VM Series – Ram Type Turn-mill Centers

The VM series of machines are best suited for heavy material removal and accurate machining of large components, configured with RAM in either fixed or moving cross rails.

These three-axes machines are available in fixed cross rail and moving cross rail configurations. Machines are with a rigid ram and a 12/24 tool umbrella-type automatic tool changer (ATC) that can carry heavy tools and make the machines more versatile. In addition to the standard operations of turning, facing and boring, the VM series can also perform milling, drilling, reaming, and tapping, among others. The machines can also be altered to various configurations to meet unique customer requirements.

The cast-iron cross slide and cross rail enhance productivity and component accuracy. Assembled with larger-sized linear motion roller guideways for the X-axis, the machines deliver remarkable precision and repeatability in axis movement. The centralized automatic grease lubrication eliminates coolant contamination and minimizes wastage and environmental impact. The live tool with the C-axis can interpolate to generate profiles.

This VM series of machines also boasts rigid tool holding with a BT50 spindle adapter, which provides optimal power for the tool. We also offer a high-pressure spindle thru coolant and helical interpolation facility as options. Machines are provided with a table type of work spindle with high precision taper roller bearing and thrust roller bearing for the table.

The model has WIDMA’s standard safety features such as the pressure switch for hydraulic chuck and hydraulic counterbalance, the operator and maintenance door interlock, tier switch for monitoring lubricant and coolant level within the tank, a pressure switch for monitoring compressed gas supply pressure, and a tool management program built into the CNC.

We can also customize this machine with additional remote diagnostic capabilities for CNC controllers, which provide access to the controller data from any remote location, making it easier to report and address concerns with minimum machine downtime.
