7. ne before accessing the electrical equipment Do not rely on simply switching off power when working on the electrical system ALWAYS disconnect the power supply physically from the equipment before commencing to work on it 2 COMPONENTS The thread cutting machine consists of following components see picture 1 Picture 1 2 1 The thread cutter A which is fitted in high speed milling power tool B that has been mounted on a compound table C This compound table is fixed on a base plate D The cutter can be positioned by means of the compound table at the outside for making external screw thread or the inside for making internal screw thread on the already on the lathe prepared lids and containers 2 2 The thread pitch feeding system E is also fixed on the same base plate The pitch feeding system and compound table can be fixed at different locations see pictures 3 and 2 in order to adjust the system to the height of the products to be threaded A 3 positions 3 positions Picture 2 riciure 3 It has standard been installed with a thread feeding system with a pitch of 2mm Other feeding systems with a pitch of 1 5mm 1 75mm 2mm and 2 5mm are also available as an option see also 6 Cutting the thread 3 ADJUSTMENTS Following adjustments should be done before making external and internal screw threads 3 1 Compound table 3 1 1 Alignment The compound table C needs to be correctly aligned parallel with the
8. nst it Wear eye protection with an industrial impact rating at all times when working on the Tread cutting machine Ear protection is also recommended as it will help reduce aural degeneration which is a cumulative effect The use of accessories and replacement parts supplied by third parties may expose the user to hazards The use of approved accessories and the fitting of spare parts supplied by the original equipment manufacturer WivaMac is strongly recommended WivaMac will not be responsible under product liability regulations for any damage resulting from the use of parts and accessories from other sources The operational instructions this manual should be made available to all operators of this machinery and operators should be advised of the potential hazards of Tread cutting machine operation including environmental risks before they are allowed to use the Tread cutting machine Do not operate the Tread cutting machine with covers removed or other safety equipment broken disabled missing or otherwise inoperative Repairs to the Tread cutting machine and its installation should be undertaken only by qualified personnel Always disconnect the power supply before opening or working on associated electrical equipment Be aware that potentially lethal residual voltages may be present for some minutes even after the power source has been removed Always wait several minutes after removing power from the Tread cutting machi

10. ore starting to cut the thread one should verify whether the product is positioned centric around the centre line and does not wobble by rotating the pitch feeding screw F If not centric reposition the product in the chuck until it is rotating perfectly centric If not the screw thread will not be evenly deep over the circumference In order to avoid this adjustment process we recommend to leave the product that have been pre turned on the late in the chuck and mount the chuck with the product directly on the thread pitch screw E without repositioning it The standard screw thread to mount the chuck on the pitch feeding system is M33 x 3 5mm Eventually an adapter can be used 4 PREPARING THE CORRECT DIAMETERS When preparing the work pieces care must be taken that the diameter of the section where external threads are going to be cut D in picture 13 is greater than the diameter of the mating section where internal threads are being cut d in picture 13 d D 1 x pitch The difference between these two diameters may not be greater than once the pitch of the thread If for example you want to cut a thread with a 2mm pitch on a 40mm piece of wood then the hole for the internal thread should not be smaller than 40mm 2mm 38mm If the wood is not completely dry which is often the case it is advisable to make the difference between the two diameters just a little less Picture 13 5 CUTTING THE THREAD Mou
