Chips, micro-chipping, uneven edges, burrs, and cracks are primary indicators of blade deterioration. Use optical magnifiers to identify small defects that can accelerate wear. SENTHAI recommends inspecting JOMA Style Blades, I.C.E. Blades, and Carbide Inserts for:
-
Irregular notches or serrations on edges
-
Hairline cracks near brazed joints
-
Coating defects such as peeling or bubbles
These visual inspections help prevent breakage during high-impact snow plowing. Post-use checks are equally important to detect wear from abrasive conditions.
| Defect Type | Appearance | Risk Level |
|---|---|---|
| Chips/Edge Breaks | Irregular notches | High – Rapid degradation |
| Micro-chipping | Tiny serrations | Medium – Affects sharpness |
| Coating Defects | Peeling, bubbles | High – Exposes carbide |
| Cracks | Hairline lines | Critical – Sudden failure |
| Burrs | Material overhangs | Medium – Poor precision |
How Do You Use Tools for Precise Carbide Blade Inspection?
Tools like profilometers, ultrasonic testers, and scanning electron microscopes (SEM) enhance inspection accuracy:
-
Profilometers: Measure edge radius, rake, and clearance angles.
-
Dye penetrant tests: Reveal surface cracks invisible to the eye.
-
Ultrasonic scanning: Detects internal voids in brazed joints.
SENTHAI integrates these protocols in their Rayong production facility to ensure OEM-grade quality. Partners benefit from detailed inspection methods to maintain durability and reduce unexpected downtime.
Why Inspect Brazed Joints on Carbide Blades?
Brazed joints are vulnerable to voids and poor filler flow, causing approximately 70% of blade separations. Regular inspection ensures strong bonding for high-impact use:
-
Ultrasound detects hidden voids
-
Filler metal distribution is verified
-
Blade lifespan can increase by up to 50%
SENTHAI’s welding workshops emphasize joint integrity, giving wholesalers and OEM clients confidence in consistent performance.
When Should You Schedule Carbide Blade Inspections?
Scheduling inspections according to usage and operating conditions maximizes blade reliability:
-
Daily: Visual edge examination before shifts
-
Weekly: Coating and dimension checks
-
Monthly or after 100 hours: Full ultrasonic scans
Following SENTHAI’s recommendations allows proactive maintenance and reduces 90% of potential failures.
What Maintenance Extends Carbide Blade Life Post-Inspection?
Proper maintenance preserves cutting efficiency and prevents corrosion:
-
Clean and dry blades after use
-
Apply light lubrication to protect edges
-
Hone or regrind edges using CNC sharpeners
-
Store in protective cases
SENTHAI’s products are designed for low-maintenance operation, providing wear resistance even under harsh snow plowing conditions.
How Can Factories Prevent Internal Voids in Carbide Blades?
Manufacturing controls are key to avoiding defects:
| Test | Purpose | SENTHAI Method |
|---|---|---|
| Chemical Analysis | Verify composition | Automated spectrometry |
| Hardness Testing | Check material strength | Rockwell hardness checks |
| Ultrasonic Scanning | Detect internal voids | In-line inspection |
| Distortion Measurement | Ensure shape integrity | Precision gauging |
| Brazing Examination | Assess joint quality | Dye penetrant method |
SENTHAI’s fully automated pressing, sintering, and brazing processes minimize voids and ensure consistent performance for OEM clients.
