3 Grinding and Cut-Off Wheels Material, Power Tools, /Task Three steps to select the correct tool Material Power tool /task Tool In order to ensure the most cost-efficient use of grinding and cut-off wheels for hand-held power tools, it is necessary to select the right tool for the individual application. In our application recommendations for grinding and cut-off wheels we have taken into account the power output (watts) of the most common angle grinders in relation to the material and machining task at hand. This distinction is reflected in the following table. Steel and steel castings Material groups Non-hardened, non-heat treated steels up to 1200 N/mm² (< 35 HRC) Hardened, heat-treated steels over 1200 N/mm² (> 35 HRC) Constructional steels Carbon steels Tool steels Tool steels Tempering steels Non-alloyed steels Case-hardened steels Steel castings Alloyed steels Steel castings INOX Stainless steels Austenitic and ferritic high-grade steels Non-ferrous metals Soft non-ferrous metals Hard non-ferrous metals Aluminium alloys Brass Bronze Copper Zinc Wood/Plastics Fibre-reinforced plastics (FRP) Thermoplastics Power tools Output levels Air-powered / turbine High frequency Low power Disc dia. mm ø 100 ø 115 ø 125 ø 178 ø 230 Type of machine Power output watts Watts Watts Watts Watts Watts Air powered, speed-controlled < 1,000 < 2,000 < 4,500 < 4,500 High frequency (300 cycles) < 1,700 < 3,700 < 3,700 Air powered < 800 < 1,000 < 1,900 < 2,200 Electric, speed-controlled < 1,400 < 1,500 < 2,500 < 2,800 Electric < 700 < 1,000 < 1,200 < 2,200 < 2,500 Air powered < 400 < 600 < 800 < 1,500 < 1,800 Electric < 500 < 700 < 900 < 1,800 < 2,000 Should the machine watts output be in doubt we recommend that you focus on output level Low power.

33 Cut-Off Wheels 33

34 Cut-Off Wheels Demands on the Modern Cut-Off Wheels Thin cut-off wheels: fast, aggressive and convenient The PFERD range of thin abrasive cut-off wheels responds to today s application trends and has been universally acclaimed. Unsurpassed stock removal, operator friendly manual control, straight cuts without wheel runout, and minimum burr formation are the hallmarks of these 0.8, 1.0 and 1.6 mm wide wheels. Apart from their impressive technical features, these PFERD products are noted for their outstanding cost-effectiveness and productivity, specifically in cutting thin sheet metal and thin-walled sections. Cut-off wheels for use on stainless steel The importance of INOX materials is continually growing due to their special material properties. In cutting sheet metal and sectional products, high loads and excessive heat input must be avoided to prevent thermal distortion and subsequent corrosion problems. PFERD cut-off wheels for use on stainless steel meet these requirements perfectly through their permanent free-cutting action and minimum friction in the kerf. Similar benefits are obtained with these tools on tough and hard aluminium. Cut-off wheels for difficult applications Abrasive cut-off wheels are often used under difficult conditions. They must provide high lateral stability and stiffness, whether during removal of risers and sprues in the foundry or in performing deep cuts in solid or sectional material. PFERD cut-off wheels offer superior strength and come in widths up to 3.2 mm for maximum load and fracture resistance. Operating safety can be enhanced by using large mounting flanges (76 mm dia., see page 50), specifically when working with air turbine grinders and powerful high-frequency machines. 34

56 Diamond Cut-Off Wheels Notes, Detailed Recommendations for Use Recommendations for use 1. Always observe the directional arrow shown on each PFERD cut-off blade. 2. Never work without a protective machine hood. 3. Wear protective glasses. 4. Keep workpiece adequately supported throughout the cutting process. 5. Do not apply pressure when cutting; the machine weight provides sufficient advance. Do not tilt the rotating blade. 6. Avoid overheating. Allow blade to cool down by running the machine in idle mode. 7. Cut deeply. Always try to cut through the entire workpiece depth with a single cut. Move blade gently up and down while cutting (oscillation). PFERD diamond cut-off blades are used dry. When working on especially tough materials such as concrete with high gravel content (exposed aggregate type), the cutting blade is liable to overheat. This condition is clearly indicated by rotating sparks appearing around the circumference of the blade (see picture). To prevent damage to the blade, stop cutting at once when this effect occurs! Allow blade to cool down in idle mode for a brief period. If the sparks recur afterwards, resharpen the blade segments using our PFERD sharpening block (see page 55).

67 Cut-Off Wheels for Stationary Machines Tools Made to Customer Requirements Tools made to customer requirements PFERD support and customer service Hot cutting For particular tasks and applications (customized drive systems and material), we can supply special wheel types made to order. We provide individual and efficient advice for our customers, and if necessary, we even design special tools for the specified application. The following cut-off wheel diameters (mm) and wheel types (T, PT, CT) can be manufactured with different thicknesses and centre hole diameters upon request: Cut-off wheel diameters (mm) 700, 800, 870, 1000, 1250 Maximum operating speeds Cut-off wheels are available for max. operating speeds of 100 or 80 m/s. They meet the safety requirements of the respective professional association and the EN standard. The large number of cutting problems requires detailed advice. PFERD provides this service upon request, free of charge and without any obligation on the part of the customer. Our advice does not only extend to the selection of the right PFERD cut-off wheel, but also addresses equipment improvement aspects, e. g. with relation to extractor systems, workpiece feeding devices, clamping, etc. Our Technical Customer Support (TKB) engineers and applications research departments possess many years of experience allowing us to provide expert advice at short notice, whatever your cutting problem may be. Owing to the good relations between our development departments and many domestic and international manufacturers of abrasive cut-off machines we can also assist in the procurement of appropriate equipment. Hot cutting at workpiece temperatures up to 1000 C has become an increasingly widespread technique. Benefits: Burr-free and fast cutting of red hot billets and bars, conventional castings and continuously cast products. Abrasive cut-off machine Apart from the selection of the right tool, a sophisticated cut-off machine is the key to any economically efficient cut-off process. The following requirements must be met by any advanced cut-off machine: Chop stroke Horizontal Adequate motor power and positive power transmission from drive to spindle. The required power input depends on the wheel diameter and on the cross-section of the material to be cut. Appropriate feed rates permitting efficient cutting of cold material at 10 cm²/s and of red-hot material at up to 20 cm²/s. Suitable workpiece and wheel clamping systems.
