Stone slabs are ushering in rapid development, product sales are increasing, the demand for processing and cutting and deep processing of various types of furniture are also increasing, and they are facing more and more processing problems. At the same time, processing technology is also changing. Get more and more perfect. The following is the cutting and processing experience summarized by the rock slab processing master. It is recommended to collect it!
Slab Cutting and Processing
1. Before processing, you should check the processing method given in the technical parameter table of the product to be installed, and process the product based on the selected installation method.
When designing kitchen countertops, leave at least 50 mm from the edge of any hole or groove in the countertop. Similarly, at least 50 mm must be reserved between two adjacent openings.
Design of interior corners and openings. As you normally would with stone, marble and joint materials, mark the corners with an arc length of at least 5 mm to spread the pressure.
Right-angled internal corners can be cut directly with a waterjet, but this is not recommended. Because of this inner corner design, the risk of cracking of the countertop will increase during processing, handling, transportation and installation, thereby endangering other items in the kitchen
When inspecting the sink or hob, leave a margin of at least 2 mm to avoid the effects of expansion.
When embedding the prefabricated sink, chamfer the edge of the hole in the 18mm rock plate.
When embedding a prefabricated sink or stove, use special glue or silicone resin or similar functional products to seal it.
Use one or two support posts to support the embedded sink to avoid excessive stress on the countertop.
When installing the cooking table, leave a distance of 2-3 mm from the wall.
When designing an "L" shaped countertop, it is best to use a straight style. When installing, use special glue to bond the joints. Angled joints are not recommended.
Check whether the directional texture of the joint is consistent to ensure the best joint effect.
Product processing can use saw blades or waterjet cutting machines specially designed for cutting rock slabs. A cutting machine for straight-line cutting of flat glass can also be used. (Quartz stone processing equipment can be used for rock slab processing, but the quartz stone saw blade needs to be replaced by a rock slab saw blade).
2. Before cutting, check the cutting machine, especially in the following aspects:
Cutting tools should be suitable for slate products and have good performance.
The workbench of the machine must be clean, durable, solid, and free of damage.
MachineThe machine's work surface must be perfectly level.
The workbench of the machine must be free of waste materials from previous processing, and everything on the surface must be normal. Therefore, it is recommended that before cutting, the processing operator takes samples for actual testing and makes actual adjustments to achieve the best results.
If you are not satisfied with the cutting effect, or the rock plate cracks during the cutting process, it may be due to the feed speed, operating pressure, improper prop speed during cutting, uneven cutting table, or the rock plate cracking during the cutting process. Movement or vibration, improper cutting tools and other reasons.
After processing, you need to pay attention when handling the rock slabs, especially if there are openings or holes in the middle of the slabs. Use multi-cup suction cups to avoid lifting both ends of the board directly over the edge to avoid bending of the finished product. Be careful when moving vertically manually to avoid twisting and breaking.
3. When cutting, use a special cutting blade suitable for rock slabs or a high-quality diamond cutting blade suitable for porcelain products, and perform it on a cutting machine.
Both U-shaped cutting blades and toothless saw blades can be used.
During the cutting process, the rock plate must be fed in the same direction as the cutting blade rotates.
The cutting opening is proportional to the thickness of the cutting blade.
Before cutting, check the cutting machine. The workbench must be in good condition, flat, completely level, and free of processing waste.
The smaller the radius of the cutting blade, the greater the spindle speed.
The slower the feed speed, the better the cutting effect.
Slow feed speed ensures less edge chamfering.
Feeding and discharging speeds should always be 50% slower than rated speed.
The right direction and the right amount of water.
As little as possible of the cutting blade should be exposed, at least one millimeter beyond the board thickness.
The lower the vibration during cutting operation, the better the effect. To reduce vibration, place disposable wooden boards or rubber-based (e.g., vulcanized rubber) boards under the rock slabs.
Set up the machine to cut rock slabs diagonally. In order to join two rock slabs and cut them at 45°, the cutting edges need to be chamfered.
When cutting at 45°, a thickened cutting blade can be used to reduce vibration during cutting and reduce the risk of rock slab breakage.
When performing "L"-shaped cutting, first find an angle to drill a small round hole, and then cut in a straight line. The part close to the round hole needs to be processed manually with an angle grinder.
After each processing is completed, but before the cut product is dry, use clean water to clean the dust left by the surface rock slab processing. After a series of cuts, use aluminum oxide or quartz blocks to maintain the cutting blades.
