Classification and attributes of rotary files

Carbide Burrs are also called milling cutter tungsten steel grinding head. Carbide rotary file is widely used in machinery, automobile, shipping, chemical industry, craft carving and other industrial sectors, with remarkable effect. Its main uses are:

(1) Finishing various metal mold cavities, such as shoe molds, etc.

(2) Craft carving of various metals and nonmetals, carving of craft gifts.

(3) Clean the flash, burr and weld of cast, forged and welded parts, such as machine casting factory, shipyard and automobile factory.

(4) Machining chamfers and grooves of various mechanical parts, cleaning pipelines, and finishing the inner hole surfaces of mechanical parts, such as machinery factories and repair shops.

(5) Finishing of runner parts of blades, such as automobile engine factory.

Like the properties of grinding head, this paper also divides rotary files into single rotary file and rotary file set, with the following properties:

Carbide Burrs Single Rotary File

Style appearance: Single Cut pattern, Double Cut pattern, Chipbreaker Cut pattern, Diamond Cut: diamond pattern, Aluma Cut pattern, Other others

Shape: Ball sphere, Cone cone, Cone-Ball Nosed cone dome, Countersink 60° 60 cone, Countersink 90° 90° cone, Cylinder, Cylinder-Ball nosed cylindrical ball head, Flame torch shape, Flat-top Cone conical flat head, Inverted Cone inverted cone, Oval oval oval, Tree tree, Tree-Ball Nosed tree-round head, Other other Head Diameter rotary file diameters: common diameters of 3mm-25mm are collected; Shank Diameter shank diameter: the common shank diameters of 2.5mm-10mm are collected; Carbide Burrs Sets rotary file set

Number of Pieces: 4-100 common pieces are collected. Style appearance: the same as a single rotary file, but users can make multiple choices.

Use of carbide rotary file:

Alloy grinding head is a general name for a small grinding tool with handle, which is used in electric grinder, hanging grinder and hand electric drill.

The material is alloy, which is a kind of material with metal characteristics composed of two or more kinds of metals or nonmetals. Generally, it is obtained by melting into uniform liquid and solidifying. According to the number of constituent elements, it can be divided into binary alloy, ternary alloy and multicomponent alloy. China is one of the earliest countries in the world to research and produce alloys. Bronze (copper-tin alloy) technology was very developed in the Shang Dynasty (more than 3,000 years ago). Around the 6th century BC (late Spring and Autumn Period), sharp swords (steel products) were forged (and overheated).

All types of alloy grinding heads have the following generality:

(1) the melting point of most alloys is lower than that of any constituent metal in its components;

(2) the hardness is higher than that of any metal in its components;

(3) The electrical and thermal conductivity of the alloy is lower than that of any component metal. Using this characteristic of alloy, materials with high resistance and high heat resistance can be made. Materials with special properties can also be made, such as adding 15% chromium and 9% nickel into iron to obtain a corrosion-resistant stainless steel, which is suitable for chemical industry.

(4) Some have strong corrosion resistance.
