1、Introduction to high-speed steel(HSS):

High-speed steel is a kind of high alloy special steel, the main alloy content of tungsten, molybdenum, chromium, vanadium, cobalt and other precious metals, it through the special heat treatment process, high temperature quenching and high temperature tempering, It can make the workpiece hardness reach HRC 63-70. It is used to make tools to cut other metal materials.High-speed steel has high hot hardness, high toughness , high wear resistance and other characteristics, so it used in the industrial area widely. Usually it used to make drills, miller, taps, HSS white knife, saws and other cutting tools.

The use and maintain of the sawblade

◎ The carbide tip of sawblade is very sharp, so process of using must be prevent the carbide tip.

◎ PeriodicaI cleaning and support the machine,the spindle’s running tolerance must be less than h7.

◎ The flanges must be parallel to each other,must be of the same diameter 1/3 of the sawblade’s diameter(formuIti—rip saw blade is 1/2.

◎ When instaIIion the sawbIade,it shaII be 5-6 teeth higher than board surface．

◎ Before operation,check the firmly of the sawblade,be sure nobody in front of the machine. Do not feed of operation check whether the machine is good for operaiton. Periodical check the function of the machine,the certicaI jump is less than ±0.02MM,and the flap is less than ±0.01.

◎ After continuous use,must be removed and cleaning the sawblade,get rid of the resin and sawdust of the sawblade of both sides.Other wise it would beinfluence the effect of using the sawblade.

◎ Deposit of the sawblade,must not be layer the sawblade,it is putted in the originaI package inside.

The renovate of the sawbIade

◎ The renovate of the carbide sawblade While it no longer sharpen and the horizontaI piece coarseaess. The power of using sawblade machine obviously Increase. When process materiaI,the materiaI appearred burst. The carbide tip exhaust more than 0.02MM.

◎ For the renovate the sawblade,it shouId be grinding by the a formal company, so be sure the quality of the sawblade after renovating.
