Rottler HP6A Automatic Cylinder Hone  

Hone perfect identical bores in the automatic cycle mode. The machine will straighten tapered an out of round bore conditions automatically (unattended).

Try that on any other brand machine.

Step 1. Hone the first hole, Program rough and finish pressure, set stroke feed rate and RPM for perfect cross hatch pattern, verify final size with a bore gauge, set the calibrated stop ring, the machine will repeat size every time.

Step 2. Float hone head to second hole press the auto cycle button, walk away while the machine finishes the next hole exactly the same every time...

It's really that easy. Don't believe it. Call us and get phone numbers of the many race and high performance shops that have taken the challenge and own these great machines.
Today's Standards are becoming more demanding

Progressive engine builders must be responsive to the dynamic changes in the industry. With the latest model ring seating requirements and the diverse number of block configurations, the machinist needs the versatility offered by Rottler H Series honing machines. Cylinder finish is becoming a science as the demands continue to grow. Graphical representation of the cylinder finish, such as that displayed on an Abbott-Firestone Curve, provide a qualitative analysis of the characteristics of the surface finish. The Rk family of parameters directly portrays the surface characteristics over a given sampling length. 

Another Industry First From Rottler
The HP6A is the first automated cylinder honing machine capable of operating under two automatic program modes.

1. Automatic Stone Feed Out
By setting the number of strokes per feed in conjunction with the total amount to be removed, the operator can hone a cylinder completely unattended. The feed rate can be adjusted anytime during the honing process.

2. Automatic Load Sensing
By setting the desired load pressure in conjunction with the total amount to be removed cylinders can be honed to size accurately, without the need for operator attendance. An industry first! In addition, under high speed automatic operation the machine adjusts to a desirable speed to properly finish the cylinder just before stopping. Enter the load into the computer and the machine automatically maintains this value while it finishes the cylinder.
Setting the stroke is very efficient with the use of the upper and lower limit levers. The positive feed system on Rottler HP machine ensures controlled, precise expansion of the stones.

Rottler has responded to the dynamic needs of today's engine builder by offering the simplest controlled method of finishing cylinders. Turn difficult jobs into dollars. Specific features include: 

• Independent Stroke and Spindle drives
Achieve the desired crosshatch efficiently. Stop anywhere in the cylinder.

• Digital Control Operation
Feed settings can be adjusted even while the machine is running.

• Block Clamp Arms
Rottler's superior fixturing allows work pieces without main lines to be fixtures easily.

• Infinitely Variable Speeds and Feeds
Varying the spindle rpm is as easy as the turn of a dial... set your desired operating speed.

Achieve unmatched accuracy and control with Rottler's Heavy Duty Precision Hone Head. This system not only maintains superior accuracy, but is also effective in aggressive stock removal. The Precision Hone Head was developed to provide excellent abrasive tool support and rigidity.

• Provides superior accuracy
• Fast hole geometry correction with minimal stock removal
