Walter WAL-506 Cermet Turning Inserts Boost Stability

Walter’s WAL-506 indexable cermet turning inserts use the company’s FP2 geometry to reduce vibration, produce stronger corners and enhance surface finish.

The WAL-506 indexable cermet turning inserts from Walter specialize in applications requiring a soft cut and high precision. The inserts achieve this balance of performance through FP2 geometry, which is a high positive (18-degree) rake angle geometry with soft hone that reduces cutting forces and vibration tendency. The inserts also extend tool life through WEP10C-coated cermet grade with multilayer TiCN TiAlN PVD coating and fine cermet micro grain. Walter says this combination of edge preparation and grade promotes dimensional stability over long periods of time, boosting productivity in mass production.

Walter’s FP2 geometry uses “minus tolerance” or “maximum corner radius” tolerance to present what the company says is a stronger corner radius than a standard ISO/ANSI corner radius. For example, machining a shoulder with a 0.0157" corner radius usually requires an ANSI-0.5 corner radius (0.0078"). With the FP2 geometry, however, machinists can use a 1M tolerance (equivalent of ANSI 0.0157" but 0.0146"+/-0.0008" tolerance corner radius). In addition to machining the same feature, the FP2’s corner radius also boosts tool life and surface finish. Walter recommends WAL-506 inserts for finishing thin-walled components, components with small diameters, long components and components with unstable clamping, as well as for fine boring applications.




Roemheld PC 80 Holds Prismatic and Round Parts

Roemheld’s PC 80 manual vises are compatible with prismatic and cylindrical components, changing between the two in minutes.

Roemheld’s PC 80 Clamping System is a manual vise that comes in fixed jaw and self-centering styles. It features a rigid, all-steel design, and includes clamping jaws with a dovetail-shaped serrated gripping feature that users can reverse or change out. The vise can hold manufacturers’ round inserts, enabling users to securely clamp cylindrical parts or billets from 44 to 95 mm in diameter. This provides the benefit of no longer needing an additional custom workholding solution or set of soft jaws to hold parts of different diameters. Users can convert the vise back to its conventional role of holding prismatic components within minutes.

The PC 80 has a stroke of up to 62 mm and a clamping force of up to 4500 lbs. The vise is compatible with Roemheld’s own five-axis riser, as well as quick-change solutions like other manufacturers’ zero-point 52-mm pins or a Quintus Pull-Down Bolt.




Dormer Pramet Offers Versatile Stainless Steel Insert Array

Dormer Pramet’s range of stainless steel cutters and inserts optimizes productivity on low-power machines, while also offering versatility for different cutting conditions and applications.

Dormer Pramet says its stainless steel milling range increases productivity for face milling and offers versatility for different cutting conditions. Insert styles in this range include OEHT (octagonal), REHT (round) and XEHT (wiper), while the company’s S450E double positive 45-degree milling cutter enables customers to use the same cutter body with both octagonal inserts for face milling and round inserts for face or copy milling. The milling cutter’s design also supports internal coolant delivery.

The company recommends using this milling range on machines with limited power, saying the combination of the inserts and cutter delivers high metal removal rates at low cutting force and reduces chatter.

This combination features positive axial and radial face angles for good cutting action and directs chips away from the work-piece. The company also says the S450E performs well with fragile work pieces and unstable fixturing, that it is available in a variety of diameters and that it restricts stainless steel work hardening.

Dormer Pramet would like to draw particular attention to the OEHT (octagonal) insert’s use of eight cutting edges, which the company says is the highest number available for positive inserts, and its four sharp, positive geometries for various cutting conditions. These geometries include the MF geometry for finishing applications in stainless steel, mild carbon steel and non-ferrous metals; the MM geometry for machining stainless steel in medium cutting conditions; the M stabilized geometry for difficult cutting conditions in materials such as carbon steels and harder stainless steels; and the FA geometry for finishing and light-to-medium machining of non-ferrous materials. The company also says the new geometries offer reduced cutting forces and increased durability for machining with or without coolant.




ATI QC-7 Robotic Tool Changer Features Wide Interoperability

ATI Industrial Automation’s QC-7 Robotic Tool Changer offers a wide variety of configuration and compatibility options.

ATI Industrial Automation’s QC-7 Robotic Tool Changer offers a variety of configuration options with ATI’s Pass-Through Utility Modules and Tool Stand systems. An optional ML12 Electrical Module can attach to the QC-7 Tool Changer body, which includes five pass-through air ports and lock/unlock air fittings.

The QC-7 Robotic Tool Changer, which ATI Industrial Automation describes as lightweight yet durable, features a low stack height and mounts directly to ISO 9409-1-31.5-4-M5 robot wrists. This tool changer is compatible with ATI’s modular Tool Stands and has an optional tool storage hook to simplify robot programming.

ATI Industrial Automation’s QC-7 also features pneumatic actuation, No-Touch locking technology and a patented Fail-Safe locking mechanism for a secure connection between the master and tool. The design integrates lock/unlock sensors without the need for an additional interface plate. This tool changer handles payloads up to 35 lbs (16 kg), and the company says it is compatible with variety of industrial and collaborative robot models.




Walter Increases Strength and Teeth of Xtra-Tec XT M5130

Walter has revised its Xtra-Tec XT M5130 shoulder milling cutter, increasing its productivity with more teeth, an enhanced clearance angle and a new insert-mounting position.

Walter has revised its Xtra-tec XT M5130 shoulder milling cutter, increasing its productivity with strength-enhancing features, a new mounting position for inserts, a 7-degree clearance angle and 17% more teeth.

The M5130 handles a wide array of machining operations including face, shoulder, ramping and pocket milling, as well as circular interpolation operations. Walter recommends it for machining steel, stainless steel, cast iron, non-ferrous material and materials with difficult cutting properties.

This wide range of applications results in lower tooling and administrative costs, and its 90-degree approach angle reduces the need for finishing operations.

Walter’s M5130 features two pitches for different applications, and a stable cross-section due to the modified installation position for indexable inserts. The cutter is available in diameters between 0.5 and 6.0 in. (10-160 mm), and four geometries: F55, for increased stability; G55, for medium machining conditions; K55, for light cutting; and M85, for aluminum machining, low cutting forces and sharp cutting edges.
