Darex E-90 Drill Sharpener Sharpens Savings

The Darex E-90 end mill sharpener from workholding systems and manufacturing equipment specialist, 1st Machine Tool Accessories (1st MTA) provides a simple, convenient and accurate method of refurbishing milling tools without the expense of special purpose cutter grinding equipment or the need for highly trained operators. Enabling multi-flute end mills from 1.5 to 50 mm diameter to be quickly and easily re-sharpened in-house, the E-90 also offers substantial cost savings over external regrind services and, by ensuring maximum tooling availability, allows users to further trim manufacturing costs by minimising their tooling inventory. Suitable for 2, 3, 4 and 6-fluted end mills as standard, with optional 5 or 8-flute collets also available, the E-90 will sharpen both the primary and clearance angles on mill flutes and cutter ends in a single set up. It produces the required clearance angles using a unique stylus mechanism and will refurbish twin fluted 13 mm end mills in around two minutes. The E-90 accommodates flute lengths of up to 152 mm and will normally achieve payback within 12 months, based on resharpening 10 tools per week. It is equipped with a series of high precision, C5 type collets to suit 5-25 mm diameter mill shanks, or can be supplied with 32, 38 and 50 mm diameter collet adaptors to special order. The sharpener utilises a resin bonded super-abrasive CBN wheel, which delivers optimum cutter surface finish without burning, as well as a service life of several hundred HSS or cobalt tools. An optional 320 grit diamond wheel is also available for processing carbide tooling. The full range of Darex Drill Sharpeners are available from 1st MTA.
