Itech Plast has just acquired a Makino make F Series Vertical Machining Centre with high accuracy for the tool & die making industry. Repeatability & accuracy of the machine across the stroke will be +/- 0.0025mm. Machine is equipped with ATC for fast tool change & through coolant spindle for high accuracy of make a new tool to satisfy customer’s precision accuracy expectation.
Makino make F Series vertical machining centers are designed to provide stiffness and rigidity for chatter-free cutting, agility for high-speed/hard-milling and accuracies for tight-tolerance blends and matches typical of complex, 3-D contoured geometry associated with die/mold and medical production.
This technology advancement will strengthen iTech Plast’s commitment in superior quality and precision plastic parts manufacturing, for which they are known in industry.
following are some of the main advantages of Makino make F Series Vertical Machining Centre:
- Low Spindle Vibration, excellent surface finishing with long cutter R0.5mm length over diameter ration equal to 10.
- Achieving close tolerance on multi-facet geometry
- Small rib and slot machining
- Direct Machining on hardened material with length over diameter ration equal to 7, achieving good dimensional accuracy.
- Excellent surface finish and profile accuracy with smallest cutter used R0.2m ball end mill.
Structure:
F-Series maintains a highly rigid mechanical structure and is ideal for precision die mold machining. It provides twice the mechanical structure rigidity compared to previous design.
Wider column to bed contact area provides efficient cutting force transfer. The X & Z axis motion system support does not have any overhang and maintains a constant workload.
The F-Series mechanical structure is symmetrically designed to achieve better thermal stability. The table is mounted on the Y axis to give further enhance structure symmetry.
Spindle Design and Configuration:
The key to high-speed machining is the spindle, which constitutes the essence of a machining center. Makino’s unique spindle technology is renowned and field proven over the years for it’s accuracy and reliability in the high speed machining application.
The 12,000 min spindle is supported by four angular contact hybrid bearings at the spindle front which provide enormous rigidity and superior heavy-cutting performance. Equipped with jacket cooling, the thermal growth of the spindle is kept controlled by a 2,600 kcal/h heat dissipating chiller which flows at a rate of 25L/min to remove the heat from the spindle bearings.
Motion Control:
To ensure the best results, a good controller and software is required. The F3 and F5 utilize the Makino Pro 5 Controller with the GI.3 combined with Super Geometric Intelligence (SGI.4) software for fine motion control even at a high feedrate as a standard. This control technology is developed specifically for high feedrate, tight tolerance machining of complex, 3D-contoured shapes involving continuous tiny block of NC data.
Operating ease has been enhanced by adopting Windows-like display screens and a touch-panel.
A “data center function” is also provided as a standard feature for centralized management of various types of data. Improved network functionality makes it possible to transfer and edit files in a PC-like manner.
