Because the rigidity of 716 vertical machining center will directly affect the production efficiency and the machining accuracy of machine tools, the machining speed is much higher than that of ordinary machine tools, and the motor power is also higher than that of ordinary machine tools with the same specifications, so the rigidity of its structure design is much higher than that of ordinary machine tools. When ordering can be according to the process requirements, the maximum allowable torque, power, axial force and feed force, according to the manufacturer to provide the value of checking. In order to obtain the high rigidity of machine tools, they are often not limited to the size of parts, but choose the machine tools with 1 to 2 specifications larger than the size of parts.
Numerical control system, is the core brain of 716 vertical machining center operation, numerical control function is divided into basic function and selection function. Basic function is inevitable to provide, and selection function only when the user chooses these functions, the manufacturer will provide.
The function of the NUMERICAL control system must be selected according to the performance of the machine tool. When ordering, the required functions should be fully ordered, and can not be omitted. At the same time, the utilization rate is not high enough to cause waste, but also need to pay attention to the relevance between the functions. Performance varies widely among the CNC systems available. Should choose according to need, cannot one-sided pursuit high target, lest cause waste. Multiple machine tool selection, as far as possible to choose the same manufacturer of NUMERICAL control system, so that the operation, programming, maintenance are more convenient.
716 vertical machining center of the main processing object
(1) box parts: box parts generally refers to the parts with more than one hole system, internal cavity, in the direction of length, width and height have a certain proportion.
(2) Complex surfaces: complex surfaces are difficult or even impossible to be processed by ordinary machine.
(3) special-shaped parts: special-shaped parts are irregular shape parts, mostly need point, line, surface multi-station mixed processing, such as fork.
(4) plate, sleeve, plate parts: with keyway, or radial hole, or end face distribution of holes, curved plate sleeve or shaft parts, such as flange sleeve, with keyway or square head shaft parts, and plate parts with more porous processing, such as all kinds of motor cover. Vertical machining center should be selected for disk parts with distributed holes and curved surfaces, and horizontal machining center with radial holes is optional.
(5) Parts put into production periodically: when processing parts, the time required mainly includes basic time and preparation time, among which, preparation time accounts for a large proportion, such as: process preparation, programming parts, the first test cut, etc., these time is very long, so the content of these time can be stored for repeated use in the future. In this way, the time can be saved later when the part is processed. The production cycle can be greatly shortened.
