Multi-spindle drilling machine is a drilling machine with vertical spindle arrangement and fixed center position, which is referred to as vertical drill. The vertical drill with multiple drill shafts is called multi-spindle drilling machine. It is often used for machining holes of medium and small workpieces in machinery manufacturing and repair factories.
Before the multi-axis drilling machine is processed, the position of the workpiece on the workbench must be adjusted so that the center line of the processed hole is aligned with the tool axis. During processing, the workpiece is fixed, the spindle rotates in the sleeve and makes axial feed with the sleeve. The position of the worktable and headstock can be adjusted along the column guide rail to adapt to the workpieces of different heights.
There are two types of vertical drills: square column vertical drill and cylindrical vertical drill, and there are many variants such as row type, multi-axis coordinate and turret. ① Row drilling machine: generally, 2~6 columns and headstock are arranged on a common base. Each spindle processes different holes on the same workpiece in sequence or carries out various hole processing procedures respectively, which can save time for tool replacement and can be used for medium and small batch production. ② Multi-spindle vertical drilling machine: multiple spindles of the machine tool can adjust the position of the spindle center according to the processing needs. The spindle box drives all the spindles to rotate for simultaneous processing of multiple holes for mass production. ③ Coordinate vertical drilling machine: it is formed by adding a cross table that can move vertically and horizontally on the square column vertical drilling machine, and it can be drilled according to the coordinate size. ④ Turret vertical drilling machine: It adopts program control or digital control to make the turret head with different tools automatically rotate, the spindle automatically change the speed and feed rate, and the workpiece automatically adjust the position, so as to realize the automatic cycle of multi-process processing.
Basic features of multi-axis device
According to whether it is fixed, it can be divided into fixed type and adjustable type;
According to its shape, it can be divided into U type, T type and A type
U-type multi-axis device: if the hole spacing is straight or rectangular, please use a square universal multi-axis device to prevent the displacement foot from extending too long and causing insufficient stress. The usage is the same as the circle type. (Try to match the design of working hole spacing)
T-type multi-axis device can be used for drilling and tapping. It is light and exquisite, easy to operate and does not take up space. It is very popular.
Type A four-axis adjustable multi-axis device uses elastic collet type, so the adjustment distance can be reduced, and the distance between the two axes can be adjusted to 18mm, which is suitable for small distance processing
