"As the biggest cnc lathe hard turning manufacturer,we have the most advanced technology, the most professional technical team.So we bileve we will sport the mosr professional and the best Services.
Stiffness determines the cnc hard turning lathes machine precision. Manufacture of machine tools for nearly 15 to 20 years, almost every good rigidity, enough to withstand hard turning lathes. In many cases, the overall condition of the machine is more important than the life of a great extent, Well-maintained engine lathe can also be used for cnc hard turning lathes.
In order to increase the hard turning machine stiffness and damping characteristics, Shenyang Hermos CNC Machine Tool Co.,Ltd. take the many advanced features for a machine turning centers. These include polymer composites reinforced base ,collet chuck (so close to the workpiece spindle support) directly with the spindle and hydrostatic guideway. System meant to maximize rigidity to minimize vacant, tool extends and protruding parts, and cancel transfer gap tablets and washers, the goal is to keep as close as possible to all components turret.
Although cubic boron nitride (CBN) inserts are expensive, but suited for cnc hard turning lathes. CBN inserts can be maintained in the same location during the intermittent cutting, provide security in a continuous cutting process tool wear rate. When using reasonable hard turning process, in addition to compare CBN grinding blade diameter tolerance in control, the other properties are second to none.
Not as good as wear-resistant ceramic CBN, it is generally not used in machining tolerances of less than ± 0.025mm. Ceramics are not suitable for interrupted cutting, And it can’t add coolant, because thermal shock can cause the blade to break. Blunt edge of the blade geometry is the inherent characteristics of ceramic materials, this feature makes the cutting force increases surface finish decline. In addition, the ceramic blade edge can be catastrophic rupture, it could cause all of the cutting edge can not be used. Cermet (cubic titanium carbide) for continuous cutting case hardened material is very effective, although it does not have the wear resistance as CBN, However, in most cases, the blade will be in proportion to the wear without breaking.
Positive rake angle blade cutting force due to its small, it is not usually used in high-rigid hard turning machine. The most reasonable application on the blade, it is recommended close cooperation with tool suppliers, especially in the initial stages, in order to rapidly achieve the best cutting speed."
