TGG200x6m Deep hole skiving roller&burnishing machine is suitable for boring ,skiving and burnishing the precision tubes such as hydraulic cylinders , air cylinders and so on . The processing accuracy can up to IT8~IT10 ,surface roughness after burnishing could reach Ra0.2~Ra0.4μm .
Description
This machine adopt workpiece fixed , cutting tool rotary feeding processing method.
The locating base position the workpieces with different length through servo motor, reduction box and Rack and Pinion . The headstock tighten workpiece under the pushing of hydraulic cylinder . The machines is equipped with SIEMENS CNC system ,boring bar box adopts MK brand 50kw AC servo spindle motor ,rotary speed range 10-1200r/min(two-gears ),speed stepless within eash gear.The spindle bearings are NSK brand with high turning accuracy. The feeding box adopt SIEMENS servo motor , speed stepless , the feeding adopt high precision Rack and Pinion structure, to realize the high accuracy and stable feeding of spindle box . The machine bed adopt double rectangular guide rail , to ensure the whole rigidity of machine , with high movement precision and good abrasion resistance. It adopt the Taiwan hydraulic components , performance is stable and reliable . Machine has auto chips removal device ,leak-proof performance is good; The coolant liquid adopt three stages filter, the filtering accuracy is 50μ.
This machine adopts skiving-burnishing processing method , because the workpiece is fixed , it needs to use the floating type skiving-burnishing tool or push boring-pull burnishing tool , the workpieces are cold draw tubes or tubes with rough boring .
TGG200x6m Deep hole skiving roller&burnishing machine is suitable for boring ,skiving and burnishing the precision tubes such as hydraulic cylinders , air cylinders and so on . The processing accuracy can up to IT8~IT10 ,surface roughness after burnishing could reach Ra0.2~Ra0.4μm .
