I. Core Equipment for Custom Processing
Custom Cutting Equipment: In addition to conventional CNC shearing machines (suitable for custom blanking of sheets with thickness ≤ 50mm, accuracy ±0.1mm) and laser cutting machines (for cutting complex custom shapes such as special-shaped parts and hollowed patterns, no burrs), manual plate cutters can be used for small-batch customization (low cost, suitable for simple custom sizes, accuracy ±0.5mm). For custom cutting of extra-thick sheets (>50mm), heavy-duty CNC cutting machines are required (maximum cutting thickness up to 100mm).
Custom Molding Equipment: CNC milling machines/ machining centers are the core (meeting the processing needs of custom grooves, hole positions and special-shaped structures, equipped with replaceable cemented carbide tools, rotational speed 8000-12000rpm, suitable for different custom precision requirements). For mass customization of simple hole positions or shapes, punch presses with custom molds are used (molds are processed according to customer drawings, with a single stamping efficiency of 30-50 pieces per minute). For thick sheet customization, large surface grinders are needed (ensuring the flatness of custom parts ≤ 0.02mm/m to meet high-precision assembly requirements).
Custom Finishing Equipment: Chamfering machines (for the edges and corners of custom parts, adjustable chamfer angle 0-45°, avoiding scratches during assembly); polishing machines (when custom surface roughness is required, diamond grinding wheels are used for rough polishing (600 grit) and fine polishing (1200 grit) to achieve a mirror effect with Ra ≤ 0.8μm); if custom parts need to be spliced, hot melt adhesive machines are used (temperature 180-200℃, ensuring the splice is firm and suitable for different custom length requirements).
Custom Auxiliary Equipment: Dust removal equipment (a large amount of dust is generated during custom processing; industrial vacuum cleaners or bag filters are used to prevent dust from affecting custom precision); testing equipment (calipers, micrometers, projectors, which test dimensions item by item according to customer custom drawings, with precision error controlled within ±0.05mm); custom mold processing equipment (such as wire cutting machines, used to make custom molds for punch presses to meet the custom needs of special shapes).
II. Key Technologies for Custom Processing
Custom Cutting Technology: When laser cutting custom parts, adjust the power (300-500W) and speed (1-5mm/s) according to the sheet thickness. For complex special-shaped customization, segmental cutting is required to avoid carbonization. For custom blanking with shearing machines, adjust the blade gap to 5%-8% of the sheet thickness to prevent custom size deviation or sheet cracking.
Custom Cutting Technology: Adjust parameters according to custom precision requirements. For high-precision customization (such as precision parts), adopt the "high rotational speed, low feed rate" mode, with cutting speed 100-120m/min and feed rate 0.1mm/r; select PCD tools to reduce edge chipping. For ordinary custom parts, the rotational speed can be appropriately reduced to 8000rpm and the feed rate to 0.2mm/r. Coolant should be sprayed during cutting to ensure the surface of custom parts is smooth.
Custom Hole Processing Technology: For custom special holes (such as stepped holes and inclined holes), first pre-drill positioning holes (diameter is 1/3 of the finished hole), then process with custom tools. For custom deep holes (hole depth > 5 times the hole diameter), drill in segments, with each segment depth not exceeding 3 times the hole diameter; remove chips in a timely manner to avoid hole position deviation.
Custom Surface Treatment Technology: When customers require custom surface textures, sandblasting equipment is used (80-120 grit abrasive is selected to create matte or non-slip textures); for custom parts that need to be bonded, sand the surface with 800-grit sandpaper to improve adhesion and ensure the bonding strength reaches more than 5MPa.
III. Precautions for Custom Processing
Before customization, check customer drawings and clarify requirements for size, precision and surface; conduct sampling inspection of custom parts in each batch during processing to avoid batch errors; high-temperature processing (such as flame cutting) is strictly prohibited for bakelite sheet customization to prevent material embrittlement from affecting the performance of custom parts; custom molds need regular maintenance to ensure the consistency of subsequent mass customization.
