Acecare OHT, Hardness testing machine for cylinders - ACECARE-OHT

Synopsis of online hardness testing machine for high-pressure cylinder (column class work piece)

Synopsis

The equipment uses in the Brinell hardness test for the steel cylinder after heat treatment. It can removes the work piece surface oxide layer automatically, carries on the Brinell hardness test automatically, the CCD system auto-acquire indentation, and form the Brinell hardness value automatically.

The special-purpose software can carry on the mass memory to the tentative data, and can carry on the statistics, the edition, and the analysis

Main feature:

Remove work piece surface oxide layer automatically

Superficial elimination depth is adjustable

The equipment controls PLC and the lower position monolithic integrated circuit by the superior PC idea

Experimental strength closed-loop control

The gauge head to be possible to complete the hardness test automatically;

The CCD measurement system completes the Brinell indentation survey automatically, and forms the production degree of hardness value

Double display monitor, software function is formidable (data processing, degree of hardness transformation and so on)

The precision meets the GB/T231.2 standard

Application scope:

It is mainly uses in determining the steel pipe class, pressure vessel class, drill rod class components degree of hardness value, can also use in other columns class
