Rottler’s Next Generation 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 EM69P also has the capability of porting intake manifolds with the same techniques used to port cylinder heads.

The EM69P has a huge high torque spindle motor that utilizes CAT40 spindle taper and the latest motor technology to give more torque than previous models.
The EM69P 5th Axis has a proven 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 EM69P 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 EM69P 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 EM69P features the new 4C PC-based single processor control system by Direct Motion is highly interactive and very responsive. Our next generation 4C control system extends capability to include importing of CAD models which can be automatically be converted in toolpath that the machine can then use to execute actual machining operations. 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.

Standard Equipment. High Torque 18ft.lb (24Nm) @ 1000RPM High Torque Liquid Cooled Integral CAT40 Taper Spindle Motor. Optional High Speed Spindle Motor available for increased speed and output up to 25,000RPM

The EM69P 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 EM69P 32” Touch Screen Control Panel.

The 24 tool automatic tool changer is included as standard equipment for "set it and forget it" operation.

New SG9MTS MANUALMATIC Touch Screen Control Seat & Guide Machine

The SG9MTS uses the same proven patented UNIPILOT tooling as SG9M..

The machine have 2 modes of operation:

1. MANUAL – the buttons on touch screen are the same as the previous SGM machines. There is no external dial gage, the spindle vertical position is displayed on the touch screen. Simply feed the spindle down until the cutting insert touches the valve seat, touch set zero button and then the digital display will show exactly where the spindle is at all times. The change from low to high/finishing speed is easier as there are 2 separate buttons. The foot pedal for clamp and float of workhead has been eliminated and now controlled on touch screen for manual and automatically for MANUALMATIC.

2. MANUALMATIC – a brand new concept has been added to these machines which should increase productivity by 30-50%. During seat cutting, the operator does not have to operate any buttons or switches, simply turn the spindle feed steering wheel up and down and the control takes care of all the functions like workhead float/clamp, pilot centering in the valve guide and spindle on/off. When depth of seat is reached, the control automatically changes spindle RPM to high/finish speed to give equal depth of every seat and consistent surface finish results.

The Rottler SG9MTS spindle is mounted on a sphere which allows the UNIPILOT to automatically center with the valve guide centerline while the Workhead is floating on air cushions. Once air floating stops and the Workhead clamps, the UNIPILOT and valve guide centerline are maintained while cutting the valve seat.

• ACTIVE SPINDLE - Spherical Pneumatic Automatic Alignment System built into the Spindle for fast location of the pilot into the Valve Guide and Accurate Centering (Patent Pending)
• Air Float Work Head with Foot Pedal Control
• Heavy Duty Spindle - Diameter 3.150” (80mm) Hardened and Ground with 8” (200mm) of hand wheel vertical travel.
• Rottler Automatic Tightening and Quick Release Spindle Lock Nut System for One Hand Operation for fitting and removing tooling to and from the spindle – never comes loose!

Gives Best Concentricity
Rottler's Rigid Precision carbide centering UNIPILOTS are manufactured to less than one tenth (.002mm) tolerance.

Combined with the light weight air float Workhead the SG9 gives perfect centering in the valve guide and the best concentricity of any machine on the market, .0005” per 1 inch of valve diameter (.01mm per 25mm Dia.).
