Frequently Asked Questions
What thickness and hole diameter can the LS 20 achieve?
See "Punching capacity" and "Hole diameter" in the technical table: typically 3 to 20 mm holes in sheet metal up to 8 mm.
Capacity refers to mild steel S235JR. For stainless steel and hardened steels, reduce the maximum thickness by 30-40%. For shaped holes or over Ø 20 mm, consider hydraulic punch presses.
Is punch and die changing quick?
Yes, professional Bernardo models (e.g., LS 20) have quick punch and die changes to increase productivity in series production.
For efficient production, it is advisable to keep the most commonly used punches in stock. Krollit supplies original Bernardo spare parts for all standard diameters.
Does it have a stop for series drilling?
Professional models are equipped with an adjustable stop for repetitive series drilling.
The stop provides repeatability of hole position on multiple pieces, reducing marking times and improving accuracy on modular components.
What is the useful throat capacity?
See "Throat" in the technical table: typically 160 mm for bench models, up to 300+ mm for industrial models.
The throat is the distance between the edge of the sheet metal and the punching point. A larger throat allows punching in the center of wide sheets.
Does it require fixed installation?
Bench models can be fixed to a robust workbench; industrial models require a dedicated base.
For intensive use, rigid fixing to a steel bench or floor is recommended. Krollit provides technical documentation for correct installation.
