Z & L Machining, Inc.

A client from the agricultural industry approached Z&L Machining, Inc. to produce a flame cut and machined steel flange. We began the process by flame cutting the rough size of the 160mm X 12mm Exten 50 steel flange. Then, using the latest Mazak CNC lathe and Okuma CNC mill, Z&L faced both sides of the flange and then drilled and deburred 9 holes into the entire order of 360 steel flanges. We finished product with yellow dichromate zinc plating that had a .00032" minimum thickness. As always, we met our clients exacting standards and all of our work was done within tightest tolerances of +0.190mm-0.075mm.

Z&L Machining Inc. was approached by a Tennessee-based company to custom manufacture hardened steel pins specifically designed for a heavy construction equipment application. To fill this order, we used a detailed and exacting five step process that took advantage of our state-of-the-art equipment including a Kasto saw, Hey centering machine, Mazak CNC lathe and mill and a Cincinnati twin grip centerless grinder. Each of the 57.3 kg pins was made using hot rolled 4140 heat-treated steel within tightest tolerances of +0"-.0014". o guarantee the highest quality product, we went through extensive testing and inspection process that included the use of a micrometer, calipers, gage pins, hardness tester and profilometer. To learn more about how we manufactured these hardened steel pins see the details below. For information about any of our other outstanding services and products please contact Z&L Machining Inc.

A Tennessee-based construction equipment company approached Z&L Machining, Inc. to manufacture welded brackets. These brackets of laser cut and hot rolled 1018 steel bar stock were to be used within a weldment for heavy construction equipment. The brackets were saw cut to a length of 4.331" ±.020" using a Kasto saw. They were then drill, tapped, and deburred with an Okuma CNC Mill. Finally, the seats were welded to the HR A-36 plate with a Miller MIG welder. Each 2.73 lbs. bracket was then tested and inspected using calipers, thread gages and a CMM. Using these top of the line machines, processes and testing, Z&L was able to create a run of 1, 400 brackets within tightest tolerances of +.005 -.003". For more information about these welded brackets or any of Z&L Machining Inc.'s other projects please contact us or see the details listed below.

A heavy construction equipment company from Georgia came to Z&L Machining, Inc. to fabricate a steel boss weldment. To fill this order, Z & L started with hot rolled 1026 steel tubing and steel forging. The tubing was cut to a length of 10.750" ±.020" using a Kasto saw. Then we utilized our high quality Mazak CNC lathe to face, bore and chamfer both ends of the tube. Finally, we welded the bosses to the tube using a Miller MIG welder. Each of the 98 lbs. steel weldments was tested with a caliper and is within tightest tolerances of +- .008" OAL. If you need more information about these unique, steel weldments see the project highlights below. If you want to create your own custom weldment please contact Z & L Machining, Inc. today.
