CNC Machining Center with Gantry Structure - ROVER J FT
As guarantee of the quality of its products and services, BIESSE has been certified ISO 9001 since 1995 and works in accordance with the UNI EN ISO 9001:2000 norms.Most of the technological components assembled on the machining centres is produced by companies of the Biesse Group or by world-wide known companies included in the Biesse "Register of Qualified Suppliers", which have strictly cooperated with Biesse through the years.The running tests of each machining centre include the following stages: Intermediate control of operating units and pre-assembled components Non-stop running test as machining simulation for a minimum period of 10 hours Control of X and Y axes precision and positioning repeatability by means of an interferometric laser (VDI/3441 norm)
Gauging of the X and Y axes through a software function: the values detected during the laser tests are elaborated by the N.C. and transmitted to the axes drives in order to improve the positioning precision Functional tests for routing and boring operations on panels positioned on all the machine origins
Main frame and mobile upright beam
The machine frame is made of thick electrowelded steel sheets, properly strengthened in the most stressed areas.The upright beam, mobile in the longitudinal direction (X axis) is made of electrowelded steel with gantry structure: thick steel sheets and reinforcing transversal elements allow to minimize the twists generated by the materialstress relief generated by the metal machining and obtain the highest levels of precision.
Axes movement
Axes drives and motor systemsBiesse uses Brushless motors, controlled by digital axes drives.The interfacing between axes drives and numerical control is digital.The digital system Mechatrolink allows the following: Higher machining speed, since a portion of the toolpath is controlled by the axis drive instead of the numerical control Higher working precision, thanks to a faster data processing Higher reliability, thanks to a reduced wiring system which eliminates electrical interferences that may occur on analog systems
X and Y axes transmission
The operating unit moves along the longitudinal axis (X axis) and transversal axis (Y axis) by rack and pinion system (a solution that BIESSE is been using for twenty years) which grants high acceleration and movement speed.Both rack and pinions are built in accuracy class 6 (DIN 3962 norm).The mobile upright beam has two independent drives, one on each side.Z axis transmissionAs the operating unit moves in the vertical direction (Z axis) with a relatively short travel, BIESSE uses the ballscrew system with preloaded nut for backlash compensation and repeatability in positioning precision. The movement is transmitted to the screw through a flexible joint.The ball screws are in T7 accuracy class.
Axes guides
A couple of linear guides with recirculating balls running block is located on every axis to ensure an high level of precision and smoothness of each movement.Manual lubricationCentralized manual lubrication system for the main movements: X axis: 4 running blocks of the linear guides and 2 for the racks (1 on each side of the machine) Y axis: 4 running blocks of the linear guides and 1 for the rack Z axis: 4 running blocks of the linear guides and 1 for the ball screw nut
