Tooling inventory is also reduced, which provides additional savings. Hard turning is a highly flexible process that can often be used dry, eliminating both coolant costs and the need for coolant disposal. Cost Savings – In general, CNC turning centers are less expensive and can perform multiple functions versus specialized grinding machines. Hard turning can be successfully used on complex material such as case-hardened steel, steel alloys, and sintered tungsten carbide when used either as a replacement for grinding operations or as a pre-grinding process. With single-point cutting and turning, the process can produce grooves and contours, even high precision threading, in a single chucking. Hard turning typically refers to a lathe or turning center using single-point turning tools to process materials with hardness values over 45 HRc, typically in the 58-68 HRc range. While grinding is still the preferred method for certain workpieces and applications (such as very long and thin items, medical parts, or components requiring tolerances less than ☐.0002 inch), it’s time to take another look at the potential savings and other benefits of hard turning. With the hard turning process, you need just one machine and operator to produce high precision parts at a faster throughput rate, resulting in a lower cost per part.Īs a result, hard turning has become more popular worldwide, replacing many traditional grinding processes. These machines can expertly turn hardened materials using off-the-shelf ceramic and CBN cutting tools, repeatedly achieving accurate results. With a lower cost and the flexibility to provide a broader range of processes, high precision turning centers can be a more economical and useful purchase than a specialized grinder. However, new technologies and designs enable super precise turning centers to produce results comparable to grinding. Before developing high precision hard turning machines, grinding was the preferred method for producing workpieces with very high tolerances.
