Circular saw blade in detail

Visits:Dates:2016-8-19 13:38:38

Overview,

Circular saw blade is made of metal material, because this often call for metal circular saw blade, the production process need to join the special materials, such as parts of the cutting tools are ceramics, high speed steel, tungsten carbide, titanium carbide, etc.

Second, the application of equipment

Apply to all kinds of metal cutting processing equipment, such as: circular saw machine, cutting machine, aluminum cutting machine, cutting machine, etc.

The type, the three

Circular saw blade is divided into many types according to the terms to roughly: hard alloy saw blade, HSS saw blade, saw blade milling cutter, cold saw, stainless steel blade etc.

Four, the cutting material

Low hardness of carbon steel and nonferrous metal bar and tube and so on all kinds of metal materials such as: conventional iron and steel (ultrathin steel, stainless steel, special steel, etc.), aluminum (aluminum forgings, aluminum Angle of von berg systeme, aluminum plate, aluminum and aluminum fence), wood (used to cut any size and shape of wood), stone, etc.

Five, the detailed introduction

Circular saw blade main material: high speed steel saw blade, HSS saw blade), solid carbide saw blade, carbide saw blade, insert alloy saw blade, diamond saw blade, etc; General surface coatings are: white metal saw blade (grey), saw blades (black), plating titanium nitride saw blades (gold), chromium nitride (color), etc.

The choice of substrate

___________ 65 mn spring steel good elasticity and plasticity, material economy, good hardenability of heat treatment, the heating temperature is low, easy to deformation can be used for cutting requirements is not high of the saw blade.

This carbon tool steel containing high carbon high thermal conductivity, but the temperature of 200 ℃ to 250 ℃ when the sharp decline in its hardness and wear resistance, heat treatment deformation is big, poor hardenability, tempering time easy to crack. For cutting tool manufacturing economy materials such as T8A, T10A, T12A, etc.

Pictures of alloy tool steel compared with carbon tool steel, heat resistance, good wear resistance, good processing performance, thermal deformation temperature at 300 ℃ to 400 ℃ is suitable for manufacturing high-grade alloy circular saw blade.

_____ the high-speed tool steel has good hardenability, hardness and strong rigidity, less heat deformation, ultra high strength steel, the stability of thermoplastic is suitable for manufacturing high-grade ultra-thin saw blade.

Diameter and the diameter of the choice of the saw blade is used for cutting equipment, and cutting the thickness of the workpiece.

Saw blade small diameter, cutting speed is relatively low; Saw blade diameter of saw blade and cutting equipment requirement is high, at the same time cutting efficiency is high. Circular saw machine model of the saw blade diameter according to the different use of saw blade diameter.

Standard diameter: 110 mm (4 inches), 150 mm (6 inches), 180 mm (7 inches), 200 mm (8 inches), 230 mm (9 inches), 250 mm (10 inches), 300 mm (12 inches), 350 mm (14 inches), 400 mm (16 inches), 450 mm (18 inches), 500 mm (20 inches), saw more than at the bottom of the tank saw blade precision design of 120 mm.

Teeth of the choice of serrated teeth, generally speaking, the more the number of cutting edge in unit time, the more the better cutting performance, cutting teeth but need more carbide quantity, the price of the saw blade is high, but saw a cipher, tooth chip capacitors between the quantity is small, easy to cause blade fever; Also saw too much, when feeding with improper words, each tooth cutting quantity are very few, will sharpen the edge with workpiece friction, affect the service life of blade. Usually insert spacing in 15 to 25 mm, should choose the number of teeth on the reasonable according to cutting material.

The choice of the thickness of the thinner the thickness of the saw blade is theoretically we hope saw blade, the better, kerf is actually a kind of consumption. Alloy saw blades matrix materials and manufacturing process determines the thickness of the saw blade saw blade, the thickness of a thin, saw blades work easy to shake, influence the effect of cutting. When selecting the thickness of the saw blade saw blade work should be stable and the cutting material to consider. Some special purpose also specific the thickness of the material requirements, should be used according to the requirements of equipment such as slotted saw blade, crossed blades, etc.

Tooth shape choice about commonly used tooth have tooth (teeth) alternately, flat, ladder flat tooth (high and low gear), inverted trapezoidal tooth (taper teeth), dovetail tooth (hump teeth), and does not see more of industrial-grade about three left right, left and right sides, flat teeth, etc.
