CX111 Tire Uniformity Machine
The CX111 can test tires for all these vehicles, and it can do it faster,
and more reliably than any competing product.

If you are looking for a well valued, highly versatile, and capable tire
uniformity testing machine, the CX111-18 will be of interest to you. 

 

This machine has deep roots in a line of machines that have proven themselves through years of use and hundreds of placements testing tire uniformity in the worldwide Rubber Industry.  In 2001 Akron Special Machinery (ASM) produced and installed the X100, the first tire uniformity machine to make use of the newly developed “X-FRAME” technology. This groundbreaking design distributes the forces of the machine evenly throughout its frame.  The X-FRAME creates a very RIGID and DURABLE machine that is extremely FAST while measuring with a high degree of ACCURACY and REPEATABILITY.

Building on the success of the X100, ASM expanded the X-Series to include the CX111 and X150 uniformity machines.  All three machines have customizable testing capabilities and all take full advantage of the “X-FRAME” technology as well as many of our other patented features.

The latest machine in the X-FRAME lineup is the CX111, which was developed in 2008 and now has many placements with several industry leading tire manufacturers.  This machine is perhaps the most versatile tire uniformity offering on the market.  It is capable of testing the tires for very small compact cars such as the Smart or the Mini-Cooper, large sedans such as a Mercedes S600, large utility trucks or even an over the road 18 wheeler.  The speed at which a CX111 can test tires is industry leading.  It is fully capable of testing, marking and sorting more than 4,000 PCR or LTR tires per day and it has measurement accuracy and repeatability that puts it into a class that also leads the industry.

A rich set of options for this machine includes bar code identity, interfaces for upper level host computers and automated material handling systems, sidewall and tread geometry using low cost point lasers or more capable line lasers, several types of marking equipment, various sorters, as well as different optimization (Grinder) choices. 

The CX111 has remote support capability.  This support facility allows the Poling Group experts to see the same user interface your maintenance associates are seeing at the machine, including all the diagnostic information.  Then, through a chat facility right on the user interface, the trouble shooting session can be directed by the Poling Group experts.  The remote support facility requires a simple Ethernet connection that allows Poling Group access to the machine through a customer supplied VPN from our Akron, Ohio data center.

The help system and manuals for the CX111 are all online right at the machine and are accessed through the machine user interface.  The maintenance and setup procedures are organized by subject categories and presented in simple step-by-step format using pictures, diagrams and text.

 
The 2011 CX111 Machine

Our new CX111-16 and CX111-18 machines are the result of 3 years of intensive product improvement.  The improvements have largely been driven by the operating experience with our prior equipment.  We listened very closely to our customers and they were telling us they wanted a machine that was able to test larger tires with the accuracy required for smaller tires and they wanted to do that faster and with a machine that was even more durable and reliable that any prior machine.  So, we made a more capable machine.  And when we saw repetitive problems with our prior equipment, we designed solutions to create a better product.  

The result is a machine that measures larger tires much better, is much faster, has greater durability and has electrical and mechanical updates that have resolved common operating problems found in prior uniformity equipment.  

The 2011 CX111 has the following advantages and improvements over our older design machines including our X75-16 machine.

  1. The new CX111 is based on the 4 post design which has proven its durability for over 40 years. The basic “X” frame design has been enhanced and improved to process the much larger tire sizes, inflation pressures and increased loads required by even our most advanced customers. Our new “CX” frame design has the spindles located on the centerline of the X frame and therefore the Centered X (CX) in the machine’s name.  This design is patented and unique to the Poling Group equipment.  The CX frame transmits the separation forces caused by the tire inflation EQUALLY to the four posts of the machine’s legs and squarely into the head casting.  The additional strength of the 4 members of the X frame and their centered position in the machine versus the 2 members and 4 inch spindle offset from centerline of the prior design eliminates the bending and eventual cracking of the lower cylinder support channels found on the original 4 post design frames.  The X design provides much greater frame rigidity than that found in our prior designs or any “C-frame” style machine.  
     
  2. The head casting of the CX111 is much more massive than prior machines thereby eliminating undesired flexing/bending/bowing when testing larger tires, and it is designed to permit easy access to the upper load cell from the top of the machine. 
     
  3. The CX111 has a patented “cartridge” designed main spindle assembly. This design allows the complete spindle assembly to be replaced in about 3 hours thereby greatly reducing machine downtime. The worn out spindle can either be returned to Akron Special Machinery for factory rebuilding or, with properly trained associates, can be rebuilt in the plant workshop. We offer a spindle exchange program as follows: If a plant has a worn out spindle, we send them a factory rebuilt cartridge assembly, they return the worn out spindle to our factory for rebuilding. We keep the remanufactured assembly and only charge the customer for the worn out parts that are replaced and the labor required to complete the factory rebuild. 
     
  4. The loadwheel ball screw on the CX111 has been changed from a rotating ball nut to a rotating ball screw. This allows the addition of a programmable oil lube system providing automatic oiling of the ball screw and nut, thereby greatly increasing the durability of the ball screw mechanism.  
     
  5. The CX111 has a new air regulation system.  The air servo 120 is a more robust and durable air regulation system.  It has a servo driven regulator that is much less prone to failure due to contaminated air supplies thereby eliminating many of the reliability and maintenance problems associated with the E to P air regulation system used on our prior equipment.  In addition, this system stabilizes to the set point much faster, thus allowing a faster load cycle, better measurement, and reduced cycle time.
     
  6. The CX111 has the same footprint as the existing D70/D70-LTX and X75 machines.  This allows upsizing the tire testing capability without sacrificing additional plant floor space.
     
  7. The CX111 has an optional machine lubrication system which greatly reduces several possible mechanical failures on the prior design which may occur due to inadequate or incorrect lubrication.
     
  8. The CX111 has updates to the AAWC stem that increase cycle life and reduce failure
     
    · 
    The channel for trapping debris so that the stem is not scored and gaulded has been cut deeper
    · 
    The number of grease grooves have been doubled and enlarged and the holes made larger
  1. The CX111 has an optionally larger AAWC which has been used in the X100 machine 
     
  2. The CX111 has an updated bead lubricator which is now in its third generation.
     
    · 
    It uses the 2 driven rollers for tire rotation from the generation 2 designs, but now each roller has its own motor and gear box thereby eliminating the coupling belting mechanism.
    · 
    The entrance conveyor, which is integrated into the luber, uses new conveyor belts which have a V-belt stabilizer to prevent belt misalignment and pulley guide damage which sometimes occurred with larger tires on the prior design.
    · 
    The lube roller has been changed to a new style roller that provides a more precise application of bead lubrication to the full range of tires sizes.
    · 
    The bar code reading capability of the luber has been enhanced, allowing the bar code to be read while lubing the tire and the tire then positioned for signature analysis with greater precision, all in a very much improved cycle time needed for single direction testing.
  1. The CX111 has a new 2 belt center conveyor which is much simpler than the prior 4 belt conveyor.  The belts have the same V-belt stabilizer used in the luber to prevent belt misalignment and pulley guide damage.
     
  2. The CX111 has a new distributed I/O architecture which allows the machine’s data signals to be isolated from the machine’s power wiring.  This allows a much better measurement capability than any prior design.
     
  3. The CX111 has the new TTOC6 controller and TDAQ data acquisition system that together provide the most cost effect, versatile, and accurate tire testing control system available.  The TTOC, the TDAQ, and a new user interface panel, completely replace the entire control cabinet and contents of the prior TTOC systems.
     
    · 
    The TTOC6 controller has new measurement algorithms called WAVEFORM VALIDATION and WAVEFORM CORRECTION.  Through 2 years of field testing, these algorithms have proven to be industry leading and valuable by providing more PRECISE and REPEATBLE uniformity measurements.
    · 
    The TTOC6 controller has new motion algorithms for tire entry, tire loading, and tire exit that along with the TTOC6 algorithms for waveform validation and correction allow tires to be tested SEVERAL seconds faster than any prior or currently competing machine. Production capacity is now really a question of how fast and steady is your supply of tires, as this machine can test, mark, and sort more than 3 tires every minute.  And, using our new waveform validation and correction algorithms it can test those tires to industry required measurement repeatability at that rate.
    · 
    The Tire Data Acquisition system (TDAQ) is a new product that is used with the TTOC6.  It replaces the chassis-based signal conditioners and ALL the PCI cards in the industrial computer that were used for analog and digital I/O in the prior TTOC systems.  The TDAQ is a much smaller footprint system with very high noise immunity that provides a set of load cell signal conditioners and a single board printed circuit system combining a digital I/O facility with high resolution 24 bit and low resolution 10 bit Analog to Digital (A/D) converters and medium resolution 16 bit analog outputs.  This CE marked system has been deployed for 2 years on many machines and has not had a single failure.
    · 
     The TOCC 6 controller, along with a CTI Final Finish Host (FFH) system, allows a customer to test non OE tires with one direction testing.   This testing method, which greatly INCREASES production capacity, uses the average PLY steer calculated by the FFH for a given tire construction (process code) to project a conicity value based on first direction lateral shift value.  If the conicity value is below a given amount (nominally 80 to 85 percent of max value), the need for the second direction can be eliminated. This advanced method of testing for trade tire uniformity is becoming standard for many of the major tire companies because of the very large increase in production capacity it provides.
  1. The CX111 has auto-adjust shoulder grinders using the original heavy-duty frame design, but updated with needle roller thrust and taper bearings replacing bushings and thrust washers that result in improved belt life and precise grinder positioning and repeatability.
