Host Machine Inc.

Last year was a pretty slow year for us as a lot of our customers were either shut down or running at limited production. As the plants are going back to full production we are getting a rising mount of repairs. This is a 6" Dia. 4340 maindrive shaft for a large bandsaw. It was sheared completely off at the shoulder ,shutting down the plate side of their plant. I had to source a new pce. of 4340 , and remachine the shaft, press on all the new bearings and drive hub and get it back to the customer. Turn around time start to finish 16 hrs.

More machining on the crankshaft

Couple of short videos I took while making the crankshaft

Spent last Saturday machining a replacement crankshaft for a customers laminating machine. The first pic shows the damaged part and the pce I made the new one from. This is typical for our shop, There are no blueprints for the part , so we have to reverse engineer from the damaged sample.

Just finished up an 8 5/8 Casing Spear for one of our good customers on the East Coast.

A good customer came to me with this heat treated bearig shaft . Said he was told you couldn't cut a keyway in a heat treated bearing shaft. Used a Accupro 4 flute solid carbide AlTin coated endmill and proceeded to cut a 48" long keyway the full length of the shaft .

Had to use our big horizontal press to remove this 120 mm x 12foot long extruder screw that had gotten galled and seized in the barrel. Took a little over 200 tons to get it to move. Zoom in on the first pic and you can see on the screw where it had seized in the barrel.

Here are a couple of pics, from my customers job site , showing the spreader bar we built over the weekend being used to install the casing

Setting up and line boring a large backstop for a shear. It had a pin come out on one side and badly damaged the bore . We set it up , welded and rebored to the hole to get it repaired for a fraction of the cost of having to replace the backstop.

Cody and I building a 20' spreader bar for a customer. Had to have it done over the weekend and ready for pickup at 6:am Monday. Good Day at work. This is the kind of service Host Machine can provide . We do our best to help customers minimize their downtime.

Here is an obsolete gearbox from the 60's that a customer brought to us to repair. It is essential to his company and cannot be readily replaced. He brought it to us with a broken/sheared input shaft , but upon disassembly we discovered a lot more damage. The bearings in this gearbox are no longer available and we had to source new ones and modify the gearbox housing to accept the new bearings.... The last few pictures show the reassembly and the finished gearbox. It was installed this weekend and the plant is back in service.
