive data reveal the performance of the system, the impact of an advanced tool becomes clear.

 

Historically, the lack of clarity about manufacturing performance has been the main impediment to shops embracing high-end cutting tools. Tools typically account for just 3 percent of the per-piece production cost of a machined part. However, a tool’s price tag is more visible than its benefits. This fact leaves manufacturers frequently pursuing cost-saving steps that have little impact. For example, at 3 percent of unit cost, finding tooling that is one-third less expensive will only cut the per-piece part cost by 1 percent. Something similar is true of tool life: Even doubling tool life will only cut cost per part by 1.5 percent. However, finding tooling that provides for significantly faster machining or reduced non-cutting time enables each unit of machine and labor time to deliver more parts, likely cutting the cost per piece by 10 or 15 percent.

 

This argument makes sense in the abstract. The problem is, it can be hard to marshal the data to prove this case as it applies to a specific tool in a specific cut. That is where Industry 4.0 comes in. We are moving into a world in which manufacturing systems increasingly do marshal data such as this, and manufacturers increasingly make use of it.
