Centro di lavoro CNC KT38 (Old)
The KT38 is a powerful 3 Axis CNC machine, designed to be the ideal stone working center.
The included program is realized to facilitate the interaction between operator and machine, especially thought for kitchen sink cutouts, it can import and work with DXF (AutoCAD) files and “G-code” ( RS-274 machine tool programming language) the program among other things shows the operator the right placement of the vacuum pods, and of the parts to work, it allows the machine to work with more tools mounted on the same tool holder, and has automatic and dynamic compensation to account for the wear of tools, so the machine will always achieve a perfect polish.
The absolute precision of the movements is guarantee by a state of art transmission on linear ball guides, moved by brushless motors through ball screws.
The servo cooled vectorial electric motor has a constant power of 70Nm (highest torque of any stone working center) and is controlled in speed and angular position from 0 to 10000 RPM, the mechanical spindle with optional high speed ceramic bearings is belt driven and has internal and external water cooling for the tools, compatible with standard ISO/BT40 tool holders.
The machine comes standard with 27 automatic tool change stations on a tool carousel optionally extendible to 108.
The machine has 4 interpolated axis X, Y (REAL gantry controlled), Z and A (Spindle position control), controlled by Aitek’s CNC online monitoring system capable of 9 axis interpolation.
The machine comes with a water centrifugal vacuum pump (LRVP) in stainless steel, made for creating vacuum without troubles even if muddy water is intrudoced in the vacuum system.
Other options include the left and right spindle group rotation; this option allows the machine to make polished drain boards for kitchen tops.
Also optional the surface probe, this option allows the machine to work parts with inconstant thickness with the polished side up.
The machine can also optionally mount a tool diameter probing laser, to automatic measure tools diameters.
The last option is the saw aggregate, this aggregate it’s an electric motor which can mount blades for cut, or grooving blades, the cutting direction of the blade is controlled by the spindle A axis available on all machines.
The machine with the optional CAM program is capable of processing complex 3D engraving jobs out of stone blocks like a basin or a bust, the machine can read G-code up to hard drive size with a maximum working speed of 6000mm/min and a precision of 0.01mm.
The machine works with standard 3D G-codes, G-codes can be generated from any commercial CAM, the machine is capable of engrave writing, doing bas-relief and so on. The only limit is the capability and the fantasy of the operator.
DIAMETER PROBE
The machine can optionally mount a tool diameter probing laser, to automatically measure tool diameters.
SAW AGGREGATE
The optional saw aggregate is an electric motor capable of mounting blades for cutting or grooving.
DOUBLE TOOLS
The machines with automatic tool change also support more than one contouring tool mounted on the same cone (only with AiTEK CAM).
THICKNESS PROBE
An optional surface probe allows the machine to work a slab with inconsistent thickness,while leaving the polished side up.
AUTOMATIC TOOL CHANGE STATIONS
The machine comes standard with 27 automatic tool change stations on a tool carousel （optionally extendable to a possible 108.）
3D ENGRAVING JOBS
Machine with the optional CAM program is capable of processing complex 3D engraving jobs out of stone blocks like a basin or a bust.
