Overhauled and guaranteed Intermac Master EDGE workstation

DESCRIPTION

DISTINCTIVE CHARACTERISTICS

Numerical Control workstation with three axis, Intermac Master Edge 1500, for milling, drilling and grinding glass sheets.

MECHANICAL STRUCTURE

Composed by gantry axis, it is manufactured with electro-welded steel elements, properly ribbed and normalized, it ensures the stiffness needed for the warranty of performance over time.

The machine’s weight, 6tons, is the essential element of solidity.

3250x1620mm WORKTABLE

It allows multiple placements. It is covered with synthetic material and the same operating head rectifies it for a perfect planarity.

The machine is provided with a placement system and it holds work pieces through suction cups equipped with a dual vacuum circuit, which allows a simple and quick positioning without the need for mechanical fastening. The vacuum system supplies suction cups, which hold work pieces with a liquid ring vacuum pump of 75 m³/hour and it doesn’t need any maintenance, with a management system divided in two separate areas.

Fittings for suction cups, at the front of the machine, with quick couplings. Water collection and refrigeration system with 2 full extractable basins of 0.5 m³, placed under the worktable.

Maximum size of the workable piece: 3000x1550mm

N. 2 AUTOMATIC AND ROTATING TOOL CHANGERS WITH 28 POSITIONS

They are positioned on both sides of the machine, allowing the reduction of time for tool changes. Automatic verification of the tool presence before the discharge phase.

ELECTROSPINDLE

10HP power with vector control of the rotation from 0 to 15000 rpm. Provided with a double refrigeration system: inner system of water, cleaned directly from the tool inside . Device with quick fittings for tools like ISO 40 attachment with a mechanical locking system through cup grinding wheels and an unlocking system with a pneumatic cylinder with a 7 bar working pressure. Automatic cleaning of the cones during the tool-changing phase with a compressed air injection directly on the cones.

Pressurization pneumatic circuit against polluting substances.

10 OSAI SERIES NUMERICAL CONTROL

Main characteristics:

Interactive operating panel with color liquid crystal monitor like 10” TFT with 800x600 pixels

Alphanumeric keyboard

Integrated PLC;

3.5” floppy disk;

Ethernet interface

Self-diagnosis and machine downtime statistic

Oscilloscope

Automatic compensation program polishing wheels’ wear with 300 Hz working pressure reading:

Program for the automatic reduction of progress according to the tool thrust.

AXIS DISPLACEMENT

Obtained through digital brushless motors and with a ball screw and balls recirculation. Pretensioned screw, strictly sealed to the structure. Screws and guides are mechanically protected and equipped with an automatic lubrication system.

TELESERVICE

CNC is suitable for the Teleservice function, which allows accomplishing:

Remote diagnostics and troubleshooting.

Software and machine’s parameters update.

Elimination of errors in spare parts search.

CHARACTERISTICS OF THE TYPE OF REVISION

The machine, year of construction 2004, is secondhand and it is completely overhauled. A more precise description of future workings will be shown below.

STRUCTURE REVISION

The iron structure will be sandblasted in all the areas that have been possibly damaged by the rusting process or with remaining glass powder. These areas will be plastered and then the structure will be completely repainted with its original colors. All this will be done after the removal of mechanical, electrical and pneumatic installations.

REVISION OF THE MECHANICAL INSTALLATION

Mechanically, every timing belts will be replaced but also support sliding blocks and sliding movements of the carriage (X Axis), the bridge (Y Axis), the head (Z Axis).

The backlashes will be verified and eliminated on the balls recirculation, which are actually in charge of the movements; finally, the fastening bushings of the tool changers will be overhauled too. Replacement of the PVC worktable.

REVISION OF THE ELECTRICAL INSTALLATION

Substitution of worn connection cables between the electric panel and various mechanisms (motors, solenoid valves, sensors) with verification of the water pump and the vacuum pump operation.

Electric panel placement, verification of the OSAI S10 CN functionalities.

REVISION OF THE HYDROPNEUMATIC INSTALLATION

Complete replacement of all the water and pneumatic system pipes with substitution of the taps where suction cups pipes are inserted, but also reference fences and glass holding.
