Cutting tools

This section contains cutting tools, inserts, and related products and services.

Boron-carbide coating

Diamond Black is a micro-thin, hard boron-carbide alloy coating that is applied by a low-temperature deposition process. Tools coated with this inorganic material run longer at higher speeds and feeds with no change in coating structure. Coating registers 95 on the Rockwell C scale and up to 5000 Knoop hardness value. This extreme hardness provides high wear resistance, yet tools remain tough and resist chipping and cracking when stressed.

Carolina Coating Technologies Inc, Conover, NC.

Helical oil holes

DSC spiral jet drill is a self-centering, split-point, solid-carbide oil-hole drill with a coating of titanium nitride. Its helical-oil-hole design distinguishes it from other drills and gives it advantages over other highspeed drills.

The drill's helical oil holes follow the helical flute and maintain the same relationship with the cutting point. This means the drill can be reground many times, maintaining its original efficiency.

The drill eliminates chip-packing problems through coolant flow and optimum web thickness. It operates at 10 times the speed and feed rates of conventional high-speed drills.

The drill comes in two lengths and is available in both metric and English sizes. Metric sizes go from 5 mm to 16 mm in 0.1 mm increments. English sizes go from 13/64" to 5/8".

Coolant-fed tools

Coolant-fed right- and left-hand aluminum rougher end mills will be displayed. Three exit holes on each end-mill direct coolant streams to cutting edge to flush chips. Sizes go up to 2" dia by 6" LOC.

Carbide end-mills are solid, brazed-on spiral, and replaceable insert. New front plate, thread-rolling head allows rolling threads to shoulder on parts with flange or angular construction.

Fette Tool Systems Inc, Brookfield, WI.

PVD coating

Alloy coating of titanium aluminum nitride (TiAlN) called SCI-17, will be featured on a selected group of cutting tools. SCI-17 exhibits a higher hardness than TiN. The coatings' resistance to oxidation caused by elevated temperatures produced in the cutting zone is also higher.

Two to five times tool-life factor has been experienced in machining of titanium and nickel alloys using TiAlN versus uncoated or TiN-coated tools. Tests conducted at elevated cutting speeds with ferrous materials, such as 4140, have shown that SCI-17 out-performs TiN-coated tools.

Multi-Arc Scientific Coatings, Rockaway, NJ.

Bore-sizing and finishing

This bore-sizing and finishing press uses the ballizing method to replace slow multistation hones and internal grinders normally used when great precision is required. The machine guides a workpiece with a premachined hole over free

carbide ball to displace and harden surface metal. This action reduces the initial tolerance from [+ or -] 12 microns to [+ or -] 4 microns, well within the sizing range of precision diamond or CBN abrading tool shown in the diagram. The abrading tool floats as it rotates to find the true center.

The combination of tools can reduce bore tolerances to [+ or -] 1 micron. Bore diameters from 1/8" to over 2" can be sized and finished, and the return stroke over the ball leaves work-hardened, plateaued, load-bearing lands interspersed with shallow lubricant traps.

Ty Miles Inc, Westchester, IL.

Metal-cutting tooling

Complete line of tooling for all metal-cutting requirements include standard and special toolholders, milling cutters, rotary tooling, special carbide inserts, coated products, and special form-ground tools.

Fansteel VR/Wesson, Plantsville, CT.

Vitrified-bond CBN wheels

Vitrified-bond CBN grinding wheels are manufactured at low temperatures, which preserves the strength of the CBN abrasive grain. Advanced bond technology assures the maximum bonding strength between grain and bonding material.

Vitrified bonds offer several advantages such as higher coefficient of elasticity for bond rigidity, increased mechanical strength for improved crystal retention, and thermal stability for consistent grinding performance.

Noritake Co Inc, Secaucus, NJ.

Polygon tooling system

Capto modular tooling sytem is designed to work equally well for turning, milling, and drilling applications in almost any machine tool. System offers high levels of torque transmission, bending strength, accuracy, and automation.

Key is the special coupling system. A triangular, tapered, polygon shank ensures torque transmission for rotating tools with even distribution of forces. Lasting alignment of coupling to centerline is possible with the elimination of driving keys or pins.

Coupling is ground on external and internal mating faces to provide good fit and contribute to resistance to bending forces. Radial and axial accuracy of the polygon and flange face offer good repeatability for tool positioning and changing. Coupling can be easily integrated into various holders and clamping units.

System is available in five sizes (32, 40, 50, 63, 80) with adaptors and extensions. Options include tool monitoring, measuring probes, tool identification, and tool management software.

Sandvik Coromant Co, Fairlawn, NJ.

Double-blade cutters

GH-S chamfering tools can be used on hole diameters from 3 mm through 100 mm. Desired chamfer size is determined by tool-adjustment feature and feed of the machine. Double-blade cutting system creates front and back chamfer in a single pass without reversing spindle direction, or programming time-consuming off-center operations. With different set of blades, the tool will accomplish cross-hole deburring.

GH-Z back spotfacer and counterbore tool is capable of producing accurate back spotfacing requirements and precision forms. Parallel actuation of the blades gives stability and prevents chips from interfering with cut. Twin blades are available in high-speed steel and carbide. Diameter adjustment built in the tool allows regrind of the blades.

Snap-change toolholders can be used for machining and can also become part of the tooling. Toolholders repeatedly return to accurate concentric and linear tool locations within seconds.

Ultron Snap-Change, Long Beach, CA.

Clean coolant

Systems remove tramp oil and kill coolant rancidity in a two-step process. First, tramp oil is removed to levels of 0.25 percent or below in a high-speed disk centrifuge. Second, flash pasteurization kills any biological activity to levels of freshly mixed coolant or below. These systems prevent tramp oil buildup and keep biological contaminants at low levels without the use of toxic chemical biocides.
