Equipment Inspection: Ensuring the “Healthy” Operation of Equipment

Processing equipment serves as the “core weapon” in tungsten carbide die processing, and its performance directly impacts the safety and quality of processing. A comprehensive and in-depth inspection of the processing equipment is crucial, covering all aspects such as the precision of the machine tool, lubrication system, cooling system, and electrical system. Only by ensuring that the equipment is in good working condition can accidents caused by equipment failures be avoided. For example, insufficient machine tool precision may lead to significant dimensional deviations in the processed products, affecting die quality. Lubrication system failures can accelerate the wear of equipment components and even cause jamming, posing serious dangers.

Tool Preparation: Selecting the Right “Tools” for Safety

Preparing appropriate tools such as cutting tools, fixtures, and measuring tools according to the processing requirements is a vital step in ensuring processing safety. It is necessary to ensure that the tools are of reliable quality and undergo strict inspection and commissioning before use. The sharpness and integrity of the cutting tools directly affect the processing effect and safety. Dull cutting tools can increase the cutting force, causing excessive equipment vibration and even leading to tool breakage and injury accidents. The clamping effect of the fixtures is also of utmost importance. If the fixtures are loose, the workpiece may move during processing, resulting in collisions and other dangers.

Safety Protection: Building a Comprehensive Safety Net

The processing site should be equipped with complete safety protection facilities, such as protective covers, protective nets, and safety warning signs, to construct a solid physical defense line for processing personnel. At the same time, processing personnel must wear personal protective equipment that complies with regulations, such as safety helmets, protective goggles, and protective gloves, to reduce safety risks at the individual protection level. These protective equipment can effectively block flying debris, prevent head injuries, and protect the eyes and hands from harm, acting as the “guardian angels” for processing personnel.

During Processing: Standardizing Operations and Strictly Adhering to Safety Red Lines

Strictly Abiding by Operation Procedures: Following Rules and Avoiding Violations

Processing personnel must be thoroughly familiar with the operation procedures of the machine tool and strictly follow the prescribed procedures for processing. Arbitrarily changing the processing parameters or engaging in non-compliant operations is like driving recklessly on a highway, which is very likely to cause serious consequences. For example, randomly increasing the cutting speed may cause the cutting tool to overheat and wear out rapidly, and even trigger a fire. Starting or stopping the machine tool without following the proper procedures may damage the equipment or cause personal injuries. Therefore, strictly adhering to the operation procedures is the basic requirement for ensuring processing safety.

Correctly Installing the Workpiece: Precise Positioning and Stable Processing

Accurately placing the tungsten carbide die to be processed on the machine tool worktable and firmly fixing it using fixtures or vacuum chucks is an important step to ensure processing safety. An inaccurately positioned or unstable workpiece is highly likely to move due to vibration during processing, causing collisions between the cutting tool and the workpiece and triggering safety accidents. Therefore, processing personnel should take the workpiece installation process seriously to ensure precise positioning and reliable fixation of the workpiece.

Reasonably Selecting Cutting Tools: Choosing Tools Based on Materials for Safety

Selecting appropriate cutting tools according to the processing requirements and workpiece materials is crucial. The cutting tools should be sharp and free from damage, and they should be firmly installed. During the processing, regularly check the wear condition of the cutting tools and promptly replace those that are severely worn. Worn cutting tools not only affect the processing quality but may also cause unstable cutting forces, leading to increased equipment vibration and higher safety risks. Therefore, reasonable selection and use of cutting tools are key links in ensuring processing safety.

Adjusting Machine Tool Parameters: Scientifically Setting Parameters for Stable Processing

Reasonably adjusting parameters such as the cutting speed, feed rate, and cutting depth of the machine tool according to the processing requirements and workpiece materials is the key to ensuring a stable and efficient processing process. Improper parameter settings, such as an excessively high cutting speed or a large feed rate, may cause the machine tool to overload or operate beyond its capacity, triggering equipment failures or even safety accidents. Therefore, processing personnel should scientifically adjust the parameters based on the actual situation to ensure that the processing process is carried out under safe and stable conditions.

Paying Attention to Cutting Fluid Use: Rational Lubrication and Cooling for Tool Protection

Rational use of cutting fluid during the processing can effectively reduce the cutting temperature and cutting force, improving the processing quality and tool life. Cutting fluid has cooling, lubricating, and cleaning functions, which can reduce the friction between the cutting tool and the workpiece and prevent the cutting tool from overheating and wearing out. At the same time, keep the cutting fluid clean and sufficient, and regularly replace it to avoid affecting the processing effect and equipment life due to contaminated cutting fluid.

Monitoring the Processing Process: Staying Vigilant and Timely Eliminating Risks

During the processing, processing personnel should always stay alert and closely monitor the operating status of the machine tool and the processing effect. Once any abnormal situations are detected, such as abnormal machine tool vibration, unusual sounds, or significant dimensional deviations in the processed parts, immediately stop the machine for inspection and troubleshooting. At the same time, regularly maintain the machine tool to ensure its long-term stable operation. By promptly monitoring and handling abnormal situations, safety accidents can be effectively avoided.
