How should we choose a reliable leveling machine?

A professional seller will ask the following questions when you buy a leveling machine:

①What is your flatness/leveling accuracy requirement?

②What material do you want? Is there much elasticity?

③Coil or sheet material? What is the length, width and thickness?

If the seller doesn’t ask the above questions, he will ask you to test run, and the effect is subject to proofing.

Buyers who have certain knowledge about leveling machine will ask: “④ How many rolls does the leveling machine have?”

Let’s explain the above questions with practical cases:

① The flatness is in denier, and 1 denier is about 0.01 mm. Usually a feeler gauge is used to measure.

 Feeler Gauge

② In terms of material, the price of stainless steel leveling machine is higher;

Materials with large elasticity (for example: thin red copper wafers shake in the hand) are generally difficult to achieve a good leveling effect.

③ Coil material can achieve better leveling effect than sheet material.

On the premise of achieving the same flatness, the price of leveling machine rises linearly with the material width and thickness.

④ Generally, the more rollers, the higher the flatness.

The half leveling machine has the fewest rollers, i.e. 3 upper rollers and 4 lower rollers (7 rollers)

It is generally used for coil materials and sheets with low flatness requirements (seemingly flat).

 3 Upper and 4 Lower Leveling Rollers of Half Leveling Machine

If a 4mm thick stainless steel plate wants to achieve a flatness of less than 0.4 mm (40 denier)

A precision leveling machine with 9 upper rollers and 10 lower rollers (19 rollers in total) is required

4mm Thick and Flatness Less Than 0.4 mm

Summary: When purchasing a leveling machine, it is necessary to clarify the leveling accuracy. If the accuracy requirement is not high,

You may choose a leveling machine with 3 upper rollers and 4 lower rollers or with 4 upper rollers and 5 lower rollers;

When the coil material is small, you can also choose a material rack and leveling integrated machine;

To require high accuracy, you can choose a leveling machine with more rollers, and reject those with few rollers.
