ITC Rounds On Trochoidal Milling Strategies With Extended 5021 Series

With trochoidal milling being the buzzword among the cutting tool fraternity, Industrial Tooling Corporation (ITC) Ltd has a complete section of its 2017 product catalogue dedicated to this machining process.

For engineers less familiar with the process, Issue 12 of the ITC product catalogue identifies the benefits and potential savings that can be achieved with trochoidal milling. This is followed by an extremely comprehensive line of applicable products that will deliver astounding results using the trochoidal machining process. In fact, the Tamworth manufacturer of cutting tools has extended one of its most popular end milling lines especially for trochoidal machining.

The square-end 5021 Series of 5-flute end mills has now been extended to incorporate a complete range of corner radii for each diameter in the series. Previously, this Cupro coated long length end mill with a harmonic flute geometry for improved chip evacuation and extended tool life was available as a square–end series from 3 to 25mm diameter. Now, taking into account the upsurge in innovative new machining strategies, ITC has massively extended the 5021 Series by incorporating a number of corner radii of each diameter.

The smallest 3, 4 and 5mm diameter tools now include a 0.25 and 0.5mm corner radius whilst the 6mm tool adds a 0.75 and 1mm radius. For the 8, 10, 12, 16 and 20mm tools the diameter increments above 1mm increase in 0.5mm increments all the way up to a 3mm radius on the 16mm tool and a 4mm radius on the 20mm tool. The extended 5021 Series is supplied with an overall length from 58 to 150mm and a flute length from 9 to 40mm.

This optimised geometry combines with the sub-micron carbide substrate and the extremely wear resistant Cupro coating to deliver reduced torque and load on the machine tool which is credit to a smooth cutting action that improves swarf evacuation and reduces the temperature during machining. The composition of the 5021 Series makes it the tool of choice for machining steel and exotic materials that inherently increase the temperature and stress on the cutting tool. However, these issues are a thing of the past with the 5021 Series as its harmonic flute geometry and centre cutting action guarantee a consistent chip thickness as well as a constant delivery of torque through the spindle.
