SAFETY GUIDE OF CARBIDE PRODUCTS H 4) Check for cracks after re - grinding carbide tool and reuse. TOOTOOL TECHNOLOGY is continuously trying to develop 5 ) Marking with laser or electric pen may cause cracks on the carbide tool . The crack can safer and higher quality products Please be aware of the shortened tool life. safety guidelines below prior to using METOMET tools . 6) EDM of carbide may cause residual cracks on the carbide tool, so if necessary, remove the crack with a grinding process. •It is generally accepted that the proper handling of cemented carbide tools requires 7) Brazing of carbide tools at extremly high or low temperatures compare with the melting point awareness of safety as noted above. For more information. Please contact us. of brazing materials may cause loosening or breakage. •TOOTOOL TECHNOLOGY does not accept any responsibility for any accident caused by 8) Overheating a oil base coolant may cause a fire or flames, thus be prepared for fire inappropriate use, about of tools, or changes to the products . prevention. 1. PL ( Product Liability) 5 . METALCUTTING SAFETY In accordance with the PL ( Product Liablility ) law, we have attached a WARNING label on the case of METOMET products. There isno warning on the surface of the tools . Please read this safety guidelines before using carbide tools and provide safety education to all users. DANGEROUS FACTOR SAFETY COUNTERPLAN 2 . Basic characteristics of CEMENTED CARBIDE tools • Sharp cutting edge of cutting tools may cut your bare -hand • Use gloves when pulling out the insert from the case or mounting it on the machine • Use glasses or safety cover for safety Cemented carbide tools are made of carbides , nitrides, carbon it rides, oxides of W, Ti, Al, Si, Ta, B • Inappropriate conditions or usage may cuase fragmentation and expel parts of tools which may cause injury • Use the tools within the recommended range etc and metal component like CO, Ni, Cr, Mo as binder. Cemented carbides tools have high • Please refer to catalogue and safety guidelines first . hardness and sepcific gravity. Generally there ' s no smell but according to usage and treatment, • Severe load on tool and premature wear of cutting edge may bring excessive cutting force on tools, causing fracutre of the tool and may • Use glasses or safety cover for your safety appreance and color could be changed. cause injury • Change the tool as required before excessive wear or fracutre 3 . Precaution for CEMENTED CARBIDE tools • Chips evacuated during cutting are hot and sharp and may cause • Use glasses or safety cover for your safety 1) Cemented carbides are extremely hard and brittle at the same time . burns and cuts • Stop machining and put safety glove on and use a hook tool to remove chips Impact shock or excessive clamping power could cause fracture orbreaking of the tool. • Touching the workpiece immediately after cutting may cause burns • Use gloves or safety cover for your safety o • Be aware of sparks , fire , or explosion of hot chips generated during • Do not use at the place where having explosive materials 2 ) Cemented carbides have large specific gravity, thus they require special attention as a heavy c the cutting operation. • Prepare for fire extinguishments 003 material when you handle big size or large quantities. D CQ • In case of high RPM machining , vibration and chattering may occur • Use glasses or safety cover for your safety 004 3 ) Cemented carbides have different thermal expansion coefficient with steel and ferrous O O due to the improper balance of the machine • Check first if there ' s any chattering , vibration or strange noises prior to your main cutting operation materials. Shrink fit or swell fit products may cause trouble if they are used at undesirable C/) • Touching a burr remaining on the workpiece with a bare -hand may • Do not touch the burr with bare - hand conditions like extremly high or low temperatures. cause a cut • Use glaoves or safety cover for your safety 4) There are several cemented carbide products having sharp cutting edges. • Loose clamping of the workpiece may cause the tool to fracture and result in damage to the cutter body and possible injury • Clamp the workpiece tightly Be careful not to handle the tools with bare hands which may cause cuts or injury, especially • Tools are operated to right -hand direction normally . Left - hand • Do not use left - hand direction without notice when removing the tools from the case, do not touch the cutting edge and be careful not to direction operation can cause fracture of tool and body damage • Check the package of product to check the availability of left - hand operation drop it. • Loose clamping of inserts and parts may result in ejection of the tool during cutting and may cuase serious injury • Check the clamping of inserts and parts prior to machining , and use original parts only 5 ) Storing carbide tools in a corrosive atmosphere may cause erosion which can reduce toughness. • Over loaded clamping of inserts by a lever ( such as a pipe ) may cause dangerous fracturing of parts and inserts • Do not use lever inappropriately 6) Please refer to the catalogue safety guidance prior to handling the tools. • In case of high speed machining , parts and inserts can be forced • Use within recommended condition 7) Do not absue tools under inappropriate conditions. out by centrifugal force • Use glasses or safety cover for your safety • Since cutter has sharp cutting edges touching with a bare - hand • Use gloves or safety cover for your safety 4. Precaution for machining ( grinding, welding, EDM ) of CEMENTED may cuase a cut 7J O • It is dangerous to use glove with rotating machine • Do not wear gloves when you work with rotating machine CARBIDE tools Q) • Contact with body or clothes is dangerous with rotating parts • Keep your body and clothes away from rotating machine 1) Surface condition can affect the toughness of the tool, so it is recommended to use a CQ • Vibration generated by balancing trouble may cuase a fracture and • RPM should be controled within recommended condition diamond grinding wheel . O ejection of the tool which may cuase serious injury • Check the balance of rotating part periodically 2 ) Grinding of cemented carbide creates mist and dust . It contains harmful compositions like Co, O cn • In case of drilling , the uncut bottom core can fly out of the part with high speed and cause serious injury • Use gloves or safety cover for your safety thus it is recommended to use a mask , mist collection, and other protective facilities. If the dust • The deges of small diameter drill are sharp and easy to break • Use gloves or safety cover for your safety gets in your skin or eye, rinse immeditely with continously running water. O 3 • Check the brazed tip before using 3 ) In case of grinding with coolant, coolant contains harmful metal components which cuase O ft • Fragmentation and ejection of brazed carbide tip may cause injury environmental problems. Handle the coolant according to the manufacturer ' s (/) CD Q. • Do not use at high temperature cutting condition recommendations. m • There' s a possibility of breaking the carbide tip after several brazing • Do not use brazing a tip that has been brazed several times o • Abusing may cause fragmentation of tool and is very dangerous • Stick to safety regulations and guidelines
