Clk6440/1 (30° slant bed) CNC Lathe Machine

Product Description

This machine is a fully functional slant bed CNC lathes, especially suitable for small and medium-sized plate, short shaft parts of high speed, high precision machining.There are two straight axis X, Z, be able to complete functions by one clamping for: turning, drilling, boring, tapping, reaming, and other.
The 30 ° slant bed and base is whole casting molding. 20 mm wall thickness, 4 square type structure, optimal layout of reinforcement through the finite element analysis, the high strength cast iron material, resin sand molding, through full secondary time aging and natural aging, so,the basis of a machine with high rigidity ,ensure the stability of the machine use for a long time;
2.the main structure
1)The base is whole casting molding---30 °slant bed and pedestal. 20 mm wall thickness, 4 square type structure, optimal layout of reinforcement through the finite element analysis, the high strength cast iron material, resin sand molding, through full secondary time aging and natural aging, so the basis of a machine with high rigidity ,ensure the stability of the machine use for a long time;
2)X, Z axis adopt linear guide way with high precision, high load capacity, high reliability, match automatic forced lubrication, which greatly reduce the frictional resistance feed movement, improve machine precision and life; the friction coefficient of sliding friction can be reduced to fiftieth of the original, feed speed and positioning accuracy is higher.
3) High speed and high precision, high rigidity shell type spindle unit, spindle with chromium molybdenum alloy material, spindle bearing adopt NSK specified double row cylindrical roller bearing and P4 level high speed precision angular contact bearings pairs, use NSK high-speed specified grease, resistance to high temperature and high speed. Spindle unit assemble at a constant temperature room, running-in 36 hours in a constant temperature after assemble, through continuous 36 hours test run after install on the machine, make sure that the performance of high speed and high precision and reliability. The spindle hole diameter is 64mm and Max. Dia. through bar is 51mm, make the machine with larger bar through range.
4)Gang tools , long horizontal stroke, can configure multiple row of cutter holder.
5) The machine tool outside protection guard adopts full protective structure design, convenient operation, safe and reliable;
6) Operating system on the principle of human body engineering, operation box independent design, easy to operate
