The drilling process of furniture refers to the processing of various holes, grooves and slots in furniture. Drilling is an important process in furniture production. The level of drilling processing technology is one of the important indicators to measure the technical level and technical management level of a furniture enterprise.
At present, except for a few large enterprises, most of my country's furniture manufacturing enterprises are small and medium-sized enterprises. In this case, in order to save materials, reduce production costs and improve product quality, most furniture manufacturing enterprises have adopted various processing technologies and equipment to meet production needs.
In furniture production, drilling processing technology is a relatively common processing method. However, due to various reasons, this processing method also has some shortcomings and deficiencies. Let us introduce this processing technology below.
Furniture drilling processing can generally be divided into three categories: (1) manual drilling; (2) electric tool drilling; (3) mechanical drilling. Let us take manual drilling as an example to introduce the characteristics of these three processing methods.
When drilling manually, different drill bits should be selected according to the shape and aperture size of the parts. During processing, the following methods are generally used:
Before drilling, the equipment should be checked first to ensure that the technical condition of the equipment is good, mainly including: the mechanical state of the drilling machine, such as whether the spindle accuracy, speed, and feed system of the drilling machine are normal; whether the cutting part of the drilling machine has cracks or wear, and whether the chuck and clamping device are working properly; whether the worktable and base of the drilling machine are normal; whether the center line of the drilling machine spindle is consistent with the center line of the workpiece.
Secondly, the drilling machine should be checked for accuracy to determine the dimensional accuracy of each part.
Generally, when the drilling diameter is less than 6 mm, it is measured with a micrometer; when the drilling diameter is greater than 6 mm, it is measured with a vernier caliper; when the drilling diameter is greater than 12 mm, it can be measured with a vernier caliper and a micrometer at the same time. In order to ensure the drilling size accuracy of the workpiece, the hole size should be inspected and checked before drilling.
In actual production, the drilling operation is generally controlled by the spindle on the drilling machine, but it can also be manually operated by the operator. When operating manually, pay attention to the force, speed, tool change direction, etc. When drilling, the operator must concentrate, carefully observe the changes in the position and speed of the workpiece, and make records in time so that the spindle speed and feed speed can be adjusted at any time.
In the post-drilling processing process, the most commonly used is: polishing with a grinder. The purpose is to make the surface of the processed hole smooth and clean, which is conducive to the processing of the next process.
Secondly, grinding the edge of the hole left after processing with a file and a grinding wheel is also an important process. For some larger holes or holes with burrs on the edge of the hole, they must be polished with a file.
In addition, after drilling furniture, in order to make the surface of the processed product flat and smooth, the workpiece must be finished and polished. Specific methods include: grinding, grinding with a grinding wheel, polishing, etc.
The purpose of post-drilling processing is to eliminate processing marks and surface defects and improve product quality.
Drilling processing technology is a traditional processing method of furniture manufacturing enterprises, and it is also an important process of the enterprise, and its status is very important. However, due to the large variety and quantity of furniture products, the various drilling processing methods, and most of them are developed on the basis of traditional processing technology, there are still many problems in the improvement and improvement of its processing methods. In order to overcome these problems, furniture enterprises should strive to adopt new processing technology and equipment, and adopt advanced processing technology in the future to improve product quality, reduce production costs, shorten production cycles, and improve enterprise economic benefits.
