Main components and dimensions:

• Axes of movementThe Fidia Digit 318 FH has 5 axes with movements in three main directions:
  • X-axis : 3000 mm
  • Y-axis : 1000 mm
  • Z-axis : 800 mm
• Electrospindle : 22 kW power, capable of reaching a maximum speed of 30,000 rpm, ideal for precision and high-speed machining.
• Tool holder : HSK50-E, a choice that guarantees excellent rigidity and precision in gripping tools.
• High pressure system : Used for cooling during machining, with a liquid and chip filtration system to keep the work area clean.

Mechanical characteristics:

The Fidia Digit 318 FH is designed for precise and fast machining, capable of working on a wide range of materials, from metals to composites. The machine is equipped with a Hi-Mill CAD/CAM , which simplifies the programming of complex machining operations, while the Fidia NC offers complete axis management for simultaneous operations in 5 directions.

How to use:

Using the Fidia Digit 318 FH is relatively simple thanks to the intuitive interface of the Fidia numerical control. Operators set the machining program using CAD/CAM software and load the workpiece into the work area. The high-precision positioning of the axes and the speed of the electrospindle ensure optimal results, reducing cycle times.

Matching accessories:

In addition to the integrated cooling and filtration system, the machine can be combined with various precision tools compatible with the HSK50-E tool holder. Automation devices for loading and unloading workpieces can also be connected, further optimizing productivity.

Mathematical formulas for optimal parameters:

To calculate the optimal cutting speeds, it is important to use the formula:

$$V$$

Where:

• V_c = cutting speed (m/min)
• D = tool diameter (mm)
• N = spindle rotation speed (rpm)

Maintenance:

Proper maintenance of the Fidia Digit 318 FH includes regular cleaning of the cooling system filters, lubricating the axes, and periodic spindle checks to ensure maximum speed is achieved without vibration. Checking the actuators and axis encoders ensures long-term precision.

Valuing a good used car:

When evaluating a Fidia Digit 318 FH , it's essential to check the spindle hours, the wear of the axis guides, and the quality of the cooling system. If these components are in good condition, you can be sure you're purchasing a machine that, even if used, offers high performance at a significantly lower cost than a new one.

Sectors of use:

The Fidia Digit 318 FH is primarily used in the precision mechanics, aerospace, automotive, and mold-making sectors. Thanks to its versatility and precision, it can work on materials such as aluminum, steel, and light alloys.

Purchasing this used machine offers significant advantages, especially in terms of cost savings and reliability, thanks to the robustness of Fidia .
