With the wide application of CNC plasma cutting machines in recent years, related product brands and manufacturers are gradually increasing. How to differentiate quality among many models and brands is becoming one of the problems faced by users. On the other hand, at present, there are no recommended relevant standards for the evaluation indicators of metal cutting quality in the country. There are only industry standards: “Heat cutting plasma arc cutting, quality and dimensional deviation†(JB/T 10045.4-1999). The evaluation of plasma arc cutting quality mainly includes the following aspects:
First, the width of the incision:
It is one of the most important characteristic values ​​for evaluating the cutting quality of the cutting machine, and also reflects the radius of the smallest circle that the cutting machine can cut. It is based on the size of the incision at the widest point, most plasma cutting machine incision width between 0.15 ~ 6mm. Impact:
1, too wide incision will not only waste material, but also reduce the cutting speed and increase energy consumption.
2. The width of the kerf is mainly related to the nozzle aperture. In general, the kerf width is always 10%~40% larger than the nozzle aperture.
3. When the cutting thickness increases, it is often necessary to use a larger nozzle aperture, and the incision will also be widened.
4, increase the width of the incision, will increase the amount of deformation of the cutting piece.
Second, the surface roughness:
It is used to describe the appearance of the cut surface and determine if rework is required after cutting. It is a measure of the Ra value on the cross-section of the incision depth at 2/3. As the result of the action of the cutting air flow in the longitudinal direction of the cutting advance, the main form is the cutting corrugation. The surface roughness after cutting by the oxyacetylene method is generally required: Grade 1 Ra ≤ 30 μm, Grade 2 Ra ≤ 50 μm, Grade 1 Ra ≤ 100 μm. The value of the incision Ra for plasma arc cutting usually exceeds the flame cutting level but is lower than the laser cutting Ra value (less than 50 μm)
Third, the squareness of the cut edge:
It is also an important parameter that reflects the quality of the cut and relates to the degree of rework that is required after cutting. This indicator is usually expressed in verticality U or angle tolerance. In general, the U value of the plasma arc cutting is closely related to the plate thickness and the process parameters, usually U ≤ (1% to 4%) δ (δ is the plate thickness), and the laser cutting U ≤ 0.5 mm.
Fourth, the width of the heat affected zone:
This index is very important for those hardenable or heat-treatable low-alloy steels or alloy steels. Excessively wide heat-affected zone widths can significantly change the performance near the incision. The width of the heat-affected zone of the air plasma arc cutting is about 0.3mm. When the underwater plasma arc cuts, the width of the heat-affected zone can also be narrower.
V. Slagging amount:
It is to describe how much oxide slag or resolidified material adheres to the lower edge of the cut after hot cutting. The level of dross is usually determined by visual inspection and is generally described in terms of none, minor, medium, and severe.
PCD Router Cutting Tools
PCD Routing Cutting has given added advantage to the furniture manufacturing industry and this has resulted in
increased use of overhead routers and shank tools, both straight and profile.
The common characteristics of this kind of machine are:
Use of small tool diameters (with reduced number of tips)
High RPM due to the production needs and quality of finish
Therefore tools need to be precision manufactured and balanced perfectly with a lasting cut.
OPT has an assorted range of tools for each of these operations depending on the users requirements.
