Jan 16, 2006 · It's the steel that is the limiting factor. Keep the tool as close to the boring head as possible. I would use a carbide insert with at most a .010 rad and a fine feed on the bar. If a 63 is not produced, try stoning the rad smaller and increasing the rpm.

Drilling hard steel means lowering speeds & feeds and using the right geometry. Typically, large holes are created using indexable drills. Proper production planning usually dictates that large diameter holes should be completed before the material is hardened. Because this isn't always possible, using the proper tools and machining practices Grade A36 Steel McMaster-CarrChoose from our selection of grade A36 steel products in a wide range of sizes. Includes material certificates and CAD models. In stock and ready to ship.
Nov 14, 2017 · A36 is a low carbon steel. Low carbon steels are classified by having less than 0.3% carbon by weight. This allows A36 steel to be easily machined, welded, and formed, making it extremely useful as a general-purpose steel. The low carbon also prevents heat treatment from having much of an effect on A36 steel. A36 steel usually has small amounts Indexable Boring Bar Feed and Speed Chart Scientific Material HB/Rc Speed Range (SFM) Cutting Conditions; Uncoated ALTiN+ Max DOC ACD & ATD Max DOC ATP Feed IPR; Cast Iron:160 HB:75-200:200-550:0.020:0.060.0005-.010

We specialize in custom metal-slitting, coil tips for turning ASTM A36 ? - The Home Shop Machinist A36 Mild Steel ASTM A36 steel is the most commonly available of the hot-rolled steels. It is generally available in round rod, square bar, rectangle bar, as well as steel shapes such as I-Beams, H-beams, angles, and channels. The hot roll process means that the surface on this steel will be somewhat rough.
SFM and Feed For AD between 0.25 to 0.5 of Tool Dia. SFM = 0.8 Lowest Range Value. Feed at Suggested Value. For AD equal and above Tool Dia. SFM = 0.8 X Highest Speed Range. Feed should be 0.5 X Suggested Value.
