HTC16/32/45/54 series slant bed CNC lathes are used for the machining of cylindrical, arc, and conic surfaces, grooves and threads in either metric or inch execution, on rotary parts. These machine tools can batch process with high efficiency and accuracy, and are therefore suitable for such industries as automotive, electronic, aerospace, military, etc.
The incorporation of an integral slant bed design ensures that the CNC lathes maintain accuracy while taking heavy cuts. Wide rectangular box-type guideways prevent twisting, bending and lifting of the tool-post. Guideways are laminated with anti- friction material to ensure the optimum positioning accuracy during rapid feeding.
Linear guideways permit high speed movement, minimizing friction resistance and thermal deformation, improving machining accuracy over the longer term.
X and Z axis servomotors are connected to precision ball screws with flexible couplings, maintaining high cutting accuracy.
The design of the spindle also reduces thermal deformation, thus keeping the spindle axis stable over long work cycles.
The horizontal-axis turret incorporates a large disc coupling to fix its position, thus ensuring precise positioning and little deformation due to cutting pressures.
The tool detection device can automatically input the tool-tip position into the CNC, which greatly reduces the adjustment time resulting from a tool change. It can also compensate automatically for tool wear. Our horizontal CNC lathe has fully enclosed workspace, and separate cooling tank and chip conveyor, which prevent the machine from losing accuracy from cutting heat.
