Considering the characteristics of stone
- Hardness: for high hardness stone, like granite, it is preferable to choose PDC composite piece with large diamond particles, high concentration and high hardness of bonding agent, which can ensure the cutting power and wear resistance; for lower hardness stone, such as limestone and sandstone, it is preferable to choose composite piece with smaller diamond particles and lower concentration, which can make the cutting edge sharper and the processing efficiency higher.
- Texture: stone texture is uniform, you can choose the conventional structure of the PDC composite sheet; uneven texture, fissures, impurities in the stone, you should choose a composite sheet with good impact resistance, such as diamond layer thicker, the bond toughness of the product, in order to minimize the composite sheet damage due to defects in the stone.
Clear processing requirements
- Processing technology
o Cutting: cutting process requires composite sheet with good sharpness and cutting speed, can choose sharp edge, diamond layer of thin PDC composite sheet, can reduce cutting resistance, improve cutting efficiency. o Engraving: engraving needs composite sheet with good impact resistance.
o Engraving: engraving needs composite sheet with high precision and good wear resistance to ensure the fineness and clarity of the engraving pattern, should choose diamond particles uniform, smaller size, good wear resistance composite sheet. o Grinding: grinding process needs composite sheet with good sharpness and cutting speed.
o Grinding: Grinding process needs composite piece with high wear resistance and stability, can choose composite piece with high diamond concentration and high bond strength, which can maintain the grinding effect for a long time and improve the efficiency and quality of grinding.
- Processing precision: processing of stone products requiring high precision, such as decorative lines, artistic sculpture, etc., you need to choose the PDC composite sheet with high dimensional accuracy and good edge flatness to ensure that the processed stone is accurate in size and smooth on the surface.
Applicable equipment type
- Equipment power: equipment power, you can choose a larger size, thicker PDC composite sheet, can give full play to the cutting ability of the equipment; equipment power is small, you should choose a smaller size, lighter weight composite sheet, to avoid excessive load on the equipment.
- Speed: high speed equipment, need to choose dynamic balance performance, high stability of the composite sheet, to prevent high speed rotation vibration and centrifugal force resulting in damage to the composite sheet or decline in processing accuracy.
- Installation: Different equipment composite sheet installation methods are different, such as bolt fixation, card slot installation, etc., according to the installation requirements of the equipment to choose the corresponding interface form and size of the composite sheet, to ensure that the installation is firm and reliable.
Focus on the quality of composite sheet
- Brand and reputation: choose a well-known brand, market reputation of PDC composite sheet, these products usually in the production process, quality control and other aspects of strict standards, product quality and performance is more guaranteed.
- Inspection report: Check the quality inspection report of the composite sheet to understand whether its hardness, wear resistance, impact resistance and other performance indicators meet the requirements to ensure reliable product quality.
Consideration of cost factors
- Purchasing cost: Under the premise of meeting the processing requirements, compare the prices of PDC composite sheets of different brands and specifications, and choose cost-effective products to reduce purchasing costs.
- Service life: Although the unit price of the composite sheet with long service life may be higher, comprehensive consideration of its processing efficiency and replacement frequency can reduce the overall processing cost and improve production efficiency
