The structure of drilling and milling machine is made up of six main components, including bed, base, worktable, milling head, cooling and lubrication, electrical system.

Servo system is essentially a follow-up system, only the controlled quantity is displacement or its derivative to time.If you ask what a follower system is, it is the output of a system that reproduces the input signal as fast and precisely as possible， It is measured by overshoots and delays. Servo

CNC lathe is the product of mechatronics, advanced technology and complex structure. The faults of CNC machine tools are various, each of which is different. The causes of faults are generally complex, which brings many difficulties to the fault diagnosis and maintenance of CNC machine tools.In orde

1. Vertical CNC milling machineVertical CNC milling machine spindle axis is perpendicular to the horizontal plane, is the CNC milling machine spindle axis is perpendicular to the horizontal plane, is a common form of layout in CNC milling machine, widely used.From the point of view of the number of

(1) Boxlike partsThere are many kinds of box-type parts. Generally, multi-station hole system and plane machining are required with high precision, especially the requirement of shape accuracy and position accuracy is more stringent. Usually, the box-type parts need more cutters through milling, dri

1. Before working, it is necessary to check whether each system of the machine tool is safe and easy to use, whether the position of each hand wheel handle is correct, whether there are obstacles in the fast feed, and whether each limit switch can play a role of safety protection.2. When starting th

Working principle of common milling machine:The main motion of the milling machine is the rotation of the milling cutter, On most milling machines (such as vertical lifting table milling machine), the feed motion is realized by the linear motion of the workpiece perpendicular to the axis of the mill

1. Surface grinder: Surface grinding machine is a kind of grinding machine which clamp the workpiece on the worktable or fix it on the electromagnetic worktable by electromagnetic force, and then grind the workpiece surface with the periphery or end face of the grinding wheel. 2. Centerless grinder:

The drilling and milling machine is mechanical equipment combined with drilling, milling, boring, and grinding, and suitable for processing small and medium-sized parts.

CNC lathe is the abbreviation of digital program control lathe. It combines the characteristics of a universal lathe with good versatility, a precision lathe with high machining accuracy, and a special lathe with high machining efficiency. Typical parts processed by CNC lathes are generally sleeve
