Bailipower PBM Series Three-Station Busbar Processing Machine | How to Choose the Right Model

Professional Solutions for Different Busbar Processing Requirements

In electrical equipment manufacturing, selecting a busbar processing machine is not only about choosing the highest capacity model.

The most important factor is whether the machine capability matches the actual production requirements.

An undersized machine may not meet processing requirements.

An oversized machine may increase investment costs without providing additional value.

At Bailipower, we always follow one principle:

Help customers choose the right busbar processing machine. Help customers use it better.

The PBM Series Three-Station Busbar Processing Machine is developed by Bailipower for copper and aluminum busbar processing applications.

The machine integrates three main processing functions:

• Cutting

• Punching

• Bending

One machine can complete multiple busbar processing operations, improving production efficiency and reducing manual handling.

The PBM Series includes:

• PBM-303 Standard Model

• PBM-503 Medium Model

• PBM-803 Heavy Duty Model

These three models cover different production requirements from standard manufacturing to heavy-duty industrial processing.

1. What Is a Three-Station Busbar Processing Machine?

This type of equipment is commonly called:

Three-Station Busbar Processing Machine

The term "three-station" refers to three main processing areas:

Cutting Station

Used for:

• Busbar length cutting

• Material separation

Main influencing parameters:

• Maximum cutting width

• Maximum cutting thickness

• Cutting force

Punching Station

Used for:

• Circular hole punching

• Oblong hole punching

• Customized punching operations

Main influencing parameters:

• Maximum punching force

• Maximum processing size

• Punching die configuration

• Positioning method

Bending Station

Used for:

• Flat bending

• Vertical bending

• U-shaped bending

• Other forming operations

Main influencing parameters:

• Maximum bending force

• Maximum processing width

• Maximum processing thickness

• Linear displacement accuracy during bending

Although the three stations usually share:

• PLC control system

• Touchscreen interface

from a mechanical and control perspective:

the three stations are independent systems.

During actual production:

• Each station can operate independently;

• Multiple stations can work at the same time;

• There is no fixed operation sequence between stations.

Therefore, Bailipower lists the technical specifications separately:

• Cutting System

• Punching System

• Bending System

This structure provides a more accurate description of the actual machine configuration.

2. PBM Series Model Classification

Bailipower uses:

PBM

as the unified model identification for the three-station busbar processing machine series.

The numbers represent different machine capability classes.

Important:

The model class does not represent the actual pressure of one individual processing system.

A three-station busbar machine contains three independent systems:

• Cutting System

• Punching System

• Bending System

The processing capacity of each system can be different.

Therefore, the model number represents the overall machine capability level, not a single hydraulic pressure value.

3. How to Select the Right PBM Model?

When selecting a busbar processing machine, customers should consider:

• Busbar size

• Processing thickness

• Production volume

• Automation requirements

Busbar Size

Maximum width ≤160 mm

Recommended:

PBM-303

Suitable for:

• Standard distribution cabinets

• General electrical equipment manufacturing

Maximum width ≤250 mm

Recommended:

PBM-503

Suitable for:

• Medium-size switchgear

• Industrial electrical equipment production

Maximum width ≤300 mm

Recommended:

PBM-803

Suitable for:

• Large-size busbar processing

• Heavy-duty continuous production

Bailipower recommends selecting the machine according to actual production requirements rather than simply choosing the largest model.

4. PBM Series Control System Options

To meet different production requirements, Bailipower provides multiple control solutions.

Relay Control

Basic control solution.

Advantages:

• Simple structure

• Easy maintenance

• Reliable operation

• Cost-effective

Suitable for:

Users with lower automation requirements and relatively fixed production specifications.

PLC Control

Industrial standard control solution.

Advantages:

• Stable operation

• Easy parameter adjustment

• Convenient maintenance

• Suitable for long-term production

Suitable for most modern industrial environments.

CNC Servo

Enhanced dimension positioning and advanced CNC servo solutions for higher production requirements.

a. Enhanced Dimension Positioning

The enhanced servo positioning solution is mainly used for:

Busbar dimension positioning

It is designed to reduce manual measurement and improve positioning consistency. It is not an automatic feeding system.

Advantages:

• Reduces manual measurement

• Improves positioning consistency

• Improves batch production efficiency

b. Advanced CNC Servo Control

For customers with higher production requirements, Bailipower can provide more advanced CNC servo control solutions according to the specific processing requirements and machine configuration.

5. PBM Series Bending Technology

Accuracy of Linear Displacement During Bending

Many busbar machines use bending angle accuracy as a major technical specification.

However, for three-station busbar machines, the actual bending control process is:

Input busbar parameters → System calculates target position → Hydraulic system drives bending die movement → Die reaches preset position → Return

The actual control variable is:

Linear displacement of the bending die

rather than the bending angle itself.

Therefore, Bailipower defines:

Accuracy of linear displacement during bending

as the formal technical parameter.

Bending angle accuracy is provided as a reference value.

Because the final bending angle can be affected by:

• Die structure

• Busbar material

• Material springback

Linear displacement accuracy provides a more direct reflection of machine control capability.
