Linear guideways are commonly used in the machine tool industry as part of linear modules. We usually refer to these components as "linear guides," which consist of two parts: the slider and the carriage. The carriage contains internal recirculating balls or rollers, and the length of the slider can be customized. It is a modular component, a standardized and serialized product line produced by manufacturers, which can be mounted on machines and replaced after wear. A linear guideway machining center is a machining center equipped with rolling guides (or linear guides).
Modern CNC machine tools require hydraulic and pneumatic transmission devices in addition to the CNC system to assist in the full automation of the machine's operation. The hydraulic and pneumatic transmission devices should be compact in structure, reliable in operation, and easy to control and adjust. Although their working principles are similar, their application ranges differ.
Key Features of Linear Guideway CNC Lathe:
1. Machine tools integrate mechanical, electrical, and pneumatic functions into one unit, featuring ergonomic layout design based on human-machine engineering. They are fully enclosed for safety, have a compact structure, save space, are easy to operate, and convenient to maintain.
2. The base features an integral high-rigidity cast iron structure, ensuring smooth chip removal and rational cutting space.
3. The linear guide offers fast motion speed, low rolling resistance, no creeping, and easy lubrication. After prolonged use, there is minimal loss in precision. Steel-inlaid (some with plastic coating) guides are commonly used under heavy loads, especially where lubrication is crucial. During processing on a linear guide machining center, the guide experiences rolling friction with point or line contact, resulting in a small contact surface and reduced friction. This is primarily applied in high-speed machining and the mold industry, catering to small cutting volume and rapid cutting mechanical processing.
4. The spindle is equipped with high-speed angular contact bearings and precision dynamic balancing, ensuring smooth and stable rotation at high speed, while reducing thermal deformation.
5. The machine tool's longitudinal and lateral movements are both driven by AC servo motors directly connected to ball screws. The ball screw bearings are equipped with precision bearings, ensuring high-precision transmission.
6. The machine tool is equipped with a high-performance automatic intermittent lubrication system, which ensures timely lubrication of the bed guide rails and X/Z-axis lead screws, maintaining optimal lubrication conditions for all guide surfaces and longitudinal and transverse screws at all times.
7. Machine tools feature a row-type tool holder, making tool arrangement and adjustment quite convenient. The tool holder is equipped with an automatic material feeding device, which can be easily controlled by the CNC system for online collaboration automation. The tool holder operates without fault, contributing to enhanced machine tool productivity.
8. The clamping of workpieces on the CNC lathe with linear guide uses spring-loaded chuck pneumatic clamping, ensuring reliable and efficient clamping.
