Japanese precision equipment manufacturerSugino Machine Limited已经启动了一个混合系统，该系统将CNC加工与激光金属沉积（LMD）3D打印相结合。
By incorporating aHybrid Manufacturing TechnologiesAMBIT printhead and CNC machining head, the ‘XtenDED’ is said to be capable of producing and finishing parts with a greater throughput and accuracy. Thanks to its compatibility with nickel superalloys, cobalt-base superalloys and stainless steels, the machine could address demanding aerospace applications, where heat resistance is vital.
Sugino’s existing equipment offering
Initially founded in Japan in 1936, Sugino’s business is primarily focused on the manufacture of systems for the high-pressure cleaning, deburring, machining, drilling, tapping, burnishing and waterjet cutting of parts. Over the last 86 years, the firm has expanded significantly, opening a US division in 1980, but it continues to focus on helping clients drive manufacturing reliability, flexibility and accuracy.
The majority of the company’s current offering is targeted towards post-processing, and includes everything from high-pressure cleaning and deburring machines, to dry burst milling systems and burnishing tools.
That said, Sugino’s portfolio has long-included a range of CNC machining centers and modules. The firm’s Xion-II 5AX Compact Precision 5 Axis Center, is designed for precision machining while maximizing floor space, and running at up to half the operating cost of competitors. With the H-720, meanwhile, Sugino markets a system with a horizontal design, making it ideal for fitting to index machines.
Xted制造能力
At the core of the XtenDED is a twin-head setup that combines the AMBIT laser processing head with the tool magazine of a CNC machine. Hybrid Manufacturing Technologies’ portfolio of AMBIT heads is designed to turn machines into hybrid production, finishing and inspection tools, making them ideal for Sugino’s dual-function system.
On the XtenDED, the printhead works by using a laser to melt powder feedstock as it arrives at the surface of a workpiece, and as this material cools, more layers can be added on top. By positioning a CNC machining head directly alongside this Directed Energy Deposition (DED) technology, the unit’s developer says it can post-process parts with improved accuracy, while driving productivity on the shop floor.
由于LMD使用的能量较少，并且更可控制的层到层，Sugino说，Xtended的热影响区（HAZ）也比等离子体或基于电线的3D打印机具有“明显较小的热影响区（HAZ）”。该公司补充说，这使该系统“比单独进行加工的浪费少，而不是单独打印的生产力和精确性更高”，同时使其能够为用户提供两种技术的最佳状态。
In practice, the 300 x 400 x 200 mm machine is said to accelerate the product design to manufacturing process, while addressing prototyping applications, and enabling metal part repair and resurfacing. Sugino is also marketing the XtenDED as means of combining different alloys to lend components corrosion or heat resistance qualities, in a process that can be completed in a matter of minutes.
