Feedback on JQMT Shearing Machine

I. Introduction

II. Feedback on Operational Convenience

(I) Positive Feedback

1. Intuitive Dimension Setting: Many users appreciate the design of the dimension - setting area on the operation panel of the shearing machine. The numeric key input is clear and straightforward, and the way of switching the input mode through arrow keys or confirmation buttons on some models is easy to understand. This enables operators to set the shearing dimensions quickly and accurately, greatly improving work efficiency. For example, in a small - scale sheet - metal processing factory, newly - recruited employees can skillfully set the shearing dimensions of different sheets after simple training.
2. Convenient Speed Adjustment: Most users are satisfied with the adjustable shearing speed of the shearing machine. The obvious speed - adjustment buttons on the operation panel, whether they are "+" and "-" buttons or the precise numeric input method on high - end models, make speed adjustment easy. According to different materials and processing requirements, operators can quickly adjust to the appropriate shearing speed, reflecting the good adaptability of the equipment.

(II) Negative Feedback

1. Complex Operation Process: Although the dimension and speed settings are relatively convenient, the overall operation process is slightly complex for some beginners. Starting the equipment, running it, and switching between different functions require a certain learning cost. For example, in a newly - established processing enterprise, employees need to spend a relatively long time getting familiar with the complete operation process, which affects the initial production efficiency to some extent.
2. Insufficient Operation Tips: During the operation, the equipment does not provide clear enough tips for some key operation steps. For example, when switching to shear different types of materials, there is no clear indication to tell the operator whether other parameters need to be adjusted accordingly. As a result, some operators may affect the shearing quality due to improper operation.

III. Feedback on Maintenance

(I) Positive Feedback

1. Reasonable Lubrication Cycle: The recommended lubrication cycle of every 80 - 100 hours of operation has been recognized by users. Such a cycle can ensure the good operation of all components of the equipment without affecting the production progress too frequently. Moreover, the clear lubrication parts and detailed lubrication method instructions enable maintenance personnel to easily operate according to the equipment manual.
2. Clear Blade - Cleaning Instructions: The instructions on blade cleaning are very detailed. From cutting off the power supply to ensure safety, to the operations of using soft cloths, brushes, and special cleaning agents, and finally to the step of applying anti - rust oil, all provide clear guidance for users. This helps to extend the service life of the blades and ensure the shearing quality.

(II) Negative Feedback

1. High Maintenance Cost: Although the maintenance operation instructions are clear, some users report that the maintenance cost of JQMT shearing machines is relatively high. For example, the lubricating oil recommended by JQMT is relatively expensive, and the replacement cost of some components is also high, which increases the operating cost of enterprises in the long - term use process.
2. Highly Specialized Maintenance Tools: Some maintenance tools are highly specialized, and it is difficult to purchase substitutes on the market. Once these specialized tools are damaged or lost, it will bring inconvenience to the maintenance work and may even lead to the situation where the equipment is shut down waiting for the tools.

IV. Feedback on Fault Conditions

(I) Positive Feedback

1. Clear Fault Prompt: When the shearing machine malfunctions, such as blade jamming or abnormal noise during operation, the equipment usually gives a relatively clear fault prompt. This helps operators quickly locate the problem and take corresponding solutions in a timely manner, reducing production delays caused by too long fault - troubleshooting time.
2. Effective Fault - solving Reference: The solutions provided in the equipment manual for common faults are relatively effective. For example, when the blade jams, checking aspects such as blade wear, material suitability, and the transmission system as prompted by the manual can often solve the problem smoothly, reflecting JQMT's consideration of users' actual operations in product design.

(II) Negative Feedback

1. High Fault Occurrence Frequency: Some users report that although the fault - solving methods are effective, the frequency of equipment failures is relatively high. Especially in the case of continuous high - intensity operation, problems such as blade jamming and abnormal noise occur relatively frequently, which has a greater impact on production efficiency.
2. Difficulty in Handling Complex Faults: For some complex faults, even with fault prompts, ordinary operators find it difficult to solve them on their own. Moreover, after contacting JQMT's technical support, the time for maintenance personnel to arrive on - site is sometimes long, resulting in the equipment being shut down for a long time and causing significant economic losses to the enterprise.

V. Feedback on Safety Performance

(I) Positive Feedback

1. Reasonable Safety - Protection Design: The basic safety - protection design during the operation of the shearing machine has been affirmed by users. For example, during the operation of the equipment, the protective measures for the blades and transmission parts can effectively prevent operators from accidental contact, reducing the probability of safety accidents.
2. Practical Emergency Stop Button: The emergency stop button is set in a prominent position, and it can respond quickly in case of sudden dangerous situations, promptly stopping the operation of the equipment and avoiding the further expansion of accidents, thus ensuring the safety of operators.

(II) Negative Feedback

1. Insufficient Safety Warning Signs: In some key parts of the equipment, the safety warning signs are not obvious enough or the quantity is insufficient. For example, near some high - temperature parts at the rear of the equipment, there are no clear warning signs to remind operators, posing certain safety hazards.
2. Lack of Safety Training Materials: Although the equipment itself has certain safety performance, users indicate that the relevant safety training materials are not complete. There are no detailed instructions on safety precautions in some special operation scenarios, which is not conducive to operators' comprehensive understanding and mastery of safety operation specifications.
