VICKERS HARDNESS TESTING MACHINE - SE VM-50

VICKERS HARDNESS TESTERS - SE VM-50

SE make Vickers Hardness Tester is simple & accurate in design. It is suitable for measuring the hardness of precision metallic parts with wide testing range from soft to hard & their accurate results are widely acclaimed. These testers strictly conform to 15:1754-1968.

FEATURES

  • Tiny indentation allows testing of a precision finished parts.
  • Thin sheet metal are perfectly tested. Because applied load is very small.
  • Motorised loading and unloading cycle.
  • Built-in projection screen to get accurate results.
  • Same hardness number is obtained on the same specimen, regardless of the load applied.
  • Wide testing range, from soft metal such as lead, upto the hardest, like hardened steel.

CONSTRUCTION

To accommodate the high precision loading system & an optical projection screen, the machine frame is designed sturdy. Specimen is placed on a testing table. The test cycle is fully automatic. The accurate load is applied on a diamond penetrator 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 measured by means of the micrometer screw of the projection screen.
