µm Milling Chucks by Showa Tool guarantee tolerances as tight as 1µm at the chuck nose and 2µm at 3xD. ERI-America stocks Showa Toolµm Milling andµm Mold chucks in CV40/50, BT40, HSK63A, HSK100A and BIG Plus. ERI America is the exclusive distributor of Showa Tool, including theµm Milling andµm Mold Chucks in North America. The innovative design generates twice the clamping force of hydraulic chucks with extreme rigidity that produces superior surface finishes and dimensional accuracy.µm Milling Chucks are excellent choices for milling, reaming, thread milling and precision drilling.They are available in 0.750", 1.00", 1.250", and 2.00" capacities. Standard and thru-the-flange coolant chucks are available in popular inch and metric sizes.µm Mold Chucks by Showa Tool provide excellent accuracy, 3µm at the chuck nose and 5µm at 3xD. They feature an extended nose design that allows for deep milling and drilling in hard to reach mold and die block cavities. Theµm Mold Chucks provide rigidity and concentricity equal to a shrink-fit toolholder without the cost of induction equipment. Standard and thru-the-flange coolant styles are available in lengths of 150mm and 200mm with inch and metric sizes from 0.125" (3mm) to 0.500" (12mm).
Related Glossary Terms
- chuck
chuck
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- milling
milling
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- toolholder
toolholder
Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.
