R(D)-45A1型表面洛氏硬度計(jì)是一種輕負(fù)荷洛氏硬度試驗(yàn)儀器。施加試驗(yàn)力的速度由緩沖器來調(diào)節(jié),試驗(yàn)力的變 |
換采用變荷手輪的旋轉(zhuǎn)而獲得,所以該機(jī)具有操作簡便、性能穩(wěn)定、測試速度快、試驗(yàn)力小、留下微小的壓痕等特點(diǎn), |
在大多數(shù)情況下不影響試件的使用。 |
該硬度計(jì)適用硬質(zhì)合金、滲碳鋼、淬火鋼、硬鑄鐵及軟鋼、鋁合金、銅合金和可鍛鑄鐵的硬度的測定。 |
R(D)-45A1 the surface Rockwell hardness is a light load Rockwell hardness test equipment. |
Test force imposed by the speed of the buffer to adjust, the test force of the transformation |
could be changed by the hand wheel getting,so the hardness tester is simple, stable performance, |
the test speed of the fast, the test force of the small, leaving tiny indentation,other |
characteristics, in most cases do not affect the use of samples. |
That degree of hardness accounts to be applicable to the black metalshave the rockwell |
surname degree of hardness measurement of the color metals.It is extensive to be applocable to |
factory car with calculate the section. |
