Main part of the machine
Mobile table is the key part of the sliding table saw, and it is the biggest difference from the ordinary circular saw. The main part of the mobile table consists bracket, lower guide rail, roller, sliding table and other parts;
Its significant characteristics are :
- Easy to operate and labor-saving, with long sliding distance, cut;
- With a stable and light trailer, operating smoothly;
- The setting of the mobile table and the fact that main saw blade can be adjusted by 45 degrees expand the use of the saw machine. Manufacturers equip some saw machines with milling devices for processing grooves between 30-50mm in width.
Operation characteristics of sliding table saw
Manufacturers have tested quality sliding table saws for equilibrium and dynamic balance, eliminating the need for a foundation. The workpiece is placed on the mobile table, which is manually pushed to feed it during processing. Operation is convenient, but we must always prioritize safety during use to prevent accidents.
Main technical parameters
The specifications of sliding table saw have become a standard. The main parameter is the maximum saw length-the general range: 2000 ~ 5000ram. China’s industry standard JB/ t9950-1999 “woodworking Sawing Machine Parameters with Mobile Table” stipulates 3 specifications: 2000mm, 2500mm, 3150mm.
The direction of the sliding table saw design
Since the 1980s, China has developed sliding table saws, with 20 companies producing 4000 units annually, replacing imports.
Most Chinese enterprises began designing sliding table saws by surveying foreign prototypes, then improving based on usage issues. However, we have not thoroughly understood some stress relations. Most enterprises have not carried out static and dynamic mechanical calculation, lacking of necessary theoretical basis. In order to improve the shortcomings existing in the design and design with good performance, we suggest the companies should sum up the existing experience and adopt popular CAD and optimization design and dynamic design. With the rapid development and application of computer, we can use software to calculate the stress relation. As for the main saw blade and the crossed saw blade, its shape is not complicated, and can be approximately regarded as an elastic body. We calculate vibration stress characteristics and obtain modal parameters through testing and analysis to improve accuracy.This foundation enables development of sliding table saw design software to create high-quality, theory-based saws.
In China, there are companies that can apply the cutting-edge tools to independently develop new sliding table saw: Qingdao Yongqiang woodworking machinery, Ma woodworking machinery, Nanxing woodworking machinery and etc. Based on advanced foreign models and domestic needs, enterprises developed products like Yongqiang’s MV8-90, Ma’s MJ6132, and Nanxing’s MJ6132Y.
