Repair vs. Replace

A couple questions that are commonly asked by our customers are “How do I know if I should replace my spindle?” or “How many times can one spindle be repaired?” In almost all cases, repairing the spindle is much quicker, and less expensive. As part of the repair process, we work with our customer to identify areas of concern related to the lifetime of the spindle and the failure mode. We produce a twelve page failure report each and every time as a tool to share with you the details of your failed spindle and discuss together how failures can be eliminated or reduced. Most often the repair of ...

History of FISCHER USA

FISCHER USA has a long, and strong, history in the high-speed spindle industry. To examine the history of FISCHER USA, one must look at two companies, PRECISE (USA) and FISCHER (Switzerland), that later merged. In 1941, Precise Products was founded in Racine, WI with the introduction of the Super 30 high-speed electric hand grinder to provide a more accurate solution to machine small, intricate scale models. Precise Products became The Precise Corporation and relocated to the current location of FISCHER USA in 1956. The Precise Corporation continued its growth in the PRECISE brand of small, ...

Spindle System – Cooling System

When discussing spindles, it is normal to not fully consider the sophisticated design of these products. Many people think of a spindle as a simple motor. While this may be true in some very limited cases, most modern high-speed machining spindles are made up of many high-precision components, complex internal systems, and peripheral support systems, including: High precision bearings and pre-load system High power density motors and drive system Precision-ground shaft Mechanical tool clamping system Hydraulic tool unclamping system and hydraulic supply unit Electronic sensor systems Encoder ...

What to Know About Bearings

Bearings are used in a lot of different machines and equipment, but how much do you really know about them? The general definition for bearings is that they are used to prevent metal-to-metal contact between two parts by reducing friction and constraining relative motion to only the desired motion. By that definition, we can see the importance of them in many machines, especially high-speed spindles. With over 20,000 rpm, metal-to-metal contact would lead to a large amount of wear on the various parts, which would then result in repairs and replacement. High-speed spindles almost always ...

Most Common Causes of Spindle Failure

There are several causes that can lead to the failure of a high-speed, high-performance spindle. However, the two most common causes of spindle failure that we have seen here at FISCHER USA are Vibration and Peripheral Support System Failure. As a spindle manufacturer, we know that vibration is present in any milling process. However, spindles generally experience vibrations ranging from 0 mm/s to 10 mm/s. When the vibration levels increase above normal for an extended time, the vibrations can cause damage to the various components. The component that is most often damaged due to vibrations is ...
