    Siemens 808D CNC Retrofit Solutions

    Best Value, Low-Cost CNC Retrofit Solution

    We are proud to offer not only the lowest cost Siemens CNC Retrofit Solution in the industry, but the best value low-cost CNC system available. Siemens SINUMERIK controls have set the standard for quality in the machine tool industry for more than 50 years. The Siemens 808D and 808D Advanced CNC Systems offer the same quality that Siemens is known for – at a price that even small shops can afford.


    Wide Range of Machine Tool Applications

    Our Siemens SINUMERIK 808D Low-Cost CNC Retrofit Kit for Milling is perfect for 3-Axis Knee Mills, Vertical Machining Centers, and Routers. The control system is suitable for any machine that has 3 interpolating axes. Servo motors are available up to 10 Nm, which makes the 808D CNC a great option for small to mid-size machines. The SINUMERIK 808D ADVANCED, at a slightly higher price point, has 4-Axis capabilities and offers servo motors up to 40 Nm. This allows the 808D ADVANCED to cover a wider range of applications, such as mid-sized VTLs and boring mills. For machines that require larger motors we move up to the Siemens SINUMERIK 828D CNC, or use another control platform.

    Maximum Precision and Accuracy

    SINUMERIK 808D / 808D ADVANCED offers a calculation accuracy in the nanometer range – far beyond what even a high-end machine tool can achieve. Both CNCs also feature an intelligent jerk limitation function. This bellprofile acceleration characteristic not only guarantees smooth path behavior, but also reduces the stress on the mechanical system of the machine. As a result, SINUMERIK 808D / 808D ADVANCED guarantees maximum workpiece precision.

    Technology Cycles for Milling and Turning

    When it comes to drilling and milling operations, SINUMERIK 808D / 808D ADVANCED is a top performer. Boring, centering, drilling, thread milling, pocket machining are no problem! There is even a machine cycle to support parameter input for high-speed mold & die applications. For turning a wealth of functions are available, such as machining standard contours, grooves and thread undercuts, cutting of various thread types — and even a powerful contour stock removal cycle. These cycles allow the optimum performance to be obtained from turning machines with just a few parameter settings.

    Operator Friendly CNC Programming

    SINUMERIK 808D / 808D ADVANCED offers the common ISO code programming language. This allows operators familiar with other ISO-based CNC systems to quickly make a transition to SINUMERIK 808D / 808D ADVANCED. In addition to the standard G codes, such as G01, G02, canned cycles like G81 or G74 are also available. If an operator requires more technological features, the standard ISO codes can be mixed with high-level SINUMERIK CNC commands.

    High-Speed Means High Productivity

    The SIMOTICS S-1FL6 motor, available with the 808D Advanced, has a maximum speed of 4000 rpm, so that axes can be operated up to their physical limit. Thanks to the 300% overload capability of the SINAMICS V70 drive and SIMOTICS S-1FL6 motor, faster acceleration and deceleration are possible with SINUMERIK 808D ADVANCED. As a result, the non-cutting operating times of basic machines are reduced and higher productivity is achieved.

    PC-Style File Handling

    With SINUMERIK 808D / 808D ADVANCED, part programs in a linear memory and names in the form of cryptic numbers are thing of the past. Part programs can be allocated meaningful names and the CNC memory can be easily structured by using sub-folders — just the same as for a PC.
