High performance meets productivity

This machine solution is available as AM3 and AM4 in two sizes. The core of this system solution is a hydrostatic rotary quill. A permanently assigned spindle row is responsible for each work step.

Perfection in the high-performance segment of connecting rod machining

With its impressive production output and flexibility, the AM offers the best values and conditions for connecting rod machining.The production module is thus positioning itself as a decisive success factor in the production output segment of 500,000 to 1,300,000 connecting rods per year.

Success factors

  • High productivity and flexibility
  • Secure access and good visibility
  • Reduced footprint compared to machines from other market players
  • Favorable temperature behavior
  • Optimization of chip disposal
  • Lower energy consumption, less wear and tear
  • Machining with retracted Z-axis for maximum precision
  • Save time during set-up and changeover

Machine principle

A dedicated spindle row for each processing step – that is the AM machine principle.

A tool change is not necessary, tool change times are eliminated. The advantages of this concept: high productivity and low energy consumption.AST’s many years of expertise in connecting rod machining come to bear in the individual process design. In this way, the performance potential of the machine can be fully exploited.

All processing steps in one clamping

In the AM, tool spindles can be mounted on two sides and on the ceiling of the machining area. This makes it possible to carry out pre-machining and screw hole machining or complete finish machining in a single clamping operation – and with optimized installation space.In contrast to a machining center, the AM does not require a tool change during operation. The chip-to-chip time is less than one second with stacked rows of spindles.

Hydrostatic round sleeve

Maximum solidity in the production process

The core of the AM series is its hydrostatic rotary quill. It is characterized by its high rigidity and integrates the feed movement in the Z-axis with the rotary movement in the C-axis. Compared to the parallel linear guides used in the past, which are preloaded due to their static overdetermination and are therefore subject to wear, the round sleeve has the advantage that it practically does not wear and cannot move.

The oil film of the hydrostatic quill bearing ensures a high level of damping of the process and decoupling of workpiece vibrations and machine.
