Siemens Drive Technologies has extended its portfolio of controls to include an efficient CNC Design for compact class machine tools. The new Sinumerik 828D, alongside the Sinumerik 802D sl for standard machine applications and the 840D sl for high-end machining applications, now offers users a new system designed to address the needs of complex turning and milling machines in the job shop segment. Featuring intelligent kinematic transformations, an efficient tool management system and 80-bit precision, the new control benefits from a range of performance features previously reserved exclusively to the premium CNC control segment.
The system is suitable for both single part and small batch, as well as large-scale series production. Use of the ShopMill and ShopTurn graphic workstep programming systems helps reduce programming time when producing small batch sizes. For large-scale series production, high-level language programming, in conjunction with programGuide for technology cycle parameterization reduces programming times. The Sinumerik 828D also supports ISO programming and as such, is capable of working with most types of CNC programming methods used globally. This enables machine manufacturers to market their products internationally with just a single CNC equipment option.
The Sinumerik 828D makes available modern PC and cell phone technology to the compact machine class for the first time. Graphical online help, animations and a new type of input prompting system with moving picture sequences makes operation convenient and easy for users. USB, Compact Flash (CF) card and Ethernet ports permit simple high-speed data transfers onto storage media or integration of the control system into corporate networks. With its Easy Message functionality, the Sinumerik 828D offers process monitoring by text messaging (SMS). Depending on the recipient’s profile setting, the machine will transmit information about workpiece machining status, report on the tool condition currently in use and even send machine maintenance bulletins.
The Sinumerik 828D can easily be configured for milling or turning applications. The milling version is customised to the requirements of vertical machining centers with additional machine units such as an A-axis for machining cylindrical workpieces or a swivel facility for machining inclined workpiece planes. The intelligent path guidance system, Advanced Surface, means the Sinumerik 828D can also be used for the production of high-precision molds. The turning version is specifically designed for single-channel inclined-bed lathes.
The Sinumerik 828D is available with a horizontal and vertical control panel layout. Both control panel versions come in a choice of two CNC performance variants so that the Sinumerik 828D can be adjusted to specific mounting requirements and individual machine performance requirements. Despite the reduced size of the control, the high-resolution 10.4” color TFT display and fully functional QWERTY keyboard make it user-friendly. The unit comprises of a tough and wear-resistant die cast magnesium control panel and is maintenance-free with no fans, hard drive or backup battery.
