Machine main features:
1.XH-715B bed and other key components are used Mihanna (bake) casting. Casting material grades
FC-30. Casting structure using one-piece molding technology, box structure, its advantages: high stability, small deformation, can effectively inhibit vibration, greatly extending the service life of machine tools. Coupled with the unique structure of the corresponding components of precision machining, heavy cutting outstanding performance. The driver The bed strictly according to the ISO static precision inspection standard organization each production process strict checks the excellence.The factory machine conforms to the national JB / T8771.2-1998 standard
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 has self-lubricating, so the surface hardness after quenching HRC48-52, used in the metal surface friction caused by thermal shock on the workpiece, such as the machine tool Z-axis feed, countertops and so on.
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. Cooling the circulating oil, adequate circulation with efficient cooling machine, the effective control of the spindle temperature, spindle speed constant security operation.
4. X / Y axes are linear slide, with high rigidity, low noise, low friction characteristics, can do rapid displacement and get the best round precision, Z-axis with three-rail design can effectively improve the stability of the processing Sex, with the balance of weight to overcome due to sudden power off the Z axis caused by the workpiece, the tool loss.
5. All three axes are precision ball screw preloaded with C3 double nuts. With pre-tensioned design of both ends support blocks, transmission backlash can be eliminated and errors caused by temperature rise can be compensated in advance to ensure the positioning accuracy.
6. The Division of the machine produced by Renishaw laser measurement test, three-axis trip for the machine parts using 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.
7. Circular measurement test, the use of circular analyzer / Renishaw, correct roundness and machine geometry accuracy, to test to ensure the accuracy of the machine tool movement.
8. Two rail integrated base with a large span of the column design, greatly increasing the column and the base of the contact area, to enhance the head support design; and column with high-strength hard-rail structure, the machine will be able to use the resulting distortion Minimize volume.
9. Spindle cooling cycle, increase high-speed processing heat to eliminate, so that the spindle life to effectively overcome the high-speed precision machining surface of the three D-shaped position error. Span design with large precision ball bearing precision grade, high-speed high-precision design, 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 is an optional feature)
10. Belt drive spindle 8000, the lowest noise, minimum vibration, cutting surface optimization.
11. Unique tool changer, using the original German-style cam in 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 noiseless.
12. 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.
13. Electrical box using heat exchanger, can better isolate the dust, reduce the temperature inside the box.
14.XH-715B has a full cover cutting protective cover, optional According to the customer a number of safety requirements, such as electrical control cabinet safety devices, safety doors, operating the door of the special enhanced design, both sides of the door sliding rail design to ensure that Machinery and personnel safety, in line with ISO9000 standards.
