Automobile traction parts usually need to be processed using various machines to meet their complex shapes and high-precision requirements. Common machining equipment includes:

(1) Milling machine: used to process workpieces with complex shapes such as planes, curved surfaces, and grooves. It is suitable for processing various structural components of traction parts.
(2) Lathe: used for rotationally symmetrical processing of workpieces, such as turning of shaft parts.
(3) Drilling machine: used to process holes in workpieces, including positioning holes, threaded holes, etc.
(4) Grinding machine: used for precise surface processing of workpieces to improve surface roughness and dimensional accuracy of workpieces.
(5) Laser cutting machine: used for high-precision cutting and processing of plates, suitable for processing plate parts of traction parts.
(6) Stamping machine: used for stamping and forming metal sheets, suitable for producing stamped parts for traction parts.
(7) Welding equipment: used for welding and assembling parts, including spot welding, argon arc welding, laser welding machine, etc.

The comprehensive utilization of these machining equipment can meet the requirements for shape, size and surface quality of automobile traction parts, ensuring that they have good mechanical properties and reliability.

Why should you take the fiber laser cutter into consideration?

Laser cutting machine can be applied in the processing of automotive parts, such as car interiors, door frames, and various automotive components. Laser cutting machine replaces traditional mechanical blades with an invisible beam of light, offering high precision, rapid cutting, freedom from pattern limitations, automatic nesting to save materials, and smooth cutting edges. In the processing of automotive traction components, the typical materials used are 3mm carbon steel, galvanized sheet, and aluminum sheet under 5mm. Traditional processing methods involve stamping, but currently, most factories are replacing stamping with laser cutting machines, saving the cost of tooling. Laser cutting machines are gradually improving or replacing traditional metal cutting process equipment.

The standard laser cutting machine model 3015/3015H is popular in the automotive parts industry for several reasons:

High Precision

The 3015 model offers high precision cutting, which is essential for producing intricate and accurate automotive parts.


This model can handle a wide range of materials used in automotive parts, such as carbon steel, galvanized sheet, and aluminum, making it versatile for various applications.


The 3015 model provides fast and efficient cutting, contributing to increased productivity in automotive parts manufacturing.


By replacing traditional cutting methods such as stamping, the 3015 model can reduce tooling costs and material waste, making it a cost-effective solution for automotive part production.

Automation Compatibility

The 3015 model can be integrated into automated production lines, further enhancing its appeal in the automotive parts industry.

Main Advantages of 3015H Fiber Laser Cutting Machine

Junyi laser equipment is truly dust-proof. The top of the large protective shell adopts a negative pressure capping design. There are 3 fans installed, which are turned on during the cutting process. The smoke and dust generated during the cutting process will not overflow upward, and the smoke and dust will move downward to enhance dust removal. Effectively achieve green production and protect workers' respiratory health.

The overall size of Junyi laser equipment is: 8800*2300*2257mm. It is specially designed for export and can be directly installed in cabinets without removing the large external enclosure. After the equipment arrives at the customer's site, it can be directly connected to the ground, saving freight and installation time.

Junyi laser equipment is equipped with LED light bars inside, which are designed according to international first-line brands. Processing and production can also be carried out in dark environments or at night, which can extend the working hours and reduce the environmental interference to production.

The middle part of the equipment is designed with a platform exchange button and an emergency stop switch. It adopts a lean management solution. Workers can operate directly in the middle of the equipment when changing plates, loading and unloading materials, improving work efficiency.


Cost Analysis

For example,VF3015-2000W laser cutter:

Items Cutting stainless steel (1mm) Cutting carbon steel (5mm)
Electricity fee RMB 13/h RMB 13/h
Expenses of cutting auxiliary gas RMB 10/h (AIR) RMB 14/h (O2)
Expenses of protective lens, cutting nozzle Depend on the actual situation   Depend on the actual situation RMB 5/h
Totally RMB 23/h RMB 27/h

Notice:This chart is calculated based on 3015 model 2KW fiber laser cutter. If the cutting auxiliary gas is compressed air after drying treatment, the cost is the actual air compressor operation electricity fee + machine tool electricity + consumables (protective lens, cutting nozzle).
1. The electricity price and gas price in the above list are based on the prices in Ningbo, which are different in different regions;
2.The auxiliary gas consumption will vary when cutting plates of other thicknesses.


Maintenance of Protective Lens

● Cleaning Lens
It’s necessary to maintain lens regularly because of the characteristic of laser cutting machine. Once a weak cleaning the protective lens is recommended. The collimating lens and focusing lens need to be cleaned once every 2~3 month. In order to facilitate the maintenance of the protective lens, the protective lens mount adopts a drawer type structure.

● Lens cleaning
Tools: Dust-proof gloves or finger sleeves, polyester fibers cotton stick, ethanol, rubber gas blowing.

● Cleaning instruction: 
1. The left thumb and forefinger wear the finger sleeves.
2. Spray ethanol onto the polyester fibers cotton stick.
3. Hold the slide edge of the lens with left thumb and forefinger gently. (Note: avoid the fingertip touching the surface of the lens)
4. Put the lens in front of eyes, hold the polyester fibers cotton stick with the right hand. Wipe the lens gently in single direction, from bottom to top or from left to right, (Should not be able to wipe back and forth, to avoid secondary lens pollution) and use rubber gas blowing to sway the surface of the lens. Both sides should be cleaned. After cleaning, make sure that there are no residues: detergent, absorbent cotton, foreign matter and impurities.

Removal and Installation of Lens

The whole process needs to be completed in a clean place. Wear dust-proof gloves or finger sleeves when removing or installing the lenses. 
Removal and Installation of Protective Lens 
● The protective lens is a fragile part and needs to be replaced after damage. 
● As shown below, open the buckle, open the cover of protective lens, pinch the two sides of the drawer-type lens holder and pull out the base of protective lens; 
● Remove the pressure washer of the protective lens, remove the lens after wearing fingertips 
● Clean the lens, lens holder and seal ring. The elastic seal ring should be replaced if damaged. 
● Install the new cleaned lens (Regardless of the positive or negative side) into the drawer type lens holder. 
● Put the pressure washer of the protective lens back. 
● Insert the protective lens holder back to the laser processing head, cover the lid of the 
protective lens and fasten the buckle. 

Replace Nozzle Connection Assembly 

During the laser cutting, the laser head will inevitably be hit. Users need to replace the nozzle 
connector if it gets damaged. 

Replace Ceramic Structure 

● Unscrew the nozzle. 
● Hand pressing the ceramic structure so that it is not skewed and then unscrew the pressure sleeve. 
● Align the pinhole of the new ceramic structure with the 2 locating pins and press the ceramic structure by hand, then screw the pressure sleeve. 
● Screw the nozzle and tighten it properly

Replace Nozzle 

● Screw the nozzle. 
● Replace the new nozzle and re-tighten it properly. 
● Once the nozzle or ceramic structure has to be replaced, capacitance calibration must be done again.
