0 Comments

About two month ago, our engineer designed a mini cnc milling machine XK7116 with alfa controller. The XK7116 series represents a ground up rethinking of all the aspects of our best-selling mills, incorporating years’ worth of upgrades, optimization, and customer feedback.

The XK7116 have redesigned enclosures and stands, more power spindle (18000rpm electrical spindle).

 

Features

Small size and cheap price.
8 pcs automatic tool changer, air pump and lubrication pump.
18000 high spindle speed.
Taiwan linear guideway.

Machine structure:

1.Base

This mini CNC milling machine includes a base, a vertical column, a worktable, a headstock, a tool- magazine, an electric- cabinet, a control panel, and button station, a cooling tank, and a lubrication system. The electric cabinet installed on the backside of the machine. And the overall layout of which is compact in structure, convenient in operation, and small in the area occupied.

2.Worktable

The worktable is a key component to put the workpieces to be machined into feed motion along the X and Y direction to fulfill the cutting processing.

We apply the ball screw shaft and the screw pair to the pre-tightening force. To increase the axial rigidity and the transmission accuracy of the screw.

3.Column

The vertical column is also one of the base parts of the machine and on it, there is the guideway, along which the headstock moves upward and downward, and the ball screw pair of the Z-axis installed.

The feed motion of the headstock in the Z direction is fulfilled by a stepping motor, in which the stepping motor drives, through the coupling, the ball screw pair into the rotation. We apply the ball screw shaft and the screw pair to the pre-tightening force. In order to increase the axial rigidity and the transmission accuracy of the screw.

The guideway is also in a rectangular structure and is precisely after supersonic frequency hardening treatment, so as to increase its rigidity and wear resistance.
