AUTOMATIC VERTICAL 5 AXIS DRILLING MACHINE FOR DRILLING AND COUNTERSINKING STRAIGHT FLAT SHEET GLASS
DRILL 101 is a numeric control 5 axis drilling machine designed for producing holes and countersinks of any type on straight flat sheet glass with thicknesses of 4 to 20 mm.
The machine is composed of six interpolated axes, X Y V Z W, and two electrospindles positioned opposite one another creating a dead centre system that drills perfect holes.
DRILL 101 has an entrance support, a central body and an exit support. The central unit supports two electrospindles of 3 Kw with a speed of 0 to 6,000 mounted on ball bearing guides and command racks which can move vertically or horizontally in order to carry out any process via numerical control and interpolated with Vacuum-operated belts.
Every spindle has a 8 automatic change tool slots and, through the rotating joint, allows water to cool down the system during the process, starting from the moment the sheet glass is fixed with the entrance vacuum belt. The vacuum belts steadily slide the sheet glass towards the machining centre until it reaches the correct position. Having already automatically loaded the tools required, the machine is ready to use.
Once the process is complete the sheet glass is automatically transported through the exit by the rollers to the unloading position while the vacuum belts are already loading another slab.
The vertical processing of sheet glass has many advantages in comparison with flat processing. The size of the machine is considerably less than a corresponding flat machine and the position of the sheet glass on the roller automatically obtains the fixed zero point without error to the extent that the stroke is certain. Furthermore, horizontal machines must be perfectly even to avoid breaking the glass whereas with vertical machines, the position of the glass is naturally aligned since it is supported from underneath.
The machine can carry out multiple processes:
DRILLING: thanks to opposed heads, drilling is performed with maximum speed and always guarantees optimum quality and precision.
COUNTERSINKING: it can be carried out with single diamond tools controlled from the program according to the needs of the client as well as with accessories mounted on the diamond drill bits.
The Windows XP Embedded operating system used on the state of the art numerical control makes the machine easy to use, even for less experienced operators.
The program which the operator uses for processing allows complete control of all work parameters, settings, and tool details.
By using the special functionality of the software, it is possible to safely and simply create a series of numerically controlled pre-set designs and processing types.
The automatic lubrication system is composed of numerous lubrication points situated in the areas of most movement. A central pump regulates the continuous flow of lubrication fluid.
The constant lubrication of all moving components such as bearings, recirculating ball screws and areas of linear movement is very important to prevent malfunctions and blockages and to reduce recurring maintenance costs. The central unit reaches the lubrication points of the main line according to the quantity and frequency programmed by the operator. The entire system is controlled by the PLC and is therefore managed completely automatically.
This system is composed by some supports, software solutions and special pressers that allow the milling operations.
This operation is simple and quickly and, thanks to multiple tools, the machine can mill and grind an insert in just a few seconds.
With this system the electrical spindles are ISO 40 with 4kW and 12.000 r.p.m.
