HPC450 high-speed vertical machining center is a high-tech product of mechanical and electrical integration, developed by our company on the basis of absorbing advanced technology domestically and abroad. The product can perfectly achieve high-speed processing through the breakthrough of speed and precision combination technology, and it can complete the milling, drilling, tapping and surface machining.  VPC500H is highly automatic and can be widely used in electronics, instrumentation, automobiles, motorcycles, military, medical equipment and other fields. Its main features are as follows:


1 Good Structural Rigidity
1.1 Adopt high-strength cast iron materials and resin sand casting technology for machine tool base castings (including bed, column, bed saddle, spindle box, work table, et). It has high mechanical and thermal stability.
1.2 The body of the machine tool adopts bed structure, and the base adopts the overall inverted box type structure. A considerable number of triangular bars are arranged on the inner wall of the, improving the unit mass stiffness of the castings, and producing good rigidity.
1.3 The columns of the machine tool adopt double column closed frame structure, with longitudinal and horizontal ring bar arranged in the cavity, so that the columns have a high anti-bending rigidity. Also the use of heavy-duty roller guide greatly improves the spindle box’s movement accuracy and contact rigidity.
1.4 The form of the machine tool is modified from T-slot to screw hole for the convenience of fixture, and the rigidity and stability of the worktable are greatly improved. This also improves the deformation due to T-slot tooling tension.


2 The Main Drive
2.1 The machine adopts high strength synchronous belt for the drive from the digital AC spindle servo motor to the spindle, which can drive with good rigidity and high accuracy. 
2.2 The spindle components are of high precision and high rigidity; the spindle bearings are import brand.
2.3 Adopt butterfly spring to achieve the tool tension and pneumatic hydraulic cylinder loosing tool. 
2.4 Nitrogen balance mechanism can be equipped with vertical movement, reducing the vertical motor load and improving the rapid response performance.
2.5 The spindle unit is of standard BT40 specification, with ring spray function and air curtain protection device, completely avoiding the infiltration of the cutting fluid and dust.


3 Feed Drive
3.1 The feed drive system adopts direct link between all-digital AC servo motor and ball screw by coupling to reduce the transmission stages and improve response speed of the movement. The couplings are imported, with high strength and small inertia, to reduce the rotation inertia. 
3.2 All three shafts are 4016 import C3 level double nut ball screw. The ball screw nut is pre-tightened to reduce the clearance between the nut and the raceway.
3.3 All the three feed shafts adopt high-precision laser interferometer after assembly which can accurately measure the transmission link error and make compensation for the screw pitch and clearance in the system so that the shafts move their positions more accurately to ensure the accuracy of positioning and repeated positioning.
3.4 All the three guide rails adopt 45 # import heavy-duty roller linear guide, with V3 level pre-load. They can bear high load and have stable accuracy.


4 Lubrication System
4.1 The lubrication system is equipped with a centralized lubrication device, which regularly and quantitatively lubricates the guide rail and ball screw. 
4.2 The lubrication flow and lubrication time has been adjusted before leaving factory, so the user does not need to change them by himself.
4.3 The automatic and centralized lubrication device has alarm system, which works when the oil level is lower than the set value. At this time, the user needs to add lubricants timely.


5 Machine Cooling, Chip Removal
5.1 The work piece and the machine tool are cooled by high pressure spray coolant. Large flow of coolant is sprayed to cool the tool and the work piece during machining.
5.2 Optionally, the machine can be equipped with automatic chip removal device, so that chip removal is more convenient.


6 Pneumatic System
6.1 The FR&L are standard configuration to filter the impurities and moisture in order to prevent damage and corrosion by the impurities.
6.2 The functions of the pneumatic system are controlled by PLC program through solenoid valve.
6.3 A hand-held dust gun is provided with the machine for the cleaning of cutting chips.


7 Machine Protection
7.1 Adopt a special guide rail protection hood or other effective protection method in the machining area.
7.2 The machine is surrounded by a closed shield, with beautiful appearance, clean and tidy.
7.3 The guide rail protection hood guarantees that the cooling liquid and iron chips will be safely and adequately recycled.


8 Machine Tool Library
8.1 The machine adopts advanced arm locking library with 24 tools. The tool change is completed by mechanical arm, fast and reliable.


9 Control System
9.1 The machine is configured with FANUC-0I-MF system and its supporting drive, which has reliable performance and full-function, and is easy to maintain.
9.2 The machine has a handheld operating unit, with user-friendly operation.
9.3 The main electrical components of the machine are Siemens brand, improving the reliability of electrical control.
9.4 The machine is configured with a standard 8.4-inch color display, with beautiful interface, simple and convenient operation.


10 Indexing Turntable
10.1 The machine tool adopts the indexing turntable to achieve the indexing (B axis) movement. The guide rail adopts Taiwan heavy-duty roller guide, with good rigidity and movement precision.
10.2 The indexing turntable achieves the worktable rotation by an AC servo motor through the gear pair and a pair of worm gear pair.
10.3 The clamping and release of the indexing turntable are achieved by oil cylinder.
10.4 The rotary position accuracy of the indexing turntable is guaranteed by the high precision end gear plate. The minimum graduation unit of the indexing turntable is 1 °.
