Hydraulic control valve spool bores are complex and require high precision. Single‐blade reaming with subsequent honing is the most common machining method. The challenge is to reduce machining time and maintain tolerances.
Multi‐bladed RX reaming tool with guide pads from URMA guarantees maximum feed rates. Thanks to the quick‐change system, the cutting edges can be changed within a very short time – without removing the tool from the machine or making any adjustments. In the case of hydraulic control valves with larger manufacturing tolerances, subsequent honing can even be dispensed with completely.
We will explain in a nutshell what you always wanted to know about special reaming tools with guide pads.
