Precision Edge Grinding for Enhanced Electrode Connectivity
The MLCC Chamfering Machine is a critical asset in the post-sintering stage of multilayer ceramic capacitor production. By providing controlled edge rounding (chamfering), the machine ensures that the internal electrodes are perfectly exposed for subsequent termination processes. This precision grinding prevents the "shielding" effect of ceramic burrs, directly improving the electrical connectivity and reliability of SMD components used in high-frequency automotive and telecommunication circuits.
Advanced Centrifugal Planetary Mechanism
Engineered with a high-speed planetary transmission system, this machine utilizes centrifugal forces to tumble ceramic chips within four specialized rubber barrels. This motion ensures that every component—from tiny 0402 to larger 1812 chips—receives identical grinding intensity. The result is a perfectly smooth, defect-free surface finish that significantly reduces the risk of mechanical cracking during automated PCB assembly.
Intelligent Programming and Frequency Control
Modern electronic ceramic manufacturing requires flexibility for different material formulations. Our chamfering system features an intuitive touchscreen control that allows operators to store up to 8 distinct process curves. By adjusting the rotational speed from 0 to 960 rpm across 5 programmable time stages, manufacturers can optimize the grinding process for specific hardness levels, minimizing material loss while maximizing the quality of the edge profile.
Durable Construction and Occupational Safety
Longevity and safety are at the core of the design. The chamfering barrels are lined with 6–10 mm of high-abrasion rubber, which not only extends the machine's service life but also dampens noise and prevents impact damage to sensitive ceramic layers. For operator protection, the unit is enclosed with a robust safety cover and emergency stop features, making it ideal for both continuous mass production and specialized R&D laboratory environments.
Optimized Layout for Modern Production Lines
With a compact footprint of 1350 × 1150 × 1550 mm, the MLCC Chamfering Machine integrates seamlessly into existing factory layouts. Its high-capacity 30L tank allows for significant batch throughput, helping manufacturers meet the growing demand for 5G components and consumer electronics. The use of premium industrial components and a stable steel frame ensures vibration-free operation at peak speeds, delivering repeatable results batch after batch.

Frequently Asked Questions
Chamfering rounds off the sharp edges of sintered ceramic chips. This not only prevents micro-cracks during handling but also exposes the internal electrode layers, allowing for a better bond with the external termination paste.
Standard vibratory bowls can be slow and uneven. The planetary mechanism uses centrifugal force to create much higher energy impacts and a more consistent tumbling path, resulting in faster processing and more uniform edge quality.
Different materials require different grinding profiles. You can start with a high-speed stage for rapid deburring and finish with a lower speed for a smooth, polished surface, all programmed into a single process curve.
Yes. The abrasion-resistant rubber barrels are compatible with various ceramic and steel grinding media, as well as wet or dry grinding processes, depending on your chip specifications.
The machine is highly compatible with a wide range of SMD formats, starting from ultra-small 0402 sizes up to larger 1812 chip sizes (including 0603, 0805, and 1206 formats) with uniform precision.
The machine runs on an industrial-grade 3-phase AC 380V, 50Hz power standard. It features a compact production footprint with physical dimensions of 1350 × 1150 × 1550 mm.
