The Finetech Engineering Notch Cutter is a motorized notch cutter India broaching machine designed for one critical purpose: cutting precise V-notches and U-notches into plastic specimens before Izod and Charpy impact testing. As a dedicated notch cutter manufacturer India, we know that the quality of the notch directly determines the validity of the impact test result. A notch that is too deep, too shallow, has the wrong angle, or has an incorrect tip radius will produce unreliable data and fail audits.
Impact testing standards – ASTM D256 notch cutter manufacturer spec (Izod), ASTM D6110 (Charpy), ISO 179 180 notch cutter India – specify exact notch geometry: a 45 deg included angle with a tip radius of 0.25mm +/-0.05mm. The Finetech notch cutter for Izod Charpy test is engineered to produce notches meeting these dimensions consistently, specimen after specimen, with no operator variability.
As a specialist notch cutting machine for plastic testing manufacturer and specimen notching machine manufacturer, Finetech’s motorised broaching action removes material in controlled cuts rather than scraping or milling. This ensures no residual stresses, micro-cracks, or heat are introduced into the specimen – any of which would artificially affect the measured impact strength. The V notch cutter for impact testing India achieves a clean, stress-free notch profile that satisfies the most stringent quality requirements.
The V-notch is not arbitrary. It serves a precise mechanical function: creating a controlled stress concentration that forces the specimen to fracture at a known point. Without the notch, the impact energy would be distributed across the entire specimen. With a precisely cut notch from the Finetech V notch cutter for impact testing India, the test primarily measures the material’s resistance to crack propagation – the property that matters for real-world durability.
| Notch Defect | Effect on Impact Test | Root Cause |
| Tip radius too large (blunt notch) | Artificially high impact values — specimen appears tougher than it is | Worn cutter blade or wrong blade geometry |
| Tip radius too small (over-sharp) | Artificially low impact values — premature brittle fracture | Improper blade, or manual cutting with a razor/saw |
| Wrong notch angle (not 45°) | Non-standard stress field — results not comparable to standard data | Wrong cutter blade or uncalibrated machine |
| Notch too deep | Reduced remaining ligament — lower impact values | Depth stop not set correctly |
| Notch too shallow | Specimen may not break cleanly — invalid test | Depth stop not set correctly |
| Heat damage at notch tip | Altered polymer structure — unreliable results | Manual sawing, milling at high speed, or wrong technique |
| Stress whitening at notch | Pre-existing micro-damage — low impact values | Blunt blade or excessive cutting force |
Notch Type | Geometry | Standard | Application |
V-Notch (Type A) | 45 deg included angle, 0.25mm +/-0.05mm tip radius | ASTM D256 notch cutter manufacturer spec, ASTM D6110, ISO 179 180 notch cutter India | Standard notch for most notch cutter for Izod Charpy test applications |
U-Notch | 1.0mm radius semicircular notch | ISO 179-1/eU | For materials where V-notch produces too brittle a failure, or when specified by product standard |
Custom Notch | As specified by customer standard | Custom | Non-standard notch geometries – your specimen notching machine manufacturer for special testing |
