There post-collision management<\/b> requires a technical-scientific verification protocol. CIIP Cavallari<\/a> intervenes promptly to assess the extent of the damage and proceed with the restoration of the original geometries on lathes and work centres of all brands (Mazak<\/a>, Okuma, Mori Seiki<\/a>, Doosan, Biglia), ensuring that the machine returns to production in complete safety.<\/p>\n

In a high-productivity machine shop, a machine tool crash or collision is unfortunately a possible event. A programming error, an incorrect tool offset, or a careless workpiece positioning can cause violent collisions between the spindle, the turret, and the machine structure. Beyond the initial fright, the real problem lies in the <\/span>invisible damage<\/b>: even if the machine appears to be working, an impact can irreparably compromise the precision and useful life of the components.<\/span><\/p>\n

What to do immediately after a collision?<\/b><\/h2>\n

The first instinct after a crash is to reset the alarm and try to move the axles. <\/span>This is the most common and dangerous mistake.<\/b> Before putting the machine back into operation, it is essential to follow these steps:<\/span><\/p>\n

    \n
  1. Immediate stop:<\/b> Don't force the movements.<\/span><\/li>\n
  2. Visual inspection:<\/b> Check for oil leaks, cracks in castings, or obvious signs of turret movement.<\/span><\/li>\n
  3. Check the motor load:<\/b> If the axle motors show abnormal current draw when idling, the mechanics are misaligned or forced.<\/span><\/li>\n<\/ol>\n

    A professional technician can prevent damage costing just a few hundred euros from turning into a broken ball screw or motor after just a few hours of hard labor.<\/span><\/p>\n

    The CIIP Cavallari recovery protocol<\/b><\/h2>\n

    When we respond to a car crash, our technical staff performs a series of metrological checks to map the consequences of the impact.<\/span><\/p>\n

    1. Checking the Turret Alignment (Lathes)<\/b><\/h3>\n

    In lathes, the turret is the most exposed component. An impact almost always moves it "off-axis." We check the centering with respect to the spindle and the squareness. If the turret is rotated, the tools will work off-center, causing breakages and out-of-alignment parts. We proceed with mechanical realignment and resetting the centering pins or Hirth joints.<\/span><\/p>\n

    2. Spindle Geometry Control<\/b><\/h3>\n

    The spindle experiences the impact energy through the bearings. We measure the <\/span>run-out<\/b> (the eccentricity) of the spindle shaft. A violent impact can cause the bearings to brinell: micro-marks that will generate vibrations and heat over time. We also check that the machine head has not moved relative to the base.<\/span><\/p>\n

    3. Integrity of the Kinematic Chain (Screws and Guides)<\/b><\/h3>\n

    The kinetic energy of a collision is transferred to the ball screws. Let's verify:<\/span><\/p>\n
