Contourbreton NC260K23 NEW! Don’t miss this opportunity

Contourbreton NC260K23 NEW!

Major Components
- Basement including work bench and lateral shoulders for the bridge sliding, inside which are housed the guides, protected by bellows. The machine is equipped with a tank for wastewater collection and channelling.
- Spindle bridge housing the ground guides, protected by bellows, for the spindle-holding carriage sliding. The movement is by means of a digital brushless motor.
- Spindle carriage, made of iron casting and sliding on recirculating roller runner blocks ("X" axis) by means of a brushless motor. The spindle-holding ram ("Z" axis) slides vertically inside the carriage on recirculating roller runner blocks, driven by a ball screw / preloaded nut assembly which is powered by a digital brushless motor.
- Electrospindle with HSK-B80 tool-holder, cooled by electric refrigerator and provided with a middle duct to let the tool cooling water and taper cleaning air pass through.

- Grooved aluminium work bench for vacuum cup locking, fixed to the basement.
- 36-cell automatic tool magazine composed of two opposed, linear and lateral 18-cell tool magazines.
- Full protection system consisting of frontal protections with manual opening, con-forming to the CE standards.
- Siemens 840SL computer numerical control (CNC), capable of interpolating 3 axes, with optimization of the paths.
- Control monitor equipped with keyboard to enter the CNC data and including all the con-trols required to control both the machine and its accessories.
- Electric control cabinet
- Spindle inclination from 0 to +3°   
The spindle positioning and its hydraulic locking in place are carried out automati-cally in accordance with the preset work cycle program, while the desired inclination is selected activating manually the adjuster, which is installed next to the spindle.

- 4th C-axis for the continuous interpolated cut using a saw blade. This accessory makes it possible to use the cutting units holding a diamond saw blade and includes the prearrangement of the tool-store so as to accommodate the 90° and 60° head.

- Set of vacuum cups (H=150 mm) with mechanical lock support, complete with brackets.

- Parametric program to machine pockets with three-dimensional interpolation. This program is mainly used for the machining of kitchen tops with inclined surface.

- BretonCam PLUS 2.75 Stone CAD/CAM software
It is a powerful, user-friendly CAD/CAM software, to be installed on a PC outside the machine. The software is based on the icon programming principle and uses parametric technological macros for two-dimensional figures and to control three-dimensional surfaces. It makes it possible to draw numberless pieces with complex and sophisticated shapes through the CAD module and then prepare the work programs in a computer-aided way, processing the sequences of tools used in the various machining through the CAM module. This software simplifies the utilization of series of tools for polishing a profile. It enables to modify both the geometry of the pieces drawn and the sequence of tools used. It also allows to program dishing out machining on billets.

- Laser sensor to control the tool profile, diameter and length
with software for the NC automatic control and data storage

  1. I really love your blog.. Great colors & theme.
    Did you build this amazing site yourself?
    Please reply back as I'm hoping to create my very own
    blog and want to know where you got this from or just what the theme is called.

    Thank you!
