SVM Series

The SVM Series vertical machining center delivers outstanding performance as one of DN Solutions (formerly Doosan Machine Tools) smallest vertical mills built for production. The SVM is ideal for aluminum die-castings in the automotive and IT industries with capabilities suited for light duty steel machining. With reduced acceleration/deceleration times on the XYZ axes and spindle, the SVM is optimized for shorter cycle times and non-cutting times.

Optimized Velocity for Shorter Cycle Times

The SVM 5100L is engineered as a High Productivity Swift Vertical Machining Center, specifically designed to minimize non-cutting time and boost overall throughput. This objective is achieved through rapid spindle acceleration/deceleration rates and high-speed motion dynamics. The SVM 5100L delivers a rapid traverse rate of 36 m/min (1,417 ipm) across the X, Y, and Z axes, complemented by efficient tool changes. The Double Arm Automatic Tool Changer (ATC) handles 30 tools with a swift tool-to-tool exchange time of just 1.3 seconds. Furthermore, the agile 12,000 rpm spindle boasts rapid acceleration from 0 to 12,000 rpm in 1.33 seconds and deceleration from 12,000 rpm to 0 in 1.25 seconds. This machine is optimized for specific demanding applications, particularly the machining of Aluminum die-castings in the Automotive and IT industries, while also being capable of general-purpose light duty machining of steel parts.

Structural Integrity and Advanced Spindle Technology

To guarantee maximum rigidity and stability under high-speed operation, the SVM 5100L is constructed on a Meehanite cast iron bed. This traditional design structure provides a solid platform necessary for fast, light duty machining. Positioning and repeatability accuracy are ensured by using preloaded, pre-tensioned, large diameter ball screws (32 mm / 1.26") directly connected to servo drive motors, which helps eliminate backlash and minimize thermal effects. The core of the machining capability lies in the Big Plus Spindle System, which utilizes simultaneous taper and flange contact between the machine spindle and the CAT 40 tool holder to achieve maximum rigidity, surpassing other spindle concepts. The direct-coupled, cartridge-type spindle drive minimizes noise, vibration, and thermal growth, supported by a dedicated oil jacket spindle chiller that circulates cooled oil to maintain accuracy.

Intelligent Monitoring and Process Control

The SVM 5100L is equipped with the FANUC 0i-Plus control interface and intelligent software features designed to optimize machining processes and protect tooling. Adaptive Feedrate Control (AFC) continuously monitors the spindle load during a cut and can automatically increase or decrease the programmed feedrate to compensate. AFC is capable of detecting air cutting to minimize wasted cycle time and initiating a "Feed Hold" state upon catastrophic tool failure or severe axis overload. The Tool Load Monitoring System further enhances reliability by checking the load on all axes and the spindle motor, allowing operators to set wear and breakage limits that trigger an alarm and stop operation when exceeded. Machine accuracy is further preserved by Smart Thermal Monitoring, a sensor-less, algorithm-based software that anticipates and compensates for spindle thermal deformation based on rotational speed.

Enhanced Machining Productivity Features

To support demanding production environments, the SVM 5100L comes standard with features that improve tool life and reliability. The Through Spindle Coolant (TSC) system uses a dedicated pump to deliver approximately 215–225 psi of pressure directly at the tool tip, enabling more aggressive feeds and speeds. For specific material needs, the machine also features Through Spindle Air (TSA), commonly used for pre-hardened steel, die and mold cutting, or applications where liquid coolant contamination is undesirable. Chip management is handled by dual screw-type augers that drive chips to the front of the machine. Furthermore, for simplified setup and inspection, the machine is Renishaw probe ready, equipped with the OMI-2T optical receiver and GUI software, prepared to accept spindle probes or tool setters. The machine also features an Eco friendly grease lubrication system, reducing maintenance and operational cost compared to oil systems.

FAQ Section

What specific industries and materials is the SVM 5100L optimized for?

The SVM 5100L vertical machining center was developed to meet the increased demand for machining of Aluminum die-castings in both the Automotive and IT industries. It can also be used for general-purpose light duty machining of steel parts.

How does the SVM 5100L ensure spindle rigidity and precision?

The machine utilizes the Big Plus Spindle system (CAT 40), which provides maximum rigidity through simultaneous taper and flange contact between the machine spindle and the tool holder. Additionally, the spindle features rigid tapping and is supported by an oil jacket chiller to reduce thermal effects.

What is the benefit of the Adaptive Feedrate Control (AFC) system?

Adaptive Feedrate Control enables the Machining Center to monitor the amount of spindle load a tool is generating during a cut, and then increase or decrease the programmed feedrate to compensate. It is useful for minimizing wasted cycle time by detecting air cutting and will trigger a "Feed Hold" condition if a catastrophic tool failure or severe axis overload occurs.
