Vitap | KAIROS CNC Machining Center
CNC MACHINING CENTER
Vitap uses 3-dimensional solid modeling systems to design its working centers which are built with a mobile beam and stationary basement. The beam moves in a longitudinal direction with respect to the basement (X axis) and supports a pair of carriages which determine the movement of the Y and Z axes. The X and Y axes define a plane parallel to the floor and the Z axis moves up and down perpendicular to this plane. This configuration allows a remarkable reduction in the machine’s overall size and improves the machine’s performance and functionality.The basement and the beam are made of electrically welded steel and are ribbed and strengthened internally to guarantee maximum rigidity even under intense working.The structures undergo a thermally-controlled normalization cycle.
QUALITY CONTROL
All phases of assembly undergo conformity checks according to special testing procedures. The alignment of all the linear guides is carried out using an electronic level guaranteeing straightness and parallelism tolerances to be within 0.02 mm per linear meter. On all machines, positioning precision and bi-directional repeatability of the axes is checked using an interferometer laser system. Bi-directional positioning precision is guaranteed within a tolerance of ±0.05 mm. An electrical test of the whole system is carried out on each machine according to CEI EN 60204-1 legislation.
LINEAR MOTION SYSTEMS
The X axis movement is obtained throught the use of a single gripper system. The system is composed of one gripper driven by a brushless motor. The use of a single clamp is also used in the case of a smaller piece where the use of two grippers is not feasible. The Movement of the gripper in the X and the carriage in the Y axis are by brushless motors driving eplcyclic reduction gear, rack and pinion with a high degree of precision. The mobile beam or carriage moves on high precision pre-loaded ball runner blocks and linear guides made of rectified and hardened steel. Ball runner blocks for all axis are equipped with a seal guaranteeing maximum protection from dirt and dust.
Z AXIS - The carriages for this axis is made from an aluminum alloy with highly rigid mechanical properties. Movement of theaxis is by ball nut with pre-loaded lead screw in order to guarantee high speeds with minimal wear.The carriage is mounted on pre-loaded ball runner blocks which slide on very high precision linear guides made of rectified and hardened steel. Z axis motor and ball screws are sized to avoid the need for pneumatic assistance. All axes are driven by AC brushless motor fed and controlled by digital drives.
DUST EXTRACTION
The KAIROS uses three strategically located dust extraction ports to evacuate dust and debries away from the machining area to help maximize efficiency and maintain surface quality of the piece.
LUBRICATION
The machine is equipped with automatic Centralized 22 Point lubrication system with progressive distribution. The system has a single feeding point for the group of distributors, which send automatically and safely, an adequate volume of lubrication to each lubrication point. The system is fed with a cartridge-doser that utilizes a 2Kg grease cartridge LIKO EPO.
MACHINE SAFETY
The machine is self contained and all working units are shielded from the operator from all four sides. Additional safety systems: push buttons for emergency stop, software and hardware to monitor the safety distance, check sensors for the air level.
ELECTRICAL CABINET
The electrical cabinet is integrated in the right hand side of the machine base and is tested according to the strict international regulations (EN 60204).
TELE-SERVICE VIA INTERNET
Allows remote connection between the machine’s PC and Casadei-Busellato’s Authorized Service Center allowing direct intervention on the control for checking parameters of the whole machine, single programs and installation of eventual software updates. Internet access and connection is the responsibility of the customer.
