a40 SE

Higher performance in aluminium die casting components

Higher performance in aluminium die casting components
Introducing the Makino a40 SE, the new generation of horizontal machining centres designed and built to address the challenges of die cast parts production. The aim of the updated a40 is to further increase the performance of aluminium die-casting machinists by increasing the autonomy and performance of the existing a40. On the one hand, the machine is prepared to use hydraulic fixtures which mean it is totally prepared for automation, while the increased ATC size will assure non-stop production. On the other hand, the increased spindle speed of up to 20,000 rpm will enable smaller tools and PCD tools to be used in the machining process.

Productivity

Productivity
Makino understands that one of the largest drivers of cost per piece is the cycle time. Cycle time drives the number of machines required but also has far reaching cost implications affecting labor, floor space, utilities
and durable tooling. The a40 SE features Makino’s Intelligent R.O.I. design, a collection of innovative technologies designed to slash unproductive non cut times from your part process.
 
  • Responsive HSK-A63 spindle accelerates to 20,000 rpm in 1.5 seconds.
  • Quickly complete common tapping operations with the 6,000 rpm rigid tapping synchronization speed.
  • Minimize feature-to-feature positioning time with linear axis that reach full rapid traverse rates, thereby achieving an average up to 30% faster than similar machines in the market.
  • Inertia Active Control (IAC) evaluates fixture and tool weights to optimize acceleration performance of multiple machine systems.

Reliability

Reliability
Reliability of your machining system is a paramount consideration. The a40 SE leverages on robust, proven systems like single piece X and Z axis covers, center trough chip / coolant management and dual supported
ATC mechanisms from Makino’s 1-Series horizontal machining centres. New and improved systems ensures reliable operation.
 
Vision B.T.S.
  • Tool breakage detection function by camera

  • Quickly checks the status of the tool before and after tool change

Taper cleaning coolant feature
  • Cleaning achieved by coolant with 20 μm filtration accuracy at the time of tool exchange

  • Ensures no chip on tool clamping

Coolant filtration system
  • 20 μm filtration accuracy achieved by three stages of the cyclone filter

  • Sludge associated with the aluminium machining is removed

  • Reduce the frequency of preventive maintenance and cleaningof the coolant tank

Spindle

Spindle
The a40 SE's spindle is designed to address the specific challenges of die cast parts production. Its responsive direct drive design accelerates to 20,000 rpm in just 1.5 seconds providing the reliability of a HSK-A63 with the performance advantages typical associated with 30 taper drill tap solutions.

The new improved a40 SE spindle allow us now to use cutting tools which requires high rpm for the machining, such as PCD end mills, PCD face mills and small size drills.
 
Rigid Tapping Synchronization Up To 6,000 rpm
Fast spindle acc/dec reduces tapping times per hole by 0.5 to 0.7 sec
compared to typical 400 mm HMC solutions.
