Quotation from a blueprint or machining rework

In the dynamism of the world of industrial manufacturing, two essential services stand out to guarantee the quality, precision and efficiency of production processes: the "Estimate on plan" and the "Resumption of Machining". These two fundamental elements play a crucial role in achieving finished products of the highest standards. Whether you are engaged in the design of complex parts or in mass production, understanding what these services consist of is essential to optimize your production chain and maintain a constant level of excellence.In this article, we will explore in detail these two key services and their impact on the industrial manufacturing sector.

Machining and these different stages

Machining is a technique used in the manufacture of mechanical transmission parts for many years. Various machining techniques are used to create different transmission parts such as shafts, gears, bearings and bearings.

Machining remains a precision technique used to create parts with very tight tolerances. This accuracy is important in mechanical power transmission applications because it helps to ensure the safe and efficient operation of transmission systems.

The different machining steps 

• Milling is a widely used machining process for removing material from a workpiece using a milling cutter. A milling machine is a rotating tool with sharp teeth placed on its edge. As the cutter rotates, its teeth slice, cut, or scrape the workpiece material.

• Shooting is a machining process in which a rotating part is formed by a tool attached to a carriage which moves along the axis of rotation of the part. The piece is mounted on a lathe, a workbench that precisely turns the piece. The knife is moved towards the part, removing material and creating various shapes such as cylindrical, conical, spiral surfaces, etc.

• Drilling involves creating holes in a workpiece with a drill. A drill is a tool that penetrates and removes material to form a hole. Drilling is essential for many applications, from creating simple mounting holes to making more complex holes for various purposes.

• bore is a machining process used to enlarge an existing hole or improve accuracy. A planer, a rotary tool with a sharp blade, is used for this purpose. The reamer is passed through the hole, removing excess material to achieve the exact dimensions desired. Boring is often used to improve the quality of finish, precise dimensions and tolerances of holes.

• Tapping involves creating threads in a hole to attach a screw or bolt. A tap is a turning tool with spiral threads. When converted to a pre-drilled hole, it cuts threaded grooves, creating threads that allow screws to fit. Threading is necessary in the manufacture of parts where screw connections are required.

• Grinding is a grinding process in which a grinding wheel, a rotating disc with an abrasive surface, is used to remove material from the workpiece. The grinder spins at high speed and can be used to shape metal parts, polish surfaces, sharpen tools and more. Grinding wheels are available in different grinding compounds for different machining needs.

The importance of machining

Precision machining plays an important role in the field of mechanical transmission, ensuring its smooth operation. The most important components of power transmission require very precise manufacturing. This is where computer numerical control (CNC) machine tools come in, capable of cutting parts with an accuracy of a few microns, which is essential to ensure perfect alignment and smooth interaction of elements. Although precision machining is an investment, its advantages are undeniable: the mechanical transmissions produced in this way are more durable and efficient than the lighter ones. This meticulous process ultimately results in a high-performance and reliable mechanical transmission.

Re-machining in mechanical transmission

Re-machining is a manufacturing technique used to extend the life of mechanical transmission components. Re-machining allows a damaged or defective part to be reconstructed to restore its original properties.

Re-machining is an economical technique that saves money on boxed spare parts. Recycling is also an environmentally friendly technique because it reduces waste.

The challenges of remanufacturing

Tolerance management : Transmission parts must be manufactured with extreme precision, which can be difficult to achieve. Tolerances must be precisely managed to ensure parts fit together properly and the transmission operates smoothly.

The quality of materials : transmission parts must be made from high quality materials capable of withstanding mechanical and thermal stresses. The materials used must also be compatible with each other to avoid corrosion and wear problems.

Equipment : Reproduction requires the use of specialized and expensive equipment. CNC machines are used for precision machining, and there are also expensive post-processing machines.

Labor : Recovery requires special skills and experience. Users must be competent in the handling of machine tools and repairs.

The different advantages of remanufacturing

• Time saving
• Money saving
• Extending the life of the part
• Improved part performance
• Increased security

When should you opt for remanufacturing rather than replacement?

The choice between re-machining and re-machining depends on several factors, such as component type, associated costs, expected performance, environmental impact, and other situational considerations. Here are some scenarios:

Serious damage : When a component is severely damaged or worn, replacement may be the only way to restore performance and safety.

Technological advances : When new technology or innovation becomes available, a replacement may improve performance, durability, or performance over a refurbished component.

Security : For safety-critical components, it is often best to replace them to ensure reliability.

Lifetime  : If a refurbished component is likely to fail again quickly, replacement may be more economical in the long run.

Compatibility : Sometimes it can be difficult to ensure that the upgraded component works seamlessly with other parts of the system, while the replacement component is designed for seamless integration.
