VMC-116 Vertical Machining Center

Mechanical properties

• Overall high rigidity structure
  
  1. The three-axis track adopts a hardened rail design. The head, body, saddle, base, table and column are all made of high-grade Meehanite cast iron and have undergone stress relief treatment, resulting in stable mechanical precision and excellent rigidity.
  2. All slide rails are hardened and precision ground to ensure accuracy.
  3. The counterweight is equipped with dual guide rails to ensure that the counterweight does not wobble when the Z-axis moves rapidly, thus ensuring the precision of the machined surface.
  4. The spindle head is reinforced with ribs, and the contact length between the spindle head and the column is appropriately proportioned, providing stable support for the spindle.
• shorten the distance between the workpiece and the operator
  
  1. The design takes into account the ease and stability of the operator's loading and unloading work, and adopts a front concave protective cover design, which is ergonomically designed.
  2. The Y-axis servo motor is positioned at the rear of the machine, which reduces the distance between the operator and the table, making operation more convenient.

High-speed direct-drive spindle The spindle features a large span design and is equipped with precision-grade angular contact ball bearings, resulting in a high-speed and high-precision design. Direct-drive spindle 10,000/12,000/15,000 rpm, lowest noise, minimal vibration, and optimized cutting surface.	base The VMC-95/115 base features an integrated four-rail heavy-duty design, capable of withstanding heavy loads while maintaining high precision.
Long nose tip belt head spindle It offers three different spindle designs, combined with a modular head design, and features belt-driven spindles at 6,000/8,000/10,000 rpm. The dynamically balanced pulleys and high-tension toothed belt drive prevent slippage and ensure smooth operation at high speeds, while significantly reducing transmission noise and heat generation.	Short nose tip main axis The head column is lengthened and the joint surface is optimized to 1:1 to improve cutting rigidity. The spindle, with its large upper and lower support span and high rigidity design, combined with the head casting, can offset most cutting vibrations, extend spindle life, and reduce cutting tool costs. Combined with an interchangeable tool arm magazine, tool change time is short. The floating tool retraction mechanism eliminates the impact force on the spindle bearing during tool changes, improving spindle durability and rigidity.
PMC Notary Office Laser Measurement and Testing Agma commissioned PMC to conduct 100% inspection of the three-axis travel portion of the machine tool. The inspection standard is VDI 3441 3, which involves six full-stroke inspections in both directions to ensure the accuracy of the machine tool and the impartiality of the inspection.	Volumetric oil distributor A volumetric oil distributor is used in conjunction with aluminum alloy oil pipes to evenly distribute the oil injection points, ensuring uniform oil injection volume at both the far and near ends and preventing uneven lubrication of the sliding surfaces.
Circular Measurement Inspection A circularity measuring instrument/Renishaw is used to calibrate the roundness and geometric accuracy of the machine tool, thereby ensuring the motion accuracy of the machine tool.	Central lubrication system The machine adopts a central lubrication system with depressurized oil injection, and the oil injection time is controlled by PLC program, which makes it easy to check the oil gauge and add oil, ensuring the machine's accuracy and lifespan.
Shovel work Japanese-style scraping technology, combined with unique *-shaped scraping and Z-shaped oil grooves, creates a uniform oil film on the sliding surface, eliminating floating phenomena during rapid movement and stickiness during the start of cutting feed.	Shovel resistance test After the precise and unique shaving operation, a torque meter is used to scientifically test the friction coefficient of the slide rail contact surface to ensure that the shaving adhesion rate meets or exceeds the qualified standard. The machine is then assembled under the most natural conditions to achieve smooth feeding and increase the accuracy and service life of the machine.
Spindle cooler High-efficiency spindle coolers can effectively remove the oil that generates heat during high-speed spindle operation, ensuring the accuracy and lifespan of the spindle during high-speed operation.	Well-organized electrical The wiring inside the electrical box is neat and the design complies with safety regulations. Each relay has a clear serial number, and the modular and systematic design facilitates maintenance.
Anti-collision and braking design When overtravel occurs, it prevents direct collision between the flange, motor housing, and bearing housing, and also prevents displacement of the motor housing and bearing housing. Excellent triaxial support design All three axes use C2-grade double-nut preloaded precision ball screws, combined with the pre-tension design of the support seats at both ends, which can eliminate transmission backlash and pre-compensate for errors caused by temperature rise, ensuring positioning accuracy and repeatability.
