Troubleshooting Manual for Carbon Steel Sheet Chamfering and Deburring Machines - 90% of Failures Can Be Solved On-Site

Core Theme: Fault phenomenon → cause analysis → solution, a practical guide
In the process of deburring and chamfering carbon steel sheets after laser, stamping or waterjet cutting, equipment failures are mainly concentrated in three types: "uneven chamfering, burr residue and high equipment noise". The following provides a quick troubleshooting solution:
 

Fault Phenomenon	Core Causes	On-site Solutions
Uneven chamfer size	1. Fluctuating conveying speed;2. Uneven roller brush pressure	1. Stabilize the conveying speed (adjustable from 0.5-6m/min) with a variable frequency governor and real-timely monitor with a speed sensor;2. Calibrate the four-column lifting system to ensure pressure ≤0.01MPa and detect with a pressure tester
Edge burr residue	1. Overly fine abrasive grit size selected;2. Incorrect feeding direction	1. Replace with 80-120 mesh abrasives (suitable for the high hardness of carbon steel sheets);2. Adjust the sheet feeding direction to make the burr surface face the grinding head with reference to the schematic diagram in the equipment operation manual
Equipment noise ＞85dB	1. Bearing wear;2. Unbalanced roller brush	1. Perform dynamic balance correction on the roller brush or replace it directly, and complete the correction with a dynamic balancing instrument
Increased surface scratches	1. Iron filings remaining on the abrasive roller; 2. Unclean sheet	1. Clean iron filings on the abrasive roller with a high-pressure air gun or replace the abrasive;2. Add a sheet preprocessing process to remove oil stains and oxide scale
Excessively large chamfer fillet	1. Slow processing speed;2. Excessive pressure	1. Increase the conveying speed (2-4m/min is recommended for carbon steel sheets);2. Reduce the roller brush pressure, adjust the lifting height in a digital way and operate with reference to the equipment parameter table

Safety and Maintenance Supplements

1. Operators must wear protective goggles and high-efficiency dust masks to prevent inhalation of processing dust containing iron oxide and protect occupational health. It is recommended to replace the masks regularly to ensure the protective effect.
2. Check the feeding system daily: permanent magnet adsorption conveying must ensure sufficient magnetic force (suitable for carbon steel parts with size ≥10mm×10mm), and vacuum adsorption system must check the negative pressure value (≥-0.06MPa) with a magnetic force tester and a vacuum pressure gauge.
3. Clean the inside of the equipment weekly, focusing on the filtration system to prevent dust accumulation from causing motor overload. The filtration system can be disassembled for in-depth cleaning, and the filter element blockage can be checked.

Emergency Treatment: When the equipment is jammed, press the emergency stop button immediately. After the equipment stops completely, clean it with special tools. It is strictly forbidden to operate by hand directly while the equipment is running to avoid equipment damage and personal injury.
