Machine main features:
1.XH-L716 bed and other key components are used dense bake castings. Casting material grade is FC-30. Casting structure using one-piece molding technology, box structure, its advantages: high stability, small deformation, can effectively inhibit vibration, greatly extend the service life of machine tools. Coupled with the unique structure of the corresponding precision components, cutting performance. In strict accordance with the ISO static precision test standards for the production of strict control of each process excellence. The factory machine in line with national JB / T8771.2-1998 standards
Note: bimetal castings casting process control its application
Casting process control of dense metal casting (Meehanite Metal Casting); bimetallic casting is subject to a series of stringent casting process control, such as the carbon graphite (GC) and carbon content (CC) content of the iron material control; metallurgy quality Ie Cleanness and Under Cooling degree control; Wedge Value control after inoculation with CA-SI; 5 elements, alloying elements and nitrogen (N) content Control, etc., after re-casting extremely easy to Di wave expected to wave iron base and graphite distribution, improve the mechanical properties. In addition, in order to prevent deformation after processing, the castings are completely annealed to eliminate internal stress.
Secret drying GC40 type (GC275) of the application
Baking type GC40 most suitable for casting thickness of 10-15mm homogeneous castings. Such material structure of dense, good strength, low coefficient of friction, and with self-lubricating, so the surface hardness after quenching HRC48-52, used in the metal surface friction caused by thermal shock on the workpiece.
1. The head, fuselage, saddle, base, workbench, use advanced cast iron FC-30 material, and the stress relief treatment, mechanical precision and stability, good rigidity.
2. Spindle head design, the use of box-type body, the internal ribs to be strengthened, high rigidity, solid, suitable for precision machining and heavy cutting.
3. X / Y axis with linear ball slide and Y axis feed axis four tracks, Z axis roller track. Excellent full stroke support, with high rigidity, low noise, low friction characteristics, can do fast displacement and Get the best rounding accuracy.
4. All three axes adopt precision ball screw preloaded by C3 double nuts, with pre-tensioned design of both ends support seat, it can eliminate transmission backlash and compensate the error caused by temperature rise in advance, so as to ensure the positioning accuracy.
5. The Division of the machine produced by Renishaw laser measurement test, three-axis travel for the machine part of the 100% full inspection, internal control inspection standard VDI 3441 3 σ round trip six round trip test, to eliminate the greatest extent Deviations of the machine itself to ensure the positioning accuracy of the machine.
6. Circular measurement test, the use of circularity analyzer / Renishaw, correction of roundness and machine geometry accuracy, to test to ensure the accuracy of machine tool movement.
7. Two ball-roller track integration, the base with a large span of the column design, greatly increasing the column and the base of the contact area, to strengthen the head support design; and the column with high strength overall structure, will enable the machine when The amount of distortion produced is minimized.
8. Spindle cooling cycle, increase the high-speed heat treatment to eliminate, so that prolong the spindle life, effectively overcome the high-speed precision machining surface of the three D-shaped position error. Span design with large precision ball bearings precision grade, high-speed high-precision design, the spindle Sword knife with a unique and stable gas pressure to promote dual role to ensure the rigid life of the spindle (spindle cooling system features optional book)
Belt drive spindle 8000rpm, the lowest noise, minimum vibration, cutting surface optimization.
10 unique tool changer, the original German-style cam Taiwan, the agency uses special materials, precision machining, coupled with a unique heat treatment, the tool change fast, reliable and accurate (no impact on the spindle) and smooth and noise-free.
11. Large-capacity magazine organization, can store 24 knives, and the latest cam-style tool change system, the magazine management using random memory, making the tool exchange quickly, safe and reliable.
12. Electrical box using heat exchangers, can better control the temperature and humidity inside the box, make electrical work stable.
13.Z-axis without counterweight design, increase the Z-axis motor, suitable for high-speed fast moving, effectively enhance the processing of vibration.
14.XH-L716 has a full cover cutting shield, effectively blocking splashes, leakage ensure that the user factory environmental requirements in line with ISO9000 standards.
