The Processing Property of Deep Hole Skiving Burnisher Machine for Hydraulic Cylinders

Deep Hole Skiving Burnisher Machine for Hydraulic Cylinders is a new type of efficient machine, independently developed by our company reference to the technology of the similar foreign machines. The machine is equipped with large power, strong rigidity, wide margin of machining process and extremely high machining efficiency, is the ideal equipment for all kinds of cylindrical workpieces with deep holes.

This machine can process a variety of mechanical hydraulic oil cylinder, cylindrical workpiece holes and ladder holes, etc. The machine is mainly used for boring and rolling processing, machine tool adopting the precision boring cutter rotating scrape, rolling processing technology. Remove chips in front when boring and scraping and the boring way is to push boring, granted by the oil tank in central of boring bar, remove chips on the head of a bed. The rolling is the post-tensioning, applies the high-speed scraping and boring rolling head, can processing efficiently the oil cylinder, reversing the traditional process of a rough boring, glossy boring, grinding cylinder, the production efficiency is the traditional process of 5 to 10 times.

Application of this machine will have an epoch-making revolution for the oil cylinder production. Cylindricity and alignment of processing workpieces is very high, cutting and rolling speed can reach 1 m/min with the cylinder produced by cold drawn pipe, cutting and rolling speed can reach 0.3 m/min with the cylinder produced by hot rolled pipe. Finish the molding at the first time.

Machine bed is manufactured by high quality cast iron, with strong rigidity and strong stability. Boring bar box spindle is drove by 70KW ac servo motor, boring bar box spindle is drove by servo motor, wide speed range, large output torque, feed system uses 48NM ac servo motor driven double rack transmission, smooth feeding, long service life and can adapt to the needs of all kinds of deep hole machining process, workpiece loading card adopts tight hydraulic cylinder, stable and reliable, easy handling, electrical system adopts centralized control CNC system, can be interactive, graphical display, flexible operation, safeand reliable. In production it is suitable for mass production can also be suitable for small batch production.

Machine tool is equipped with large capacity automatic chip removal machine, drum magnetic separator, collect automatically iron into attle box, cooling fluid can be recycled by precision filtration.

The Accuracy of Machine Machining

Precision of bore diameter: drilling hole IT8 ~ IT9; Boring hole IT7.

Roundness: 0.036mm/Ф200mm (after the fine boring).

Cylindricity: 0.05/500mm (after the fine boring).

Roughness: Heavy boring: Ra6.3um. Fine boring: Ra1.6um. Rolling: Ra0.4um.

After-sales service
