The PROFIMACH© HSVMC–III Series vertical machining centers are designed with a thermal-symmetric bridge type structure to optimize precision and workpiece quality. High accuracy is also enhanced by the constant pre-load high speed spindle.
Walk into any die/mold shop and you’ll find dedicated machines for wet and dry hard milling and graphite milling, three common operations.
Die/mold shops often run dedicated hard milling and EDM machines for these operations because each has special requirements.
Mounting the pressure to minimize costs, while improving machine and spindle utilization will force many machine shops to consider investing in machines with multi-purpose use or so-called all-in-one machines like our HS-VMC Series.
All-in-one vertical machining centers such as our Profimach HS-VMC Series, with graphite and copper milling capability, have wet and dry hard milling capabilities but can also be configured for milling graphite. Using these machines, die/mold shops can lower their costs by reducing downtime, training and maintenance spend. In addition, shops can decrease lead-times and improve machine and spindle usage.
The characteristic twin bridge & column of our HSVMC has been FEM calculated and it’s made of one-piece Meehanite, high quality casting.
This design insures maximum rigidity and performance in High Speed milling and reduces vibrations during heavy cutting operations.
Thermal influences are minimized, due to the short distance between spindle axis and the portal structure.
Thermal analysis of the symmetrical structure proves that this is the optimal
solution for high precision machining of mild products. Full cast iron structure has been stress-relieved giving the machine maximum stability, accuracy and repeatability.
By minimizing the distance between gravity center and the feed drive center, the inertia movement is reduced allowing for faster feed rates and a more precise part.
High quality special casting FCD45 is used on saddle and ram, to get the fastest and most precise feed response on Z axis movements.
Roller type Guideways
Japan/Taiwan high rigidity and heavy-duty roller type linear motion guideways on 3 axis, provide low starting inertia, low friction and high acceleration rates. Servo motors and drives are optimized to ensure immediate &precise machine response necessary in high speed cutting, positioning and contouring.
User-Friendly & Ergonomic guarding design
The design of the guards allows for optimum viewing of the part being machined. Totally enclosed guarding includes roof top/side to keep all the chips, water and noise inside the machine and to have clean, quiet and comfortable environment also around the machine. The machine has been carefully designed to provide a reduction of overall floor space dimensions.
Automatic Tool Changer
Disk Type 16 station automatic tool changer installed as standard.
The size and load capacity of the table allow the setting up and cutting of larger workpieces of various shapes.

The health and welfare of toolmakers that use graphite to make electrodes for use in the electrical discharge machining of molds should be a high priority for management. In addition to the health issues for the workers, the very expensive machinery, such as the EDM machines and milling machines, must be protected from the damaging effects of graphite dust. EDM and injection molding are inseparably linked in the manufacturing process of plastic products.
Anyone who has worked with graphite in the manufacturing of EDM electrodes is keenly aware of the need for proper dust removal during the machining process.
Graphite dust is highly conductive and has been responsible for the damage of many expensive tools and machines. Glass scales can give false measurements due to the settling of dust. Electronic equipment can be short-circuited by the dust as well. The grimy nature of graphite makes it especially annoying if it accumulates on work-benches and desks.
It is in the best interest of everyone to make every effort of maintain a clean and pleasant atmosphere in a mold making or EDM shop. The toolmakers will be happier, the work will be better and the machinery will perform as it should. It is also very impressive to visitors to see a clean, dust-free shop.
Powerful Controller with M3 Bus Protocol
NTEC 21MA controller comes with serial bus Mechatrolink-III connection motion control, improves machining performance by decreasing interpolation time and increasing surface’s smoothness. Serial bus communication control also improves traditional pulse delay of differentiate transfer time between axis, provides a simpler system and easier to install and setup.
High Speed, High Precision, High Quality
SYNTEC 21MA controller is equipped with 2500blocks/sec. computational ability, 2000 block look ahead function and High Speed - High precision feature, such as SPA, HPCC, surface smoother, quick parameter setup, high speed tapping, multiple spindles synchronize motion tapping etc. SYNTEC 21MA is definitively the best solution for high efficiency and high precision mold machining.
High-Speed, High-Precision Machining (HSHP) function included
The HSHP function in the dedicated mold making controller can process 2500 blocks/sec (program lines) and look-ahead 2000 blocks each second.
These enable smooth motion and enhance surface quality. To advance the precision, the included HSHP function also controls the corner and arc feed-rate efficiently.
Smooth Precision Advanced (SPA) Function included
Due to limitation of machine condition, servo mismatch can be found even the servo loop gain has been optimized. This error causes dimensional shrinkage especially in high-speed machining. SPA feature is designed to overcome this issue.
Path Smoothing Feature included
By trimming the rough program path generated by CAD/CAM software with a tolerance, the desired smooth and fine path is estimated by Path Smoothing function. This improves the surface finish, machining efficiency and stability of machine tool.
High Precision Contour Control (HPCC) function included
The tool path generated by CAD/CAM software is generally discontinuous,
and it causes negative effects on machining operations. The problems will be more serious because of larger CAD/CAM tolerance. HPCC function fits the discontinuous blocks into a smooth-curve path, and this will enhance the machining precision and reduce the mechanical shock.
