Machine main features:
1.HV-1250A bed and other key components are used Mihanna (bake) casting. 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 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 Three-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. Unique bed column up and down the structure, column rail width up to 355mm, high precision and stability, smooth finish 1.6, heavy cutting ability prominent (for example: straight shank φ32 processing depth 25mm).
3. Box base with sliding column design, greatly increasing the column and the base of the contact area, to enhance the head milling head design, the machine will be able to minimize the amount of distortion generated.
4. Y-axis with steel rails, X, Y rails for high rigidity hard track, and after induction hardening (including table) and then precision grinding, and paste with a special synthetic resin (TURCITE) Careful scraping, long Years to maintain accuracy
5. Elevator column built-in 8-section gear box drive in the horizontal spindle, and the teeth have been driven to the milling head spindle, gear change are oil bath lubrication, and the gear chrome molybdenum alloy steel by heat treatment grinding. Minimum noise, minimum Vibration, cutting surface optimization
6. Spindle with precision large ball bearings, and has focused on lubrication devices, and the spindle can be a long time in high-speed operation to maintain the temperature rise.
7. Three-axis are used T-screw, X-axis preload support at both ends of the seat design, to eliminate transmission backlash and pre-compensation temperature error caused by errors to ensure positioning accuracy.
8. Mechanical handwheel, handle are concentrated in the front of the easy-to-use position, and with removable electronic control box to ensure the operator's safety and convenience.
