300mm Transformer Core Step-Lap Cutting Machine with Punching

Reliable Silicon Steel Cut-to-Length Line for High-Precision Transformer Core Manufacturing

1. Product Overview 

Maximize your transformer core production efficiency with our advanced 300mm Transformer Core Step-Lap Cutting Machine. Specially engineered for processing high-permeability silicon steel sheets, this high-performance cut-to-length line integrates precision feeding, high-speed punching, and automated step-lap cutting into a single, seamless operation. With a maximum processing width of 300mm, it is the ideal solution for manufacturing small to medium-sized distribution transformers, power transformers, and reactors. Equipped with an advanced servo control system, this machine supports standard V-notching, hole punching, and step-lap cutting functionality, significantly reducing core loss and improving the electrical efficiency of your final transformers.

Key Benefits for Your Factory:

• High-Precision Step-Lap Function: Automatically creates optimized multi-step lap joints to minimize air gaps and eddy current losses in transformer cores.

• Integrated Punching & Notching: Performs precise hole punching and miter cutting in one single pass, reducing material handling and labor costs.

• Zero-Damage Feeding: Engineered with specialized polyurethane-coated rollers to ensure the delicate insulation coating of the silicon steel is never scratched.

5. Buying Guide: How to Choose the Right Configuration

To get the most accurate quotation and ensure the machine fits your factory layout, please consider the following factors before reaching out to our engineers:

1. Your Core Design Profile: Do you require 3-step, 5-step, or 7-step lap patterns? Confirming your core design helps us optimize the PLC software control for you.

2. Hole Punching Requirements: Specify the maximum diameter and number of holes required per lamination so we can configure the correct punching tonnage and die count.

6. Frequently Asked Questions (FAQ)

Q1: Can this machine handle both CRGO and CRNGO silicon steel?

A: Yes. Our cutting line is fully capable of processing both Cold Rolled Grain Oriented (CRGO) and Cold Rolled Non-Grain Oriented (CRNGO) silicon steel sheets within the 300mm width limit.

Q2: What is the lifespan of the cutting blades, and can they be sharpened?

A: The blades are made from imported high-tungsten alloy steel (TCT). Typically, they can perform over 1,000,000 cuts before needing a regrind. They can be resharpened 5-8 times.

Q3: How long does it take to change the punching dies or cutting angles?

A: Angle adjustments are completely automated via the PLC touch screen and take less than 2 seconds during operation. Physical die changes for different hole diameters take roughly 15-20 minutes.

Q4: Do you provide overseas installation and operator training?

A: Absolutely. We provide complete English operation manuals, step-by-step installation videos. We can also dispatch certified engineers to your factory for onsite commissioning and team training.
