Machining

Range of machining services for industry

Machining is a technological process involving the controlled removal of excess material using cutting tools. In practice, it allows obtaining a specific shape, dimension, tolerance, and surface quality of the finished part. This is especially important where the component must fit into an existing system, work under load, or maintain repeatability in subsequent production batches.

The scope of services offered by Inbras includes primarily:

• CNC turning of rotating elements,

• conventional turning of single, repair, and larger parts,

• CNC milling of parts with more complex geometry,

• CNC plotter milling for large-format materials,

• sawing, threading, and rolling,

• CAD/CAM design and programming,

• manufacturing elements from metals and engineering plastics.

Such a wide range of work allows selecting the method according to the real application of the part, rather than the other way around. Planning the execution of a prototype differs from short series, and repeatable elements that must maintain identical parameters with each order are planned differently.

When is it worth choosing conventional turning?

Not every order requires CNC machine programming. In many cases, conventional turning is a faster, more flexible, and economically justified solution. This is especially true for single-piece production, service work, part replication, and components with larger diameters.

Conventional turning should be considered when:

• a single part is needed,

• the part is to be made based on a pattern,

• a quick response is necessary for machine repair,

• the part has a larger diameter than the standard CNC center range,

• the geometry of the element does not require an advanced CAM program.

At Inbras, conventional turning allows for machining elements with a maximum diameter of 550 mm and a length of up to 300 mm. This is important for repair parts, technical components, and parts that would be difficult to produce on a smaller turning center.

In this method, the operator's experience is of great importance. They continuously monitor the process, respond to material behavior, and can make adjustments without the need to re-prepare the program. Therefore, conventional turning remains an important element of the production infrastructure in the industry.

CNC Plotter Milling for Larger Material Formats

Some details primarily require a large working area. That's when CNC plotter milling is used. This technology works well for processing sheets, boards, and materials that have a larger surface area but do not always require deep, multi-axis spatial processing.

At Inbras, the CNC plotter has a working area of 3100 × 2100 mm. This allows for processing larger material formats and efficiently planning the cutting of many elements from a single board.

CNC plotter milling can be a good choice for:

• large-format plastic sheets,

• technical shields,

• gaskets,

• guiding elements,

• flat details,

• components from sheet materials,

• processing contours, grooves, and holes.

A big advantage of this method is the ability to optimize cutting layout. Correct placement of details on the sheet allows for material waste reduction, which is significant both cost-wise and organizationally.

CAD/CAM design as support for the production of details

Professional machining increasingly begins even before the machine is started. Key importance lies in the preparation of documentation, model, and processing program. CAD/CAM systems are used for this purpose, which support the design of the detail and the planning of tool work.

CAD allows developing a model or technical documentation. CAM enables the preparation of tool paths, which are then used by CNC machines. Thanks to this, the process flow can be better predicted, errors reduced, and execution time optimized.

CAD/CAM design and programming is particularly helpful when:

• the client only has a pattern of the detail,

• the documentation requires refinement,

• the part has a complicated geometry,

• the appropriate sequence of operations needs to be selected,

• machining time needs to be minimized,

• the detail is to be repeatable in subsequent series.

In practice, CAD/CAM support shortens the path from the idea or technical need to the finished element. This is important in industries where precision, predictability, and a quick response to maintenance needs are important.

If you do not have full documentation, but you have a sample of the element or a description of the need, contact us. We will check how we can prepare the detail for production.

Machining of plastics for various industries

Machining is not limited to metals. In many industrial applications, engineering plastics play a very important role. They are lightweight, chemically resistant, often have good sliding properties, and can replace metal where weight reduction, insulation, or resistance to a specific working environment are important.

Plastics used in machining may require a different approach than steel or aluminum. During machining, their temperature sensitivity, potential for deformation, and edge retention after machining must be taken into account. Parameter selection is of great importance here, because too aggressive machining can lead to overheating, melting, or deformation of the material.

Engineering plastic components are used, among others, in the following industries:

• machine,

• energy,

• aviation,

• automotive,

• chemical,

• food,

• production and maintenance.

Depending on the application, these can be guides, bearings, rollers, sliding elements, scrapers, seals, covers, and parts working in contact with other machine components.
