About safety when using cutting tool products 1. When using cutting tool products 1 In accordance with the Product Liability Law (PL law) enforced on July 1, 1995, our company has attached warning labels and caution labels to the packaging of our applicable products. However, there are no specific caution notes, etc. displayed on the tools themselves. Before handling or using any cutting tool or cutting tool material, please read the sections "About safety when using cutting tool products" and "Cautions regarding the use of cutting tools" in this catalog. In addition, please teach the information stated in these sections to all workers as part of the safety education at your company. 2. Basic characteristics of cutting tool materials Meanings of words used in this catalog Cutting tool materials: General terms such as carbide alloy, cermet, ceramics, sintered CBN, sintered diamond, HSS, alloy steel, etc. Physical characteristics Appearance: Varies depending on material properties and material type. Example: Gray, black, gold, etc. Odor Odorless Hardness Carbide alloy, cermet: 5 to 30GPaHV; Ceramic: 10 to 40GPaHV; Sintered CBN: 20 to 50GPaHV; Sintered diamond: 80 to 120GPaHV; HSS: 2 to 12GPaHV; Alloy steel: 2 to 12GPaHV Specific gravity: Carbide alloy: 9 to 16; Cermet: 5 to 9; Ceramic: 2 to 7; Sintered CBN: 3 to 5; Sintered diamond: 3 to 5; HSS: 7 to 9; Alloy steel: 7 to 9 Composition Including carbides, nitrides, and sulfides of W, Ti, Al, Si, Ta, Nb, B, V, etc. as well as metal components of Fe, Co, Ni, Cr, Mo, etc. 3. Cautions regarding the handling of cutting tool mate O Cutting tool materials have the characteristics of being extremely hard yet brittle. Therefore, they may be broken by impact or by overtightening. O Since carbide tool materials have high specific gravities, be careful to handle large products or large quantities as heavy materials. O The thermal expansion of carbide tool materials is different from that of metal materials. Because of this, for shrink-fit or cooling-fit products, if the usage temperature is slightly higher (lower) than the specified temperature, cracking may occur. O If cutting tool materials become corroded due to cutting fluid, lubricating agents, or other moisture, their strength will be reduced. Care should be taken regarding storage conditions. 4. Cautions regarding machining of cutting tool products (materials) O For carbide tool materials, the strength may be slightly reduced due to the surface conditions. For finishing, always use a diamond grinder. O When cutting tool materials are ground or heated, dust or mist (smoke) occurs. If a lot of it is inhaled, swallowed, or comes in contact with the eyes or skin, it could result in injury to the body. When machining, be careful to avoid exposing your body to the dust or mist; it is recommended that localized ventilation equipment be used and that a protective mask, protective goggles, and protective gloves be worn. In addition, if the dust, etc. comes in contact with your hands, wash them thoroughly with soap and water. Do not drink or eat in the work area, and wash your hands before drinking or eating. Dust on clothes should not be shaken out; use a vacuum, etc. to remove the dust or wash the clothes in a washing machine. If the cobalt contained in the cutting tool material is touched repeatedly or over a long period of time, it has been reported that it may affect the skin, respiratory organs, or heart, etc. For detailed information, refer to the MSDS published by our company. MSDS = Material Safety Data Sheet (safety data sheet for chemical substances, etc.) Homepage http: www.hitachi-tool.co.Jp/e/company/environment/msds/index.html O When performing wet machining of carbide tool materials or brazed tool, the cutting fluid may contain heavy metals and must be disposed of properly. O When a cutting tool product has been reground, check that there are no cracks after regrinding. O If a laser or electric pen, etc. is used to mark carbide tool material or products, cracks may form. Do not mark sections which may be subject to stress. C75
