Manufacturing
Valve Plants
The industrial valve manufacturing process is a complex endeavor. It is not just a simple creation of the valve. We at Herminio perform rigorous tests of the valves to ensure proper functioning before sending it out of our production plants.
Double disc grinding
Double disc grinding uses two opposing abrasive wheels to simultaneously grind two sides of a blank.
- Grinding two sides of a part at the same time provides greater control of dimensional tolerances, flatness, and parallelism allowing double disc grinding to achieve required tolerances.
- Flatness- 50 to 100 microns
- Parallelism- 25 to 50 microns
- We have a capacity of manufacturing 0.5 million parts per month.
Lap Grinding
Lap grinding is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds.
- It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.
- A surface that has been lapped exhibits a dull, non-reflective and multi-directional appearance. This condition is referred to as “matte” finish.
- Parallelism- min 10 microns
- Flatness- min 50 microns
Brushing
Burrs are created from shearing, bending, cutting, piercing, and compressing materials.
- During deburring, the burr is removed, the edges are rounded and the surface is smoothed without significantly affecting the thickness of the workpiece.
- Brush deburring involves sliding a brush, which is coated with an abrasive or consists of bristles with integrated abrasive granules, over the punched part.
- Defined and reliable burr removal is essential for this process, as the setting parameters can be adjusted to the component geometry and material.
- A secondary burr is not formed after the process.
- This process is used for deburring fine blanked and sintered parts.
Ultrasonic Cleaning
Ultrasonic cleaning is a technology unique in its ability to remove contaminants that other technologies cannot remove and in its ability to effectively clean areas that are not accessible using other technologies.
- Items are submerged in a tank with liquid, which is then hit with high-frequency sound waves.
- Ultrasonic cleaning can be used for a wide range of workpiece shapes, sizes and materials, and may not require the part to be disassembled prior to cleaning.
