2. The ball screw, linear guide rail and spindle of the whole machine are imported from Taiwan Province Province;
3. The bearings of the whole machine are NSK bearings made in Japan;
4. The spindle adopts Taiwan Province BT40/50 or Italian HSD high-speed motorized spindle, and the maximum idle speed of the spindle reaches 12000RPM, which ensures the optimization standard of machining efficiency; BT40/50 taper hole has good shaft head rigidity, easier tool change and sufficient clamping force.
The spindle, wire rail and ball screw are all equipped with dust-proof blowing devices, which can prevent foam dust from entering the spindle, wire rail and spindle and causing money loss. Both the track and the screw are equipped with automatic lubrication devices, which can effectively discharge foam ash and avoid damage.
7. The X-axis should be driven by a twin screw, which is stable in balance and can avoid unilateral imbalance caused by a single screw.
8. The whole machine adopts high rigidity structure, and after aging annealing treatment, the processing range is large.
◆ The Z-axis stroke can be increased to 1.5m, and the processing format is large, which is suitable for processing large and super-thick materials. ?
◆ Intelligent handling of cross-border protection function can prevent mechanical collision caused by excessive handling of design documents. ?
Diversified control can control machining speed, idling speed and cutting speed respectively, which greatly improves the quality and machining efficiency of processed products. ?

TIPs EPC
Lost foam casting (also known as full mold casting) is a new casting method, which combines paraffin or foam models similar in size and shape to the castings into model balls, brushes them with refractory coatings and dries them, then embeds them in dry quartz sand for vibration molding, and then pours them under negative pressure, so that the models are gasified, and the liquid metal occupies the model position, and then solidifies and cools them to form the castings.

Compared with traditional sand casting, EPC has the following advantages?
1、? Lost foam casting does not need parting and lower core, and is especially suitable for box castings, shell castings and barrel castings with complex geometry and difficult to complete by traditional casting. ?
2、? The dry sand mold for EPC can be reused, with less industrial waste and obviously reduced cost.
3、? There is no flash burr in EPC, and the cleaning time can be reduced by more than 80%.
Lost foam casting cancels the molding process, and people with a certain educational level can become skilled workers after short-term training, so it is especially suitable for areas and enterprises lacking technical strength. ?
4、? Lost foam casting is suitable for group casting, and it is easy to remove sand by burying dry sand. Some castings can be treated with waste heat according to their uses. ?
5、? Lost foam casting is not only suitable for small and medium-sized parts, but also suitable for large castings, such as machine tool bed, large diameter pipe fittings, large cold stamping parts, large mining equipment accessories and so on. Because of the short production cycle, low cost and short production cycle, the model is particularly well received.
Lost foam machining center is a numerical control equipment specially used for foam machining of automobile stamping die, which belongs to light cutting numerical control machine tool. The lost foam machining center of Nanjing Wangdian CNC production is a kind of CNC equipment specializing in full mold machining, which is characterized by fast machining speed and stable operation.
