Product Description
Heidenhain Control TNC 640
- Our Takumi Machining Centers are equipped with the latest Heidenhein TNC control.
Precise High performance spindle
- With the U400 + U600 Takumi offers the optimal spindle for your demands
- Spindle speedsfrom 12.000 to 15.000 (rpm)
- Output upto 10kW – 30kW
- Interface: HSK63-A / SK40 - BigPlus / BBT40 / HSK100-A
Extremely stiff and high-presision mechanical structure
- The load-bearing mechanical structures such as bed, pillar, bed sledge are made of heat-treated and stress-released Meehanite cast iron. The thereby gained absorption capacity enables low-vibration machining processes. This ensures high surface quality on the workpiece and increases the tool life.
- Portal construction and stepped column for maximum rigidity, optimized force flow, minimization of the spindle overhang and increased dynamics
- Three-plybed
Mechnical accuracy
In order to increase the durability of wear parts, Takumi pursues the philosophy of generating geometric accuracy from mechanics. The greatest effort is put into assembling the machine, for example, contact surfaces are hand scraped. Components are aligned to each other with the highest precision and assembled with the utmost care. Subsequent compensation via the machine control is thus reduced to a necessary minimum.
Thermal stability
In order to be able to offer you a perfect tool for your high-precision production, the following measures have been consistently implemented in the U- series :
- Core-cooled and pre-tensioned ball-screws.
- Thermal compensation of the spindle expansion including sensors.
- Jacket-cooled milling spindle.
- Linear scales.
Reliable results
Quality components from well-known manufacturers guarantee durability and achieve the desired results:
- Oversized high-precision roller linear guides in all 3 axes.
- Pre-tensionedball screws to absorb thermal deformation and maintain maximum accuracy.
- 6 or more guide blocks per axis generate a balanced performance between dynamics and accuracy
Dynamics
- Moving mechanical elements are inherently stiff and reduced in mass.
- The high-precision roller linear guides ensure a quick response when accelerating and decelerating, resulting in high dynamics. Due to the large contact surfaces, they also ensure optimal load distribution on the guideways. The load capacity and torsional stiffness of the individual axes are increased to a maximum.This reduces the wear on the guides and also compensates vibrations during high cutting forces.
- The optimal number and positioning of the guide blocks reinforces the rigidity and ensures constant accuracy during long-term operation.
Loading
- The loading accesses of the Takumi U-machines are designed extremely generous. Both loading large components by crane and short set up times for smaller components run smoothly based on the interference-free design
Ergonomics
- Centralized maintenance units and easy-to-use work and operator interfaces generate a smooth set-up and production process.
Chip Management
Measures such as:
specifically positioned coolant flushing systems, steeply inclined inner walls, hinge or optional scraper belt conveyors, wide-open drop holes, tempered screw-conveyors effectively and reliably remove the volume and heat of the chips from the machining area.
Integrated oil skimmer
- The oil skimmer prevents the emulsion quality from tipping over, even when the temperature is high or fluctuates strongly . The life of the coolant is effectively increased.
Chip Management
Measures such as:
specifically positioned coolant flushing systems, steeply inclined inner walls, hinge or optional scraper belt conveyors, wide-open drop holes, tempered screw-conveyors effectively and reliably remove the volume and heat of the chips from the machining area.
