The new CoroMill Plura cutter Sandvik Coromant offers optimized high-performance milling and grooving applications such as CFRP (Carbon Fiber Reinforced Composites) and GFRP (Glass Fiber Reinforced Composites).Production engineers, machine shop managers and operators will benefit the new milling cutter with patented troughs, especially in the aerospace industry where these materials are becoming more common, as well as automotive, motorized, wind power and shipbuilding industries The Solutions for specific composite materials are becoming an increasingly important factor for machine-shop workshops that seek improvement in quality,production cycle and cost. The abrasive content of many composites can cause problems such as fast tool wear, reduced cutting quality, increased temperature, unstable vibration and cutting conditions. Taking into account these challenges, the latest CoroMill Plura-based milling cutter Sandvik Coromant is designed to improve the processing of CFRP and GFRP on three-axis, four-axis and five-axis CNC machining centers, as well as gantry CNC machines and standalone arm systems Development.
"The CoroMill Plura brand has a long history and proven throughout the industry, and by virtue of this latest generation of milling cutters and specially designed patented troughs, it can improve the air quality," said Aaron Howcroft, product manager for global composite materials at Sandvik Coromant.The processing capacity of aerospace composite parts, including fuselage, wing, stabilizing wing, beam, ribs, ribs,structures, floor beams, pillars and pressure tanks. Milling cutters provide high productivity, with the longest on the market In addition, they can also be a standard product for quick order, to facilitate the procurement team. "
When milling and grooving the composite, the new milling cutter is mainly used for full radial feed and full slot milling. In some cases, you can also deploy finishing passes. The helical angle design ensures ideal sharpness and cutting edge strength, resulting in longer tool life and high quality surface, edge and groove surface quality. The series includes 3 knives: CoroMill Plura herringbone cutter, CoroMill Plura small spiral angle cutter and CoroMill Plura sawtooth cutter.
CoroMill Plura herringtes with double 40 ° helix, especially for CFRP parts with glass fiber cladding. Due to the overlap between the chevrons, the milling cutter can perform well by reducing the vibration of the material in thin, flat materials.
CoroMill Plura Small Helix (5) Milling Cutters are designed for smooth, burrless finishing requirements in CFRP workpieces with a large number of teeth designed to help quickly cut and coat heat. The right-hand and left-hand cutting edges are designed to be flexible in applications where the workpiece material is not stuck, such as weaker or damaged fixtures.
Finally, the CoroMill Plura sawtooth has a large chip flute, so the material removal rate is very high. In addition, the groove type also provides a double cutting effect to reduce the stratification and vibration, and ultimately provide a tool to minimize the stress on the composite parts of the knife processing solutions.
The 3 CoroMill Plura milling tools are available with or without coolant.
山特維克可樂滿推出的全新CoroMill Plura銑刀可在諸如CFRP (碳纖維增強(qiáng)復(fù)合材料) 和GFRP (玻璃纖維增強(qiáng)復(fù)合材料) 中提供優(yōu)化的高性能銑削和開槽加工。生產(chǎn)工程師、機(jī)修車間經(jīng)理和操作人員都將受益于這些擁有專利槽型的全新銑刀，尤其是在這些材料使用越來越普遍的航空航天行業(yè)，以及汽車、 摩托運(yùn)動(dòng)、風(fēng)力發(fā)電與船舶等行業(yè)。
對(duì)于在質(zhì)量、生產(chǎn)周期和成本方面尋求改進(jìn)的機(jī)加車間，專門用于特定復(fù)合材料加工的解決方案正在成為一個(gè)日益重要的因素。許多復(fù)合材料的磨料含量會(huì)導(dǎo)致諸如刀具磨損快、切削質(zhì)量下降、溫度升高、振動(dòng)和切削工況不穩(wěn)定等問題?？紤]到這些挑戰(zhàn)，山特維克可樂滿的最新CoroMill Plura一代銑刀專為改善在三軸、四軸和五軸數(shù)控加工中心，以及龍門式數(shù)控機(jī)床和獨(dú)立機(jī)械臂系統(tǒng)上的CFRP和GFRP加工而開發(fā)。
山特維克可樂滿的全球復(fù)合材料產(chǎn)品經(jīng)理Aaron Howcroft說，“CoroMill Plura品牌歷史悠久，且在整個(gè)行業(yè)中久經(jīng)驗(yàn)證，憑借這種最新一代的銑刀和專門設(shè)計(jì)的專利槽型，可以提高航空航天復(fù)合材料零件的加工能力，其中包括機(jī)身、機(jī)翼、安定翼、梁、筋條、翼肋、框架結(jié)構(gòu)、地板梁、支柱和壓力艙。 銑刀可提供高生產(chǎn)率，擁有市場上最長的刀具壽命。此外，它們還可作為標(biāo)準(zhǔn)產(chǎn)品進(jìn)行快速訂購，為采購團(tuán)隊(duì)帶來便利。”
當(dāng)對(duì)復(fù)合材料進(jìn)行銑削和開槽操作時(shí)，全新銑刀主要用于全徑向進(jìn)給和滿槽銑削。在某些情況下，還可以部署精加工走刀。螺旋角設(shè)計(jì)可確保理想的鋒利度和切削刃強(qiáng)度，從而實(shí)現(xiàn)更長的刀具壽命以及高質(zhì)量的表面、邊緣和溝槽的表面質(zhì)量。該系列包括3款刀具：CoroMill Plura人字形銑刀、CoroMill Plura小螺旋角銑刀和CoroMill Plura鋸齒銑刀。
CoroMill Plura人字形銑刀帶有雙40°螺旋，尤其適用于帶有玻璃纖維覆層的CFRP零件。由于人字形容屑槽之間存在重疊，因此銑刀可通過降低材料振動(dòng)在薄、扁平的材料中表現(xiàn)良好。
CoroMill Plura小螺旋角 (5°) 銑刀專為CFRP工件中的光滑、無毛刺精加工要求而設(shè)計(jì)，帶有大量的齒旨在幫助快速切削和涂層防熱。右旋和左旋切削刃設(shè)計(jì)使其能夠靈活的運(yùn)用在工件材料裝夾不穩(wěn)定的場合，例如較弱或受損的夾具。
最后，CoroMill Plura鋸齒銑刀具有較大的容屑槽，因此材料去除率非常高。此外，槽型還提供了雙重切削作用，以減少分層和振動(dòng)，最終提供一個(gè)能夠盡量減少復(fù)合材料零件上應(yīng)力的刀加工解決方案。
這3款CoroMill Plura銑刀在有或沒有冷卻液的情況下均可使用。
