Screw grinder

CNC screw grinder is a CNC equipment designed specifically for precision screw machining. Its core function is to process various types of screws such as trapezoidal, rectangular, serrated, and ball screws through high-precision grinding technology, ensuring the pitch accuracy, lead accuracy, and surface smoothness of the screws, and meeting the high reliability and stability requirements of equipment for transmission components.

1、 Product Overview

CNC screw grinder is a specialized equipment used for grinding and processing screw parts. It achieves high-precision grinding of screws through a digital control system. Its working principle is based on numerical control technology, which can finely polish key parts such as the thread and outer diameter of the screw according to a pre-set program.

Structurally, it has a complex and intricate design. It usually consists of a bed, spindle system, feed system, grinding wheel, and numerical control device. The bed, as the basic support structure, provides a solid guarantee for the stable operation of the entire equipment. The spindle system is responsible for driving the workpiece or grinding wheel to rotate at high speed to achieve efficient grinding processing. The feed system can control the relative position movement between the workpiece and the grinding wheel, ensuring the accuracy and surface quality of grinding.

The device adopts a high rigidity bed and symmetrical structure design, equipped with a direct drive spindle unit and a high-precision ball screw feed system, which can accurately control the pitch error, cumulative error, and tooth profile of the screw; Equipped with a dedicated screw grinding CNC system that supports 3D modeling and process parameter optimization, it can achieve automated processing of complex curved screws. At the same time, it integrates automatic grinding wheel dressing and compensation functions, and corrects the shape of the grinding wheel in real time through diamond rollers to ensure consistency in batch processing.

In terms of performance advantages, CNC screw grinders have both high precision and high efficiency. They adopt segmented grinding technology and high-speed grinding technology, greatly reducing the machining cycle; Constant temperature cooling and oil air lubrication system effectively reduce grinding temperature and component wear, extending equipment service life. In addition, it supports automatic alignment and online measurement of workpieces, real-time monitoring of machining dimensions and dynamic compensation, further improving machining accuracy. It can be equipped with an automatic loading and unloading system to achieve continuous production of multi specification screws.

Whether it is processing large lead drive screws, precision ball screws, or difficult to cut materials such as titanium alloys and high-temperature alloys, CNC screw grinders can provide enterprises with transmission component solutions that meet equipment requirements based on processing performance. They are the core equipment for achieving efficient and high-precision manufacturing in the field of precision transmission.

2、 Workflow

1. Preparation: Confirm the setting and clamping of the grinder to ensure that the workpiece and grinding wheel are in the correct position.

2. Preliminary removal of excess by rough grinding: According to the process requirements, select a suitable grinding wheel for rough grinding to remove most of the excess and achieve a similar size of the workpiece.

3. Precision grinding and dressing: Replace the appropriate grinding wheel and perform precision grinding operation to achieve the required accuracy of the workpiece. This process usually requires multiple grinding steps, gradually reducing the feed rate of the grinding wheel until the required size and surface quality are met.

4. Inspection and measurement: Use measuring tools such as calipers, outer diameter gauges, etc. to inspect and measure the ground screw to ensure that its size and quality meet the requirements.

5. Cleaning and maintenance: After completing the grinding process, clean and maintain the equipment in a timely manner, including removing residual sand particles and lubricating parts.

3、 Important components

The important components of a screw grinder include the bed, grinding head, grinding wheel, control system, etc. The bed frame is usually made of high rigidity materials to ensure stability during the machining process; The grinding head and grinding wheel are key components for achieving machining actions; The control system is responsible for controlling the entire processing process, achieving automation and intelligence.
