Basic knowledge of marble parquet cut by water jet cutting machine

First, the marble parquet to draw a negative map, according to the different materials and treatment, parquet processing plans should be preserved. Save the need to pay attention to the order, select CAD2000 DXF file format, check the "select object" box. First select the form of the first choice in turn. Note that if the ring, such as the ring, you should first select the inner ring, and then choose the outer ring, water jet cutting machine diagram should not have other non-water knife pattern.Marble parquet drawing 1.

Second, the original size of the marble mosaic map is basically a single outward expansion of about 0.3mm to make up for the gap generated by water cutting. If the ring, the inner ring inward expansion of about 0.3mm, the outer ring outward expansion of about 0.3mm (due to the waterjet cutting machine nozzle uncertainty, the expansion of the distance will change).Third, tracing the starting point should be moved to 0:00 CAD dots, respectively, to the right and left offset 3mm. Marble mosaic of the line for the polyline, that is, including circular, circular and linear lines should be converted to polyline. For cnc waterjet cutter You can use the JOIN command to merge, merge the first choice into the knife line, and then select the middle of the polyline, and finally select the knife line. There are many ways to add in and out of the water knife line, you can extend the original line segment, can also be manually added at the endpoint. If you have a circular arc or straight line, you can first use the PEDIT command to convert it to polyline and then merge. 1: BO picking boundary 2: expanding edge 3: breaking up 4: PEDIT turning polyline 5: adding cutting line 6: J merging, from feeding line to cutting line.Water Jet Cutting machine

Waterjet Cutting parameters
Pressure: 380MPa
Water nozzle: 0.33mm (13 #)
Abrasive nozzle: 0.889mm
Sand material: 80 mesh
Motor: 37kw (50hp)
Water flow: 3.7L/min
Sand Flow: 0.54kg/min
Note:
1, the cutting speed mm / min.
2, the table shows the cutting speed, for a higher cut quality, you need to be reduced accordingly cutting speed.
3, the table working pressure of 380MPa, if the working pressure up to 410MPa, speed will be submitted to 15%; under maximum pressure conditions, the service life of the high-pressure parts will be significantly reduced.

Several forms of water jet cutting machine

  In the abrasive situation to points: water cutting with abrasive and without abrasive cutting.
       With equipment to points: divided into large and small water jet cutting water cutting.
       Pressure to points: divided into high-and low-pressure type, generally 100Mp as boundaries. 100Mp more high-pressure type, 100Mp following is a low pressure type. The 200MP above is UHP type.
       Technical principles to points: divided into pre-and post-Mix-Mix.
       Safety cut to points: cutting into the safety and non-safety cut class, the main difference in pressure above, 100Mp the following low pressure type water jet cutter can be applied.
       Special industries such as: hazardous, areas of oil, coal, hazardous materials handling. After a lot of experiments it was found that when the pressure exceeds a certain threshold, even if the water will put some sensitivity to chemicals detonated, and sediment containing abrasive waterjet cutting due to the sand, the sand and the potential impact and objects collide, producing the energy can also cause instability specialty chemicals, after a lot of experimentation and demonstration, and finally come to its threshold at around 237.6MP. Therefore, in the water cutting industry, people on the 200MP above waterjet cnc cutting is mainly used in the machining industry.
