JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC Europe 2015 - The CoroMill Plura PCD end milling cutters are designed purposely for performing edging, surface milling, slotting and cutting operations on workpieces made from carbon fibre-reinforced plastic (CFRP).
All CFRP components – common in the aerospace industry – need to be trimmed to the right shape due to the way these innovative materials are produced. These milling cutters offer long tool life and predictable wear patterns, which are vital when machining composite parts in order to avoid downtime and rework/scrap. Available in a diameter range of 6-16 mm and based on a high-performance PCD grade optimized for CFRP, the endmills offer internal coolant and 5° ramping capability. Sandvik Coromant has developed the PCD grade to offer the longest possible tool life. However, the end mills can also be reconditioned as and when required. In terms of technical recommendations, for best results it is advisable to ensure the end of the cutter is 1 mm under the composite material, while conventional (up) milling gives less vibration and is preferable. The recommended maximum thickness of the material is 2 mm less than the length of the PCD section of the tool tip. Typical 2D surface machining applications permit a cutting speed in the region of 200-400 m/min, in combination with feed rates of 0.03-0.06 mm/rev for roughing, or 0.02-0.04 mm/rev for finishing. The new cutters are a complement to the Sandvik Coromant drilling offer in CFRP.More information: www.sandvik.coromant.comBooth: Q42
