The machine adopts rear-mounted vertical guideway arrangement, which improves machining rigidity and facilitates machining chip flow and conveyance.
Stainless steel scale-type armour guard is installed on the guideway.
The main motion of the screw raceway machining is through the spindle (C-axis) rotation and Z-axis linear motion of the linkage to form a helix.
The rotary motion of the C-axis is transmitted from the servo motor to the headbox after deceleration by a planetary reducer, and then to the spindle after deceleration by a two-stage backlash gear to drive the spindle rotation. A precision rotary encoder is installed at the rear end of the spindle to detect the angle of the spindle and realise the closed-loop control of the spindle drive part.
The workpiece is clamped by hydraulic taper sleeve with 16, 20, 25, 32, 40, 50, 63, 80, 100 ferrules.
Z-axis movement through the servomotor by planetary gear deceleration drive ball screw vice rotation, push the cross drag plate to move, the cross drag plate installed in the drag plate, Z-axis moving direction to install precision grating, grating installed in the bed away from the operator's side, and the Z-axis direction of the servomotor to form a closed-loop control. Stainless steel shield is adopted on the surface of bed guideway.
Rotary milling ball screw using 2 groups of servo-electric cylinder support mechanism auxiliary support, the servo lifting electric cylinder involved in the system programme control, processing when the drag plate close to a servo-electric cylinder, auxiliary support mechanism automatically return to the lower limit position; when the drag plate once away from the servo-electric cylinder auxiliary support mechanism and automatically return to the support position. The support part is installed with a blowing device to blow away the iron chips falling into the support to prevent damage to the machining surface.
Cyclone milling tool feed movement, through the X-axis direction of movement is achieved by the servomotor through the right-angle planetary reducer deceleration to the ball screw vice, push the cross drag plate in the drag plate movement, the drag plate installed on the cyclone milling device. X-axis direction of the installation of precision scale, and X-axis direction servomotor closed-loop control, to achieve the precise feeding of the tool feed movement. The centring jaw device is installed on both wings of the cross drag plate, distributed on both sides of the cyclone milling mechanism, used to support the clamping of the workpiece. In order to improve the clamping rigidity and machining accuracy, the alignment clamping bracket should be as close as possible to the milling cutter position. When the workpiece specification is different, the corresponding centring jaws are replaced, and the centring jaws are automatically centred when they are installed.
The centring clamping device adopts servo motor and left and right ball screws for centring clamping, and the size of the clamping force is adjusted by the current size of the servo motor.
Head box clamp clamping workpiece head to the rotary milling blade centre distance of not more than 260mm, rotary milling blade centre to the rear of the clamping device centre distance of not more than 200mm, in order to improve the material utilization rate, you can once rotary milling through the length of a screw light blank and then cut into several segments for further processing and then use.
The rotary motion of the cyclone cutter disc is driven by the spindle frequency conversion motor through the belt deceleration, driving the cyclone cutter disc rotation. The rotational speed of the cutter disc is adjusted by the driver and the speed is set by the system programme. The adjustment of the helix angle of the cutter disc is automatically completed by the servo motor driving the rotary axis through the reducer.
Specification of cutter disc: φ16~φ32/φ32~φ50/φ63~φ80/φ80~φ100.
The workpiece is cooled by air-cooling.
The chip outlet is equipped with a chain-plate conveyor to send the machined chips to the chip box.
In addition to the basic functions of the machine software, the machine should have the functions of centre diameter compensation and stroke deviation compensation at the same time, with one point compensated every reference length.
Machine cables, pneumatic pipelines and hydraulic pipelines are beautifully, generously and neatly arranged.
The machine tool adopts fully enclosed protection. The electric box is installed at the back of the machine, flush with the chip stopper.
The appearance of the machine requires practical and beautiful.

CNC high-precision rotary milling machine for milling ball screw raceways
|
|
|
This cyclone milling machine is modelled on the German Lehigh machine, featuring high precision and high efficiency machining, and is currently the only one in China for the ball screw industry.
Ball screws are increasingly widely used in various fields of machinery due to their mature technology and high precision/.
The machine adopts rear vertical guideway arrangement to improve machining rigidity and facilitate chip flow and conveying. The guideway is equipped with stainless steel scale-type armour guard.
The machine adopts two-axis linkage design; Z-axis and X-axis adopt stepless speed change. The main motion of the screw-roller machining is through the rotation of the main spindle (C-axis) and the linkage of the Z-axis to form a helix.
