PT46/52/56D Back chip removal CNC lathe
Features：
The machine frame features a proven,rigid 45°integral slant bed construction casted by premium resin sand cast-iron to ensure maximum rigidity and easy chip removal.
Adopt Germany-FAG/Japan-NSK P4 level imported high precision spindle special bearings to ensure optimum turning results,even at high axial and radial loads.
High-performance preloaded ball screws are quipped with precision bearings to ensure sustained,smooth,vibration-free operation.
An automatic lubrication system maintains optimum tool temperature for long tool life,reduces the operator’s workload and simplifies maintenance.
The workspace is enclosed on all sides with easy access through a large sliding door for set-up,tooling and unloading.
