Description
The NM61 Knife Sharpening Machine is available for sale from NorMar – a purpose-built machine designed for resharpening circular knives used in fish and meat processing equipment. Whether you need to restore a slightly dull knife or bring an extremely worn blade back to exact chamfer specifications, the NM61 handles both tasks with precision.
For any fish processing facility, keeping knives sharp is not optional – it directly affects cut quality, yield, and the lifespan of your blades. The NM61 is the reliable, purpose-built solution that keeps your production running at full efficiency without the cost of frequent knife replacement.
Two things set the NM61 apart from conventional sharpening equipment. First, it uses the lapping method – a precision sharpening technique that removes only the minimum amount of material necessary, protecting the steel structure of the knife and eliminating heat buildup that would otherwise compromise blade hardness. The result is a burr-free, razor-sharp edge with a considerably extended service life compared to conventionally ground knives. Second, the NM61 covers an exceptionally wide range of knife diameters – from 200 to 400 mm as standard, and down to 90 mm with an optional attachment tool. This makes it suitable not only for Baader equipment but for circular knives from a wide range of manufacturers, meaning a single machine can serve virtually your entire fleet of processing equipment regardless of brand.
Functional Details, Technology and Advantages of NM61 knife sharpening machine
The NM61 is designed for both routine resharpening and full chamfer restoration on heavily worn blades, making it suitable for daily maintenance as well as periodic overhaul of neglected knives. The lapping method it employs works by bringing two precision wheels into contact with the knife surface at a controlled angle, ensuring consistent chamfer geometry on every pass – whether you require a unilateral or symmetrical double-sided chamfer.
Because the knife is motor-driven during the sharpening process, the operator does not need to supervise the cycle once the setup is complete. This reduces operator fatigue and ensures repeatable results regardless of who is running the machine. The sharpening wheels can be adjusted to compensate for wear, maintaining the correct angle throughout the machine’s service life.
The NM61 is also particularly well suited as a companion machine to filleting equipment such as the Baader 581, where sharp knives are a prerequisite for achieving the required cut quality and yield. Its broad compatibility across knife sizes and brands makes it a practical and cost-effective investment for any processing facility looking to reduce knife-related downtime and replacement costs.
