An example of a significant contribution to higher sustainability are the grinding robots E 50 R and E 50 RT: Hand knives ground with the E 50 robot technology allow more precise cuts. This increases the meat yield by up to 0.5% compared to hand grinding. With 10,000 tons of meat production, this is 50,000 kg more yield.In addition, knives sharpened with robot technology reduce the risk of accidents, and reduce losses due to inflammation in the arm and shoulder, known as MSD and RSI diseases, by up to 80% (source: Anago Ltd.).

The EVO 5 is a new development with the main focus on hand knives. It produces precise and super sharp grindings. The machine is extremely easy to operate. The knife guides ensure that the hand knives are always ground with the correct cutting edge angle. Integrated magnets support the guiding of the knife and make the sharpening process highly simple.

The grinding angle is infinitely adjustable. Thus, the optimum cutting edge angle is available for every application.

The polishing disk produces fine, polished surfaces and a burr-free, very smooth cutting edge. The precisely set peripheral speed and the optimally balanced polishing disk resistance compensate for handling errors.

Health protection is a high priority for the EVO 5. The integrated coolant device binds the grinding abrasion and prevents it from escaping into the environment. This protects the operator's breathing passages. A dirt-resistant membrane pump conveys the cooling water to the grinding unit. The cutting edges cannot be overheated during grinding. The grinding abrasion collects in the water tray. A magnetic bar separates the dirty area from the clean area. This prevents the grinding abrasion from re-entering the coolant circuit.

In addition to water cooling, the EVO 5 offers optional polishing dust extraction. A standard industrial vacuum cleaner can be connected to the machine's suction socket. The operator's breathing passages are thus protected as effectively as possible.

With the K24 system, KNECHT above all revolutionised the construction and holding unit of knives in order to make handling as easy and safe as possible. It is less vulnerable to corrosion and abrasion. Three knife shapes for boiled sausage, dry sausage and sausage meat are available for the K24 cutter knife system.

• no movable parts such as bolts or screws
• instead of expensive retaining rings, K 24 system uses a combination of a toothed profile sleeve
• and simple intermediate rings
• simplified handling and increased safety in operation of the cutting system
• considerable increased security against fracture: steel no longer touches steel on the clamping area of the knives
• ideally coordinated components
• reduced operating cost
• standardized production: the K 24 cutterknife system can be used on any bowl cutter

The A 95 grinds sickle-shaped knives and circular knives of all brands up to 1200 mm (47.2 in). The machine is simple and easy to operate via touch panel. It provides highest ­grinding precision and best repeat accuracy.

Furthermore, the A 95 is optimally qualified for initial-serration and re-serration of slicer knives. Once the knives are serrated first-time on the A 95, the machine will always be able to pick up the correct starting point in the existing serration. A wide variety of different tooth shapes (e.g. pointed, hollow or wavelike) are saved in the memory and can easily be recalled.

The B 600 sharpens, polishes and deburrs cutter knives up to a size of 1000 l fully automatically. The knife changer picks up the knife from the magazine and moves it to the grinding position. The sharpening program is started. After the grinding process is finished, the knife is returned to the magazine and the next knife is picked up. The machine processes up to 16 cutter knives in unmanned operation.

The performance amounts up to 80 cutter knives (500-750 l) per 8-hour shift. With each regrinding the complete blade profile is processed. The average process time per knife runs from 3 to 5 minutes, depending on the blade size. There is very little material removal from the knife. A 500 l cutter knife can be reground up to 40 times.
