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.
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.
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.
- total indicator runout ( TIR)
total indicator runout ( TIR)
Combined variations of all dimensions of a workpiece, measured with an indicator, determined by rotating the part 360°.
BIG KAISER, a global leader in premium high-precision tooling systems and solutions for the metalworking industries, expands its jet-through hydraulic chuck line to include the BCV interface and additional inch sizes.
The HDC jet-through type holders are ideal for high-precision 5-axis machining with maximum RPM of 35,000 and clamping range of ¼” to ½” and fit nearly any application in the automotive, aerospace, medical, and die and mold industries.
An exclusive thread features allows for convertible coolant delivery between jet-through coolant and center-through coolant. Jet-through hydraulic chucks are ideal tool holders for finishing applications that would benefit from improved coolant delivery. The coolant flows through the end of the tool holder and is angled to direct coolant to the cutting tool tip, greatly improving surface finish and tool life.
BIG KAISER HDC tool holders are simple to use; only 1 hex key wrench is needed to clamp or loosen the cutting tool, making tool changes fast and easy without special equipment. Every HDC toolholder is guaranteed to .00012” TIR at 5 times diameter.
