  2. Free machining steel - Wikipedia

    en.wikipedia.org/wiki/Free_machining_steel

    Free machining steel costs 15 to 20% more than standard steel, but this higher cost is offset by increased machining speeds, larger cuts, and longer tool life. [1] The disadvantages of free machining steel are: ductility is decreased; impact resistance is reduced; copper-based brazed joints suffer from embrittlement with bismuth free machining ...

    As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...

  4. Broaching (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Broaching_(metalworking)

    The semi-finishing teeth provide surface finish and the finishing teeth provide the final finishing. The finishing section's RPT (t f) is usually zero so that as the first finishing teeth wear the later ones continue the sizing function. For free-machining steels the RPT ranges from 0.006 to 0.001 in (0.152 to 0.025 mm). For surface broaching ...

    Angle view of the Pioneer SX-1980 stereo receiver. The Pioneer SX-1980 [1] [2] [3] is an AM/FM radio receiver that Pioneer Corporation introduced in 1978, to be matched with the HPM series of speakers. It was rated at 270 watts RMS per channel into 8 ohms, both channels driven.

  7. Machinability - Wikipedia

    en.wikipedia.org/wiki/Machinability

    Machinability is the ease with which a metal can be cut permitting the removal of the material with a satisfactory finish at low cost. [1] Materials with good machinability (free machining materials) require little power to cut, can be cut quickly, easily obtain a good finish, and do not cause significant wear on the tooling.

    Hallicrafters founder William J. Halligan depicted in a 1944 magazine ad. William J. Halligan (1898–1992), founded Hallicrafters Company in Chicago in late 1932. Prior to this, he had been involved in radio parts sales for some years but decided the time was right for a handcrafted amateur radio receiver - the company name being a combination of Halli(gan) and (hand)crafters.
