Coordinate drilling machine with CNC solves the problem of producing complex parts in a short time. The readjustment of the machine is facilitated, which makes it indispensable in small-scale production. Multi-axis systems make it possible to produce grooves, holes and threads in hard-to-reach areas of a workpiece in a single metal cutting cycle.
Kinds
The CNC coordinate drilling machine works both vertically and horizontally. The tool is clamped by a rotating unit of increased power - a spindle. There can be several such elements; an automatic magazine or manual method is used to change the incisors.
When rotating the workpiece, revolvers are used that have several grooves for attaching the corresponding tool. The change of incisors occurs by rotation, often up to 8 positions are used. With a stationary part, a change of position relative to the drill is made by a coordinate table having up to two axes.
The coordinate drilling machine with CNC is represented by the main models:
- Uniaxial limited functionality, designed to produce holes with sizes ranging from 18 to 50 mm in diameter. To offset the workpiece is complemented by two coordinate axes of the table.
- Vertical type systems with tool magazine or turret.
- Gantry type - applicable for processing long sheet materials.
Solid material processing
Coordinate drilling machine with CNC is used in the production of high-precision products. The performed grooves, holes, chamfers have tolerances up to thousandths of a millimeter. Volumetric surface treatment is performed by radial systems where the cutting tool is rotated relative to the workpiece.
A CNC coordinate drilling machine for metal is manufactured for mass production. The accuracy of the movement of the axes is carried out by stepper motors with a command from the servos. The system controller processes machine codes previously loaded into the device’s memory. The software comes with selected models and is available for download on the Internet.
For the manufacture of electronics
Craftsmen use a CNC coordinate-drilling machine for printed circuit boards. Own inventions do not have a proven reliability of the nodes. Ready-made models make it possible to achieve mass production by simply loading the three-dimensional model into the application. However, high accuracy of axis movement is required, which makes structures expensive compared to the chemical method of manufacturing tracks. Investments pay off with installation performance.
Devices for manufacturing boards are manufactured in small sizes, which allows them to be transported without dismantling the main components. The axle alignment is not lost, the system performance exceeds the classical methods for the release of microelectronics parts. Materials for processing can be: textolite, lavsan, fiberglass.
