Engine power consumption Drilling capacity End Milling capacity Face Milling capacity Working radius Spindle taper Spindle stroke Headstock tilt Cross travel Longitudinal travel Vertical travel Table size Spindle speeds T slot size Motor Dimensions Net Weight 240V / 50Hz / 600W 16mm 16mm 52mm 175mm MT2 52mm ±90º 160mm 440mm 200mm 500 x 140mm 50-2500rpm 10mm 600W (0.8hp) 520 x 550 x 800mm 75kg Emissions The noise level (emission) of the drilling-milling machine ranges below 78 dB(A). If the drillingmilling machine is installed in an area where various machines are in operation, the acoustic influence (inmission) on the user of the drilling-milling machine may exceed 85 dB(A) in the working area. We recommend the use of soundproofing and ear protection. Remember that the duration of the noise pollution, the type and characteristics of the work area and operation of other machines influence the noise level in the working area. 8 3. Assembly and Connection The drilling-milling machine comes pre-assembled. 3.1 Extent of supply When the drilling-milling machine is delivered, check immediately that the machine has not been damaged during transport and that all components are included. Also check that no fastening screws have come loose. Compare the parts supplied with the information on the packaging list. 3.2 Transport Warning! Machine parts falling off forklift trucks or other transport vehicles could cause very serious or even fata injuries. Follow the instructions and information on the transport case: • Centers of gravity, • Suspension points, • Weights, • Means of transport to be used, • Prescribed shipping position. Use of unstable lifting equipment and load-suspension devices that break under load can cause very serious injury or even death. Check that the lifting and load-suspension gear has sufficient load capacity and that it is in perfect condition. Observe the rules for preventing accidents. Holds the load properly. Never walk under suspended loads. 3.3 Storage Improper storage may cause important parts to be damaged or destroyed. Store packed or unpacked parts only under the intended environmental conditions. Consult Chester UK if the machine or accessories have to be stored for a period of over three months or under different environmental conditions than those given here. 3.4 Installation and assembly The work area for operation, maintenance and repair work must not be hindered. The mains plug of the drilling-milling machine must be freely accessible. Proceed with extreme caution when lifting, installing and assembling the machine. Danger of crushing and overturning. • • 9 Secure the load-suspension device around the drill-mill head. Use a lifting sling for this purpose. Clamp all the clamping levers at the machine before lifting it. • Make sure that no add-on pieces or varnished parts are damaged due to the load-suspension. • Check the horizontal orientation of the base of the machine with a spirit level. • Check that the foundation has sufficient floorload capacity and rigidity. Insufficient rigidity of the foundation leads to the superposition of vibrations between the drillingmilling machine and the foundation (natural frequency of components). Insufficient rigidity of the entire milling machine assembly also rapidly causes the machine to reach critical speeds, with unpleasant vibrations, leading to bad milling results. • • Position the drilling-milling machine on the intended foundation. Attach the drilling-milling machine using the provided recesses in the machine base. 3.5 First use Cleaning and lubricating. Remove the anticorrosive agent applied on the drilling-milling machine for transport and storage purposes. We recommend the use of kerosene. Do not use any solvents, thinners or other cleaning agents which could corrode the varnish on the drilling-milling machine. Follow the specifications of the manufacturer of the cleaning agent. Cleaning the machine. Lubricate all bright machine parts with non-corrosive lubricating oil. Grease the machine according to the lubrication chart. Check smooth running of all spindles. Connect the electrical power cable (shockproof plug). 10 4. Operation 4.1 Safety Use the drilling-milling machine only under the following conditions. • • • • The machine is in proper working order The machine is used as prescribed The operating manual is followed All safety devices are installed and activated All anomalies should be eliminated immediately. Stop the drilling-milling machine immediately in the event of any anomaly in operation and make sure it cannot be started up accidentally or without authorization. 4.2 Controlling and indicating elements 11 4.3 Starting the milling machine By pressing the green button, the machine is switched on. By pressing the red button, the machine is switched off. The electrical system controls the speed with a ramp to the set value. Wait a little while before you continue with the feed when milling or drilling. 4.4 Inserting tools The mill head is equipped with an MT2 seat and a M10 draw-in rod. When milling operations are performed the cone seat must always be fixed to the draw-in rod. All cone connections with the taper bore of the work spindle without using the draw-in rod is not allowed for milling operations. The cone connector should be released by the lateral pressure. Injuries by parts flying off. In the work spindle you may only use tool holding fixtures and clamping tools with morse taper MK2 and internal screw thread M10 for an interlocking fixture. Reducing bushes is not allowed. • • • • • • • • Remove the cover. There is no need to disassemble the motor cover completely. Clean the conical seat in the mill head. Clean the taper mandrel of your tool. Press the mandrel taper with some push into the seat. If the taper mandrel does not hold by itself, either the taper mandrel or the taper bore of the work spindle are not clean or free of grease. Use the draw-in tool supplied with the machine - Hexagon socket spanner for draw-in rod - Hexagon socket spanner for draw-in nut Screw the draw-in rod approx. 15 turns into the taper of your tool Tighten the draw-in nut Follow the same steps in reverse order to extract the tool from the machine. Use of collet chucks When using collet chucks for the reception of milling tools, a higher operation tolerance is possible. The exchange of the collet chucks for a smaller or larger end mill cutter is performed simply and rapidly and the disassembly of the complete tool is not required. The work spindle is equipped with a surface for the hold-up with a fork wrench to unfasten the swivel nut of the collet chuck retainer. The collet chuck is pressed into the ring of the swivel nut and must hold there by itself. By fastening the swivel nut on the tool the milling cutter is clamped. Make sure that the correct collet chuck is used for each milling cutter diameter, so that the milling cutter may be fastened securely and firmly. 12 Direct clamping into the work spindle Tools or collet chucks with a MT2 shank may be clamped directly into the work spindle. For mounting these tools, proceed as described in ‘inserting tool’ on page 13. Make sure that the tool is clamped with the draw-in rod. 4.5 Changing the speed range Wait until the machine has come to a complete halt before changing the speed using the gear switch. • Turn the gear switch in the position ‘H’ for a speed range of 200 – 3000 min • Turn the gear switch into the position ‘L’ for a speed range of 100 – 1500 min • Adjust the speed with the potentiometer Selecting the speed For milling operations, the essential factor is the selection of the correct speed. The speed determines the cutting speed of the cutting edges which cut the material. By selecting the correct cutting speed, the service life of the tool is increased and the working result is optimized. The optimum cutting speed mainly depends on the material and on the material of the tool. With tools (milling cutters) made of hard metal or ceramic insert it is possible to work with higher speeds than with tools made of high-alloy high speed steel (HSS). You will achieve the correct cutting speed by selecting the correct speed. For the correct cutting speed for your tool and for the material to be cut you may refer to the following standard values or a table reference book. The required speed is calculated as follows: 13 Standard values for cutting speeds [m/min] with high speed steel and hard metal in conventional milling.

The tool should be cooled during the milling process. Cooling the tool with a suitable cooling lubricant ensures better working results and a longer edge life of the cutting tool. Use a water soluble and non-pollutant emulsion as a cooling agent. This can be acquired from authorized distributors. Make sure that the cooling agent is properly retrieved. Respect the environment when disposing of any lubricants and cooling agents. Follow the manufacturer’s disposal instructions. 14 4.6 Clamping workpieces Caution! Injury by flying off parts The workpiece is always to be fixed by a machine vice, jaw chuck or by another appropriate clamping tool such as clamping claws. 4.7 Swiveling the mill-drill head The mill-drill head may be swiveled to the left. Caution! The drill head may tilt to the right or the left on it’s own after loosening a screw. Proceed with extreme caution when loosening the clamping joints. • • • Loosen or unscrew the nut of the guide screw. Hold the drill-mill head. Loosen the clamping screw. Swivel the mill-drill head into the desired position. Retighten the guide and clamping screw. 4.8 Clamping levers The machine is equipped with clamping levers and screws for the respective movement axes. Use the clamping levers for locking the position of the axes during drilling or milling operations. 4.9 End stops adjustable end stops. The cross table is fitted with two Use the end stops for limiting the travel in order to guarantee the exact repeatability when manufacturing various technical components. 15 4.10 Installation on a lathe The mill head with column can be mounted on a lathe. For fastening an adapter is required. The adapter needs to be fixed to the engine bed. It is not possible to fix it to the lathe slide. The adapter is dimensioned in a way that the middle of the lathe chuck should be reached with the center of the milling spindle (alignment headstock – lathe chuck). Due to the manufacturing tolerances of castings and the manufacturing tolerances of two different machines it is however not possible to reach the exact center, the adapter may be too long or short. If required, the adapter is to be milled off or equipped with dummy sheets. When using sheets the complete surface is to be filled. In order to reduce the support expenditure of the column with milling head during the orientation we recommend you disassemble the milling head off the column. Unscrew the locking screw (safety screw) position 266. Disassemble the milling head off the column by completely loosening the clamping screw and the lead screw and stripping off the milling head. Control the orientation (90° angle horizonal and vertical) of the column with the reference planes on the engine bed of the lathe. In order to prevent you from having to reorient the milling head when altering later on, we recommend you to provide the column and the adapter as well as the engine bed with alignment pins. If required, pin the column together with the cross table before disassembling the column. It is recommended to use hardened straight pins according to DIN 6325 in 8mm or 10mm and a fitting tolerance zone m6. (zB. DIN 6325-8 m6 x 30). These alignment pins have a round cap on one side which facilitates pinning together the parts. When assembled the boring holes must be pilot-drilled to 0.2mm smaller and then rubbed with a reamer also when assembled. Ideally, use a new twist drill with a diameter of 7,8mm for alignment pins of 8mm. 16 5. Maintenance In this section you’ll find important information about • Inspection • Maintenance • Repair The diagram below shows which of these headings each task falls under: Properly performed regular maintenance is essential for safe operation, faulty-free operation, a long service life of the milling machine, and the quality of products that you manufacture. Installation and equipment from other manufacturers must also be in optimum condition. 5.1 Safety The consequences of incorrect maintenance and repair work may include: • Serious injury to personnel working on the milling machine • Damage to the milling machine Only qualified personnel should carry out maintenance and repair work on the milling machine. Only carry out work on the milling machine if it has been unplugged from the mains power supply, then pull the plug out. Restarting Before restarting the machine run a safety check. Before disconnecting the machine check that there is no danger for personnel and that the machine is undamaged. 17 5.2 Inspection and Maintenance The type and extent of wear depends on individual usage and service conditions. For this reason, all the intervals are only valid for the following authorized conditions: Interval Start of work After each maintenance or repair operation Start of work After each maintenance or repair operation Weekly Where? What? How? Drilling-Milling Machine Safety check Safety check Dovetail sideways Lubricate Lubricate all sideways Cross-table Lubricate Lubricate all blank steel parts. Use acid-free oil, for example engine oil An increased clearance in the spindles of the cross-table can be reduced by re-adjusting the spindle nuts. See spare parts drawing 1. The spindle nuts are re-adjusted by reducing the flank of screw thread of the spindle nut with an adjusting screw. By re-adjusting you can assure smooth running of the toolpath, otherwise the wear by friction between spindle nut/spindle would increase considerably. Swivel the mill-drill head to the right by 90°. Every six months Geared mill-drill Grease Detach the cover plate on the head rear side. Lubricate the gear wheels The spindle bearing arrangement is permanently lubricated. No new lubrication is necessary. As required Spindle nuts Re-adjust 5.3 Repair Any maintenance work may only be carried out by a specialized company or by a duly trained personnel. Any maintenance work on electrical equipment may only be carried out specialized electrical staff. For any repair work get assistance from our technical service team.
