TG2115x6000mm Deep Hole Skiving Roller and Burnishing Machine

Our TG2115x6000mm Deep Hole Skiving Rollers and Burnishing Machines are applicative for machining cylindrical deep-hole work-parts, cylindrical through-holes, different types of mechanical hydraulic oil cylinders, blind-holes and stepped openings. These machines are primarily utilized for roll and bore machining. These follow the boring method of stable work-piece and rotating boring implement. Front-row scraping is espoused for boring. The boring mode is push boring with oil intake by oil feeder and supports chip removal. Rolling is the post-tensioning tossing. An advanced-speed rolling/scraping head is applied that is able for machining oil cylinders, efficiently. The conventional technology of boring and honing machining oil cylinder is varied, with 8 to 10 times of the production efficiency of conventional technology. In every 8 minutes, one∮80 oil cylinder can be produced with a length of 6000mm.

The bases of these deep hole skiving roller and burnishing machines are manufactured from advanced quality cast iron, with rigidity and stability. Boring bar box spindles are driven by ac servo motors, wide speed scope, large yield torque and feed system. AC servo motors driven by double rack transmittance have smooth feeding, extended service life and can adapt to the requirements of all types of deep hole machining procedures. Workpiece loading cards follow constricting hydraulic cylinders, which are firm and reliable with an easy treatment. The electrical system of the machines adopt centered control CNC system, which can be synergistic and have graphical displays with flexible actions. These safe and reliable products are appropriate for mass production as well as small batch production.
