Info v c Product Finder 2.8 Other EMUGE abbreviations IKZ IKZN Internal coolant supply, axial (DIN designation: KA) The axial exit of coolant-lubricant provides optimum cooling and lubrication in the lead taper area. Internal coolant supply, axial, with coolant exiting in the flutes (DIN designation: KR) Radial exit of coolant-lubricant is the safest solution for providing coolant supply in the lead taper area even in through holes. VHM Solid carbide Tools with a thread diameter < 12.0 mm are made of solid carbide (thread part and shank). 2.9 Lead taper forms Lead taper forms and lead taper lengths for roll form taps acc. DIN 2175. Form C Form D Form E Lead taper length 2-3 threads Lead taper length 3-5.5 threads Lead taper length 1.5-2 threads The chamfer length of our EMUGE taps is adjusted to the workpiece material in each individual case. 2.10 Cooling and lubrication agents Lubricants are often, if not generally, given too little consideration. If you want to get the best performance out of your tool you have to take care to use the best coolant-lubricant available. In general, we distinguish the following types of cooling and lubrication: A Dry machining, pressurized air, cold pressurized air “Real” dry machining is mostly used only in cast iron. Pressurized air, sometimes cooled, is used in some cases for chip removal. E M Emulsion The most common type of coolant-lubricant on machining centres. Minimum-quantity lubrication (MQL) Due to the more and more common option of supplying aerosol through the spindle on modern machining centres, this type of cooling and lubrication is gaining more and more popularity. O P Thread cutting oil With these oils which are perfectly adjusted to specific materials, excellent thread surfaces and tool life can be achieved. Thread cutting paste Perfectly suitable for the cold forming of threads. Especially useful in horizontal machining, with large thread sizes and through hole threads. To be used only for brush lubrication.
