In the field of optical device processing, purple filters are widely used in industries such as machine vision, sensor modules, medical testing, and scientific research instruments due to their precise filtering ability for specific wavelength bands of light. However, at the same time, purple filters usually have the characteristics of brittle materials, thin thickness, and extremely high requirements for edge quality, which poses higher challenges to the cutting process.
Customer requirements:
The customer needs to process the purple filter into a standard circular shape, with extremely high requirements for cutting accuracy and edge quality. The cutting edge should be smooth without any chipping or micro cracks, and the thermal effect should be strictly controlled to avoid burning, whitening, or performance changes. The circular size consistency and batch processing stability should be ensured to meet the requirements of subsequent precision assembly and mass production applications.
Solution:
Chuangkeda's "Infrared Picosecond Laser Glass Cutting Integrated Machine" achieves non-contact, low thermal impact, and edge free cutting with a high-energy density picosecond laser source, intelligent visual positioning system, and high-precision motion platform. During the cutting process, laser energy is evenly applied to the inside of the glass, forming a clean cross-section through the principle of cold cracking. The entire cutting edge can be directly assembled and used without the need for secondary polishing. For complex irregular paths, the intelligent control system of the equipment can operate accurately according to CAD drawings, ensuring that every arc and angle matches the design perfectly. The cutting accuracy of the equipment is as high as ± 0.01mm, with excellent verticality of the incision and a broken edge of ≤ 5 μ m; Supports cutting of any shape, whether circular, square, curved, or irregular contours, all can be completed in one go. At the same time, the automated processing platform equipped can achieve synchronous cutting of multiple pieces of glass, significantly improving production efficiency and providing high-quality and high-efficiency solutions for high-end glass precision processing.
Effect display:
• Processing material: 1mm "purple filter"
Cutting accuracy: ± 0.01 mm
• Edge collapse control: ≤ 5 μ m
• Processing effect: After cutting, the circular contour of the purple filter is complete, with consistent roundness, smooth and delicate edges, no broken edges or cracks, uniform and clean cross section, and no obvious thermal influence or discoloration phenomenon overall. The dimensional accuracy is stable.
• Processing advantages: Supports cutting of circular, square, and various shaped glass. R-angle, elliptical, and complex contours can be processed with high precision, ensuring stable mass production and strong dimensional consistency.
