RMC SL

RMC SL is the most stable machining center CNC with movable carriage of its category. It is the machine, which answer most effectively to the most challenging requirements of companies processing extrusions.
The fully interpolating axes allow optimal finishing degrees and processing speeds far above the average.

It is available with 4 or 5 controlled axes, it is fully automatic and it performs drilling, milling and rigid tapping. The machine is available in three standard versions, according to the X axis travelling capacity: 4.400-6.700-9.000 mm.

The working area may be used exploiting the entire length of the machinery (single zone mode), or two independent zones (commuting mode). The machining center RMC SL is equipped with a remote assistance system on IP network.

CLAMPS

The number of the clamps depends on the length of the machine and on the machining requests. Their positioning is performed by the movable carriage, with preset by the operating program quotes. In single-zone mode clamps travel along the entire working area (field in X).

The independent closing of the clamps can be controlled during the charge of the parts.

ELECTROSPINDLE

The 12 kW S6 electrospindle with high torque allows the execution of hard processing which are typical of the industry. The spindle is cooled with a fluid system, which allows its use for steel extrusions and for aluminum profiles. The tool is lubricated with a minimal oil diffusion system which is directly controlled by the numerical control.

TOOL STORAGE

The tool magazine is integrated on the movable carriage and moves together with the electrospindle. The tool change is very quick because it is not in a fixed position. The standard exchange arm system, typical of traditional machine tools, allows a drastic reduction of the time required for the tool change operation.

STROKES

At the end of the machine strong and rigid strokes are used as reference point of the bar. Each stroke is driven by a pneumatic cylinder and can disappear. It is automatically selected from the machine software, depending on the machining to be executed. The central strokes can be provided as optional.

CNC CONTROL

The industrial CNC is open and limitless. The control can be ECS (YASKAWA engines) or SIEMENS (SIEMENS engines). The control pulpit is assembled on a mobile support. The user interface is a 15 "color display with USB keys for remote interfacing with PC and CN, complete with push-button panel. Mouse, keyboard and remote handwheel are available on request.
