Good Economic Benefit Of CNC Machine Tool

Characteristics and application of CNC machine tools

1. Characteristics of CNC machine tools

(1) High processing precision. NC machine tool is the number of instructions given in the form of processing. At present, the pulse equivalent of CNC machine tool is generally achieved. 001, and the reverse clearance of the feed transmission chain and the screw pitch error can be compensated by the NC device, CNC Machine so the NC machine tool can achieve high machining accuracy. For medium and small CNC machine tools, the accuracy of positioning is generally up to 0.03, and the repeatability of the positioning accuracy is 0.01.

(2) Adaptable to processing objects. The NC machine tool changes the processing parts, only need to redesign the program, the new program can realize the new processing of the parts, the complex structure of the single piece, small batch production and new products to provide a great convenience. CNC Machine For those ordinary manual operation of ordinary machine tools difficult to process or can not be processed precision complex parts, CNC machine tools can also achieve automatic processing.

(3) high degree of automation, low labor intensity. NC machine tool to the parts of the process is done in advance programmed automatically completed, in addition to the operator to place a perforated belt or operation of the keyboard, loading and unloading work pieces, the middle of the key procedures to detect and observe the machine operation, no need for complex repetitive manual operation, CNC Machine labor intensity and tension can be greatly reduced, In addition, CNC machine tools generally have good safety protection, automatic chip, CNC Machine automatic cooling and automatic lubrication device, the working conditions of the operators have also greatly improved.

(4) High production efficiency. The time required for the machining of parts includes both the maneuvering time and the auxiliary time. The speed and feed range of the spindle of NC machine tool is larger than that of ordinary machine tools, so the most advantageous cutting dosage can be chosen for each process of NC machine tool. Because of the good rigidity of the NC machine tool, the large cutting capacity is allowed, CNC Machine which improves the cutting efficiency and saves the maneuvering time. Because of the moving parts of the NC machine, the empty travel speed is fast, so the workpiece clamping time and auxiliary time are less than the general machine tools.

The machine tool is hardly readjusted when the machine tool is replaced by a number of pull machines. CNC machine tool processing quality is stable, generally only do the first part of the test and the process between the key dimensions of the sampling test, thus saving downtime inspection time. CNC Machine When machining the machining center, a machine tool realizes the continuous processing of multi-channel process and the improvement of production efficiency is more obvious.

(5) Good economic benefit. Although the value of CNC machine tools, CNC Machine processing time to each part of the equipment depreciation fee is high, but in the case of single piece, small batch production: ① use CNC machine tool processing, can save the marking work hours, reduce adjustment, processing and inspection time, save the direct production costs; ② using CNC machine tools to process parts generally do not need to make special fixture, The cost of process equipment is saved. ③ NC machining accuracy and stability, reduce the scrap rate, so that the production costs further decline. ④ CNC machine tool can be used to achieve more than one machine, save plant area, CNC Machine save construction investment. Therefore, the use of CNC machine tools still sting to obtain good economic benefits.

2. Application of digital Pull machine

CNC machine tools have a number of ordinary machine tools do not have many advantages. The scope of its application is expanding, but it can not completely replace the ordinary machine tools, but also not the most economical way to solve all the problems in machining. CNC machine tools are most suitable for machining parts with the following characteristics:

(1) Many varieties, CNC Machine small-scale production of parts.

(2) Parts with complex shape structure.

(3) parts requiring frequent modifications.

(4) Critical parts that are expensive and not allowed to be scrapped.

(5) Design and manufacturing cycle of short needed parts.

(6) Large volume, high precision parts.
