SCM SI 400 EP Panel Saw
The SCM SI 400 EP is a sliding table panel saw designed and manufactured by SCM Group, a leading Italian woodworking machinery company. Positioned within SCM's "Class" range of machinery, the SI 400 EP represents the company's dedication to providing "classical machines for the advanced joinery" sector. This model combines robust construction, precision engineering, and advanced electronic controls to deliver superior cutting performance for professional woodworking operations.
The SI 400 EP is classified as a programmable circular saw, distinguishing it from the manual models in the SCM lineup. It features the "EP" designation, which indicates its enhanced electronic programming capabilities compared to standard models. With its 400mm maximum blade diameter, the machine offers substantial cutting capacity while maintaining precise control over complex operations.
According to SCM's product documentation, the SI 400 EP embodies "superior technology combined with an ease of use," making it suitable for a wide range of woodworking applications from precise joinery to panel processing. The machine is designed for professional cabinet shops, furniture manufacturers, and advanced woodworking facilities where both quality and productivity are essential requirements.
The SI 400 EP is available with multiple control system options, including the standard "READY" electronic control and the more advanced "eye-S" touchscreen interface. These control systems allow for programmable management of cutting operations with varying degrees of automation, from basic electronic positioning assistance to comprehensive digital workflow management.
As described by Daltons Wadkin, an authorized distributor, the SI 400 EP is part of SCM's commitment to guaranteeing "customers high quality technologies which meet their requirements in such a way as to make SCM the partner for any needs." This philosophy is evident in the machine's construction quality, technological features, and versatile configuration options.
The machine is built on a heavy-duty cast iron structure with an innovative sliding carriage system that uses "arch-ground steel slideways" – a proprietary SCM solution that ensures exceptional cutting precision and long-term reliability. This design allows for a guaranteed straightness tolerance of ±0.05mm over the entire carriage length, contributing to the machine's reputation for consistent, high-quality cutting results.
In the hierarchy of SCM's sliding table saw offerings, the SI 400 EP sits between the entry-level Nova series and the top-tier "L'invincibile" professional machines, offering a balance of advanced features and value for professional woodworking operations.
Technical Specifications
Blade and Cutting Specifications
The SI 400 EP accommodates a maximum saw blade diameter of 400mm when equipped with the mounted scoring unit. This substantial blade size enables a maximum cutting depth of 140mm at 90° and 97mm at 45°, providing excellent versatility for both panel processing and solid timber dimensioning. The machine features variable blade rotation speeds of 3000/4000/5000 rpm, allowing operators to optimize cutting parameters based on material type and cutting requirements.
The scoring unit, which is essential for clean cuts in laminated panels, is powered by a dedicated 1.2 HP motor that ensures precise scoring operations. According to the technical documentation, the machine offers an option for a two-axis scoring unit adjustment system that provides programmable control of the scoring blade position.
Table and Carriage System
One of the defining features of the SI 400 EP is its precision-engineered sliding carriage system. The machine offers squaring stroke options ranging from 2200mm to 3800mm, with the standard configuration typically providing a 3200mm stroke. The sliding carriage employs SCM's proprietary "arch-ground steel slideways" design, which guarantees a straightness tolerance of ±0.05mm over the entire carriage length.
The cast iron saw table measures 1040 x 630mm, providing a stable and durable work surface. The sliding table features a "closed reticular geometry with steel guides" that never requires adjustment, ensuring long-term reliability and cutting precision.
Rip Capacity and Fence System
The SI 400 EP offers adjustable cutting width on the rip fence ranging from 1000mm to 1500mm, with various options available depending on specific customer requirements. The standard configuration typically provides a 1270mm rip capacity. In more advanced configurations, the rip fence can be motorized with programmable positioning, riding on a "recirculating ball screw mechanism with sliding on linear guides" for smooth and precise movement.
The squaring frame and fence system allow for panels measuring up to 3200 x 3200mm to be accurately squared. The telescopic squaring fence includes an inclined metric scale and two reversible stops for precise positioning.
Power and Motor Specifications
The SI 400 EP comes standard with a 7 kW (9.5 HP) three-phase motor at 50 Hz (8 kW at 60 Hz), providing substantial power for demanding cutting operations. An optional upgrade to a 9 kW (12 HP) motor is available for applications requiring additional cutting power. The machine features automatic star-delta starting for smooth power delivery and motor protection.
The optional motorized components, including the powered rise/fall and tilt adjustments, are controlled via the electronic control system, which varies depending on the specific configuration ordered.
Dust Extraction Requirements
For efficient dust management, the SI 400 EP is equipped with multiple dust extraction outlets. According to the technical documentation, these include:
Proper dust extraction is essential for maintaining clean cuts and a safe working environment, with the machine's design optimizing airflow for effective dust removal.
Control System Options
The SI 400 EP is available with several control system configurations, each offering different levels of automation and programming capabilities:
"READY" Version: Features powered blade height/tilt adjustment, tool data setting with auto height adjustment, 99 program memory capacity, calculator, and hour counter.
"READY 3" Version: Adds a powered rip fence with digital readout of rip fence position, and includes start/stop controls on the sliding table.
"READY 3 UP" Version: Incorporates an upper 'eye-level' control panel for improved ergonomics and accessibility.
"READY 3 UP PLUS" Version: Features an upper 'eye-level' 7" colour touchscreen control, powered rip fence with digital readout, extended cutting width of 1500mm, and 300 program memory capacity.
"eye-S" Console: The most advanced option featuring a 10" colour touchscreen display with the Maestro active user interface, providing enhanced visualization and intuitive programming of cutting operations.
Dimensions and Weight
While specific dimensions vary based on the chosen configuration, particularly the carriage length and rip capacity, the SI 400 EP represents a substantial piece of machinery that requires adequate shop space for safe operation and material handling. The comprehensive technical documentation provides detailed dimensional drawings to assist with installation planning.
Connectivity and Industry 4.0 Capabilities
The advanced electronic control options for the SI 400 EP include connectivity features for Industry 4.0 integration. These capabilities include:
Connectivity among machines belonging to the same company network
Sharing of work programs and tools database
Activity monitoring and reporting on machine usage
Connectivity with SCM Thundercut (optimizer/sequencer App)
Self-diagnosis, tele-service and troubleshooting links
These specifications collectively define the SCM SI 400 EP as a versatile and capable sliding table panel saw suitable for a wide range of professional woodworking applications, from precision joinery to high-volume panel processing.
