    Places to pre-shape grinding wheels

    It's just an angled face with a small .250" shoulder. My machines are angle head (20 or 30 degrees, respectively) but the in stock wheels are all squared off. And I am in Eastern PA (Philadelphia) but unless there's someone I can hand deliver to shipping to New York or Minnesota isn't a ton...

    Places to pre-shape grinding wheels

    I'm hoping it's not ongoing. We recently purchased some used grinders and the ball was dropped on ordering wheels so now I am just trying to get something that's in stock in the grit I need. I have placed orders for properly shaped wheels, they are just 12-20 weeks out depending on who I go with.

    Places to pre-shape grinding wheels

    Anyone know of any places that will take a grinding wheel (20x8x2) and pre-dress an angle on it for me? I have a bunch to do because the only stock wheels I can get are straight and I don't want to waste time doing them on my machine here. Wheels are AlOx Vitrified bond. Thanks.

    2013 +Gf+ Mikron HSM 600U LP

    I'm not knocking the control at all. It's a good control, but most people don't have experience with it and therefore stay away from it. Hermle and Kern are not common machines. How many shops have HAAS/FANUC controlled machines and MasterCAM because they know that will ensure and employee...

    2013 +Gf+ Mikron HSM 600U LP

    People who already use it maybe, but that group is very small. Who (MTB) is using Heidenhain in the US as their main/only control option besides Mikron? I know some offer Heidenhain and Siemens but in US markets Siemens is the main one by a considerable margin.

    Here being the US. And I should have stated not as popular in the used market specifically.

    2013 +Gf+ Mikron HSM 600U LP

    From what I have seen Mikrons are not popular here nor do they hold their value well (which is fine for me). I think the Heidenhain control scares people off. We have been able to buy a few of these machines recently for next to nothing, especially considering the pallet pools built in. I think...

    HSK50 Toolcart

    Does anyone know of any tool storage carts (on wheels) that is made specifically to accept HSK50E tooling? I am not looking to make one or modify anything. Huot does not make anything in that taper and they fit too loosely in Cat40, HSK63, and Capto C6-sized carts. Thanks.

    Fadal 4020 Squealing

    Am I crazy or is the machine "movement" in X (table moving left and right) while this is happening, not Y? I have never seen t slots in the Y direction before so I assume you are looking at this from the front of them machine. Are Fadals built or named differently? Stupid question but does it...

    Okuma lnc8 tooling insert up or insert down?

    You can run either. There are a few things I see thrown around frequently and they have their merits, but there's also a very limited range in which I think either way is "better" . Insert down has the advantage of gravity helping with chip evacuation. When the chips are coming off the material...

    Hi Feed Mill for 40 taper

    What are you guys using for hi feed mills in steel? I am looking for something in the 1.5" range for doing 4140/4130 plate. One particular part is starting from 6" round and I have to remove probably 80 percent of the volume. I would like something I can run to helix down through a part as well.

    WHERE DO YOU HIRE PEOPLE ??

    I think his point is that you may not be getting any hits because you aren't offering anything that's worthwhile for people to apply to.

    Feedrate maybe?

    What constitutes a "sharp edge"?

    I had a .010" radius I believe that terminated .005 over major on the part since I was going to raw stock. The part in question was not critical to anything and we were just using material we had to make a tool. It was not sharp but since they didn't see a chamfer they called it "not broken". I...

    What constitutes a "sharp edge"?

    Good morning. I was having a discussion with a quality guy the other day because I had a part that was turned with a conical feature leading to a straight diameter. The conical feature was 120 degrees included. The print said "break all sharp edges" so he told me I needed to chamfer it. is there...

    Brother Horizontal

    Andy, Any idea of what the max workpiece length is supposed to be? I have a couple parts that are18-20 inches but I only work the ends and don't go any deeper than 3" from either end. As long as the part fits without hitting sheetmetal I would have plenty of reach for the tooling.

    36 tooth hss slitting saw speeds and feeds 1040 steel. Help please

    From a SFM perspective that makes sense but if he is saying it's jamming (stalling?) it may not have the torque at 50RPM to use that cutter. Do HAAS mills have high/low gear/windings? Their website shows an override with M41/M42 but also states it should switch automatically. Maybe verify that...

    ER Collet Chucks for workholding

    I know, but there are a few that offer them. Being ER keeps it so I don't have to purchase any additional collets (not that I don't have 5C, 16C etc.) and it's also a very short protrusion from the mounting surface. I have a low profile 5C manual chuck but even that is 4.5-5" tall.

    ER Collet Chucks for workholding

    Thank you. Jergen's actually has the perfect piece for what I need too. ER40 and already on a 52MM quick change pallet with a low "gage length". (I have a Lang plate on my rotary, I was going to make an adapter plate). For the price I'd prefer to find the generic pieces and build my own however...

    ER Collet Chucks for workholding

    Does anyone know of any standard brands that carry something like these "collet chucks" from Amazon? I would like to find something ER40 that is low prolife flange mount like this to mount to a 4th axis rotary. Bonus points if anyone has a 1" hydraulic holder built the same way. Using a...
