英国一家专门制造机械试验设备的公司最近将一台做大型零件的布氏硬度试验的装置投入市场。BHD 布氏硬度试验装置有很高的精度,它配有一可加荷的试验头(根据英国有关标准加荷)和一独立的固定式工作台。加荷试验头和固定式工作台的设计避免了试验大型零件时所常常碰到的问题。试验头可以升降以做试验前的精确调节,试件被置于可承受最大重量 A British company specializing in the manufacture of mechanical test equipment recently brought a Brinell hardness test device for large parts to market. The BHD Brinell hardness test rig is highly accurate and comes with a loadable test head (based on UK standard loading) and a stand-alone stationary table. The design of the load test head and stationary work bench avoids the problems often encountered when testing large parts. The test head can be raised and lowered to make precise adjustments before the test. The test piece is placed under a maximum weight
