Kinfe Making Machine For Butcher Knife -August 2024
A butcher knife is a professional knife used for dividing and cutting a variety of animals, such as cattle, sheep, pigs and other animals. The raw material is generally 40Cr13, and the better one is X50CrMoV15 (that is, German standard 1.4116).
Slicing knife: Slicing knife have long, thin blades with either a pointed or rounded end and are useful for slicing meats, vegetables, and other foods to make even, thin cuts.
Boning knife: Refers to a knife used to cut tendons, bones and cartilage during slaughtering. It has a short blade and a hard texture.
Skinning knife: This knife used to separate hide and meat from animals during slaughter.
Cleaver: Cleaver is a knife specifically designed to handle large pieces of meat and bone. Generally, the blade is curved, with thick back and thin blade.
Utility knife: Utility knife is a very practical daily knife, sharp, smooth blade, suitable for peeling, cutting vegetables and fine slicing.
Making butcher knife mainly includes raw material processing, pneumatic punching machine for forming, flattening machine for flattening, steel strip heat treatment furnace for quenching and annealing, CNC single-side grinding machine for grinding, single-side polishing machine for polishing, auto cleaning machine for ultrasonic cleaning, quality checking to test sharpness and hardness, packaging and other links. The whole processes adopt automatic control, and each step is strictly controlled.
Knife Blanking Machine: First of all, the raw material needs to be processed to make it into a rough shape of the butcher knife we need. The the automated feeder accurately feeds the sheet into the mold, and after repeated punching, then get the rough shape of butcher knife. The whole process is efficient and precise, greatly improving production efficiency and product quality.
Knife Flattening Machine: After forming, the formed material is flatted with an automatic flattening machine. Can get a good flattening effect.
Knife Making Mahcine For Heat Treatment: Use steel strip heat treatment furnace quenching and annealing of formed and Flatted material, make sure the knife is flat after quenching, and the temperature is about 980-1060° C. Then tempering 150-300° c, improve toughness. After heat treatment, the general hardness reaches HRC 56~58. Hardness will decrease HRC 2~3 after water grinding.
knife Back edge grinding machine: We will grind the blade that has taken initial shape, first grind the back of the blade, remove the back of butcher knife and let it become more smooth. Remove burrs and particle impurities on the back of the knife. During the grinding process, automated equipment can efficiently complete the grinding and achieve good results.
knife Surface grinding machine: After back edge grinding of butcher knife, and then grind the flat surface of the blade to get the initial effect, and remove the surface burrs and rough impurities. After a few grinding processes, the surface of the knife will look like a mirror.
Knife Edge sharpening grinding machine: Using the edge sharpening grinder to sharpens the cutting edge of the knife, and the cutting edge produced by the machine is particularly sharp. Make the blade sharper, and the butcher knife can be put into use only after this step.
Injection: Most of butcher knives are used plastic handles, non-slip and cost-effective. So we often use the plastic injection molding machine.Makes thermoplastics or thermoset plastics into plastic products of various shapes by plastic molding die. The injection molding machine heats the plastic and applies high pressure to the molten plastic, causing it to shoot out and fill the mold cavity.
Handle polishing Machine: Using the CNC abrasive belt polishing machine to polish the handles, and polish the defects and weld lines on the handle surface caused by injection molding to achieve a smooth state, which is convenient for gripping and more comfortable and durable
The cleaning process is mainly to remove the oil and impurities on the surface of the butcher knife to ensure the hygiene and cleanliness of the knife before leaving the factory. Our ultrasonic cleaning line can complete this task efficiently and thoroughly, preparing for the final packaging process
Industrial slaughterhouses generally use plastic handles, large amount of knives, non-slip and cost-effective. Butcher knife include Slicing knife, Boning knife/ Fillet knife, Cleaver, Utility knife, Skinning knife. The most famous brands of butcher knives are Victorinox in Switzerland, Friedr Dick in Germany, Formosa recommended in China.
