Machining HUGE 4 Ton Rock Drill Head with CNC machines

Machining huge 4 Ton rock drill head from forged high strength steel using our huge cnc milling machine and huge cnc lathe for Tri-Mach Oy. If you need something like this made in Finland check out our machine shops websites www.vuohensilt... We do also challenging repair work and manufacture lot of prototype parts.

[@SportsKid006-milbert]

AGREED!

[@davidsymalla]

You are correct, really large projects like this are not on youtube. I would love to see more of the these big projects.

[@soylentgreenb]

This looks like the "pilot bit" for a large DTH hammer (for a company like e.g. Lännen Alituspalvelu if it is for horizontal drilling and for any of a large number of people who do foundations if it is for vertical drilling). It's not necessarily only intend for rock-drilling. Using DTH for advancing a steel-casing or steel-pile in coarse, stony, mixed material is very common. This pilot bit will be drilled into to accept a large number of "hard metal", cemented tungsten carbide bits. In Finland, which has very hard rock like all the baltic shield countries, they will be the hemispherical kind of button bits; very smooth and not very sharp or pointy. This means slower drilling, but they do not wear down and break as fast as the pointier sphere-cone-shaped bits. When drilling horisontally, the drill rod also has a large auger that neatly fits into the steel casing. Air from several large compressors (~20 bar-ish) is let through the drill rod to the hammer. The hammer hits this pilot bit, which hits the rock face or soil. In harder materials like rock, only the button bits hit the face; the much softer hardened steel is keept clean by the used air from the hammer, which is channeled to the face of the hammer, blowing away all the small stone chips or whatever is there. The air then is channeled away from the face, around the hammer and into the auger in the steel casing. The drill rod/auger is slowly rotated to remove spoils like an auger conveyor. The pilot bit is slightly smaller than the casing, so a ring bit is used to ream a hole slightly larger than the casing (this is a wear-part, rather than a many-use-part). The pilot bit has a lot of inertia when it starts moving from being struck by the hammer, and it will hit the ring bit that is usually welded to the steel casing (sometimes there is a bayonett-style coupling). This drives the ring bit and casing forward. The hammer is rotated slightly after each blow so that the button bits hit slightly different places each blow. They are also distributed on the face of the hammer so as to make almost concentric circles evenly spaced, so that no part of the rock face avoids being hit by the button bits. As the button bits hit the surface, they do exceed the compressive stress of the rock locally, causing crushing into powder; but outside the area hit by the button bit, the buttons cause bending stress. Rock is weak against bending (like unreinforced concrete) so some cracks radiate outward. Eventually different networks of cracks from adjacent hits line up and small stone chips come off the rock-face.

And then everyone has some PB&J and makes some necklaces from the rock chips before having a nap.

[@unozunoz3705]

Ex-geotechnical driller here: this is drill bit of down-the-hole hammer, start od central hole must be on specific diameter because there is inserted plastic tube that open blowout valve on hammer body, lower holes are for flushing drill hole, and accorhing to size this looks like head for tower drills for blastholes in quaries (Flies away in cloud of dust from drilling)

[@witgangyounotube287]

well if that thing gets outer rings i'd imagine the hole it makes to be atleast 1.5 -2 m diameter, for that to be a blasthole sounds like blowing up whole mountain at once and i don't mean just a layer of it.

[@dickJohnsonpeter]

Yea I was thinking that too. No way would you drill a hole that large for stuffing explosives in.

[@namibjDerEchte]

@@dickJohnsonpeter Well, no _conventional_ explosives.

[@xridex400]

Looks like its for driving casing, the bit is missing the ring cutter that attaches around the head when the string is rotated clockwise, and left at the bottom of the hole by rotating counter clockwise and pulled out thru casing

Thank you for documenting the process, I have encountered many big forgings, big CNC-machines and big machined components, but I don't think I've ever seen how such a large forging is actually machined.

[@braindeadbzh]

[@idahosagebrush5662]

People can make some amazing machinery that we take for granted. Always fascinating to see... Several years ago my wife and I hauled a huge bit that was almost as wide as our trailer and around 20 ft. long from a foundry in Duluth, Mn. to a mine on a mountain in the middle of New Mexico. It wasn't machined like this though, unless it was done at the mine later on. I think it was for production in the mill because the business end was rounded like it went into a huge bowl and not shaped like a rock bit and the "shaft" was like a screw conveyor. Everything in that mine was huge. I doubt one of the haul trucks would even notice running over a pickup truck. Another time we hauled a steam turbine shaft from a power plant near Henderson, NV to get rebuilt in NC. It was driven by steam produced by a natural gas fueled jet engine similar to an F-16 engine, I was told, and had had one of the turbine blades go through it. It was 30 ft. long and weighed 20,000 to 30,000 lbs. The precision of that thing was amazing and the General electric plant we hauled it to had others that weighed over 100,000 lbs and had to be transported on train flatbeds.

As a machinist myself i find this kind of thing very interesting. in the shop i work at we make hydraulic pumps and 360 degree swivels for fire truck and boat applications for their hoses and water cannons. we never get to machine things of this size so it was great to see something like this. I have a few questions Lauri. 1 how many mm per pass were taken off in mill those large slots on the side? At what rpm was the lathe running to face and drill that center hole? seemed like a good speed for something so large and heavy. for a piece this hard already and with the use of coolant with a carbide insert whats the maximum table speed and depth of a cut you can do with this big mill and still be within safety guidelines for your shop? and last but not least when you secure these large parts on the mill table how do you know enough tie downs and clamps are enough to keep in in place to work on safely? thanks for answering these for me, this stuff is awesome to see!!! I sure hope you do more! Cheers from Pennsylvania USA.

[@Beyondthepress]

I am not totally sure about but usually miling tools that we use can take up to 5mm away with one cut. I am not sure did we take so much with this since the material is so hard. The lathe was running probably around 150m/min for outerdiameter resulting in relatively slow rotation speed since the piece was so large The maximum speed of the carbide drill is probably around 100m/s for this kind of material for calculated for diameter of the drill. There isn't anything too dangerous if going too fast drill bits just wear too fast The tie down to milling machine is just about skill of the mill operator and more is better there :D Usually large pieces are easier to mount than smaller ones.
