Have Preliminary Understanding of The SEMS Screws

Do you know what are SEMS screws and how do they use? If you don’t understand, try to read this article to have preliminary understanding of the SEMS screws.

 

Washers are often used in combination with screws to improve the structural integrity of an assembly. Typically, they are separate components. However pre-assembled screws and washers – the SEMS screws, have simplified and improved efficiencies in many manufacturing processes.

 

What is a SEMS Screw?

SEMS Screw - Hex Flange Head Self Drilling Screw Harden RuspertA SEMS Screw is a generic term used to describe a screw pre-assembled with a free-spinning lock washer. It is a permanent assembly with the washer held in place by the major diameter of the screw thread being larger than the hole of the washer. The SEMS screw is simple, easy to use and available in many different styles making it well suited for many applications.

 

Advantages of the SEMS Screw:

 

  • Low cost and widely available
  • Increases productivity by eliminating hand assembly of individual components
  • Permanent assembly assures that the washer is not dropped, lost or forgotten
  • Ease of use with hand drivers and in automated production programs
  • Available in most screw and washer combinations

 

Key Considerations When Choosing SEMS Screws:

 

  • Select the correct configuration for the specific task at hand
  • Good design ensures savings in the long run
  • Proper finishes perform optimally and are aesthetically pleasing
  • Ease of use, particularly in difficult spaces

The Way of Choosing the Right Surface Grinder

The surface grinder you need will depend largely on the material that needs grinding. For instance, if any metal surface needs grinding, the grinding wheel should be made of a highly abrasive material, and it should have numerous cutting niches embedded in it. On the other hand, for grinding a wooden surface, what you need is a lesser abrasive wheel.

 

The Types of Surface Grinder

 

There are two basic types of surface grinders, and they are:

 

  • The Planer-type
  • The Rotary-type

 

In the Planer-type, the grinding wheel remains stationary, while the worktable moves in a back-and-forth motion. This movement is controlled either manually or through some hydraulic drive system. These grinders are selected when overall grinding is required once the machine component has left the foundry.

 

In the Rotary type, the grinding wheel rotates, as does the circular worktable. These rotary surface grinders are selected when the precision machine parts require grinding, before being fitted into its housing. In both the surface grinder types, the safety hazards are well taken care of, and because of this, accidents rarely happen.

 

Things to do After a Surface Grinding Job Is Over

 

After a surface grinding job is over, the entire work station should be cleared of debris. If the work was done on a wooden material, the saw dust may be supplied to those who make composite boards, while the shavings from the metal surface can be sent to steel mills for melting.

 

However, what matters most is the safe clean-up of the work area, as otherwise, someone might get injured from carelessly thrown bits of metal shavings. Also, the surface grinder needs attention after each operation. It should be checked for any flying debris that blocks its air vents or any damage caused to the moving parts.
