Vertical Metal Milling Machine
Vertical metal milling machine, also known as rocker arm milling machine or universal milling machine, is a lightweight general-purpose metal cutting machine tool. Its compact structure, small size, and high flexibility make it widely used in industries such as mechanical processing, molds, instruments, and meters.
- Product Introduction
The following is an introduction to vertical metal milling machine and a detailed explanation of troubleshooting methods:
Introduction to vertical metal milling machine
A vertical turret milling machine (also called turret mill or vertical turret mill) is a highly adaptable milling machine designed for precision machining. Its defining feature is a rotatable turret head that allows the spindle to swivel horizontally (360°) and tilt vertically (±45°), enabling multi-angle operations without repositioning the workpiece.
Key Features：
Turret Head – The turret machine's head rotates for flexible cutting at various angles.
Vertical Spindle – Performs face milling, drilling, and slotting with vertical tool alignment.
3-Axis Movement – Manual or CNC-controlled X-Y-Z axes for precise positioning.
Rigid Construction – Heavy-duty cast iron frame ensures stability during heavy cuts.
Wide Tool Compatibility – Supports end mills, face mills, drills, and taps.
Electrical malfunction:
■ Phenomenon: Motor not turning, switch failure, short circuit in the circuit, etc.
■ Exclusion method: Check if the power cord is in good contact and if the motor is overheated; Check if the switch is damaged and if the circuit is short circuited; Replace damaged switches or repair short circuited circuits.
Mechanical malfunction:
■ Phenomenon: The spindle does not rotate, the slide table moves unevenly, and the guide rail is worn.
■ Exclusion method: Check if the spindle is stuck and if the bearings are damaged; Check whether the slide guide rail is worn and whether the screw is loose; Replace damaged bearings or repair worn guide rails; Tighten the loose screw.
Abnormal machining accuracy:
■ Reason: feed unit has been changed, zero offset is abnormal, axial reverse clearance is abnormal, motor operation status is abnormal (electrical and control parts are abnormal), mechanical failure (such as screw, bearing, shaft coupling and other components have faults), etc.
■ Exclusion method: Check the parallelism of the workbench, the parallelism of the main axis relative to the workbench, and the perpendicularity of the lifting platform relative to the workbench; Check and adjust the tightness of the milling head belt, pressure plate, and insert strip to ensure they are suitable; Check and adjust the limit block and screw clearance; Compensate for the existing gaps, adjust the servo gain parameters and pulse suppression function parameters.
Applications：
Precision milling of flat, angular, or contoured surfaces.
Slot & keyway cutting (e.g., T-slots, dovetails).
Drilling, boring, and tapping operations.
Prototyping & small-batch production in toolrooms and workshops.
Advantages：
Versatility – The vertical turret mill handles complex geometries in a single setup.
Space-Efficient – Compact compared to horizontal milling machines.
User-Friendly – Ideal for both manual operation and CNC upgrades.
