Seco Tools has announced a new line of Super Turbo chamfer mills designed to provide high metal removal rates while reducing production costs. The new cutters use the same inserts and hardware as standard Super Turbo square shoulder mills, allowing manufacturers to increase the versatility of their operations without additional spare parts.
The new Super Turbo chamfer mills feature a high positive cutting rake angle and positive helix angle to reduce power consumption, resulting in freer cutting and reduced harmonics. The design increases tool life as compared to standard APxx style cutters, helping to reduce cost per part.
The new chamfer mills use the same strong insert pocket design found in the rest of the Super Turbo family of products. The strong insert screws and thick, robust inserts offer increased reliability for fewer tooling changes.
Super Turbo chamfer mills are available in setting angles of 30, 45, 60 and 75 degrees, with a depth of cut capability of 0.197" to 1.653", for production of the most common open or close to shoulder chamfers. The new tools are available in Seco-Capto and Combimaster back-end options, with standard shell mill mounting styles in either inch or metric arbor holes. All versions include internal coolant channels.
As part of the Super Turbo mill family, the chamfer mills utilize the full range of Super Turbo insert grades, including Duratomic coatings, and geometries. This ensures that the tools apply across a wide range of materials and applications.
Seco Tools' Turbo Mill offering is a comprehensive and versatile square shoulder milling product line that provides solutions for slotting, ramping, contouring, plunging, pocket milling and both circular and helical interpolation. The family offers a choice of 13 carbide grades, 3 PCD-tipped grades and 5 geometries suited for a variety of materials, including steel, stainless steel, cast iron, hardened materials, high-temperature alloys and non-ferrous materials. Super Turbo's unique inserts feature an optimized edge, advanced helix angle, large wiper flat and strong, highly positive rake angle to allow high productivity.
Related Glossary Terms
- alloys
alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- arbor
arbor
Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.
- 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.
- depth of cut
depth of cut
Distance between the bottom of the cut and the uncut surface of the workpiece, measured in a direction at right angles to the machined surface of the workpiece.
- flat ( screw flat)
flat ( screw flat)
Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- helix angle
helix angle
Angle that the tool’s leading edge makes with the plane of its centerline.
- interpolation
interpolation
Process of generating a sufficient number of positioning commands for the servomotors driving the machine tool so the path of the tool closely approximates the ideal path. See CNC, computer numerical control; NC, numerical control.
- 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.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
- rake
rake
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
- slotting
slotting
Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.
- wiper
wiper
Metal-removing edge on the face of a cutter that travels in a plane perpendicular to the axis. It is the edge that sweeps the machined surface. The flat should be as wide as the feed per revolution of the cutter. This allows any given insert to wipe the entire workpiece surface and impart a fine surface finish at a high feed rate.
