Frequently Asked Questions
What is the best material for a heavy-duty machine frame?
Fabricated and stress-relieved A36 or 1018 carbon steel is the most common and cost-effective choice, offering excellent strength and stability. For applications requiring higher strength or specific properties, alloy steels may be used.
Why is post-weld machining important for fabrications?
Welding introduces stress and can cause material to warp. Stress-relieving the weldment and then machining all critical surfaces and holes in a single setup ensures that all features are flat, parallel, and perpendicular for accurate final assembly.
Can you help us with material selection for wear resistance?
Absolutely. Our engineers can recommend the best combination of base material and post-processing, such as using 4140 pre-hardened steel or applying heat treatment and hard chrome plating to achieve the desired surface hardness and durability.
What is the best finish for corrosion resistance in an industrial environment?
For steel parts, zinc plating or electroless nickel plating offer excellent corrosion protection. For a durable and aesthetic finish on external components, industrial powder coating is a superior choice.
Can you hold the tight tolerances needed for bearing and shaft fits on large parts?
Yes, this is a core competency. We use precision grinding and climate-controlled CMM inspection to hold tight diametrical and positional tolerances required for bearing fits (e.g., H7/g6) on large and heavy components.
Do you manufacture custom gear sets?
We can CNC mill and turn custom gear profiles from a variety of steels and alloys. For high-precision, AGMA-rated ground gears, we work with certified partners to manage the entire process for you.
What is a hydraulic manifold, and why is it complex to machine?
A hydraulic manifold is a block that directs the flow of fluid in a hydraulic system. It requires machining intricate, intersecting internal channels and ports. Precision is critical to prevent leaks and ensure the proper function of hydraulic valves.
How do you handle and machine very large and heavy parts?
Our facility is equipped with overhead cranes for safe lifting, large-capacity CNC machines with extended travels, and robust custom fixturing designed to handle the weight and forces involved in machining large components accurately.
Can you assemble the large components you manufacture?
Yes, we offer heavy assembly services. We can install large bearings, bushings, guide rails, and other hardware to deliver a more complete and tested mechanical sub-assembly.
How do you ensure the quality and accuracy of a part that is several meters long?
We use large-format Coordinate Measuring Machines (CMMs) and laser trackers to accurately measure parts that are too large for standard inspection equipment. Our process controls ensure that dimensional accuracy is maintained throughout the manufacturing cycle.
