(01.06.58) Base Design and Construction
The SCM Pratix N15 C owes its rigidity to the design and weight of its reinforced base and innovative one-piece frame. All portions of the base are of heavy gauge steel and are normalized after welding, a process which ensures that all stress in the base is removed before it is machined and drilled for the guides.
Today's machining centers are being asked to perform a wide variety of operations at the highest speeds possible while, at the same time, maintaining a high quality of cut. Micro-vibrations are created around all types of CNC machining centers where there is head positioning, drilling, and high speed routing taking place on the machine base. SCM solves the problem of deadening vibration as well as offering rigidity by employing heavy gauge steel members for the base of the machine. This weight, coupled with the one-piece frame offers the best combination of rigidity and balanced strength on a bridge design. Movement along the X is high precision rack and pinion while the Y & Z-axes is driven by a ball screw.
High Precision, High Load Prismatic Bearing Guides
SCM uses prismatic guides for support in all axes. Due to their added weight load capability (approximately 4 times that of conventional round guides), prismatic type guides can permit accurate head positioning at high speeds.
A.C. Servo Motors X,Y & Z Axes
A.C. servomotors, or A.C. brushless motors as they are sometimes called, are the latest in electronic linear motion technology. A.C. servomotors use less power and produce a more even output (drive) throughout the power band. The ability to maintain a constant torque setting when going from an idle setting into a heavy rout produces cleaner cuts and longer tool life. These motors are controlled by digital supply cards that offer the reliability and precision fine tuning associated with solid state electronics.
Solid State Inverter Controls Router RPM
Solid State frequency inverters support the programmable router spindle speeds (S functions). By utilizing digital inverter technology, the programmer can select the correct cutter RPM and match it to the correct linear/rotational feed speed for the specific application and/or material being cut. This will give optimum quality of cut while greatly extending tool life. The inverter also acts as an electronic brake, stopping the router spindle motor in microseconds if an emergency signal is given.
Xilog Plus Operator Interface
XILOG PLUS is the SCMI workstation management software developed as a highly flexible, powerful and user-friendly programming system.
- The beginner will immediately find himself at ease in front of the intuitive XILOG PLUS interface. There are many graphic aids that eliminate the need to learn particular instructions or programming language.
- The more experienced computer user will also find himself at ease in a Windows® based operating environment, including all the features that this implies (i.e., cut and paste, multiple opening of files, etc.).
- Those already familiar with previous SCMI programs will be able to choose whether to manage the machine in the new graphic environment or to continue with the traditional input of programming instructions with the alphanumeric keyboard. Moving quickly from one environment to the other is very simple.
XILOG PLUS has two applications – to aid in programming and to allow operation of the machine.
Graphic programming interface
This application is a powerful graphic/text editor that aids in programming. It manages program file as well as tooling information. Especially helpful are the built-in macros, shortcuts that are used in performing repetitive tasks (routing arcs, drilling shelf holes, etc.). Users can also customize macros for their own particular needs.
Machine Operation Interface:
This application allows the operator to recall programs and run them on the machine. It tells the operator basic information about the program such as the working field, part size, etc. It also has a very powerful machine diagnostic section with photos and troubleshooting aids.
Additional XILOG PLUS features:
- Controlled acceleration and deceleration
- Linear and circular interpolation
- Self diagnostics through error messages
- Dynamic tool correction via PLC due to active wear concerning space and time.
- Subroutine programming (canned cycle) with library
- Specular programming: Allows writing of programs two different multiple reference points. For example the Left or Right corner of a panel.
- Parametric scaling of programs through use of template type programs that the operator creates and stores in memory. Part programs can then be proportionally scaled up or down in size without the need to re-write the entire program.
- Programs can be viewed from all 5 faces
- Built in macros for simple, widely used programs
- On board cycle optimization

Aluminum Solid worktable for Component Nesting
The aluminum multi-function worktable has an answer to most component nesting scenarios. The table is designed of high tensile strength aircraft aluminum, and is slotted both transversely and longitudinally to accept many different fixturing devices.
4 Left stops for "A" field of which no. 1 Side Stop and no. 3 Rear Stops
In addition to nesting full sheets, the Pratix N15 C can also be used for routing smaller components. For work on the face of the component, rubber gasketing material can be used to isolate the vacuum for part hold-down. This eliminates the need for special fixturing devices as is necessary on many machines. When machining the edges of parts, the patented MODULSET system raises the component so work can take place without damage to the worktable.
The magnetic system for opening and closing the vacuum passages allows for an extremely quick table set up when the vacuum is only required in a portion of the table. With a dedicated tool (supplied) it is a matter of seconds to perform the set up with no need for a screw driver. PATENTED
8 Vacuum Areas Controlled By Electronic Switches
Automatic Unloading System
The Pratix N15 C NBR is equipped with an automatic unloading system which cleans dust from the top and the bottom while removing the machined material from the machine. Using this system the operator is able to load the next sheet without wasting time on cleaning the machine table.
This system can be supplied with an additional feature capable of completely clearing the machine area by pushing the material to an external table. This operation is performed while the machine is being loaded or even while it is already working again. This system allows for the stacking of the components to be performed in a completely masked time. The off loading table is not included with the machine.
Dust Outlet – (1) 200mm (1) 150mm
Central Optimized Dust Collection System
It provides a single dust collection point for the electrospindle and Drilling unit allowing in this way to use the Dust Collection system more efficiently. Inside the main dust collector there are pneumatic cylinders that control automatically the opening/closing of each exhaust outlet when the operating unit is switched on/off.
Dust Outlet – (1) 200mm
Automatic Central Lube System
The correct amount of grease is applied to lubricate moving parts on the machine. This is applied automatically with minimal maintenance for the operator.
Autotransformer allows the choice of 208 / 230 or 460 volt, 3-phase, 60 cycle
Two (2) 300 Cubic Meter/Hour Vacuum Pump
The vacuum hold-down system features a 300 cubic meter/hour vacuum pumps. It offers the reliability of a substantial increase in vacuum power and allows the use of spoil boards for nesting full sheets.
Photo Cells and Protective Cage
The SCM Pratix N15 C is equipped with photocells and a safety fence. This system includes barriers on three sides of the machine combined with photocells on the front side, which allows access to the work area.
The photocells stop the work cycle in the operational field of the machine; the barriers prevent physical access to the machine. This system is called active because it prevents any contact between the moving parts of the machine and the operator.
