去参观了位于安徽蚌埠的生产工厂，虽然只有几十人但是产品的加工、制作、出厂检查等各个方便非常好，针对每个力值都会进行校准测验，每台产品都经过MSA测试，所有的试验力误差都在正负1%，重复性在4%以内，每台机器出厂前都会进行震荡检测，释放产品应力，防止运输途中造成测量不准确等，还可配置出口木箱，方便外贸销售

这款显微硬度计适配性与精度很亮眼，0.01~10kgf 试验力范围能覆盖 5μm TiN 镀层到淬火钢基体的检测，小力值下压痕深度精准控制在 0.5μm 内，完全避开基材干扰；自动压痕识别 + 数据导出功能很实用，批量测薄铜箔时单样检测时间从 5 分钟缩到 1.5 分钟，误差还能稳定在 ±1.5%。标配的多规格夹具能直接固定 0.1mm 薄片和小直径圆柱件，不用额外适配，日常校准也简单，用标准块调一次能稳 6 个月，工业质检和实验室小批量测试都够用，性价比挺高。

“The 0.01-1kgf force range allows precise control of indentation depth, avoiding substrate interference), and the automatic indentation measurement function reduces human error to less than 2%. The software’s ability to export hardness gradient curves is particularly useful for analyzing coating-substrate bonding. Calibration with standard blocks (HV 500/800) shows long-term stability, with deviation within 3%. “

“This cutter has been critical for our aluminum alloy and brass metallographic sample preparation. The resin-bonded SiC blades (120/180 grit) cut through 20mm-thick samples without visible thermal damage—post-cut surfaces show no oxidation (verified by optical microscopy) and require only 10 minutes of rough grinding (vs. 30 minutes with our old cutter). “

“Our lab processes 50+ steel and cast iron samples weekly, and this dual-head polishing machine has doubled our efficiency. The 900rpm/1500rpm speed settings match different stages: 900rpm with 9μm diamond paste for rough polishing (achieves Ra 0.2μm in 5 minutes) and 1500rpm with 1μm colloidal silica for final polishing (Ra ≤0.02μm, perfect for grain boundary observation).”

“We use this tester for batch inspection of quenched steel bearings (HRC 58-62) and annealed copper alloys (HRB 60-85), and its reliability is impressive. The depth-sensing system ensures accurate results even for samples with slight surface unevenness (Ra ≤1.6μm). We tested 100 bearings daily for a month, and the repeatability (RSD) is within 1.5%.”
