Glass cutting machine usage and maintenance guide
2025-07-18
Glass cutting machineis a tool specially used for cutting glass. It is widely used in the construction, furniture, electronics, automobile and other industries. It can accurately cut glass of different thicknesses and sizes. It is a key equipment in the Glass Processing process. The following is a detailed description of the equipment, usage and maintenance tips:
1. Introduction to glass Cutting Machine
Basic composition
It is mainly composed of a cutting head (including diamond or carbide cutter wheel), a guide rail, a positioning device, a pressure adjustment system and an operating table. Some high-end models are also equipped with a CNC system for automatic cutting.

Classification
Manual glass cutting machine: It relies on manual operation, is suitable for small batches and simple shapes, has low cost and strong flexibility.
Semi-automatic glass cutting machine: It combines manual positioning and mechanical drive cutting, and its efficiency is higher than that of manual models.
CNC glass cutting machine: It controls the cutting path through computer programming, has high precision (the error can be controlled within 0.1mm), and is suitable for complex patterns and mass production, such as automotive glass and electronic display glass cutting.

Scope of application
It can cut ordinary flat glass, tempered glass (special tools are required), laminated glass, insulating glass, etc., with a thickness of usually 1-20mm. Special models can cut thicker glass.

2. How to use the glass cutting machine
Preparation before use
Check the equipment: make sure the guide rails are clean and free of debris, the cutting head wheel is intact (no wear or cracks), and the pressure adjustment knob is flexible.
Glass pretreatment: clean the glass surface (remove dust and oil) to avoid scratches during cutting; mark the reference line on the glass according to the cutting size.
Adjustment parameters: adjust the cutting pressure according to the thickness of the glass (the thicker the thickness, the greater the pressure, such as 5mm glass pressure is about 0.3-0.5MPa), and calibrate the verticality of the cutting head and the glass surface.

Operation steps
Positioning the glass: Place the glass steadily on the operating table, align the reference line, and fix it with a clamp (to prevent sliding).
Cutting operation:
Manual model: Hold the cutting head and move it at a constant speed along the marked line to ensure that the cutter wheel is in close contact with the glass surface and the force is uniform (avoid incomplete cutting due to too light a force and glass shattering due to too heavy a force).
CNC model: Input the cutting path parameters in the control system, start the equipment, and the mechanical arm automatically completes the cutting. During the process, the operating status of the equipment needs to be observed.
Glass separation: After the cutting is completed, tap the edge of the glass along the cutting line to use the stress to break the glass along the cut; if the break is not neat, it can be trimmed with an edge grinder.

Precautions
Operators need to wear protective glasses and gloves to avoid scratches from glass fragments.
Keep the environment dry during cutting to avoid water or oil stains affecting the cutting accuracy.
It is forbidden to cut glass that exceeds the maximum thickness of the equipment to prevent damage to the cutter wheel and guide rail.

3. Maintenance tips for glass cutting machines
Daily maintenance
Cleaning: After daily operation, wipe the guide rail and cutting head with a soft cloth to remove glass debris and dust; clean the cutter wheel with alcohol regularly to avoid oil accumulation affecting the cutting effect.
Lubrication: Add lubricating oil (such as vaseline or special machine oil) to the guide rails, bearings and other moving parts every week to reduce friction loss.

Regular inspection and maintenance
Cutter wheel: Check the wear of the cutter wheel after cutting 500-1000 meters of glass. If there is a gap or passivation, replace it in time (the life of the diamond cutter wheel is about 10,000-30,000 meters, and the alloy cutter wheel is about 3000-5000 meters).
Pressure system: Check the pressure regulating device every month to ensure stable pressure. If leakage or abnormal pressure is found, repair the seal in time.
CNC system: Back up the program regularly, clean the dust of the control system, and avoid moisture or high temperature affecting the circuit components.
