三. Special Knowledge of Machine Components
Q6: What is the core structure and working principle of the A-03 trimming machine?
A6:The equipment adopts a dual-blade synergistic design:
-
Upper knife: High-speed rotating cutting, responsible for actively removing burrs;
-
Lower knife: Driven rotation, cooperating with the upper knife to form a shearing action, guiding and assisting the cutting.
During operation, the operator lightly places the workpiece against the knife position. The high-speed cutting of the upper knife combined with the driven rotation of the lower knife easily and thoroughly removes any type of burrs and flashes. Through precise control of cutting angle and pressure, it ensures that the upper, sole, or product body is not damaged during the efficient trimming process.
Q7: What are the key points to pay attention to in daily maintenance of the A-03 trimming machine?
A7:To ensure long-term stable operation and trimming accuracy, it is recommended to perform the following maintenance:
-
Lubrication: The machine is equipped with 4 oil holes. It is recommended to add 1 drop of engine oil to each oil hole every 2-3 hours. Important: DO NOT use sewing machine oil (needle oil), as it has a cleaning effect that will wash away the original lubricating film, causing component wear. Use ordinary automotive engine oil (such as that used for motorcycles or car engines) for lubrication and friction reduction.
-
Cleaning: Regularly remove debris and dust accumulated on the blade and machine body;
-
Blade inspection: Regularly check whether the upper and lower knives are sharp. Replace or sharpen them promptly if worn or chipped to ensure trimming quality;
-
Fastening check: Regularly check whether screws in all parts are loose to ensure operational safety.
Q8: What are the respective functions of the upper knife and lower knife on the A-03 trimming machine? Can they be replaced separately?
A8:The upper knife is the actively rotating cutting tool, generating cutting force at high speed to remove burrs. The lower knife is the passively driven tool, which is driven to rotate when the workpiece contacts it, providing support and auxiliary shearing for smoother and more thorough trimming. Both the upper and lower knives are independently replaceable components. When a blade is worn or damaged, the upper or lower knife can be replaced individually without scrapping the entire set, effectively reducing maintenance costs. It is recommended that customers keep a spare set of knives on hand to reduce machine downtime.
四. Standard Operation Process
Q9:What is the standard operation process of the ASFROM A-03 trimming machine?
A9:The machine is simple to operate. The standard process is as follows:
-
Pre-operation check: Confirm the power connection is normal; check that the upper and lower knives are firmly installed without defects;
-
Start the machine: Turn on the power switch; the motor drives the upper knife to reach normal operating speed;
-
Trimming operation: The operator holds the workpiece (sole, upper, leather goods, etc.) and lightly contacts the knife position at an appropriate angle, moving smoothly along the burr edge to complete the trimming;
-
Quality inspection: Check whether the trimmed product edge is smooth, free of residual burrs, and undamaged;
-
Cleaning and shutdown: After operation, clean the debris from the blade and machine body, and turn off the power.
Q10: How can the A-03 trimming machine ensure no damage to the product body during operation?
A10:The equipment ensures trimming precision and safety through the following features:
-
Synergistic effect of upper-knife high-speed cutting + lower-knife driven rotation concentrates cutting force at the burr position with minimal impact on the product body;
-
Operator technique control: It is recommended that operators hold the product at a 20-30 degree tilt angle against the knife and move smoothly along the burr edge, avoiding excessive force or prolonged停留 at the same position;
-
Blade sharpness: Keeping blades sharp effectively reduces cutting resistance and avoids拉扯 damage caused by dull knives;
-
Applicable material range: The machine is designed for soft to medium-hardness materials (rubber, EVA, PU, leather, etc.). It is not recommended for use on hard plastics or metal materials to avoid damaging the knives and the product.
五.Machine Structure & Components
Q11:What are the core components of the ASFROM A-03 trimming machine?
A11:The machine mainly consists of the following 5 core components:
-
Base and body: Supports the overall structure and provides an operating platform;
-
Upper knife system: High-speed rotating cutting tool that actively removes burrs;
-
Lower knife system: Passively driven tool that provides support and auxiliary shearing;
-
Motor drive system: 0.25KW single-phase motor that drives the upper knife to rotate;
-
Lubrication system: 4 oil holes for regular oiling of moving parts.
Q12: What are the specific positions of the lubrication system of the A-03 trimming machine and the oil requirements?
A12:The machine body has a total of 4 oil holes (please refer to the maintenance manual diagram for specific locations), corresponding to different moving joints and bearing positions. Oil requirements are as follows:
-
Prohibited: Sewing machine oil (needle oil), as its cleaning function will wash away the original lubricating film on component surfaces, accelerating wear;
-
Recommended: Ordinary automotive engine oil (such as that used for cars or motorcycles), providing lubrication, friction reduction, and rust prevention;
-
Frequency: It is recommended to add 1 drop of oil to each oil hole every 2-3 hours of continuous operation to maintain adequate lubrication of components.

七. Safety & Performance
Q15: What are the safety precautions when operating the A-03 trimming machine?
A15:To ensure operator safety, please pay attention to the following:
-
Hand safety: Keep hands at a safe distance from the knife during operation. Never touch the blade directly with hands while the knife is running;
-
Workpiece fixing: When trimming small workpieces, use auxiliary tools (such as clamps) to secure them, preventing the workpiece from being pulled into the blade;
-
Eye protection: Operators are recommended to wear safety goggles to prevent cutting debris from splashing into the eyes;
-
Maintenance shutdown: Turn off the power and wait for the blade to come to a complete stop before performing blade replacement, cleaning, or lubrication;
-
Power safety: Ensure the power cord is not damaged and the equipment is properly grounded to avoid electric shock risks.
Q16: What are the common blade issues after long-term operation of the A-03 trimming machine? How should they be handled?
A16:Common issues and solutions are as follows:
-
Blade dulling: Increased trimming resistance and uneven edges. Solution: Replace with a new blade or remove for sharpening (recommended to be performed by professionals);
-
Chipped blade edge: Jagged marks appear during trimming. Solution: Replace the blade immediately to avoid product damage;
-
Loose blade: Excessive vibration and abnormal noise during trimming. Solution: Stop the machine and check the tightening screws; confirm the blade is firmly installed;
-
Lower knife not rotating freely: Lower knife is stuck, causing unsmooth trimming. Solution: Check whether the oil holes are blocked and replenish lubricating oil; replace bearings if damaged.
It is recommended that customers inspect the blade condition quarterly and establish a blade replacement schedule based on actual usage frequency. Keep spare blades on hand to minimize production downtime.
八. Model Selection Consultation
Q17:What key conditions should be confirmed when purchasing the ASFROM A-03 trimming machine?
A17:Purchasing requires confirmation of 3 core dimensions:
-
Power supply conditions: Confirm the factory site voltage (e.g., 220V/110V) and frequency (50Hz/60Hz). The machine standard is 220V/50Hz single-phase. Consult the brand to confirm whether customization is supported;
-
Material type and hardness: Confirm the main material types to be trimmed (rubber/EVA/PU/leather/fabric) and their hardness range to evaluate blade suitability and cutting performance;
-
Daily output requirements: The A-03 is a single-station manual machine. Assess whether it matches daily output targets. For mass production, consider multiple units or consult the brand for automated trimming solutions.
Q18:Can knives for different purposes be replaced by the user after the A-03 trimming machine is delivered?
A17:Yes. The A-03 is designed with user-friendly maintenance in mind. Replacement of the upper and lower knives is considered a routine maintenance operation. The specific steps are as follows:
