spindle rotation, which in turn calls for a very high rigidity Further modifications are necessary, such as a variable speed for the gradual increase in speed, and a variable feed to minimize the shock while the tool enters and leaves the work piece An example is the VDF German lathe, which has a maximum spindle rotation of 6000 rpm, brought about by a PIV drive This lathe has been installed in the Machine Tool Laboratory of the Indian Institute of Technology, Madras

Hot-pressed ceramics or black ceramics, which were introduced in the 1960s typically, contain a mixture of aluminium oxide and titanium carbide Black ceramics are usually employed in the machining of cast iron with hardness above 235 HB and steel with a hardness of between HRC 34 and HRC 66 Such cutting materials have proved to be quite successful in the machining of hightemperature, nickel-based alloys at speeds up to six times that possible with carbide tools [20] Engineers at Kennametal report that black ceramics are tougher and more fracture resistant than pure aluminium oxide ceramics Because the material exhibits a higher transverse, rupture strength and a greater shock resistance, it is recommended for milling and rough turning applications Interrupted cuts in steel with a hardness of more than HRC 34 have been handled successfully with hot-pressed ceramics Ceramics, which combine aluminium oxide and titanium carbide, in addition to being referred to as hot-pressed and black ceramics, are known by many names cermets, composite ceramics, and modified ceramics Hot-pressed ceramics have found many applications in the replacement of conventional carbides At Westinghouse Electric Corp s Steam Turbine Div (Lester, PA), for example, hot-pressed ceramic inserts have replaced carbide tooling to affect a productivity increase and an improvement in surface finish, eliminating the need for a subsequent polishing operation Some hot-pressed ceramic cutting tools use zirconium oxide instead of tungsten carbide because zirconia is said to make the aluminium oxide base much tougher One such insert is CerMax Grade 460, a relatively new ceramic cutting tool, manufactured by Carboloy Systems Dept, General Electric Co (Detroit, MI) CerMax Grade 460 inserts are now being used by the Aircraft Engine Business Group of the General Electric Co (Wilmington, NC) The company is using the ceramic inserts to machine a variety of engine parts made of Inconel 718 Often, many of the company s parts must be production machined in the fully heat-treated condition, some as hard as HRC 48 Traditionally, cemented carbide was used for cutting operations on Inconel 718 The surface speed was limited to only 80 sfm (24 m/min) for roughing and l00 sfm (30 m/min) for finishing The feed rate was typically 0007 ipr (018 mm/rev) to obtain a surface finish of no greater than 63 in (2 m) At such a relatively low feed rate, the Inconel 718 produced stringy chips The tool life under such conditions usually was no longer than 15 min; many cutting operations had to be stopped midcycle to change tools

Conventional hot-pressed ceramics have been attempted with some success cutting speed could be increased to about 450 sfm (137 m/min) However, notching, chipping, and fracturing proved to be troublesome, limiting the application of such ceramics When Grade 460 was run, the results were significantly better Cutting speeds were increased to 800 sfm (244 m/min), nearly double the speed of conventional hot-pressed ceramics leading to a sevenfold improvement over cemented carbide [21]

The whisker-like grain structures of SiN3 (Figure 216) [22] when added to Al2O3 give the tool toughness, excellent hot hardness and thermal shock resistance Some experts say that silicon nitride will take over where alumina-based ceramic tools have failed a quantum jump in performance Simply stated, tests have shown that silicon nitride materials handle applications such as high-speed roughing even milling of cast iron and nickel-based alloys at higher cutting speeds and chip load conditions than either hot-pressed ceramics or ceramic-coated carbides Some experts say that silicon nitride ceramics exhibit characteristics that combine the high-speed capability of traditional hotpressed ceramics with the impact resistance and high feed capability associated with carbides Silicon nitride tools are also effective when coated with aluminium oxide In one application, a grey cast iron automotive brake disc (180 HB) is rough faced In the past, simple aluminium oxide ceramics were used at cutting speeds of 1200 2000 sfm (366 610 m/min) The tool life was about 150 pieces per cutting edge, but tool breakage was a problem By switching to Grade SP4 aluminium-oxide-coated silicon nitride, supplied by NTK Cutting Tools, it was possible to increase the feed rate to 0020 ipr (0051 mm/rev) and still provide an average tool life of 400 pieces per cutting edge [21] The SiAlONs were developed as a more Fig 216: The microstructure of a silicon nitride economic alternative to hot-pressed silicon nitride ceramic [22] SiAlONs have a complex chemistry and are thought to be a family of alloys with a wide range of properties They are formed when silicon nitride (Si3N4), aluminium oxide (Al2O3) and aluminium nitride (AlN) are reacted together The hot hardness, fracture toughness and thermal shock resistance of fully dense SiAlON make it well suited for use in cutting tools The material is an attractive low cost alternative to hot-pressed silicon nitride for machining grey cast iron for automotive applications The material gives both an increased metal removal rate and a longer tool life compared with conventional cutting tools Tools using SiAlONs have also replaced cemented carbide tools for machining nickel-based super alloys These alloys are used for their heat resistance or in aerospace
