TK (H) 69 series CNC floor boring and milling machine, machining center

  ● The overall structure of the machine  The series of machine tools using square ram type side hanging spindle box, single moving column, bed and platform split floor layout. The boring shaft is housed in the milling shaft and is supported in the square ram with the milling shaft. The column moves horizontally along the bed rail to form the x-axis feed movement. The spindle box moves vertically along the column guide to form the Y-axis feed movement. The boring axis moves longitudinally along the milling axis to form the z-axis feed movement. The square ram is closed along the spindle box The rectangular guide moves longitudinally to form the w-axis feed movement.

  ● Process assurance  Machine basic parts from the bed, slide, column, spindle box and other components, material for the HT250 3 ∞ high quality alloy wearable cast iron. The vibration aging of a hot furnace aging a vibration aging a roughing a vibration aging half of a finishing furnace a time of vibration aging finishing a work to eliminate the workpiece stress to ensure long-term operation accuracy of the machine.

● Headstock  The use of digital electro-hydraulic proportional valve and electromagnetic valve control, to achieve three precision compensation to ensure that the machine tool spindle high-precision requirements:　　

(1) single hammer flexible coupling spindle box, to achieve the spindle box center of gravity balance compensation.

(2) side of the ramps of the two hydraulic cylinders, to achieve square rams deformation compensation:

(3) Annex weight compensation.

● Transfer Method  X-axis feed for double helical gear meshing with high precision helical gear drive. X-axis <6m with high-precision pre-pressureless ball screw nut pair. Y, Z, W-axis feed mechanism for high-precision pre-pressure without gap ball screw nut (Y axis for the nut rotation). X, Y, w axis for the closed-loop control, z-axis semi-closed-loop control.

● Bearer way  X, Y, W axis guide for the multi-point closed hydrostatic guide, the friction coefficient is small. Adjustable spiral capillary static pressure throttling damping structure, easy to adjust.　

● Clamping method  X, Y, W axis feed mechanism for the floating clamping device, the spindle tool clamping for the disc spring group clamping, hydraulic release, safe and reliable.

● Numerical control system  According to user needs, select Siemens, Fanuc, France, Mitsubishi and other CNC system. Can achieve seven-axis control, any four-axis linkage function.

● Machine tool spindle  Spindle with three bearing high stiffness structure, the main support in the main, after the support, supplemented by high-precision spindle bearings. Make sure the spindle is high precision.　 

● Knife library  Can be equipped with 40, 50, 80 knife library. To achieve vertical and vertical tool change.

● Annex  Can be configured fixed table, CNC rotary table, right angle milling head, universal milling head, flat plate and other accessories, to improve the selectivity of processing technology.
