Shaft renovation: Long live the spindle!

The spindle shaft, the spindle housing, the drawbar, the spindle bearings and the gripper – these mechanical parts form the crucial basis when it comes to the accuracy and service life of your spindle. Some of these parts, such as the spindle bearings, are wearing parts that we replace with new ones. For other components, we thoroughly refurbish them as part of the shaft repair process. The result? Lower costs, but not a lower quality spindle.

When renovating shafts, we benefit from the know-how of our sister company kptec precision parts. Over the last few decades, the company has built up its expertise as a result of manufacturing well over 100,000 shafts, drawbars and housings. When it comes to measuring and assessing taper angles, plane surfaces and clamping slopes, tolerances within the micron range require the utmost precision. kptec precision parts has the knowledge and technical equipment to measure the relevant dimensions and tolerances in the interfaces and to process them accordingly. That is our advantage – and yours too!

The majority of the work is carried out here in-house. Laser welding and grinding work is performed by experienced professionals. This means that we are always in control of the dimensional accuracy of the shaft renovation ourselves. Using our extensive machine park, we process spindle parts with a diameter of up to 400 millimetres and a length of up to 1,200 millimetres. In special cases, we will also utilise the cryogenic treatment method provided by kptec cryo in order to, for example, improve the dimensional stability and wear resistance of the components.

If specialist know-how is required to solve a task, we will work with proven partners who, for example, will coat damaged and pre-ground surfaces using the HC or HVOF process, thus improving the hardness and structure of the parts‘ surfaces. With this increased protection against wear and corrosion, your spindle is given the best opportunity to function precisely and for a long time.

„The heart of the spindle – the spindle shaft – demands the highest standards of both man and machine when it comes to the manufacturing process. I take on the challenge of producing micron tolerances every single day so that our customers can keep on receiving spindles that run in a highly precise fashion.“
