Need automatic grinders? We’re talking about a surface grinding machine, not a coffee grinder, for your metalworking shop?

LeBlond has cost-friendly K.O. Lee manual and automatic surface grinders that more than measure up quality-wise to the more expensive options, giving you a comparable grinding finish.

If you are having trouble deciding which way to go – automatic or manual– read further for a better understanding of the difference between the two options.

What is Surface Grinding?

Surface grinding is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on workpiece surfaces. This will also attain a desired surface for a functional purpose.

How is a Surface Grinder Used?

A surface grinding machine uses a round, rotating, abrasive grinding wheel that remains stationary, but rotating. At the same time, the feed table with the work attached runs in a left-to-right reciprocating motion under the grinding wheel.

The exact amount of material to be removed is determined by lightly touching off on the work as the grinding wheel rotates and feeding the grinding head down a certain distance.

Manuals or Automatics – What is the Difference?

The clear difference between automatic and manual surface grinders is in the way they are handled while performing grinding operations. From this point, with manual surface grinders, the operator would then need to run the table left and right with one hand wheel while cross-feeding with the other hand wheel.

If doing automatic surface grinding, the operator would be able to run the table left and right automatically while cross-feeding automatically, as well. They would simply need to set the down feed and stroke.

The Benefits of Surface Grinding

Surface grinders are able to grind very hard or abrasive materials such as:

  • Cast iron

Grinding

  • Mild steel
  • Stainless steel

Grinding

  • Aluminum

Grinding

  • Brass

Grinding

  • Some plastics

Other benefits of surface grinding include:

  • A high degree of dimensional accuracy
  • Produces surface textures of a very high finish
  • Tooling is more cost efficient
  • Work holding is simpler because of the magnetic chuck

Advantage of Automatic Grinders

Surface grinding using automatic grinders is much more cost efficient for mass production as they are able to produce quality work that is repetitive.

Advantage of Manual Grinders

However, when the required machining cycle is relatively slow, and for special workpieces or machining tasks, manual surface grinding can handle more complex machining tasks that are difficult to program.
