Here at Peninsula Iron Works we have a reputation for tackling some of the largest part envelope machining projects in the northwest, but that only describes half of our capabilities. Our fabrication division has been doing large and complex work for many years. We have experience with a huge variety of material types and specialty processes that many shops don't. Backed by our in house mechanical engineering team we take on projects with an analytical mindset; front loading what we perceive to be potential pitfalls in order to help avoid costly errors and delays. Our recent acquisition of this 88,000 lb capacity weld positioner is going to allow us even more flexibility and efficiency when planning for large fabrication and repair work.
Your investment is in good hands, we've invested BIG!
In order to perform complete repairs on your crushing equipment we have had to invest BIG. Our equipment is some of the biggest around. Our largest vertical lathe can handle a part 20' (that's feet not inches) in diameter and weighing up to 250,000 Lbs. Which means that a major repair like this 7' crusher mainframe can be accurately positioned, dialed to precise center location and machined to the correct specifications. CNC technology on this and all of our machines, means that we cut straight and complex tapers, convex and concave surfaces and long deep bores and diameters with an accuracy that would be almost impossible any other way.
For every action there is an equal and opposite reaction, the violence that it takes to crush stone and recycled concrete is imparted on the equipment as well. Years of hard service eventually migrates this damage to parts of your machine that need bearing surfaces to make maximum contact. Behind the wear parts that touch the rock, mating mechanical surfaces will wear to a point that a crusher has to be taken out of service or risk even greater damage. We've seen it and we've repaired it. By building up these surfaces with new metal (weld overlay) and then loading these large parts into our machines we can locate back to original center lines and critical features within thousandths of an inch before machining those surfaces back to their original spec's or to 'fit' to mating parts. When it comes time to put it all back together, this accuracy means that parts will have the right amount of contact, bearings will have the correct pre-load and moving parts will be able to do so without binding. This is the quality of a repair that often can't be seen but makes a big difference when it comes to service life.
Experience the difference working with a company that has made the necessary investment to control the rehabilitation process from beginning to end, we do it all here in our facilities where we can control the quality and the schedule and get you back to doing what you do best as soon as possible.
Heavy and complex assembly... No problem!
We don't just fabricate and machine large complex components. We can provide full assembly on even the toughest projects allowing us to be your one stop shop from start to finish on heavy industrial projects.
Bridging the old to the new
Many years of development and thousands of hours of run time on our machine spindle highlighted in this story by Sandvik Coromant. You can call or email us to place your order for your spindle. We can build it to match your requirements for RPM limits and torque. Watch your planer mill or multi spindle run like a modern machine tool. All of the options are available in this platform; manual push-button tool change, automatic tool change via programing and a rack bolted to your floor or table, through spindle coolant, through spindle air, through spindle mist, MQL, spindle orient, automatic gear change, 28,000+ lbs of tool retention force without a retention knob to break. The strongest and stiffest machine tool coupling/interface in existence with 100mm face contact for extreme bending stiffness.
Remember the days when young people would build hot rods? This is a hot rod for your machine shop. You take that old, stiff, heavy, damp chassis (those are all good traits for a machine) and bolt a super fast modern engine to it and have some fun smoking the tires! When you realize you can drill holes using carbide indexable drills with coolant in about 1/4 of the time you used to you will then realize your rapid and milling feed rates seem slow by comparison. Then call us back and have us retrofit your entire machine to ball screws and the latest Fanuc control. How about some Turcite or scraped ways? You could spend millions of dollars to replace that machine with one that has the same capacity or rebuild what you have for a lot less money for a faster ROI and more money in your pocket.
