Vickers Hardness Testing Machines
We manufacture and supply Vickers Hardness Testing Machine in India. Our Vickers Hardness Testing Machine is simple & accurate in design. Vickers Hardness Testing Machine is suitable for measuring the hardness of precision metallic parts with wide testing range – from soft to hard & accurate results are guaranteed. Our Vickers Hardness Testing Machine strictly conforms to IS: 1754: 2002 & ISO 6507 – 2: 1997.
Vickers Testing Machine: How It Works
There is an indenter in form of a square diamond pyramid forming an angle of 136 degrees between its two opposite faces. The loads used in the Vickers Hardness Test may range from 1 to 100 kgf; these loads may be applied for approx. 10-15 seconds. Once the load is applied, the material is removed and the indentation on the material surface is measured.
Precautions To Take When Using Vickers Hardness Testing Machines
- Careful surface preparation is a must when using these machines to ensure accurate measurements
- Vickers Hardness is not to be used for routine testing as the entire process is quite slow.

- Wide testing range, from soft metal such as lead, up to the hardest, like hardened steel
- Tiny indentation allows testing of precision finished parts
- Thin sheet metal is perfectly tested because applied load is very small
- Same hardness number is obtained on the same specimen, regardless of the load applied
- Motorized loading and unloading cycle
- Built – in projection screen to get accurate result
To accommodate the high precision loading system & an optical projection screen the machine frame is designed sturdy. Specimen is to be placed on testing table. The test cycle is fully automatic. The accurate load is applied on a diamond penetration by means of a lever & weights. The load is removed automatically after a specific lapse of time. The objective is indexed with the test piece & the diamond indentation is projected on the measuring screen. The diagonals of the indentation can be measuring by means of the micrometer screw of the projection screen.
