Frequently Asked Questions

Q What is the maximum slitting speed of the SH-1000 and SH-1250 silicon steel slitting machines?
Both the SH-1000 and SH-1250 models support multiple slitting speed options: 0-60m/min, 0-90m/min, and 0-150m/min, with an overall maximum capability of up to 250m/min, allowing flexible adjustment based on production requirements.
Q What material thickness range can these slitting machines handle?
Both the SH-1000 and SH-1250 models are designed to process silicon steel coils with a material thickness ranging from 0.20mm to 0.5mm, including ultra-thin sheets as thin as 0.18mm, without compromising the material's magnetic performance.
Q How precise is the slitting width accuracy on these machines?
The slitting width error is controlled to within ±0.1mm, and with Siemens PLC control, the width error can be further reduced to ≤0.05mm. The slitting burr is kept at ≤0.02mm, ensuring high-quality strip edges suitable for transformer and motor applications.
Q What industries are these silicon steel slitting machines suitable for?
These machines are widely used in transformer manufacturing, motor production, electrical equipment fabrication (inductors, reactors, electromagnetic switches), and the power equipment industry. They are ideal for any application requiring precision-cut silicon steel strips.
Q What is the difference between the SH-1000 and SH-1250 models?
The main differences lie in material roll width, weight capacity, and slitting strips. The SH-1000 handles up to 1000mm roll width with a 5T weight and 10 slitting strips, while the SH-1250 supports up to 1250mm roll width with an 8T weight and 12 slitting strips. The SH-1250 also requires higher installing power (45kw/65kw/100kw vs. 35kw/55kw/85kw).
Q What key components ensure the long-term reliability of these slitting machines?
The machines are equipped with durable alloy knives that resist wear and maintain consistent cutting quality over time. The hydraulic system uses YUKEN components for reliable and stable operation. Siemens PLC control and EPC alignment systems further enhance automation and reduce the need for manual intervention.
