CNC machining specialists at your service

CNC machining (Computer Numeric Control) is a technique that involves using automated machinery for the production of mechanical parts for professional use.

Many industries rely on this process to obtain components tailored to their specific needs. This includes automotive mechanics, aerospace, and the healthcare sector, where components such as tablet presses are manufactured. In this process, technicians use a computer to input the necessary information for precise material processing.

As you may have understood, the equipment used for CNC machining at G.M Precision consists of mechanical tools and a numerical control system. The mechanical component includes the tools responsible for shaping the parts. When the system transmits information related to machining a part, the machine’s appropriate tools come into contact with the metal or material to give it the desired form.

The numerical control system refers to a control panel or interface through which the technician inputs information for part processing. It can be a computer with software tailored to the machine’s operation or a control panel integrated directly into the machine tool.

Machining centers represent the perfect union of mechanics and electronics. While one enables the production of mechanical parts, the other allows for precise design.

Using CNC machining services comes with a certain cost, which corresponds to the quality of the aluminum or iron mechanical parts obtained and always concludes with a quality control of the produced parts.

The materials used in CNC machining by a machining workshop are diverse. These include aluminum, steel, stainless steel, and more. Professionals in the aerospace industry, automotive mechanics, and sanitary equipment manufacturers use metal machining to:

Manufacture periodically produced parts

In the machining industry, there are products with seasonal demand in the market. To manufacture such parts, machinists can opt for standard equipment processing. However, choosing this type of design results in low processing efficiency and unstable quality. Additionally, it is difficult to guarantee the quantity.

Thanks to CNC machining centers, it is possible to produce periodically demanded parts in quantity, with precision, and save a considerable amount of time.

In fact, when a part is produced for the first time, the CNC machining center retains the manufacturing program along with all associated information. This allows for their reuse when needed.

Produce high-precision parts in quantity

Certain parts require high precision when manufactured. This facilitates their assembly during use. Thanks to the precision machining techniques used by a CNC machining center, professionals from various fields can obtain parts with finishes tailored to the design of their own products, and this can be done in large quantities.

Design parts in batches

CNC machining allows for designing demanding parts with precision and in large quantities. This technique is also suitable for batch production. To achieve a significant economic effect, it is sufficient to make the batch larger than the economic batch.

Produce parts with complex shapes

In machining, there are machines with four or even five axes. Likewise, many machines are equipped with advanced CAD/CAM technology. Furthermore, the use of DNC allows machinists to better meet processing needs. All of this optimizes the automated processing of complex parts.

Machined parts are produced using a variety of methods, including milling. These are combined with CNC machining for automated part design. The operating principle of this type of machining is the same everywhere. It comprises the following steps

Design of a CAD model
Conversion of CAD files into CNC programs
Preparation of the CNC machine
Execution of processing operations

• The advantages offered by CNC machining are as follows:

1.Process Concentration

In general, CNC machining machines are equipped with tool holders or tools that can be changed according to the work to be done or the different materials to be used. In a CNC machining center, tool changes are automatically performed from the program control panel. This ensures a relatively better concentration of operations.

The concentration of processes provides several benefits, including:

• Reduction in the machine or tool’s floor space
• Limiting or eliminating intermediate connections
• Machinists do not need to manually control the tools during CNC machining as the degree of automation is high.

2.Reduced Operator Requirements

In terms of training, it should be noted that professionals handling conventional machining tools require long hours of learning to gain experience in using the machines. This is not the case for CNC specialists. Indeed, the latter require only a short training period (one week) to start performing simple operations.

Furthermore, parts used in CNC machining machines offer higher precision, which is not the case with ordinary machining machines. Such a situation shortens the working time and, consequently, results in a significant increase in efficiency.

3.High Flexibility

CNC machining allows for the processing of parts with the most complex shapes. It should also be known that some parts cannot be machined on standard machine tools. This type of machining has the main advantage of offering professionals from various trades a wide variety of high-quality products.

CNC machining is suitable for the following occasions:

• Parts that are not allowed to be discarded
• Development of new products
• Processing of urgent parts”

Surface finishing in CNC machining encompasses several treatments carried out after the part has already been produced. These include

• Oxidation treatment: hardens the surface of the CNC product, making it difficult to wear.
• Paint treatment: to prevent the product from rusting
• Electroplating: the most common surface finishing technique used in CNC machining. In particular, it prevents the machined part from mildew or embroidery after long-term use.
• Polishing: makes the surface of the part pleasant to the human touch
• Silk-screen printing: consists in printing designs, shapes or words on aluminum or steel products resulting from a machining process.
• UV finishing: for brightening up machined parts
