VMC-2210 Vertical Machining Center

Mechanical properties

• Aigma's three-axis guideways feature a hardened design, offering heavy-duty cutting capabilities and high rigidity. They absorb most of the cutting reaction forces generated during cutting while maintaining sensitivity comparable to linear guideways. To meet the diverse processing needs of today's customers, we conduct practical processing tests on some difficult-to-machine materials. Our aim is to better meet the needs of customers at all levels, hoping to create a win-win situation for both supply and demand.
• Overall high rigidity structure
  The three-axis track adopts a hardened rail design. The head, body, saddle, base, worktable 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.

High-horsepower spindles suitable for heavy cutting The sleeve-type spindle design provides a 4,000/6,000 rpm geared spindle, and the short nose spindle bearing is effectively supported by the bushing and head casting, which can greatly improve the spindle rigidity. With the option of a high-horsepower spindle motor, the maximum metal cutting rate can be achieved. With the spindle cooling system, the temperature rise of the bearing can be reduced and the spindle life can be extended.	Honeycomb column design The VMC-199/229's uprights feature a hexagonal honeycomb structure design, which strengthens the uprights themselves and reduces variations that occur during machine operation and movement.
Optimal spindle rigidity The sleeve-type spindle design provides belt-driven spindles at 6,000/8,000/10,000 rpm, and the short nose spindle bearing is effectively supported by the bushing and head casting, which greatly improves the spindle rigidity. Combined with the extremely rigid head, it can absorb most of the vibration and prevent poor machining surface due to tool vibration.	Gear head The two-stage gear design allows the spindle to run smoothly. The transmission gears are made of Japanese chromium-molybdenum alloy steel that has been hardened and precision ground, ensuring quiet and smooth spindle operation. The spindle adopts a floating tool-changing design to extend the life of the spindle bearings.
Excellent base design The VMC-229 features a six-rail integrated base structure design, which effectively supports the saddle and worktable, allowing the workpiece to be fully utilized within its effective machining stroke, and also provides stability for future customer use.	belt head The robust head design, with the optimal golden ratio between the contact surface between the head and the column rail and the distance between the two rails, effectively showcases the machine's rigidity.
Double stop design To prevent the motor housing and bearing housing from shifting, all three axes employ a double stop design to ensure machine tool accuracy.	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.
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.	X-axis spiral chip conveyor It facilitates the removal and collection of metal filings, keeping the working area of ​​the machine clean.
Volumetric oil distributor It adopts the Japanese SHOWA volumetric oil distributor, combined with aluminum alloy oil pipes, to evenly distribute the oil injection points, so that the oil injection volume at the far and near ends is uniform, preventing uneven lubrication of the sliding surface.	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.	Excellent triaxial support design All three axes use C3-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.
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.
Fluorescent lamp (special accessory) It must be used with a fully enclosed cutting guard, installed on the upper right and front left of the guard, providing a bright lighting design, a thoughtful design considering the operator's environment.	Robust box-type worktable design The unique double-layer box-type worktable design reduces deformation during heat treatment, increases the load-bearing capacity of the worktable, and enhances the selectivity of the work.
Box-type stepped treads (special accessory) It can be used with box-type ladders to facilitate operators in getting on and off workpieces and in operation, which is in line with the current humanized design that prioritizes customer satisfaction and operator experience.
