VTC80A CNC vertical lathe

1. Machine Bed

The bed is made of high-quality gray cast iron HT300 grade, which has been heat-aged and stress-relieved. The material is high-strength and low-stress cast iron, and effective shock-absorbing measures are adopted.

2. Knife tower section

The tool holder has a variety of configurations, and users can freely choose according to their actual needs and usage habits.

Standard configuration: Taiwan horizontal 8-station tool holder, this series of tool holders is controlled by servo motors, can quickly select tools in both directions, hydraulically locked, and extremely rigid;

Taiwan vertical 4-station servo tool holder, this tool holder has an excellent design structure and high rigidity, uses servo technology for rotation, indexing and hydraulic locking, and the rotation and indexing are stable and accurate, especially suitable for processing parts in the automotive industry.

3. ​Chuck type

The standard chuck of this machine tool is a hydraulic chuck with a specification of 24 inches. The chuck is a waterproof chuck, and there is a sealing strip at the sliding fit between the chuck slide and the disc body, which can effectively prevent coolant from leaking to the spindle through the chuck and prevent chips from entering the sliding surface and damaging the slide.

4. Spindle section

The spindle unit of this series of machine tools adopts the current internationally advanced and mature structure in design. The front support of the spindle is composed of a double-row cylindrical roller bearing and a double-direction thrust angular contact ball bearing, and the rear support is a double-row cylindrical roller bearing; the bearing adopts imported precision spindle bearings, and the bearing is lubricated with imported high-speed grease. The axial and radial preloads of the spindle system can be adjusted with a nut, with high radial and axial stiffness. The radial clearance can be adjusted with the inner ring of the roller bearing to obtain the best processing accuracy and low working temperature.

The main motor of this series of machine tools drives the spindle to rotate through the imported synchronous belt, thereby ensuring the high efficiency, low noise and low vibration of the entire transmission system to meet the cutting requirements of various conditions such as low speed and high torque and high speed and high power of the machine tool. The spindle box and the base are connected together through holes, so that the spindle assembly of the machine tool has high rigidity.

5. Feed system

The X/Z axis is driven by a servo motor and is directly connected to the ball screw through an elastic coupling. The ball screw is installed with both ends fixed.
Both axis guide rails use Taiwan cylindrical rolling guide rails, which are four-way equal load type, with high precision, large load, and high roller fast moving speed. Its outstanding advantages are small size, high precision, and low maintenance cost. It is the preferred configuration for users who pursue high precision and high cost performance, and is particularly suitable for occasions with high requirements for part size consistency.

6. Safety protection

This machine tool has full shield protection, and considers multiple safety protection measures. The tempered glass design of the protective door ensures the safety of the machine and personnel.

When the machine tool encounters a sudden external power outage or self-failure, due to the special design of the control circuit, the machine tool axis cannot move, and the cooling motor, etc., if already in the "start" state, will enter the "stop" state; if already in the "stop" state, it cannot enter the start state automatically, ensuring the safety of the machine tool. In the event of an unexpected power outage or failure, the program menu stored in the computer will not be lost.

The machine tool is equipped with an alarm device and an emergency stop button to prevent various sudden failures from causing damage to the machine tool. Due to the reasonable design of the software, the alarm can be displayed in text and alarm number on the display, and indicated by the indicator light on the operation panel; the machine tool divides the alarm processing methods into three categories according to the situation: "emergency stop" for emergency alarms; "feed hold" for general alarms; and only "prompt" for operating errors.

II. Quality Assurance Conditions
