What is The Difference Between A Pivot Hinge And A Side-Mount Hinge?

Posted on by

A pivot hinge is secured top-to-bottom. It’s this hinge type that allows a door revolving door to spin, while staying in place. Only most pivot-hinged shower doors mount top-to-bottom at the corners of the door, allowing the door to swing 180 degrees in each direction. (Pivot hinges that are center-mounted create a true revolving door.)

 

Pivot Hinge Pros

  • Pivot hinges are mostly attached at the far corners of the door, creating an uninterrupted frameless view.
  • Pivot hinges that mount floor-to-ceiling can reduce the cost of glass fabrication.
  • Pivot hinge doors carry the weight at the bottom of the door, and are thus very stabilized by a structurally sound floor.

 

Pivot Hinge Cons

  • Pivot hinges can’t be sealed for extra water protection.
  • If your pivot shower will not run floor-to-ceiling, then a metal header is required for the pivot to attach to a top structure.

 

A side-mount hinge is similar to the door hinges in your home. One side of the hinge is anchored on the side of a frameless glass door. The other side of the hinge is mounted to a wall or another glass panel.

 

Side-Mount Pros

  • Side-mount wall hinges avoid the need for a header or top support bar, which detracts from a frameless look.
  • Side-mount hinges can be sealed to improve water tightness.

 

Side-Mount Cons

  • Using side-mount hinges to mount a glass door to another glass panel (b/c no wall is available), may require a top header.
  • Using glass-to-glass side-mount hinges means a second glass panel gets precision cuts to hold its end of the hinge. This adds to the total project cost.

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.
