ROUND TOOLS 14 / NORTON WINTER PRECISION TECHNOLOGY TOOL GRINDING GENERAL INFORMATION Drills, end mills, reamers, stepped tools and special-purpose tools in varying designs and geometries are described as round tools. Tool geometries are produced by grinding in successive production steps. A typical sequence starts with the preparation of the blank, (tools for trimming blanks can be found in the section for ‘Diamond and cBN cut-off wheels’) which is followed by flute grinding, gashing and grinding of the clearance angles. The product range for round tools is extensive. Different materials and tool geometries make various demands on the grinding tools used in manufacture. Information Further information on applications and products can be found at www.nortonabrasives.com Shorter grinding times, better suitability for automation and longer dressing intervals are required. Specific grinding wheel characteristics such as edge stability and free-grinding behaviour have to be carefully balanced. ROUND TOOLS GENERAL INFORMATION FLUTE GRINDING GASH CLEARANCE ANGLE GRINDING Drill End mill Source: Gash 1. Clearance angle 1. Clearance angle 2. Clearance angle Clearance 2. Clearance angle Flute This section is structured according to the procedure described. Here you see an example of an end mill and a drill. Generally, the same tool geometries are used for the individual process steps. Only flute grinding uses different grinding wheel designs. While 1A1 and 1V1 grinding wheels are used primarily for end mills, profile grinding wheels such as 14F1 and similar (Norton Winter shape 700) are preferred for drill production.
ROUND TOOLS NORTON WINTER PRECISION TECHNOLOGY TOOL GRINDING / 15 DIAMOND & CBN GRINDING WHEELS FOR FLUTE GRINDING Flute grinding is the most time-consuming and thus most cost-intensive manufacturing step during drill and end mill production. It is necessary to optimise the machine and cooling lubricant systems as well as the abrasives. In recent years, machines have become more compact, spindle power has increased, axis paths have been reduced and machine controls have become more efficient. At the same time, Norton Winter has developed flute grinding tools which meet these increasing requirements and which now enable the improved machine capacity to deliver a higher and more economic output. Matched to the application and the system environment, innovative Norton Winter flute grinding wheels are always the best solution. Grinding wheels in the Q-Flute range have proved to be particularly useful for standard tools. The combination of excellent free-grinding behaviour and profile retention allows economic flute grinding with high feed rates. Q-Flute grinding wheels can also be dressed on the grinding machines. Mini and micro tools require bond systems with exceptional edge stability. Norton Winter metal bonds and high-performance resin bonds are the number one choice here. edge stable Clearance grinding profilable Standard tools Mini tools WHEEL WEAR (%) Low Wear Low Forces High Wear 60 50 60 70 GRINDING FORCES (%) 80 90 100 120 130 70 80 110 90 100 120 130 150 Q-Flute 2 Competition Q-Flute EVO Q-Flute XL40 140 110

HIGH-PERFORMANCE FLUTE GRINDING Q-Flute PRIME is the further development of Q-Flute EVO and the latest premium high-performance solution for flute grinding of round tools. Q-Flute PRIME is the solution for maximum increase in productivity. Compared to all previous specifications, it offers significantly better profile retention, as the grinding forces have been clearly reduced, as well as improved grinding quality (surface in the flute). Q-Flute PRIME is showing the optimum combination of free grinding behaviour & edge stability. SPECIFICATION APPLICATIONS Q-Flute PRIME Tungsten carbide, Oil and water based coolant Q-Flute EVO Tungsten carbide and HSS, Oil and water based coolant STOCK PROGRAMME Q-FLUTE EVO AND Q-FLUTE PRIME The market’s demand to have a comprehensive range of grinding tools available from stock, has grown steadily in recent years. In order to meet this market demand even better, we offer a stock programme of our current premium products Q-Flute EVO and Q-Flute PRIME. The aim is to be able to supply our customers with a much wider range of grinding wheel dimensions within the shortest possible time. Norton Winter now has various dimensions of semi-finished parts in stock. These semi-finished parts can be finished into a variety of different finished products within a very short time after receipt of order. The delivery time for all grinding wheel dimensions that can be produced from semi-finished parts is approx. 5 working days. This allows us to offer our customers maximum flexibility and the shortest possible delivery times. In addition, Norton Winter offers a 60 % increased coating depth for 1A1 grinding wheels and thus significantly more abrasive layer for the money. Due to the trend towards ever smaller batch sizes and ever more demanding requirements in the machining of round tools the performance, efficiency and flexibility of the grinding tool are becoming more and more important. In order to meet these requirements, Norton Winter has developed the Q-Flute EVO as a highly flexible and powerful evolution of the well-known Q-Flute2 and XL. Q-Flute EVO combines and improves the good features of Q-Flute² and Q-FLute XL40. This offers unique combination of free-grinding behaviour and profile stability.

ROUND TOOLS 22 / NORTON WINTER PRECISION TECHNOLOGY TOOL GRINDING DRESSING ON THE PRODUCTION MACHINE Each tool change on a grinding machine causes a degree of run-out and positional error, which can produce small deviations from the nominal tool geometry. Demands made on the accuracy of round tools, however, are constantly increasing. Norton Winter Q-Flute grinding wheels are the solution to this problem. Q-Flute technology combines innovative flute grinding with the precise touch dressing process. This innovative technology enables considerable quality improvements to the main and minor cutting edges, without adversely affecting grinding performance. By regularly regenerating the wheel topography, tighter tolerances and fully automatic shift operations are possible. AREAS OF APPLICATION Norton Winter Q-Flute grinding wheels finding their areas of application at all applications where high MRR are required.

ROUND TOOLS NORTON WINTER PRECISION TECHNOLOGY TOOL GRINDING / 23 NORTON WINTER DIAMOND DRESSING SYSTEM (DDS) The Diamond Dressing System (DDS) allows CNC dressing of diamond grinding wheels directly on production grinders. Despite the extreme hardness of diamond in both cases, the same physical correlations are found when dressing “softer“ abrasive materials such as Al2O3, SiC, SG, TG and cBN. Even when dressing specifically designed diamond grinding wheels with the DDS roller dresser, the result can be influenced by overlap rate and speed ratio. DRESSING PARAMETERS Speed ratio: qd = 0.6...0.9 Overlap rate: Ud = 2...6 Dressing infeed: aed = 1...5 µm PROFILE EXAMPLES CNC-precision dressing on the production machine - greater profile accuracy - very easy to automate - dressing with production speeds Layer rim Clamp collar Body Fixing screw PLEASE NOTE Further information and types of form rollers for CNC dressing can be found in catalogue ‘Dressing Tools for Dressing Grinding Wheels’.

ROUND TOOLS NORTON WINTER PRECISION TECHNOLOGY TOOL GRINDING / 25 µicro + PRECISION FLUTE GRINDING FOR MINI AND MICRO TOOLS As well as innovation in new materials and tool designs, the recent trend towards miniaturisation has become considerably more important. From mini- and micro- down to nano tools, nowadays tools with outer diameters below 0.1 mm are no longer exceptional. The production of these tools demands special grinding wheels with very small and stable edge radii. Resin bonded grinding wheels are competing against metal bonded versions which are considerably slower by comparison (approx. 50 % of the feed rate of resin bonds) but they are characterized by greater edge stability. Metal bonded grinding wheels achieve a dressing interval up to five times longer. The decision whether to use resin bonds or metal bonds is often a matter of personal preference. It is a question of process control whether profile retention with slower feed rates or high output with high feed rates will be cost-effective. The Norton Winter range therefore consists of metal bonds with great edge stability (BZ bonds for diamond and MSS bonds for cBN) as well as resin bonds with perfect edge stability which are marketed under µicro+ brand. The tools of the Norton Winter μicro+ range are grinding wheel systems that have been specifically developed for these requirements, which despite fast feed rates are characterised by their perfect edge stability compared to traditional resin bonds. AREAS OF APPLICATION Classic areas of application are mini and micro drills and end mills for electronics, medical technology and automotive industry. In addition, these grinding wheels can be used for similar metal removal tasks, e.g. burrs.

Occasionally, 1A1 and 11V9 wheels are used. The advantage of 1V1 wheels over 12V9 wheels is a more rigid body.

One or two clearance angles are usually ground on the face. Up to two clearance angles / clearances can be produced on the circumference; on some tools these take the form of radial clearance grinding. For grinding clearance angles 11V9 cup wheels or similar geometries are typically used. Our extensive standard range can be found on the following pages of this catalogue. 12V9 or surface grinding wheels are also used. Compatible tools with these geometries are listed in the chapters on flute grinding and gashing.
