Improperly done or resurfacing techniques from decades ago will only propagate braking problems, expensive come backs and customer complaints. 

Industry That is Changing - Drum style brakes were primarily used when automobiles where larger and heavier but as the automotive industry changed Rotor style brakes have become the preferred method of automotive braking.

Vehicle manufactures in their attempt to increase gas mileage have continued to change the rotor design. Rotors are increasingly  smaller, lighter and in some cases are being constructed with composite metals. 

Changing the Resurfacing Procedure - technicians have been forced to give more attention to all aspects of a brake job. The last two decades have witnessed an increase in customer complaints and expensive repair come backs. 

Today's vehicles are more sensitive to vibration, pedal pulse and brake squeal. Resurfacing to original manufacture specifications are crucial to eliminating problems and complaints.

These new braking systems have changed the way we approach the resurfacing procedure, but the basics of machining braking surface are still the same.  

There are Three Goals when machining the metal braking friction surface:

·        Elimination of Thickness Variation   

        (parallelism of opposing surfaces)   

·        Elimination of Run Out      

         (perpendicular to center line or arbor / spindle ) 

·        Producing the Flattest, Smoothest Surface possible.      

          (micro finish = 10-50 micro inches)  

  1.  Bench Lathes 

     ( Rotor / Drums machined off  the Vehicle ) 

         ·        Negative Rack Cutting  

                             or

         ·        Positive Rack Cutting

    2.  On the Car Lathes 

     ( Rotor machining on the vehicle)

        ·        Hub Mounted

                      or

        ·        Caliper Mounted

Why Accu-Turn Bench Lathes?  Because of its Patented Design -

The Accu-Turn Combination Bench Lathe has become the standard by which the auto service industry measures other Lathes.  Its inspiration came from the most sophisticated milling machines on the market. Our designers couldn’t understand why the automotive lathes at the time required multiple passes to resurface when standard milling lathes are capable of removing metal in a single pass. Features like; positive rake angled tool bits, locked-in feed rates, spindle running on Timken Tapered roller bearings and cross slides on dove tail ways make this lathe perform like a hundred thousand dollar milling lathe. It is now possible to consistently resurface rotors, drums and even flywheels in a single pass without additional process of putting on a  “non-directional” finish. This lathe is capable of producing the  OEM’s  recommended 10-50 micro-inch surface finish with a single cut.

Key Features & Benifits - 

·        Built to solve Today’s Braking Problems  
– Capable of handling the Future.  

·        Single Pass Cut / Finish = 
Speed and economy of operation produces greater profit.  

·        Spindle on Roller Bearings = 
fixed tolerances that eliminate “run-out”.  

·        Positive Rake Tooling Cuts  = 
true Parallelism even cutting through “Hot Spots”.  

·        Dove Tail Stacked Ways  = 
added rigidity helps eliminate source of vibrations.  

·        Heavy Rigid Machine = 
Eliminate vibration giving superior finish surface.  

·        End of Travel Cut-off Switch = 
more productive use of time, no need to stay with machine.  

·        Flywheel capability  = 
a great potential for added profit.
