CNC horizontal floor type boring mills with RAM<br />
PR <strong>150</strong>, PR <strong>160</strong>, PR <strong>200</strong>, PR <strong>250</strong><br />
These machines <strong>pr</strong>ovide heavy duty milling, finishing and 5-side machining of large and heavy workpieces by integration of<br />
floor plates, rotary, traversing and tilting tables and automatic accessory or heavy tool changing via pick up stations. The<br />
machining envelope can be configured up to 40 m (131’ lengthwise) by 10 m (32.8’ vertical) with rotary table loads up to <strong>250</strong> t.<br />
Classification<br />
P = floor type<br />
C = with automatic tool changer<br />
R = with RAM<br />
<strong>150</strong>, <strong>160</strong>, <strong>200</strong>, <strong>250</strong> = diameter of the boring spindle in mm<br />
Example: PCR <strong>200</strong> = floor type boring mill with automatic tool changer and RAM; boring spindle diameter <strong>200</strong> mm<br />
Main features<br />
• completely closed hydrostatic guiding<br />
system for guidance and movement<br />
of RAM<br />
• compensation of machine geometry by<br />
using a load-dependent regulated<br />
hydrostatic guide<br />
• extremely stiff, double-walled, heavily<br />
ribbed column<br />
• different ways of drop-compensation for<br />
Z-axis<br />
• nitrided, axial adjustable boring spindle<br />
with hardened spindle insert
