One.Use of machine tools

On the basis of inheriting the advantages of rigid frame, symmetrical structure and strong stability, the machine tool has introduced the international advanced concept of dynamic rigidity and optimized the design of mobile parts. The machine tool has great torque and fast response characteristics, and it is suitable for various mechanical processing fields, such as automobile, mould, aerospace, military industry, hardware and so on.

Two. Overall layout of machine tools

The overall layout of the machine tool is a frame structure, the base is fixed, and the worktable is moved from the base to the base of X.

Three. The structural features of the machine tool
1, high rigidity, long lasting accuracy retention
The machine is mainly large: base, table, column, beam, slide, slide are made of high quality resin sand molding, high strength and high quality cast iron, with heat treatment process improvement to eliminate the residual stress, and the layout of sufficient reinforcement plate, ensure the machine has enough strength and rigidity and high stability.
The XY axle adopts imported heavy load roller guide, which has strong rigidity and good dynamic precision.
The three axle drive adopts Taiwan large diameter grinding double nut ball screw rod, which has compact structure, smooth movement and high precision. The silk rod support is supported by the Japanese imported silk rod support bearing, which is prestretched at both ends to eliminate the precision loss caused by the thermal elongation. A stable high rigid mechanical transmission system is made up.
The staircase structure, the cross section of the beam is large, the distance of the guide rail is large, the center of the spindle is short, the turning moment is small, and the structure has a good rigidity.
The high rigidity Taiwan produces the Longmen special-purpose spindle, uses the lubricating grease lubrication, enables the spindle bearing to obtain the constant and reliable lubrication, is economical and environmental protection, and has realized the long term free maintenance.
  
2, high precision and high dynamic response characteristics
The spindle is supported with three points to make the spindle get high rigidity and high spindle rotary precision.
The XY axis roller guide has high accuracy, large load and only 0.002 friction coefficient. It reduces the phenomenon of low speed crawling and achieves good positioning accuracy and high dynamic response characteristics.
The Z axis adopts the structure of the nitrogen balance cylinder, and its dynamic response speed is higher than the traditional hydraulic balance structure, and its structure is simple and the maintenance is convenient.

Acceptance criteria and methods
1. The acceptance of machine tools is carried out in two times: pre acceptance and final acceptance.
2, pre acceptance in Kunshan Liangjiang Pml Precision Mechanism Ltd, machine tool inspection requirements refer to "GB/T25658.1-2010 CNC machining center milling machine test conditions of precision test, such as" special requirements according to an agreed sample test cutting test, and the two sides agreed to the machining accuracy and process capability.
The 3 and final acceptance in the user plant, installed and debugged by the Kunshan Pml Precision Mechanism Ltd will send, in principle only acceptance precision: if any environment and corresponding software and hardware facilities, we can check with precision table.
4. The samples, cutting tools and special fixtures required for sample cutting are provided by the buyer, except for special stipulations.
5. Note:
1) if the machine is shipped to the buyer's factory for 30 days, the installation and commissioning of the machine can not be carried out because of the buyer's cause, which is regarded as the acceptance of the machine tool.
2) the precision index of the machine tool is tested according to the acceptance accuracy table of the technical agreement. If the buyer has any objection to the test result, the buyer can prepare the testing equipment and appoint the national certification inspecting party to recheck. If the test result is consistent with the accuracy table of the technical agreement, the cost incurred during the inspection period will be borne by the buyer. The buyer must seal the machine tool before testing, and if the buyer opens the machine, it is deemed to be qualified.
3) it is the basic requirement for the precision processing to keep the ambient temperature as the uniform value. According to the rule of GB/T17421.3-2009 (ISO 1:2002), all linear measurements should be done at room temperature of 20 degrees, and it is required to measure the heat balance between the measuring instrument and the tested object (such as machine tool) and the surrounding environment.
