Mechanical characteristics and use

The Serrmac RAG 25/L stands out for its drilling precision and its ability to work on various materials such as steel, aluminum, plastic, and light alloys. Thanks to the mechanical speed change, the operator can adapt the spindle speed to the specific material being drilled, reducing the risk of errors or damage. The spindle, thanks to its CM2 Morse taper , allows for quick bit changes.

Using the Serrmac RAG 25/L is simple and intuitive: once the workpiece is secured to the base, the operator selects the desired speed and can begin drilling. Thanks to the adjustable column, it is possible to drill workpieces of various sizes and thicknesses, always ensuring maximum precision.

Compatible accessories

The Serrmac RAG 25/L column drill is compatible with various accessories that extend its versatility:

• Clamps for holding the workpiece : useful for holding the workpieces during drilling.
• Tips of various diameters : thanks to the Morse Taper attachment, it is possible to use tips of different types, depending on the required machining.
• Lubrication devices : Useful for drilling through tougher materials such as steel.

Mathematical formulas for optimal parameters

For optimal use, it's important to calculate the correct spindle speed based on the material being drilled. The most common formula is:

Rotation speed (rpm) = (Cutting speed x 1000) / (π x Tip diameter)

Where the cutting speed varies depending on the material: for example, for steel a speed of around 30-35 m/min is recommended, while for aluminium 60-80 m/min.

Maintenance

To ensure optimal operation of the Serrmac RAG 25/L , it is essential to perform regular maintenance. This includes:

• Lubrication of guides and spindle : to avoid friction and premature wear.
• Cleaning the base and spindle : removing machining chips to maintain accuracy.
• Checking the belts and gears of the gearbox : to ensure that the drill runs smoothly.

Safety regulations

As a used machine, the Serrmac RAG 25/L may not comply with the latest CE regulations. However, it is possible to upgrade the machine to current standards by installing guards for rotating parts and adding emergency stop devices. This makes the drill completely safe to use and compliant with current standards.

How to evaluate if it is a good used one

Checking the condition of the spindle and base is crucial to determining whether the Serrmac RAG 25/L is a good used machine. Checking the wear of the moving parts and the functionality of the gear change can provide important information on the machine's maintenance level. A drill that has only undergone minor repairs, as in this case, represents an excellent purchase opportunity.

Sectors of use

The Serrmac RAG 25/L is particularly suitable for:

• Mechanical workshops : for drilling operations on pieces of various sizes.
• Automotive sector : for the machining of precision mechanical components.
• Light carpentry work : ideal for drilling light alloys and metals.

Why buy it used?

Buying a used Serrmac RAG 25/L pillar drill offers a huge cost advantage without sacrificing quality. The savings compared to a new machine are significant, and considering the excellent condition of the machine, it's a safe and long-lasting investment. Furthermore, the reliability of the Serrmac guarantees high performance even after years of use.

In conclusion, the Serrmac RAG 25/L pillar drill represents an excellent deal for those looking for a used machine in excellent condition. With its robustness, precision, and versatility, it is an ideal choice for a variety of industrial sectors.
