Restore Cutting Accuracy by Securing the Guide-Rail Car

Crooked or distorted cutting can occur when the car is loose on the guide rail. Correct the issue by adjusting the clearance between the car and the rail, then secure the car while pressing it firmly at both the upper and lower ends before tightening the screws. This is especially important for screen protector products, where even a 1 mm gap can cause significant shape deformation.

Documented Symptom and Cause

The documented symptom is a crooked or deformed cut. One of the main documented causes is looseness between the car and the guide rail. This looseness creates clearance that can affect the shape produced during cutting.

The issue is particularly important when cutting screen protector products because they require extremely high precision. A gap that appears small may still have a major effect: even 1 mm of clearance between the car and the guide rail can result in significant shape deformation.

How to Correct the Guide-Rail Clearance

The supported remedy is to adjust the clearance and secure the car correctly. Follow these checks and actions:

1. Check whether the car is loose on the guide rail or has clearance that may be contributing to cutting distortion.
2. Adjust the clearance between the car and the guide rail.
3. When securing the car, press it firmly from both the upper and lower ends.
4. Keep the car firmly pressed in position while tightening the screws.

Pressing from both ends before the screws are tightened is a critical part of the adjustment. Securing only one area without firmly pressing both the upper and lower ends may leave clearance that affects cutting precision.

Expected Result and Precision Requirement

After the clearance has been adjusted and the car has been firmly secured from both ends, the documented expected result is improved cutting accuracy. The car should no longer be loose on the guide rail in the way that causes cutting distortion.

For screen protector products, the adjustment must account for their extremely high precision requirement. The key verification point is that the car is firmly secured before the screws are tightened, because even a 1 mm gap can produce significant deformation in the cut shape.
