Rottler P69AHD CNC Cylinder Head Porting Machine
P69AHD 5-Axis CNC Multi Purpose Machining Center offers the precision and speed needed to reproduce cylinder heads with exceptional accuracy – with no handwork needed. The P69AHD also has the capability of porting intake manifolds with the same techniques used to port cylinder heads.The P69AHD has a huge high torque spindle motor that utilizes CAT40 spindle taper and the latest motor technology to give more than 3 times more torque than previous models. 
The P69AHD 5th Axis has an automatic built in brake that locks the spindle motor axis in position for heavy cutting operations such as cast iron engine block boring and surfacing plus heavy cutting when manufacturing parts from solid billet. The P69AHD is able to machine engine blocks such as boring, surfacing, line boring, lightening and additional machining requirements. With the use of RCAM - Rottler Computer Aided Manufacturing Software allows general CNC industrial machining for a wide variety of applications. The P69AHD uses the exclusive Rottler CNC Touch Screen Control Software. With standard Windows user interface and animated training, training time and learning time is reduced. Operators can take full advantage of available features that will improve operator speed and efficiency.
The PC-based single processor control system by Direct Motion is highly interactive and very responsive. It allows the machine to do complex and sophisticated functions that are only possible within the PC processor. The upgradeable software can be networked for enhanced efficiency. The Advanced DM software tools allow manipulation of port design and minimize digitizing time. This allows an operator to pick up data once and tweak the design (including hand-ported designs) as needed.
The P69AHD has very fast rapid movements and cutting speed with infinite look-a-head capabilities offering fast production times. A common V8 cylinder head can be ported in about 1.5 hour. Digitizing is done automatically on the machine using a Reinshaw probe, eliminating the need for an expensive coordinate measuring machine (CMM). All programming and operations are done directly on the Rottler P69AHD Touch Screen Control Panel. Six tool automatic tool changers are also available for "set it and forget it" operation.
