Hennig chip conveyors on Niigata machining centers maintain efficiencies and production on ductile iron castings used in heavy truck and military drive train projects at Michigan shop  

_MG_2434rtMachesney Park, Illinois – Accurate Gauge prides itself on the company motto that says, “The quality is not in the product, unless the quality is in the process.”  As this busy Rochester Hills, Michigan machine shop can attest, the machining and assembly of large ductile iron castings into components for the heavy truck and military drive train markets is one that demands accuracy at every turn.  Correspondingly, the heavy-duty manufacturing equipment here includes a line of Niigata SPN 701 horizontal machining centers (HMCs) with multiple pallets, used for machining very large, heavy workpieces with  accuracy that ranks among the highest in the machine tool world market. As a result, Accurate boasts the industry leaders among its customers, including Meritor, Axle Alliance, Dana and Mack.

The shop machines over 98% of its workpieces from ductile iron and the iron sludge build-up in the coolant tank is an all too familiar problem for the production personnel.  As Accurate’s engineering manager Mark Tario explains, “We approach every machine with a keen eye on machine uptime and an absolute ease of maintenance.  We had experimented with other systems to handle cast ductile iron fines and knew their benefits as well as their shortcomings.” Mark notes the company had actually designed two systems in-house to improve the handling of chips and the cleaning of coolant.  While the benefits had been appreciable, they felt there was still a shortfall and the team at Accurate began a systematic search for a better solution.

_MG_2364rt

One of the potential vendors, Hennig, was an established force in the market, as the company’s chip conveyors and machine enclosures are found on many of the global machine tool builders’ equipment.  A particular development from Hennig caught the attention of the team at Accurate, namely, a magnetic chip disc filtration system that represented a substantial improvement over the traditional drum screen filtration system used on most competing brands.  The relative ease of changeover immediately impressed the Accurate engineers, both from the production and maintenance perspectives.  As Mark explains, “Replacing the drum filter screens is not an easy task, in fact it can be downright miserable.  The Hennig disc arrangement seemed to us a much easier system to operate and maintain.  The incorporation of a rare earth drum & scraper assembly inside the conveyor appeared to be a great solution for minimizing the amount of cast iron fines reaching the coolant tank side of the system.”  Mark notes the heavier-duty mechanical components and drive chains used on the Hennig conveyor were also impressive, providing a greater wear life and reduced downtime likelihood.

_MG_2280rtAn initial order was placed with Hennig for four Chip Disc Filtration (CDF) conveyors to run in tandem with the Niigata machines.   All electrical controls, coolant tanks, pumps and other hardware were provided by Hennig.  Mark and his team worked closely with the Hennig mechanical and electrical engineers, as well as the Hennig’s local representative, John Kaczmarek of Marathon Industrial Sales in Sterling Heights, Michigan, to complete the first installation.  “We have over 40 years of experience in what works and what doesn’t in the machining of cast iron, so we had a very defined list of needs in all facets of the design, electrical functions and the very important aspect of machine to auxiliary equipment communication,” Mark notes, adding that the worst scenario in the shop occurs when the machining center is working, but the chip conveyor is not.

_MG_2418rt

Every aspect of the machine-to-conveyor connection was planned out by the Accurate team, including the layout of the coolant tank covers and the access ports.  This attention to detail is something in which the company takes great pride.  “The Hennig team was very good on this job and they realized that nothing less than their best efforts would satisfy us,”   Tario notes.

Among the many issues Accurate had to overcome, downtime for maintenance was the most prominent.  The machining of cast iron, by definition, creates considerable problems arising from the frequent need to replace conveyor chains, drum screens and other mechanical components that get infiltrated by the iron fines and literally lock up.  The conveyor chains on the Hennig system, for example, were found stronger than the typical styles used on competing brands, which often required adjustments and repairs several times annually and were usually in need of total replacement, once a year.   Depending on the severity of the repair or replacement operation, this situation resulted in many hours or even several days to rectify.  Practically speaking, the maintenance personnel would get completely soaked and filthy with the coolant and sludge as a result.

_MG_2264rtOn the Hennig CDF system, by contrast, the discs can be easily removed and cleaned on a workbench, rather than reaching through narrow access ports to wrestle with a drum style filter.  According to Mark, this entire process is a two-hour operation at most.  Simple screen replacements can be done in thirty minutes or less, he notes.

Another common problem for the maintenance personnel are coolant related failures.  On the HMCs at Accurate, a substantial amount of “through the spindle coolant” is used to improve productivity.  However, this generous use of coolant can create an immediate and dangerous problem, if the coolant runs low and the machine has no safeguard-warning device, especially when drilling and tapping.  Nearly half the Accurate systems had no such devices originally, resulting in some damage conditions on the high-speed drills used here.  A third of the later systems used at the company had a communication device to put the machine’s CNC into a single block state when the coolant tank ran low, but had no protection to shut off the pump to prevent dry running.  Mark notes, “On our third generation systems, we changed from a diaphragm style pump to a screw pump, where dry running would be very bad, to say the least.  With our fourth generation Hennig conveyors, however, we have all the protections of the previous generations plus all the necessary controls to shut down the pumps to prevent very costly system component damage.”

_MG_2295rt

Accurate has already installed four Hennig systems, just received an additional three and has plans to purchase two more shortly, for a total of nine in the shop.  All are connected to Niigata HMCs that have an opening in the back of the machine with a horseshoe-shaped channel where the conveyor fits.  The overall machine size is 10’ wide by 30’ long.

Other Accurate personnel involved in this project who contributed to the story include Greg Mann, plant manager, Dennis Shepp, maintenance technician and Jim Weeks, shift supervisor and maintenance technician.

Hennig custom enclosures and fuel tanks provided for three Cummins 2MW generators at Broken Arrow, Oklahoma project for Cummins Southern Plains LLC

Broken Arrow WTP 004rtMachesney Park, Illinois – The City of Broken Arrow’s only existing water treatment plant, erected in 1966, could no longer satisfy the needs of the 35,000 homes and businesses, requiring the City to purchase water from other facilities and nearby Tulsa.  In cooperation with the Oklahoma Department of Environmental Quality and the Oklahoma Water Resources Board, a new municipal water treatment plant on the shore of the Verdigris River will provide up to 20 MGD (plant rating at 20 degrees C) of water daily to the City of Broken Arrow, Oklahoma.

The project began in early 2012 with the bid for the standby power system awarded to Cummins Southern Plains LLC, Tulsa, for the parent company based in Arlington, Texas. The project will utilize three 2 MW generators powered by Tier II emission certified Cummins 16 cylinder QSK 60 series diesel engines.

Due to the environmental and acoustic specifications of the water treatment facility, special enclosures and fuel tanks for the generator sets were required. Cummins Southern Plains LLC sales representative Mike Teague asked Hennig Enclosure Systems (Machesney Park, Illinois) to provide a possible solution. As Mike explained, “Al Grabowski from Hennig had been in contact with Cummins Southern Plains. We gave him the opportunity to quote the project and were quite pleased with the results.”

Cummins Southern Plains LLC provided the performance characteristics of the generator sets to Hennig Enclosures Systems, who then provided submittal drawings of the enclosure packages in Solid Works CAD format for the customer to review. Each enclosure measured 40’ long x 10’ wide and nearly 14’ high to allow ample airflow and provide a 25 dba sound reduction.  After the customer and contractor approved the drawings, Hennig Enclosure Systems began cutting and bending steel.  “Hennig is a one-stop shop. We manufacture the entire enclosure and fuel tank in addition to mounting the genset and landing all the electrical connections for the customer,” Grabowski added.

The Hennig solution involved a topcoat finish of TGIC polyester powder coat paint for weather resistance and UV protection.  Grabowski notes, “Hennig utilizes a durable powder coat finish along with stainless steel hardware on every enclosure we build to meet the broad range of environmental conditions across the United States. We want our enclosures to look as good in 20 years as they do the day they were installed.”

A few weeks after the generator sets arrived at Hennig, the enclosure and fuel tank packages were ready to ship. There were some logistics challenges on this project, as the facility site was in the midst of construction.  Delivery was made down a temporary dirt road and the three 2 MW Cummins emergency power generators were set in place without a hitch at the new Broken Arrow Water Treatment facility site.

The Broken Arrow municipal water treatment facility is primarily funded by loans totaling $64.8 million, administered by the Oklahoma Department of Environmental Quality and the Oklahoma Water Resources Board. The facility is being constructed by Crossland Heavy Contractors of Columbus, Kansas.  The first phase of the project is scheduled to be operational in July, 2013.
