Ordering replacement granulator blades sounds simple — until the new knives arrive and the bolt holes don’t line up, or the bevel faces the wrong way. A blade that is even 1–2 mm off will not seat correctly, and a wrong bevel angle tears your material instead of cutting it. This guide shows you exactly what to measure so your replacement drops in the first time.
At HK BladeTech, the fastest way to get an accurate quote is to send us your machine model or OEM part number. But when a part number isn’t available — or you simply want to verify a fit before ordering — these are the dimensions our engineers in Ma’anshan need.
Measure the longest edge of the blade, end to end, in millimetres. For rotor (fly) knives this is the cutting-edge length. Use a steel ruler or caliper and measure the steel body only — do not include mounting tabs unless they are part of the blade itself.
Measure from the cutting edge to the back (mounting) edge. This dimension shrinks every time a blade is re-sharpened, so always measure from an unworn blade or the original drawing — never from one that has already been ground down several times.
Measure the blade body thickness with a caliper. Granulator knives are commonly 10–25 mm thick. Thickness affects both strength and how the blade seats against the rotor, so accuracy matters here.
The hole pattern is the single most common reason a “correct size” blade still won’t fit. Double-check these numbers.
The bevel is the angled cutting face. Note the approximate angle (commonly 30°–60°) and — just as important — which side the bevel is on and which way it faces when installed. A left-hand and a right-hand blade can share every dimension and still be wrong if the bevel is mirrored.
Every dimension above is already fixed by your machine. If you can tell us the make and model — for example Cumberland 1012, Rapid 2036, Vecoplan, Nelmor or Weima — and whether you need rotor (fly) knives or bed (stationary) knives, we can match the correct drop-in replacement from our catalogue without you measuring anything.
Email a photo with your measurements, a drawing, or simply your machine model to our team. We’ll confirm the exact drop-in replacement and send a factory-direct quote — usually within a few hours, in clear English.
