GBP 57 ​ Micro-lubrication system, patented Sturdy stainless steel body with 3-chamber pressure system for dispensing the lubricant very accurately. Ds Advantage: ■ Very easy to operate. ■ No problematic, inaccurate manual lubrication. ■ Process reliability and longer tool life. Application: Can be used horizontally and vertically in machining centres. For all thread cutting oils up to 570 mm2/s viscosity (see No. 084210 and 084220). The oil is precisely distributed mechanically and hydraulically on to the tapping hole wall. Because the micro lubrication system efficiently uses only very small quantities of oil, an impairment of the consistency of the emulsion is prevented. It thus saves the significant expense of changing over to emulsion with a high fat content, which is essential for process reliability when tapping. Supplied with: Micro lubrication system, main cylinder type S, and one each nozzle type DL and GL filling injector. Note: ■ For accessories and spare parts see the spare parts list.

It is also imperative to pay attention to the type of cooling lubricant. To determine the intended cooling lubricant and the process, the respective specification in the application table under the products is used: Example and explanation* Minimal quantities of Suitable only under Oil lubrication Compressed air supply ○ lubricant restricted conditions Emulsion (for taps Dry machining ● Suitable Unsuitable with at least 8% grease) *In addition, the recommendations in the product description must be observed. 1270
