Brand new highspeed bridge type milling machine on the show
One of the demonstration machines is the bridge type milling machine with CNC control Heidenhain, model SKYMASTER VF1615A (High Speed). This brand new high-speed portal milling machine with extensive accessories is available at a special introductory price. Many of the components installed in the machine are from a few manufacturers such as Heidenhain, Japan Nsk, Rexroth Germany, IBAG, Igus, KTR, Mecano and Schneider. This bridge type milling machine designed for production using materials where high speeds and feed rates are required. Of course, it can also handle many other things extremely effectively. Highest precision and high speed in machining are the essential criteria of this model. The distance between the two machine stands is 1500 mm. The distance from spindle center to table is adjustable from 225 mm to 925 mm. The table size is 1800 x 1300 mm and the table load is up to 4000 kg possible. A powerful spindle motor with 25/33 kW and a maximum spindle speed of 24000 rpm enable high-speed machining. The tool changer can take tools in the standard version 20.
VL700A Machine technical characteristic
All cast parts have gone through multiple software analysis, and a stress ageing treatment to release residual stress (two thermal and one vibration ageing treatment), the great rigidity from the casting part ensures the machine’s good accuracy and stableness.
The 11/15kw spindle electric servo motor has better power and torque compare to similar product from other brands. It provides great cutting rigidity.
The spindle equipped with the unclamping cylinder, decrease shocks and impacts act on the spindle, ensure the accuracy as long as possible.
Shoulder carrying type ATC with small deformation and short tool change time. Fully closed tool magazine cover protect the ATC system from metal chips damage.
The Z axis use a extra powerful electric motor, eliminate the balance weight and extra electric current, it can increase the reaction speed of all three axes and accuracy when change direction.
All axes use high rigidity P grade ball type guide way. This type of linear guide way has good heavy loading performance, low wear, high accuracy also can bear load from every direction as long as it acts on the cross section.
The machine was fully covered by the protection shield. The protection shield was designed according to human body geometry, safe, visually pleasing and easy to operate.
The lubrication and pneumatic system are from Japanese brand SHOWA and SMC. Those two systems were located at the left hand side, back of the machine, easy for observation and maintenance.
The machine equipped with chain chip conveyor, clean chips efficiently and safely apothekeschweizer.de. There is a CE protection shield at the chip exit point with emergency button, protect the operator from danger.
VM3018A is a modernized gantry type machining center equipped with automatic tool change device and CNC triaxial linkage control system. Suitable for medium lot sizing production of machining different types of surfaces, holes and complex shapes, especially for large and medium-sized porous body parts. Save tooling and fixture, shorten the production cycle, improve the machining accuracy.
It is the perfect equipment for mechanical processing and technical transformation to use in the national defense industry, automobile manufacturing, light industry, textile machinery, mould industry and machine tool industry.
On the recent years, SKY MASTER-KRAFT has given rise to a new power on the European mold field. We gained a lot of great reputation among these years especially for our VM18 series, most of our end-user are using this series for making mold of BMW, Mercedes-Benz and so on.
This product has the following characteristics
The spindle has four specially made NSK supporting bearing, increased the rigidity of the spindle. It also has an oil cooler, provides forced cycle cooling.
The spindle is driven by digit servo motor and directly connect with imported gear box which improve the transmission efficiency and machining accuracy ,as well as energy saving.
The spindle uses a synchronous belt for decelerating. The belt directly connected to the high rigidity ball screw pair. Y and Z axis both use servo motor directly connected to the high rigidity ball screw pair. The support of the ball screw uses a fix one side extends other side type of design, makes the ball screw has pre-extended effect. This type of design increased transmission rigidity, positioning accuracy, repeatable positioning accuracy and stability, also increased stability under heat.
All three axes’ supporting guide way uses high accuracy heavy loading roller type linear guide way. Low friction, high rigidity, high positioning accuracy, short reaction time.
ATC: whole system was imported from Taiwan, unfailing performance with short tool change time.
The machine equipped with protection shield. The protection shield was designed according to ergonomics, provide a comfortable operating experience.
The whole machine use high quality casting iron. Two times aging processes make the composite stable, can keep the accuracy high for longer time.
A liquid nitrogen balance device was used for spindle’s weight balance. Simply structured, stable, make sure the accuracy is at its best at all time.
Equipped with two coil type chip conveyer and a additional chain chip conveyer. Safe, environmental friendly, convenient and efficient.Sincerelywelcome all customers and friends to visit SKY MASTER-KRAFT.
