Product Details

Die clearance too small- Clearance can be proper clearance or tight clearance. In proper clearance fracture lines meet, punching forces are balanced. In general, shear strength determines clearance (10% is good for low shear strength aluminium). The recommended minimum die clearance is 0.08mm. In tight clearance fracture lines do not meet, secondary shear cracks, extra energy is required and involves higher tool wear. Poor or no maintenance on the tool- Proper tool maintenance results in flatter sheets, cleaner holes, less stress on tool and machine, longer tool life and maxima coating is not affected. To maximize tool life sharpen frequently, use proper die clearance and shear configuration, lubricate punch, guide and sheet, inspect tool holders for wear, treated tools should be used for special applications, radii should be used on all sharp corners, turret alignment should be checked regularly. Turret alignment requires adjustment- Thick turret alignment tools include mate pilot alignment system, standard alignment tool.
