SINUMERIK 828 – Optimum scalability in the compact class

Alongside two high-performance CNC variants of SINUMERIK 828D, SINUMERIK 828D BASIC is a low-cost starter model in the compact class. SINUMERIK 828 therefore fits the performance requirements of standard machine concepts perfectly.

Compact, strong, simple – simply ingenious

The compact, operator-panel-based SINUMERIK 828 CNC systems are extremely rugged and very easy to maintain.

An operator panel front of die-cast magnesium, the panel-based CNC design with minimal interfaces and the high degree of protection make the SINUMERIK 828 CNC systems reliable partners even in harsh environments. Designed without a fan or hard disk, with NVRAM memory technology and no back-up battery, SINUMERIK 828 is a completely maintenance-free CNC.

Powerful CNC functions coupled with unique 80-bit NANO^FP accuracy allow excellent workpiece precision to be achieved in very short machining times. Thanks to a flexible CNC programming language as well as the unique machining step programming package ShopTurn/ShopMill, it is possible to program and machine mass-production parts or single workpieces with highest efficiency. Preconfigured technology-specific system software and unique service functions reduce the costs of commissioning and servicing to an absolute minimum.

Technology tailor-made for use in standard turning and milling machines

SINUMERIK 828D is perfectly adapted to use in standard machines and provides optimum support for turning and milling technology. With two preconfigured system software variants for machining technology, the SINUMERIK 828 CNC systems are ready for use in turning and milling machines on dispatch from the factory.

An ideal basis for implementing a compact grinding machine

The G-Tech technology variant provides grinding machine manufacturers with a perfect platform on which to design grinding machines – it supports cylindrical as well as surface grinding machines.

Since grinding machine manufacturers fully incorporate their specific process know-how so that it is even reflected in the operating philosophy of the CNC, the G-Tech variant of the SINUMERIK 828D offers a number of sophisticated grinding and dressing cycles for this purpose. At the same time, SINUMERIK Integrate for engineering Run MyScreens provides manufacturers with the option of designing their own HMI.

The right performance for the relevant technology – scalable by selection of appropriate software

SINUMERIK 828D offers the right performance level for any compact machine. One of four different performance variants can be used depending on the requirements of the application in terms of channels, axis quantity structures, and the cycle times of the interpolator and position controller. The performance variant is numerically coded. The following variants are available:

• SW 24x
  Performance variant PPU 240/PPU 241
• SW 26x
  Performance variant PPU 260/PPU 261
• SW 28x
  Performance variant PPU 280/PPU 281
• SW 28xA
  Performance variant PPU 280 advanced/PPU 281 advanced

The full software designation is thus formed in conjunction with the name of one of the technologies indicated above. No performance variant PPU 28x , i.e. no software variant SW 28x Grinding, is available for the G-Tech variant.

The SINUMERIK 828D supports three technology variants: Turning, Milling, and G-Tech The relevant software variant is selected accordingly. The name of the technology variant is added to the end of the software designation, i.e. SW 2xx Turning for a lathe.

Bundling of software and hardware

The bundling process is completed by selection of suitable control system hardware (PPU). Three vertical PPUs 2x0.3 and three horizontal PPUs 2x1.3 are available for selection.

Example 1:

This means that software package SW 24x Turning is required for a lathe with 4 axes/spindles. It must then be decided whether the vertical or horizontal variant of the control system will be used. The horizontal variant is the better option for lathes so that PPU 241.3 is selected for this example application.

Example 2:

This means that software package SW 26x Milling is required for a milling machine with 6 axes/spindles. It must then be decided whether the vertical or horizontal variant of the control system will be used. The vertical variant is the better option for milling machines so that PPU 260.3 is selected for this example application.
