5 1 Application range, safety instructions and technical data 1.1 Application range, determined use The quick-change tap holders are mainly used on CNC machining centres, CNC turning lathes and conventional machine tools. The quick-change tap holders are marked by a yellow ring at the grip sleeve, see Picture 1, page 6. The quick-change tap holders are equipped with one of the following shanks: Morse taper shank acc. to DIN 228 B (ASME B 5.10) Cylindrical shank acc. to DIN 6327 or ASME B 5.11 Taper shank acc. to DIN 2080 or ASME B 5.18 or DIN A or ASME B 5.50 metric or ASME B 5.50 UNC or JIS B 6339 Cylindrical shank acc. to DIN ISO (DIN 69880) or DIN1835 B+E or ASME B Weldon Hollow taper shank acc. to DIN A or DIN C ABS-clutch For the cutting range of each type please refer to Table 1, page 6. The locking of the tool is executed via quick-change adapters type EM. The quickchange adapters must be chosen depending on their size and the tool used, see chapter 2.4, page 8. The quick-change tap holders are equipped with a length compensation on tension and on compression, with a pressure point mechanism and a front release, see chapter 1.2, page 4. The quick-change tap holders (marked by a yellow ring) are not suitable for internal-lubricant coolant supply. The non-determined use exempts the manufacturer from any liability. Edition:

6 1.2 Specifications Further features of the quick-change tap holders are: - Small and compact overhang length - Length compensation in compression direction: Compensates differences between spindle feed and the pitch of the thread to be produced. When using quick-change adapters with overload clutch, the length compensation on compression takes on the spindle feed as soon as the overload clutch is activated. - Length compensation in tension direction: Compensates differences between spindle feed and the pitch of the thread to be produced as well as an overrun of the spindle in the reversing point of the thread producing cycle. - Front release: The front release protects the quick-change tap holder, the quick-change adapter and the tool as well as the workpiece against damage caused by the axial tension load being too high. Such tension may occur if the length compensation movement is exceeded, i.e. because the machine spindle overruns in the reversing point of the thread producing cycle or the fast-feed function is activated before the tool has come free from the workpiece. In these situations, the quickchange adapter disengages automatically from the quick-change tap holder and avoids expensive damages. - Pressure point mechanism: The pressure point mechanism guarantees the safe cutting of the tool. Only when the effective occurring axial force exceeds the allowed cutting or forming force, the pressure point mechanism sets the length compensation movement free. Repeatable and regular thread depths are reached. 4 Edition:

7 1.3 Safety instructions For all works for example putting into operation production and maintenance, please observe the details given in the operating instructions. All relevant safety regulations as well as local instructions are to be observed when working with the quick-change tap holders. Below please find some basic rules: - Please wear gloves during tool change to avoid injury. - Basically change the tool yourself to avoid the sudden start of the spindle caused by mis-operating. - Hold the tool when loosening the tool clamping to avoid it falling down and damaging the tool and the workpiece. - Please keep the tool adaptation clean. - There are maximum values for cutting speeds and feeds for every kind of machining. Please observe such data. - Please observe the maximum tool dimension - Furthermore, the instructions of the tool manufacturers are valid! Edition:

9 2 Putting the quick change tap holders into operation 2.1 Unpacking - Take the quick-change tap holder from the plastic case - Clean the quick-change tap holder with a duster to remove any conservation oil Do not use any aggressive solvents. Do not use any fibrous materials, i.e. steel wool. The quick-change tap holder is now ready for operation! 2.2 First putting into operation The quick-change tap holders are inserted into the machine manually or if provided by the tool exchanger. The exchange of the quick-change tap holder must not be executed while the machine spindle rotates! - Only use tool shanks and tightening bolts suitable for the specific machine. - Make sure the tool is correctly clamped. Risk of accident by spinning of the tool! - Please see also the indications in the operating instruction of your machine tool! 2.3 Re-putting into operation In case the quick-change tap holder is reput into operation as described in chapter 4, page 15, please carry out the following steps: 1. Clean the quick-change tap holder with a duster to remove the conservation oil Do not use any aggressive solvents. Do not use any fibrous materials, i.e. steel wool. 2. Check function of the length compensation: Stretch and compress the quick-change tap holder at the grip sleeve, let go off the grip sleeve the quick-change tap holder must independently return to its initial position 3. Exchange the quick-change tap holder into the machine as described in chapter 2.2 Edition:

10 2.4 Application and choice of the quick change adapters The adaptation of the tool is executed via quick-change adapters. The following quick-change adapters are available. Type EM.. Type EM..-E-Lock Type EM..-U Type EM..-L Type EM..-UL Type EM..-Z Rigid type, without overload clutch. Application range: Production of through hole threads Rigid type, without overload clutch, locking of the tool is secured by form-fitting. The tool must be provided with a groove at one square face. Application range: Clamping of carbide tools, with high coolant-lubricant pressures and in high-speed machining With adjustable overload clutch. Application range: Production of blind hole threads With length adjustment, without overload clutch. Serves for pre-adjusting the tools in the quick-change adapters outside the machine. Application range: on multi-spindle heads and transfer lines With adjustable overload clutch and length adjustment. Application range: Production of blind hole threads on multispindle heads Rigid design with adaptation for collets type ER (GB) Application range: Clamping of carbide tools, with high coolant-lubricant pressures and in high-speed machining Type EM..-L/ER/IKZ With length adjustment and adaptation for collets type ER (GB) Application range: multi-spindle heads and transfer lines, for clamping of carbide tools, with high coolant pressures and in high-speed machining Type EM..-PGR Rigid design with adaptation for collets type PGR (GB) Application range: clamping of carbide tools, with high coolant pressures and in high-speed machining Type EM..-SE Rigid design with adaptation for dies acc. to DIN 223 Application range: Production of external threads Type EM..-ELSE Type EM..-R Rigid design for adaptation of Elastic dies Application range: Production of external threads Reducing adaptation for all EM types Application range: for the extension of the clamping range downwards 8 Edition:

11 The tool adaptation is executed via a quick-change-ball-clamping system except for type EM-Z, EM-L/ER/IKZ and EM-PGR. The torque arising during the thread producing operation is transferred over the square in the quick-change adapter. The adaptation of dies is carried out via mechanical locking. All quick-change adapters are suited for producing right- and left-hand threads. The adapter sizes for the appropriate quick-change tap holder may be taken from table 1, page 6. The clamping diameter is defined by the tool used. Each diameter requires a separate quick-change adapter. Edition:
