For decades Hardinge has been the leader in Hard Turning. Here you will find just some of the experience and information we have on Hard Turning.
Let our team of application engineers work with you to prove that when Hard Turning needs to be done, Hardinge is the right partner to use.
What is Hard Turning?
Hard turning is defined as the process of single point cutting of part pieces that have hardness values over 45 Rc. Typically, however, hard turned part pieces will be found to lie within the range of 58-68 Rc. The hard turning process is similar enough to conventional “soft” turning that the introduction of this process into the normal factory environment can happen with relatively small operational changes when the proper elements have been addressed.
Part Materials applicable to Hard Turning
The typical materials which are routinely used in hard turning include those of the following broad category descriptions:
Steel alloys,
Bearing steels
Hot and cold work tool steels
High speed steels
Die Steels
Case hardened steels
Waspoloy, Stellite and other aerospace alloys
Nitrited irons and hard chrome coatings
Heat treatable powered metallurgy
A sample Hard Turning Part is below:
Material: M2 Tool Steel --1" Bar Hardness: 62 Rockwell C Application: Machine Complete From Pre-Hardened Bar Stock Removal: .1875" per side (total) Tolerance: ± .0002" Surface Finish: 6 RA Machine: Hardinge T42SP with sub-spindle Cycle Time: 5 minutes 50 seconds
