Introduction: This manual is arranged into sections as listed in the table of contents. It is required that the new user of the SG9A read this manual, in particular the sections concerning safety, before operating the machine. The Controls Definition and Operating Instructions chapters should be read very carefully in order to familiarize the user with the actual button pushing sequences required to carry out a job.
Introductions / Safety / Installation SG9A Manual Safety Information WARNING For Your Own Safety Read This Instruction Manual Before Operating This Machine. This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.
If the SG9A is on the same power lines that are running to other electrical equipment (grinders, welders, and other AC motors) electrical noise can be induced into the SG9A electrical system.
Introductions / Safety / Installation SG9A Manual The SG9A machines have the following areas of exposed moving parts that you must train yourself to respect and stay away from when they are in motion: WARNING Cutting Tool Area – Any operation involving hands in the tool holder, such as inspection or alignment of the tool holder or tools, changing tool holder or insert holders, tool insertion, and removal, tool holder changes, and size checking etc.
Introductions / Safety / Installation SG9A Manual Air Adjustments: Float: The float regulator is located at the rear of the spindle base on the bottom of the interconnect box. If the machine is not floating properly, it could be from too much or too little air from the regulator. Turn the regulator all the way off (full counter clockwise).
Misuse: Do not use the machine for other than its intended use. If used for other purposes, Rottler Manufacturing disclaims any real or implied warranty and holds itself harmless for any injury or loss that may result from such use.
The proper loading arrangement and location for your SG9A machine is extremely important. A slow travel (6 to 10 feet / min.) power hoist operated from either a bridge crane or a jib crane arrangement works very well.
Machine Installation 4-10 SG9A Manual Leveling the Machine: Before leveling the machine, loosen and remove the shipping brackets securing the air float Workhead. (Figures 1 & 2). The air float clamp plate bolts may need to be loosened also. Access to these bolts is gained by tilting the spindle assembly to the left and loosening the bolts on that side approximately 1 turn.
Rottler Tool Bit Sharpener When you sharpener the Rottler form Carbide bits, consists in restoring the tool cutting angle by grinding the face. To sharp the carbide bit must be fitted on the bit holder also fitted on the tool holder.
Maintenance SG9A Manual Chapter 6 Maintenance: Lubrication: .Every 40 Hours the outer spindle surface should be cleaned with kerosene or WD40. Occasionally with a light weight #10 oil. should be wiped onto the outer spindle to prevent excessive dryness. All floating surfaces should be dry and clean do not oil the surfaces, oil will cause the work heat not to float properly.
Operating Instructions / 360º Rollover Fixture SG9A Manual Chapter 7 Operating Instructions: Mounting Cylinder Heads: 360 Degree Rollover Fixtures Initial clamp height adjustments to the head trunions can be accomplished by measuring the head thickness then raising the turning clamping block assembly to the appropriate height using the clamping block acme screws.

Overhead Cam U Clamp System SG9A Manual The Quick-Clamp frame is mounted between the trunions and clamped using the clamping plates. (See Pictures) The cylinder head is then held to the frame with the swivel clamp assemblies through the appropriate head bolt holes or used the standard clamp plates.
Overhead Cam U Clamp System SG9A Manual On This cylinder head we using both style frames. Alignment and Setup: Alignment and setup applies to both the cylinder head and the machine’s floating head. The goal is to get perfectly align to the spindle centerline of the area of the head to be machined. Most machining operations on cylinder heads use the valve guide centerline as the reference point so we will use that as an example.
The pilot is selected according to the actual guide and not according to the original guide diameter or the valve stem diameter. Rottler Fixed Carbide Centralizing Pilots are manufactured from fine grain sintered tungsten carbide and are ground to a very high degree of accuracy, straightness and surface finish - designed for a life time of precision...
IMPORTANT: The centering accuracy and the machining accuracy depend on the pilot tolerance. We insist on the necessity of using Rottler Fixed pilots. No other pilots would have the necessary quality for accurate centering. Aligning Cylinder Heads which have Canted Valve Guides Install Cylinder Head.

Tapping and Seat Angle Cutting SG9A Manual While rotating the assembly tool holder/carbide tip holder, the carbide bit’s cutting edge should just touch the micrometer spindle. Once in contact with the micrometer spindle, the carbide tip should not be moved at all. If this is not observed, the cutting edge may be damaged and the resulting surface quality, when machining, will be deteriorated.
Tapping and Seat Angle Cutting SG9A Manual The capacity of the Rottler SG7 / SG8 / SG9A / SG9 associated with a complete tooling range allow working on seats of diameters between 14 and 120 millimeters (0.55’’- 4.7’’). Three tooling ranges are possible: For seats diameters between 14 and 25 mm ( 0.55’’- 1’’): tool holder BH600R1 and Mini tip holder TH1999...
Note: when machine the seat, the sleeve should be in upper position. The work head should be in float mode at all times when is on the centering mode. NOTE: It is important that the operator of the SG9A read the Control Definitions chapter in this manual before proceeding any further.
The computer must shut down its internal systems before main power is removed from it. From any screen press FILE and then EXIT button. This will shut down the Rottler program. The terminal will show the computer desktop screen.
