Highlights

Automatically adapts to the cutting conditions in-process

MV automatically adjusts cutting parameters (depth of cut, feed rate, etc.) based on real-time measurements of the spindle’s power and torque.

  • Reduces cycle time
  • Increases process reliability
  • Extends insert life

When we talk about quality, every detail matters
Mv
Machine base
  • Welded metallic profile construction, guaranteeing machine stability and rigidity to meet your accuracy requirements
  • FEM validated at the design stage and proven in production
Vertical displacement unit (Z axis)
  • Welded and stabilized base column with ballscrew driven workhead mounted on linear guideways
  • Optimum axis travel for accurate machining
Boring bar/tool

High precision boring bar with robust construction to perform wheel boring operations. Highly accurate, customizable and versatile.

Self centering workholding

A non-rotary chuck for the highest precision.

  • Made of cast iron
  • 3 hydraulically actuated centering jaws
  • Chips pass through the central bore for excellent evacuation
Control panel

Located close to the machining area, giving the operator an optimal view.

Chip conveyor

The chips directed through the chucks central bore are evacuated from underneath the machine by a chip conveyor.

Customization
Configure your boring bar
  • Wide range of cutting insert geometries
  • Option to mount 2 inserts for optimum machining at greater depths

You can mount a wide range of insert geometries to obtain the best surface finish.

The machine allows chamfers or radii to be made on both the top and bottom face of the hub.

Need to machine an oil groove? No problem, the versatility of the tool used allows you to do so easily.

Automation
Automation

Automation will boost your production capacity and reduce your manpower

Is throughput a key metric for you? Automation of loading and unloading may be your solution.
