Product Description

Heidenhain Control TNC 640

Our Takumi Machining Centers are equipped with the latest Heidenhein TNC control 640.

Precise High performance spindle

With the U400 + U600 Takumi offers the optimal spindle for your demands
Spindle speeds from 15.000 to 24.000 (rpm)
Output up to 14kW – 45kW
Interface: SK40 BigPlus – HSK-A63

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.
