China No.1internal roller burnishing tools for hydraulic cylinders

   We can provide CNC Skiving & Roller Burnishing Machines with different configurations that can process work pieces with inner diameters from Ø40 to Ø250 and the lengths of 1.5m, 2m, 3m, 4m, 6m, 9m, and 10m, among others. 

Field of Application

Contruction machinery, colliery hydraulic holder, colliery scaper conveyor, special usage truck, maritime ship, harbour machinery, petroleum machinery, mining machinery, water conservancy machinery etc.

Advantages compared with traditional honing

 1)       Improve processing efficiency: Processing speed is nearly 20 times that of honing.

2)       Enhance surface hardness: Surface hardness is increased by more than 50%.

3)       Processing precision: Processing precision can reach level IT8, and surface roughness can reach Ra0.05-0.4μm.

4)       Working environment: Low noise, non-pollution, labor cost-saving.

5)       Reasonable processing arrangement: Skiving & roller burnishing can be arranged as the last operation after the others (such as drilling oil filler hole, welding, threading). 

Details of the product 

Clamping base: clamp male cone of the work piece by moving the hydraulic cylinder against the locating base, to have the work piece fixed. 

Headstock: Ensure large torque at low speed and constant power output at high speed by adopting ZF gear two-speed transmission box made in Germany. Imported precision bearing is adopted for the main shaft, to ensure its stiffness and precision. 

    Locating base: a new locating base locking device is    adopted to fix the locating base at the desired place.

Boring bar support base: With a new internal structure, it can eliminate vibration effectively when the boring bar is revolving, and ensure the minimization of cutter deviation. 

Cooling system: the bed cavity is used as the fuel tank body, thus saving the floor area required, and providing cooling oil with different pressures and flow rates for processing work pieces with different diameters. The filtering precision can be ensured through ten-stage filtration and high-precision filtration by suction filter.  

Work piece supports: there are two work piece supports. With a V structure, each of them can be adjusted freely according to outer diameter center of the work piece. For they are installed on the guide rail slide, it is convenient and easy to push them.

Electrical Cabinet: the main electrical components are French Schneider.

CNC system: FAGOR from Spain, SIEMENS from Germany and other numerical control systems are adopted.

Cutters: SRB scraping rollfinishing cutters can scrape when moving forward and roll finish when moving backward, in order to prevent blades scraping parts during roll finish, blades are pneumatically controlled for retraction.
