The drilling operation is one of the most important stages in the mechanical machining of metal parts. Whether we’re talking about fasteners, mounting plates, clamps or complex assemblies, properly done drilling ensures accurate mounting, proper operation and durability over time.

At HAWEMA, we offer professional drilling services for metal parts and assemblies, integrated into the CNC machining flow and adapted to the requirements of each project.

Drilling is the process of making holes in metal parts using drills, special cutters or other cutting tools. It is an essential stage in the preparation of parts for:

• mounting with screws or pins,
• trecerea cablurilor sau fluidelor,
• fixarea altor componente mecanice sau structurale.

Through correctly sized and positioned drilling services, parts fit perfectly into assemblies, mount quickly and ensure optimal equipment operation.

Choosing a specialized partner for drilling brings a number of important advantages:

• High dimensional accuracy – diameters and positions controlled in relation to the technical drawing.
• Repeatability – same results for small or medium runs of parts.
• Surface quality – clean holes without excessive burrs, ready for assembly or threading.
• Integration into the production flow – drilling combined with milling, reaming, tapping or other operations.
• Optimizing working time – efficient processing with cycle times calculated for industrial production.

By carefully controlling the drilling process, we reduce the risk of deformations, non-conformities or assembly problems.

Drilling services cover a wide range of applications for metal parts and mechanical assemblies.

Standard drilling for metal parts

We perform classic drilling for:

• through holes,
• holes for screws and pins,
• holes for fasteners and fasteners.

The dimensions and tolerances are respected according to the technical drawings, so that the parts fit together perfectly.

Precision drilling and controlled positioning

For applications that require tight tolerances, we drill with:

• positioning in CNC coordinates,
• depth control,
• the possibility of processing in small or medium series.

This type of drilling is ideal for base plates, flanges, brackets and automated cell components.

Preparatory drilling for threading and reaming

In many projects, drilling is only the first step. At HAWEMA we can continue with:

• internal threading of holes,
• reaming for higher precision,
• additional processing of the edges (beveling, burr).
• Thus, the parts are delivered ready for assembly or assembly.

Drilling services cover a variety of materials and geometries:

Carbon steel and alloy steel.

Stainless steel and resistant alloys.

Aluminum and light alloys.

We can make drilling for:

• metal plates, covers, casings,
• mechanical supports, brackets, flanges,
• components for automation and production lines,
• post-processed fasteners and welded structures.

Drilling operations carried out at HAWEMA are used in:

• Mechanical industry – machines, tools and industrial equipment.
• Automotive – components that require holes for mounting or passing cables/pipes.
• Automations and Robotic Cells – Baseplates, Brackets and Fixtures.
• Metal constructions and structures – fasteners and assembly for welded structures.

Regardless of the field, quality drilling contributes directly to the reliability and safety of final assemblies.

To ensure consistent results, our drilling process is well defined.

Drawing and requirements analysis

• We take technical drawings and customer specifications.
• We identify all drilling operations and associated tolerances.
• We determine the optimal sequence of operations (milling, drilling, threading, etc.).

2. Preparation of parts and fasteners

• Fixing parts in suitable devices.
• Choosing the right drills and tools for the material.
• Setting cutting parameters for efficient and safe drilling.

3. Execution of the drilling operation

• Rulare program CNC acolo unde este cazul.
• Intermediate dimensional control, if necessary.
• Continuing with threading or reaming operations when required.

4. Dimensional checking and control

• Measuring hole diameters and depths.
• Checking the positioning in relation to other elements of the part.
• Possible integration with 3D measurement for critical parts.

HAWEMA combines experience in mechanical machining with the seriousness of a reliable technical partner. For drilling operations, we offer you:

• CNC machining experience – we understand both the manufacturing and assembly side.
• Constant quality – every step is monitored, from clamping to dimensional control.
• Flexibility – we work both with unique pieces and small or medium series.
• Meeting deadlines – we know how important on-time delivery is in industrial projects.

By working with HAWEMA, drilling operations become a well-controlled part of the entire production flow.

A major advantage is that drilling is not an isolated service, but integrated into our package of mechanical machining and technical solutions:

• CNC milling – machining contours and surfaces.
• Tapping and reaming – completing holes for mounting or sealing.
• Surface treatments through partners – browning, galvanizing, painting, etc.
• 3D measurement – ​​checking critical parts before delivery.

Thus, you can outsource the entire flow – from the semi-finished product to the machined part, drilled and checked.

In our practice, drilling operations are used in:

• base plates for robotic cells, with holes for clamping and adjustment,
• flanges for mechanical or hydraulic connections,
• consoles and supports for sensors, actuators and equipment,
• metal structures subsequently processed by other mechanical operations.

These examples show how important accurate drilling is for quick assembly and avoiding field repairs or adjustments.

If you need professional drilling services for metal parts or assemblies, HAWEMA is the right partner. We combine technical experience, modern equipment and attention to detail to deliver ready-to-assemble parts with precise holes and conforming to technical drawings.
