What factors should be considered when selecting the right carbide threading ins

4Here are some common problems and solutions of carbide insert machining.No.1 Wear on Clearance FaceFast wear on Clearance face results in poor surface qualityWays to improve:1. Reduce cutting speed2.Gradually increase feed3.Use inserts with better wear resistant material or coating4.Increase cooling fluid supply5.Clockwise millingNo.2 Crater Wear on rake faceExcessive crater wear reduces strength of cutting edgeWays to improve:1.Reduce cutting speed2.Reduce feed3.Use inserts with positive rake angle,more duranle material or cotaing.4.Avoid built-up egdeNo.3 Cutting Edge DamageSmall breakage of the cutting edge results in poor surface quality and excessive flank wearWays to improve:1. Cutting edge been cracked,then to increase cutting Face Milling Inserts speed2. Eliminate vibration factors3. Uneven workpiece material,then to reduce cutting speed and increase feed,Clockwise milling.4. Whether insert body is annealed, the shim is broken, or the blade screw needs to be replaced.5. Use higher strength inserts material6. Change inserts with strong edge7. Chilled cast iron workpiece requires negative rake angle inserts8. Milling tools with round inserts are with best impact resistanceNo.4 Plastic DeformationThe cutting edge collapses or clearance face recessed, resulting in poor cutting control and surface quality. The flank wear would cause inserts breakage.Ways to improve:1. Choose a harder grade with higher resistance to plastic deformation2. Cutting edge collapses: Reduce cutting speed3. Clearance face recessed: reduce feedNo.5 Built-up EdgeBuilt -up edge results in poor surface Machining Carbide Inserts quality,when falling down,it would cause breakage of cutting egdeWays to improve:1. Increase cutting speed2. Gradually increase feed to the optimum chip breaking thickness3. Use CVD Coating Inserts4. Adequate high pressure coolant fluid or air to prevent secondary chip breaking5. Clockwise milling6. Positive rake agnle tool and insertsRelated search keywords:carbide inserts, carbide inserts for wood, carbide inserts code, carbide inserts manufacturers, carbide inserts size chart, carbide inserts for aluminium, carbide inserts angles, carbide inserts apkt, carbide inserts for aluminum, carbide inserts brazed, carbide inserts brazing, carbide inserts bits, carbide inserts end mills, carbide inserts for lathe tools, carbide inserts grade, carbide inserts holders, carbide inserts lathe, carbide lathe cutter inserts, wood lathe carbide inserts, carbide inserts material, round carbide inserts, negative rake carbide inserts, carbide inserts turning tool, carbide inserts tool holders
