The TAG90 center-through-coolant angle head and AG35 high-pressure coolant adapters from Big Daishowa are the newest additions to its fixed 90-degree angle head lineup.
These center-through-coolant angle heads deliver coolant directly from the machine spindle to the cutting edge, bypassing the stop block, which enhances cooling efficiency and chip removal. The new angle heads support coolant pressures up to 1,000 PSI.
Customers can choose between the Build-Up type angle head, which allows users to change the adapter for use in various machining applications, or the HMC type angle head—a high-rigidity milling chuck. The Build-Up type angle head leverages AG35 high-pressure coolant adapters, including the New Baby Chuck and Side Lock adapter types.
Big Daishowa’s angle head lineup allows shops to combine vertical and horizontal operations on one machine, and to access hard-to-reach features on a workpiece that would otherwise be impossible without multiple setups. This can reduce cycle times while also improving overall accuracy and eliminating the potential for error created by multiple setups.

- 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.
