3) Rockwell hardness tester
洛氏硬度计
1.
Using the cone anvil made by self, inspect the hardness of small steel ball on WELSON - A653T Rockwell hardness tester ,solve the problem of the small steel ball is slip on the pedestal anvil and "V" shape anvil, difficult to fix,and make the variance analysis to the result compare with traditional method,and to prove the result , of inspect by this way is correct.
在WELSON—A653T洛氏硬度计上,采用自制凹锥形砧座测试微小钢球的硬度,解决了微小钢球在常用平面砧座和V形砧座上易打滑,不易固定,致使压头打在砧座上,损坏压头和砧座的难题,并采用方差分析的方法,将该法与传统试验方法相比较,验证其检测结果与传统法所获检验结果无显著性差异。
2.
The Rockwell hardness tester is a precision measurement instrument in material and part hardness testing, which is often used in detection of materials, product and half-finished product.
洛氏硬度计是检测材料和零件硬度较精密的计量仪器,用来测量材料或者成品半成品的相应硬度,其性能指标主要体现在检测精度和操控性两个方面。
3.
The text particular introduced working principle of Rockwell hardness tester, designed load-up program, analyzed raliability,and according related requirements elected electromechanical and the like components.
传统洛氏硬度计采用杠杆加载,压头多在侧向用紧定螺钉顶紧,长期使用很难保证精度,且需要操作人员的经验和技巧。
4) Rockwell hardness number

5) TH320 Rockwell accelerometer
TH320全洛氏硬度计
1.
Through the subsection digital adjustment, TH320 Rockwell accelerometer gets over the difficulty in adjustment experienced by common Rockwell Accelerometer due to poor demonstration linearity,thus the value indication adjustment becomes easy and convenient.
如何利用手中的有限的标准块,修正标尺整个测试范围内的数据,该文通过实际数据的测试,进一步认识了TH320全洛氏硬度计在示值误差调整方面的特点。
6) gear-wheel Rockweel tester
齿轮洛氏硬度计
补充资料：洛氏硬度
分子式：
CAS号：
性质：又称罗氏硬度。表示材料硬度。一种标准。用符号HR表示。应用压入法把压力施加在金刚钻尖上，使压入所试材料的表面而产生凹痕。用测得的凹痕深度来表示硬度。标度数越大，硬度越小。用于测定塑料、绝缘材料和金属材料等的硬度。
