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.

Hardenabilityof steel depends on

The biggest determining factor of a part’s hardenability is its composition. Other factors, like the quenching process, will also impact the depth to which part is hardened.

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.

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.

Process of both external (e.g., thread milling) and internal (e.g., tapping, thread milling) cutting, turning and rolling of threads into particular material. Standardized specifications are available to determine the desired results of the threading process. Numerous thread-series designations are written for specific applications. Threading often is performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut. To perform internal threading, the exact diameter to bore the hole is critical before threading. The threads are distinguished from one another by the amount of tolerance and/or allowance that is specified. See turning.

Hardness is a material property that signifies an alloy’s resistance to penetration. Hardness is dependent mostly on a ferrous material’s carbon content, and a few other determining factors.

Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.

“The Harvey Tool and Helical Solutions Brands serve some of the most advanced and demanding end users in the industry,” said Jerry Gleisner, Senior Vice President of Sales for Harvey Performance Company. “Micro 100’s product line, particularly their strong focus in turning tooling, will allow us to offer additional capabilities and value to our distributors and end users.”

All heat-treated alloys must contain carbon. A steel grade’s carbon content and it’s other alloying elements, help to determine the hardenability of the material.

Hardenability signifies how deep the alloy can be hardened upon quenching after its exposure to heat treatment. The higher a part’s hardenability, the better it will stand up to heavy wear and other stresses during its intended application.

Hardenabilitydefinition Engineering

Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.

When an iron-based metal or steel is heated, its crystal structure changes from ferrite to austenite before being transformed to martensite through the quenching process. By the addition of alloying agents such as manganese, molybdenum and vanadium it increases the hardenability of steel when it is phased to martensite.

The acquisition of Micro 100 better positions Harvey Performance and its brands to compete and grow. “One thing that is a constant in our business is change, with regular consolidation amongst our competitors, our distributors and our end users,” said Jenkins. “We will continue to look to expand our product portfolio through acquisition. Scale matters, and we believe that – through thoughtful assembly of brands and products – we can enhance the end users’ productivity and increasingly earn their business.”

Hardenabilityvs hardness

Moving forward, the Harvey Performance team will focus on scaling and growing each of the company’s three brands. “We will continue to manufacture Helical Solutions product in our Gorham, Maine facility and Micro 100 product in the Meridian, Idaho location,” said Brian McKahan, Vice President of Operations of the Harvey Performance Company. “We have plans for significant investment and growth across all of our brands.”

Hardenabilitymeaning

The quick and focused nature of induction heat treating can control a part’s hardenability. A material that may through harden in a furnace process can be hardened just at the surface with controlled depth using induction heat treating. Unlike other types of heat treating, induction will harden the surface and leaving much of the internal material relatively ductile and flexible, this is ideal for shafts, spindles and axles.

Hardenabilitytest

Hardening and then tempering undoubtedly give a steel part the best combination of strength and toughness. The depth at which a metal alloy can be hardened, also called hardenability is an aspect often weighed during the part design process.Don’t confuse hardenability versus hardness, as they are not the same. Hardenability is impacted by many factors, including the material’s composition, size, and the quenching process.

Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.

The mass and shape of a part also impact hardenability. The more volume a part has, the more it will affect the cooling rate and the martensite transition process.

Proper and consistent quenching is essential to reach the right level of hardenability and the appropriate phase transition of the heat-treated part. The quenching medium, whether it be water, oil, or others, should be selected based on the alloy’s material characteristics.
