Cutting & Stripping

JMK large cable cutting and stripping machines prepare high-voltage power cables for downstream terminal crimping and connector assembly. Designed for large cross-section and multilayer cables, the equipment completes fixed-length cutting and programmable insulation stripping while reducing the physical effort and variation associated with manual cable preparation.

The JM-70 processes cables from 6 to 200 mm², supports cable diameters from 6 to 25 mm and can strip up to nine cable layers. It is suitable for high-voltage wire harnesses used in new energy vehicles, energy storage systems, charging equipment, electrical power systems and industrial controls.

Automatic Preparation of Large High-Voltage Cables

Large power cables are heavier and less flexible than conventional signal wires. Their thick insulation and multilayer construction make accurate manual cutting and stripping difficult to maintain over repeated production batches.

Our cable processing machine for cutting and stripping uses programmable control to complete the required cable preparation sequence. The operator sets the cutting and stripping parameters according to the cable specification, allowing the equipment to process repeated lengths without measuring and stripping each cable manually.

The machine can be used for:

  • Fixed-length cable cutting

  • Front-end insulation stripping

  • Rear-end insulation stripping

  • Full stripping

  • Partial stripping

  • Multilayer cable stripping

  • Large copper cable preparation

  • Pre-processing before terminal crimping

  • Small-batch and repeat production

Processing Cables from 6 to 200 mm²

The JM-70 covers a broad range of large cable specifications used in high-current electrical systems.

Processing itemJM-70 capacity
Conductor cross-section6–200 mm²
Cable outer diameter6–25 mm
Maximum front stripping length400 mm
Maximum rear stripping length250 mm
Supported stripping layersUp to 9 layers
Stripping methodCutting and peeling knife
Cutting accuracy0.1%L + 1
Production efficiencyApproximately 300–700 pieces/hour

The actual processing range and output depend on the cable construction, insulation material, cutting length and required stripping sequence.

Multilayer Cable Stripping

High-voltage cables may contain several insulation and protective layers. Each layer can have a different thickness, hardness and stripping length, so a single cutting depth may not be suitable for the entire cable.

The JM-70 supports programmable stripping of up to nine layers. This allows the cutting and peeling sequence to be adjusted according to the structure of the cable.

Typical cable layers may include:

  • Outer protective insulation

  • Inner insulation layers

  • Wrapping or separation layers

  • Conductor insulation

  • Other process-specific protective materials

The supported processing method must be confirmed using an actual cable sample. Shield braids, foils and special reinforcement materials may require a separate processing station if they cannot be removed through the machine’s cutting and peeling method.

Long Front and Rear Stripping Lengths

Some high-voltage harnesses require longer exposed sections for terminal installation, heat-shrink positioning or subsequent assembly.

The JM-70 supports:

  • Front stripping lengths up to 400 mm

  • Rear stripping lengths up to 250 mm

  • Different stripping settings at each cable end

  • Full-strip and partial-strip requirements

Separate front and rear settings provide greater flexibility when the two cable ends use different terminals or assembly processes.

Protecting the Cable Conductor

An effective automotive wire harness stripping machine must remove insulation without unnecessarily cutting or deforming the underlying conductor.

Before production, the cutting depth and peeling parameters should be tested with the actual cable. Suitable settings depend on:

  • Cable outer diameter

  • Conductor cross-section

  • Insulation thickness

  • Insulation hardness

  • Number of cable layers

  • Conductor construction

  • Required stripping length

  • Full-strip or partial-strip process

The first processed samples should be inspected for strand damage, incomplete stripping, insulation marks and inconsistent exposed length before batch production begins.

Preparing Cables for Terminal Crimping

Cutting and stripping are the first stages of high-voltage terminal assembly. After preparation, the cable can move to a suitable crimping station for terminal installation.

Customers processing large copper terminals can connect this workflow with JMK high-voltage terminal crimping machines.

A typical production sequence may include:

  1. Cable feeding and measurement

  2. Fixed-length cutting

  3. Front-end stripping

  4. Rear-end stripping

  5. Conductor inspection

  6. Heat-shrink or number tube loading

  7. Terminal positioning

  8. Heavy-duty terminal crimping

  9. Crimp inspection and testing

Keeping cutting and stripping parameters consistent helps reduce variation during subsequent terminal insertion and crimping.

Applications

The JM-70 cable processing machine for wire harness production is suitable for large power cables used in:

  • Electric vehicle power distribution

  • New energy vehicle wiring harnesses

  • Battery and energy storage systems

  • EV charging piles

  • Charging guns and charging cables

  • Photovoltaic power systems

  • Electrical control equipment

  • Industrial power distribution

  • Heavy-duty electrical assemblies

Machine suitability should be determined from the cable construction and required process rather than the application name alone.

When to Use an Independent Cutting and Stripping Machine

An independent cutting and stripping machine is suitable when manufacturers need flexibility across different downstream processes.

It may be preferable when:

  • Different terminals are crimped on the same cable type

  • Crimping is performed on several separate presses

  • Production includes frequent terminal changes

  • Some cables require cutting and stripping only

  • The factory already has suitable crimping equipment

  • Production batches vary in length and specification

  • Manual downstream assembly is still required

For stable, high-volume products that require cutting, stripping, tube processing and crimping in one continuous system, the JM-700 high-voltage wire harness production line may be more suitable.

How to Select and Configure the Machine

Please provide the following information before equipment selection or sample testing:

  • Cable conductor material

  • Conductor cross-section

  • Cable outer diameter

  • Cable construction drawing

  • Number and thickness of insulation layers

  • Insulation materials

  • Required cutting length

  • Front stripping length

  • Rear stripping length

  • Full-strip or partial-strip requirements

  • Required production capacity

  • Downstream terminal and assembly process

Physical cable samples are important because cables with the same nominal cross-section may have different diameters, insulation hardness and internal structures.

FAQs

What cable sizes can the JM-70 process?

The stated processing range is 6–200 mm², with supported cable diameters from 6 to 25 mm. Actual suitability depends on cable construction and insulation material.

Can the machine strip multilayer cables?

Yes. The JM-70 supports up to nine stripping layers under suitable cable and process conditions.

What are the maximum stripping lengths?

The maximum front stripping length is 400 mm, while the maximum rear stripping length is 250 mm.

Can it perform partial stripping?

The cutting and peeling system can be configured for suitable full-strip or partial-strip processes. Actual cable samples should be tested before production.

Does the machine trim and fold shielding braids?

Shield braid trimming and folding are not listed as standard JM-70 functions. Cables with braided or foil shields should be evaluated to determine whether additional equipment is required.

Does it include CCD inspection?

CCD inspection is not currently listed as a standard JM-70 function. Processed cables should be inspected according to the customer’s conductor-damage and stripping-quality requirements.

Can it connect directly to a crimping machine?

The JM-70 is presented as an independent cutting and stripping machine. For an integrated cutting, stripping and crimping process, JMK can evaluate a complete high-voltage production line.

What samples are needed for testing?

Please provide complete cable samples together with the cable drawing, cutting length, stripping dimensions and downstream terminal assembly requirements.
