T (X) 69 series of ordinary, digital floor boring and milling machine

  ● 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, and the boring axis moves longitudinally along the milling axis to form the z-axis feed motion. The square ram is moved longitudinally along the main shaft of the closed box to form the w-axis feed movement.

  ● Basic parts of the process of protection The basic parts of the machine are composed of bed, slide, column, spindle box and so on. The machine tool is large. HT250 300 High quality alloy wear-resistant cast iron, which is subjected to vibration aging time. Furnace aging effect of a vibration aging finishing, eliminating the workpiece stress, to ensure long-term operation accuracy of the machine.

● Headstock The use of electro-hydraulic proportional valve control, single weight flexible coupling spindle box, spindle box to achieve the balance of center of gravity compensation to ensure that the machine spindle high precision requirements.

● transfer method Y, Z, W axis feed mechanism are used high-precision pre-pressure non-gap ball screw nut pair (Y-axis for the nut rotation), X-axis with double-gear reducer gear meshing high-precision helical gear.

● Bearer way X, Y, W-axis guide with multi-point closed hydrostatic guide, dynamic and static friction coefficient quite. Make sure there is no crawling at low feed. To ensure high accuracy. Multi-point closed static pressure guide with adjustable spiral capillary static pressure throttling damping structure, easy to adjust, take up a small space.

● Clamping method X, Y, W axis feed mechanism with floating clamping device, clamping fast and reliable. To ensure that the film thickness is not affected. Spindle tool clamping using disc spring group clamping, hydraulic release, safe, reliable, fast.

● Machine tool spindle  Spindle with three bearing high stiffness structure, before the main support, after the support, supplemented by high-precision spindle bearings to ensure high precision spindle.　

● Each axis feedback Each axis can be used to achieve full closed-loop position feedback grating, or the use of encoder to achieve semi-closed-loop position feedback.

● Electrical control  The AC servo controller drives the variable frequency motor to realize the smooth operation of each axis.
