A Gillardon drill press is a versatile machine used to precisely drill into different materials. Below, a complete overview of its operation, use, existing types, workable materials, alternative machinery, calculations to optimize its operation and the reasons why it is better to buy a used model.

How it works and how to use a pillar drill

The drill press works via a chuck that rotates at different speeds, allowing a drill bit to penetrate the material being worked on. The column supports the spindle and feed unit, offering stability and precision.

Phases of use:

1. Mounting the bit: Select and mount the appropriate drill bit on the chuck.
2. Setting up the workpiece: The workpiece to be drilled is fixed on the work table, which can be adjusted in height and angle.
3. Speed ​​adjustment: The spindle speed is set according to the material and drill diameter.
4. Drilling: Lower the chuck using the lever, allowing the tip to penetrate the material to the desired depth.
5. Removing the Workpiece: Once the hole is completed, the chuck is raised and the workpiece removed.

Types of Existing Column Drills

Column drills can be classified based on specific characteristics:

1. Bench column drill: Compact model, ideal for precision work on small pieces and in limited spaces.
2. Floor column drill: Larger and more powerful model, used for work on larger pieces and for deep holes.
3. Radial drill press: Allows you to move the spindle on a radial arm, allowing drilling on large workpieces without having to move them.

Workable Materials

The Gillardon drill press can process a wide range of materials, including:

• Ferrous metals (steel, cast iron)
• Non-ferrous metals (aluminium, brass, copper)
• Wood
• Plastic
• Composites

The choice of drill bit and machine settings varies depending on the material.

Reciprocating Machinery

While versatile, the drill press is not always the only option for drilling. Some alternative machinery includes:

• Electric hand drill: Portable, used for less precise work or in confined spaces.
• Milling machine: Can perform drilling operations with greater versatility and precision.
• Magnetic drill: Used for drilling in particular positions, such as on vertical or elevated surfaces.
• Punching machine: For quick drilling on thin sheet metal without generating chips.

Calculations to Optimize Operation

Optimizing the operation of a drill press requires specific considerations:

• Rotational speed (RPM): Determined based on the material and diameter of the tip. An approximate formula is RPM=V⋅1000π⋅DRPM = \frac{V \cdot 1000}{π \cdot D} $RPM$ $=$ π ⋅ D V ⋅ 1000 ​, V is the recommended cutting speed for the material (in meters per minute) and D is the diameter of the tip.
• Feed (mm/rev): Speed ​​at which the tip advances through the material. Too fast a feed can cause the tip to break, while too slow a feed can excessively wear the cutting edge.
• Drilling depth: Adjustable via the depth limiter, important for precise and consistent drilling.
• Lubrication: Essential for reducing friction and heat, especially when drilling metal.

Why it is worth buying a used Gillardon drill press

Buying a used Gillardon drill press offers several advantages:

1. Economic savings: A used column drill costs less than a new one, allowing considerable savings.
2. Quality and robustness: Gillardon drill presses are known for their robust and long-lasting construction, meaning that a used model can still perform perfectly for many years.
3. Proven reliability: A used drill has already proven its reliability over time, reducing the risk of unexpected defects.
4. Immediate availability: Unlike a new drill that may require lead time, a used model is often available immediately.
5. Maintenance and spares: As an established brand, spares and technical support for Gillardon models are generally easily available, even for older machines.

In conclusion, a used Gillardon drill press represents a solid and advantageous investment for those looking for a reliable and precise drilling machine. With proper maintenance, a used drill can continue to offer high performance at an affordable cost.
