What are the best solutions for managing fluids in spindles?

An interview with Petr Vozábal - Engineer and Technical Manager in the Machine Tool industry

We asked Petr Vozábal - from Vopss, a company specialised in machine tool maintenance - "What are the best solutions for managing fluids in spindles?" He has no doubts; the anwer is ROTARY JOINTS from Kadant Johnson

.

WHY IS THE ROTARY JOINT CONSIDERED A CRITICAL COMPONENT IN THIS APPLICATION?

.

"The operation of the complete spindle is directly related to the perfect functionality of the rotary joint. Under all conditions, the rotary joint must allow proper cooling for the machine tool spindle, which is the most stressed and worn part. In modern machines, a malfunction of the rotary joint could cause damage to the entire system, and completely repairing the damaged part can be very costly."

.

WHAT ARE THE MAIN FEATURES OF JOHNSON-FLUITEN ROTARY JOINTS PROVIDED BY KADANT?

.

"The main feature of Johnson-Fluiten rotary joints for us is reliability. As we have said, the component plays a small but crucial part in the economy of the whole machine, it has to be a guaranteed component, it has to inspire 'confidence' when you mount it on a modern spindle. We did a job on a machine that had a problem with the rotary joint, and repairing all the parts involved in the failure cost the customer between 14.000 and 40.000 EURO, according to the spindle / machine type"

.

A RISK THAT IS NOT WORTH TAKING SINCE, IN ADDITION TO THE COSTS OF REPAIRING AND RESTORING THE MACHINE, THE COST OF LOST PRODUCTION MUST ALSO BE CONSIDERED... HOW DO YOU PROCEED WITH THE CUSTOMER WHEN WORKING ON MODERN MACHINE TOOLS?

.

"Mainly, our job is to restore the perfect functionality of the machine tool that the customer uses. But we do not stop there... very often our work also aims at raising the overall quality, in other words optimising the spindle's performance; in this way the customer can produce more, faster and with less machine downtime."

.

WHICH KADANT PRODUCTS DO YOU PREFER FOR SPINDLE MAINTENANCE? AND WHAT SPECIFIC BENEFITS HAVE YOU EXPERIENCED BY USING THEM?

.

"We have been working with KADANT for almost 10 years now, and the rotary joints we use most are the GFLA and GHP manufactured by Johnson-Fluiten. The choice of these two components has proven to be a winner in many ways; of course in terms of quality they represent the top worldwide, but it is not just a matter of safety and reliability..."
