Small cup wheel straight line edging machine

Machines comparatives

 

Small cup wheels straight line edging machines

 

Small means machines from 4 to 6 cup wheels ( even seven for the machines with a felt in last position).

They have in general:

-4 Wheels : 1 diamond wheel + 1 polishing wheel + 2 stone wheels for the arrises.

-5 Wheels: 1 diamond wheel + 1 polishing wheel + 1 Cérium wheels ( white one) + 2 stone wheels for the arrises.

-6 Wheels : 2 diamond wheels + 1 polishing wheel + 1 Cérium wheels ( white one) + 2 stone wheels for the arrises.

With this kind of machines we can have good results in certain conditions. The important thing is to understand where are the limits.

 

 

4 Wheels

 

-With only one diamond wheel the limits are on the speed and on the thickness. The technical carasteristics of the diamond wheel are a balance between speed and quality. The diamond grit size must be medium. This means the glass removal can’t be important and it remains on the edge small lines due to the grit size.

-Only one wheels for arrises means to use a synthetic stone wheel which must both remove glass and polish it.   With this kind of wheel it is not possible to have large arrises ( no important removal capacity). This means it will be difficult to have a good arrise quality for thickness beyong 10 mm. If you want to work on thickness beyong 10 mm, you are going to have a very fast wheel wearing, small arrises and a polishing difference with the edge.

-With only one polishing wheel you must have a very abrasive polishing wheels ( coarse grit size) to remove the diamond lines on the edge.

So these machines can be a solution for maximum10 mm thickness, very small batches and no bright polishing.

 

Five wheels

-The limits are the same than with the for wheel. The difference and advantage is that the fifth wheel is a cerium wheel. So you can have a bright polishing.

 

Six Wheels

-We are here on the boundary with industrial edging machines.

The single differnece is on the arrises with the same remark than for the four wheels. Only one stone wheel to create and polish the arrises. pour créer et polir les arêtes. This problem can be more important because the number for diamond and polishing wheels is proper to edge with a good speed and a good quality up to 19 mm. So for hight thickness the arrises are too small.

 

This machines range is the one where there are important difference between the machines. These machines are small, so easier to build. There are big difference in prices, technical, quality and service.

The comparaison include 9 suppliers, 21 machines and 23 different datas.

This machine is often the first one a company buy. So it is also interesting to consider, in case you want to grow and buy in the future a more important machine, the value of the trade mark in secondhand market.
