Kennametal has released the Fix8 heavy-duty turning system, which the company says delivers maximum metal removal rates in steel, stainless steel and cast iron. With eight cutting edges per insert, the Fix8 turning system is said to increase productivity of heavy-duty turning operations while providing the lowest cost per edge and reducing cutting forces up to 15%.

“Fix8 is designed to cover a wide range of applications, including turning and facing, smooth surfaces, interrupted and heavily interrupted cuts. From medium depth-of-cut to roughing in steels, cast iron and challenging materials like stainless steel, Fix8 Surface Milling Inserts handles it all. Even extreme feed rates of up to 1.4 mm (0.055") and depths of cut up to 12 mm (0.472") are possible with Fix8,” says Matthew Fuerst, product manager, Kennametal.

The design of the Fix8 insert features a rigid clamping system that pulls the insert securely into the pocket seat, reportedly offering superior stability that enables the insert to withstand large cutting forces and vibrations. The insert is also supported by a replaceable carbide shim, protecting the pocket against deformation and damage.

The Fix8 tool holder features precision 3D coolant technology, supplying sufficient coolant where needed. Three coolant nozzles are directed to the rake face, controlling temperature, chip evacuation and supporting chip formation. Coolant exit holes in two different locations are directed toward the flank of the insert, controlling the heat in the cutting zone andprolonging tool life.

Fix8 provides excellent chip APMT Insert control for any heavy-duty turning application while increasing tool life. The insert design reduces cutting forces and power consumption, which the company says makes it ideal for low horsepower lathes.

Shaft parts are a common type of part, which is a rotating body with a length that is generally larger than the diameter. It is widely used in various mechanical equipment to support transmission components, transmit torque and withstand loads. The processing of shaft parts should follow certain rules. You can find out the specific processing steps and some problems that need attention in this paper.
1.the basic processing route of shaft parts
The main machining surface of the shaft parts is the outer surface and the common special surface, so the most suitable processing method should be selected for various accuracy grades and surface roughness requirements. The basic processing route can be summarized into four.
The first is from the rough car to the semi-finished car, to the finishing car processing route, which is also the most important process route for the general external material shaft parts needle outer ring processing, followed by the rough car to the semi-finished car, Then to rough grinding, and finally using the fine grinding processing route, for ferrous materials and parts with high precision, surface roughness requirements and hardened parts, this processing route is the best choice because grinding is The most ideal follow-up process; the third route is from roughing to semi-finishing, to finishing, diamond, this processing route is specially used to process non-ferrous materials, because non-ferrous metals are less hard and easy to block The gap between sand grains is usually not easy to obtain the required surface roughness by grinding. The finishing and diamond car processes must be used. The last processing route is from roughing to semi-finishing, to coarse grinding and fine grinding. Finally, the finishing process is carried out. This kind of route is a processing route that is often used for hardening of ferrous materials and requiring high precision and low surface roughness.
2.the pre-processing of shaft parts
Before the turning of the outer part of the shaft part, some preparatory process is required. This is the pre-processing of the shaft part. The most important preparation process is straightening. Because the workpiece blank is often bent during deformation during manufacturing, transportation, and storage. In order to ensure reliable clamping and uniform distribution of machining allowance, in a cold state, straightening is performed by various presses or straightening machines.
3.the positioning standard of the machining of shaft parts
The first is the center hole of the workpiece as the positioning reference for the machining. In the machining of shaft parts, the coaxiality of each outer surface, the taper hole and the thread surface, and the perpendicularity of the end surface to the rotation axis are important manifestations of positional accuracy. These surfaces are generally designed with the centerline of the shaft as the reference and are positioned with the center hole to conform to the principle of reference coincidence. The center hole is not only the positioning reference for turning and?machining but also the positioning reference and inspection standard for other machining processes, which conforms to the principle of standardization. When positioning with two center holes, it is possible to process a plurality of outer circles and end faces in a single clamping. the outer circle and the center hole as the positioning reference for the machining.
?This method effectively overcomes the shortcomings of poor positioning rigidity of the center hole, especially when machining a heavy workpiece, the center hole positioning may cause the clamping to be unstable, and the cutting amount may not be too large. You don’t have to worry about this problem by using the outer circle and the center hole as the positioning deep hole drilling inserts reference. In roughing, the method of using the outer surface of the shaft and a center hole as the positioning reference can withstand large cutting moments during machining, which is the most common positioning method for shaft parts.

4.to use two outer circular surfaces as the positioning reference for processing.

?When machining the inner bore of the hollow shaft, the center hole cannot be used as the positioning reference, so the two outer circular surfaces of the shaft should be used as the positioning reference. When machining the machine tool spindle, the two support journals are often used as the positioning reference, which can effectively ensure the concentricity of the taper hole relative to the supporting journal, and eliminate the error surface milling cutters caused by the misalignment of the reference.
Finally, a cone plug with a central hole is used as a positioning reference for machining.
?This method is most commonly used in the machining of the outer surface of hollow shafts.
5.the clamping of the shaft parts
The processing of the cone plug and taper sleeve mandrel must have high machining precision. The center hole is not only the positioning reference made by itself but also the benchmark for the outer circle finishing of a hollow shaft. It must ensure the taper on the cone or cone sleeve. It has a high degree of concentricity with the center hole. Therefore, when selecting the clamping method, it should be noted that the number of installations of the cone plug should be minimized, thereby reducing the repeated installation error of the parts. In actual production, after the cone plug is installed, it is generally not removed or replaced in the middle of processing until the processing is completed.

SMW Autoblok says its connectable ZeroAct workpiece positioning system is ideal for manual and electric zero-point clamping in a variety of machining applications including milling, inspection and finishing operations.

With an ultralow profile of 40 mm and a flat design, the company says RCGT Insert ZeroAct works especially well for zero-point applications where z-axis travel of the spindle is critical. The ZeroAct features rapid open and closing of the modules and simultaneous actuation with one twist of the wrist generating 15 kN clamp force. A low stack-up of 38.1 mm increases z-axis travel and better allows for actuation of workpieces onto tables and adapters.

The modular ZeroAct system, with its compact size of 150 x 150 mm, offers the ability to attach up to three clamping modules in a row with a connecting pin that is available in sizes from 5 mm to 105 mm. By actuating the first unit, all three units clamp simultaneously, adding flexibility to machine operations, saving time and increasing operator safety.

ZeroAct is also available in an electric e-motion version to fully automate the manufacturing processes. This version uses a 24V power supply that operates with a built-in electro-motor. Pull down pins are fully interchangeable with the manually operated Carbide Milling Inserts ZeroAct and other APS/WPS zero-point systems.

All modules feature corrosion protection and have a built-in air cleaning function to ensure the clamping system's support surface remains clean and free of chips during changeover or automation. This reduces maintenance and production time, while providing a repeat accuracy of <0.005 mm.

ZeroPoint is part of SMW’s lineup of stationary workholding systems that include manual and pneumatic WPS/APS clamping modules, fully customized and self-centering vises that integrate with automation and pallet systems, and SinterGrip clamping inserts for ultra-low clamping depth and no pre-marking of parts.

SMW Autoblok introduces the fully automated, compact PTP/PTH series twin vises, which provide pneumatic and hydraulic clamping force with standard jaw stroke, long stroke or fixed jaw stroke control.

SMW Autoblok says the vises are ideal for automation; the self-centering PTP pneumatic and PTH hydraulic twin vises work with tombstone and storage solutions, as well as four- and five-axis multi-pallet machining centers — with or without robot loading.

The PTP/PTH twin vises reportedly feature a compact design, high failsafe clamping force up to 60 kN and case-hardened components for high precision and long life. Effective for both O.D. and I.D clamping, the spring-loaded twin vises can be used with industry standard or engineered DNMG Insert top jaws.

In addition, optional SinterGrip clamping inserts are available, which provide no dovetailing and 3.5 mm clamping depth (versus 30 mm standard). SMW Autoblok claims that adding SinterGrip reduces the waste of expensive raw materials and minimizes deformation. A series of solid carbide serrated inserts reportedly grip the workpiece so securely that vibration is virtually non-existent. This stability allows for higher cutting speed and feed rates, translating to more metal removed in less machining time.

All modules are sealed and protected against corrosion and feature a built-in air cleaning function to ensure that the clamping system's support surface remain clean and free of chips during changeover or automation. According to SMW Autoblok, this feature greatly reduces maintenance and production time and Carbide Inserts provides a repeat accuracy of up to 0.01 mm. Sizes include 100, 120, 160 and 200 mm.
