The new Walter G4014-P grooving tool holder is ideal for small part machining operations such as swiss type machining. The system offers an innovative new “SmartLock” insert clamping feature to access the clamping screw from the side.
This makes it possible to change inserts in the machine – even where space is limited—in particular on long center lathes and multi-spindle machines. As a result, changing inserts is approximately 70% faster. The clamping forces are around 30% higher than those of existing tools in the market, increasing the stability and enabling users to achieve a significantly longer tool life. The clamping screw can be accessed from either left or right side; thus, the operation of the tool from either side is possible, making it a very flexible system.
The patent-pending positive engagement design of the insert seat also contributes to the flexibility. The cutting insert is seated in the insert pocket with an innovative prismatic design. This prevents incorrect engagement, especially for narrow insert widths, and enables an extremely high level of indexing accuracy. The Walter grooving system consisting of G4014-P and DX18 inserts is available in the shank sizes of ½- 5/8 in. and 10–20 mm, with insert widths from 0.059-0.118 in. (1.5–3 mm) and for parting off diameters of up to 1.38 in. (35 mm).
The holder designs are offered with either precision cooling on the rake and flank faces or without internal cooling. These special features make the system the current benchmark in terms of the mass production of small parts like shafts, plug contacts, nozzles or implants. Typical applications include automotive suppliers, medical engineering as well as the electronics, food processing, watchmaking and general engineering industries.
Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.
When used in lathe or screw-machine operations, this process separates a completed part from chuck-held or collet-fed stock by means of a very narrow, flat-end cutting, or parting, tool.
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.
Walter has unveiled the Walter Cut G1221-P, an innovative grooving boring bar with precision cooling, for recessing and internal grooving. This monoblock boring bar has two coolant holes.
Walter has introduced three new Walter Cut GX Tiger·tec Silver CVD grooving and parting grades—the WKP13S, WKP23S and WKP33S—for use on steel and cast-iron applications. These have been introduced in combination with Walter's geometries UD4, UA4, UF4, RD4 along with plunge grooving and parting…
Walter has introduced the M2136, a multitooth close-pitch finishing cutter that features a high degree of process reliability coupled with superior cost effectiveness, particularly with cast iron, thanks in part to its eight cutting edges per insert. These stable, negative inserts promote not only…
Walter says its new FM5 finishing and RM5 roughing indexable insert geometries deliver optimal cooling, longer tool life, and increased productivity in high-temperature alloy and stainless-steel machining. The new inserts owe their effectiveness, in part, to their "jet guiding geometry,"…
Walter has expanded the capabilities of its popular Walter BLAXX M3024 heptagon milling cutter with new wiper inserts. The inserts, which have two right-hand and two left-hand cutting edges, were specifically developed for the Walter BLAXX M3024, and allow it to be used for finishing operations.
Walter has added to its range of solid-carbide milling cutters with the introduction of its MC232 Perform product line. This versatile, cost-effective new cutter type is available with 2, 3 or 4 flutes, in a diameter range of 1/8 in. to 5/8 in. (2 to 20 mm).
Walter says it has introduced a new and innovative cutting geometry, the MS3, teamed with a new high tech grade, WSM01. The new WSM01 grade, manufactured using the HiPIMS (high-power impulse magnetron sputtering) method, provides extremely smooth surfaces that are characterized by excellent layer…
Walter has expanded the productive and cost effective Walter Titex Perform lineup of TC115/TC216 taps with an array of new sizes. The Perform lineup of products is one of three categories to Walter Titex threading tools. Perform tools are products that provide an economical solution with focused…
Walter has introduced the Walter Cut—Modular System G2612/2622, new SX system tools for deep grooving and parting operations that reportedly save time and cost. Suitable for all machine types, and for grooving and parting-off ranging from small to large diameters, the system allows users to simply…
Walter has introduced two new products for the DC150 drill lineup: 3xD and12xD, both with coolant through the tool body. The DC150 is positioned in the Perform line—a tough, versatile and cost effective Walter Titex family of solid-carbide drills. The two, new length-to-diameter ratio drills join…
