Case Study: ZANHO WNMG080412-TM TC20P Achieves 31% Higher Tool Life in 55# Steel Turning
Looking for a cost-effective alternative to premium steel turning inserts? See how ZANHO TC20P outperformed a leading competitor in high-speed machining.
1. Challenge & Test Objective
The objective was to evaluate the performance of the ZANHO WNMG080412-TM TC20P against a premium competitor's HS8125 equivalent. The test focused on durability and cutting stability when machining 55# medium carbon steel under identical conditions.
2. Machining Conditions
Precision is key in turning operations. Below are the parameters used during this comparative cutting test:
| Parameter | Details |
|---|---|
| Workpiece Material | 55# Steel (Medium Carbon Steel) |
| Insert Type | WNMG080412-TM |
| Cutting Speed (Vc) | 570–1060 m/min |
| Feed Rate (fn) | 0.25 mm/rev |
| Depth of Cut (ap) | 1.2 mm |
| Coolant | Water-soluble Emulsion |
3. Tool Life Comparison Results
The ZANHO WNMG080412-TM TC20P showed significantly higher consistency compared to the competitor's grade, which suffered from premature wear on its second edge.
| Insert Grade | Edge 1 (pcs) | Edge 2 (pcs) | Edge 3 (pcs) | Average Life |
|---|---|---|---|---|
| ZANHO TC20P | 40 | 43 | 36 | 39.7 pcs |
| Competitor HS8125 | 36 | 19 | 36 | 30.3 pcs |
Performance Gain: +31% Tool Life Improvement
