Home/Novi strojevi/J-TECH/JT-M1680/M1890A – Vertical Machining Center – CNC Verticals – J-TECH


The novel base is equipped with the composite two-wire and two-hard-roller heavy-duty guide rail.
The built-in pipe can be prevented from scratch and corrosion.
The flexible protective cover and full-rail support made in Taiwan are used.
The high-quality casting is subject to the tempering, vibrating and natural aging treatment to eliminate the internal stress.
Large-torque gearbox spindle (optional).


Technical Highlights of VL850

  1. Rapid positioning: 48m/min. The axis maximum acceleration is 1.0G, thereby reducing the machining and positioning time and effectively increasing the machining efficiency.
  2. Spindle configuration: Straight type 10000rpm spindle, ensuring the stability of high-speed cutting and preventing the power loss of the belt.
  3. Tool-to-tool changing speed: 1.55S Tool storage capacity: 24T
  4. High rigid tapping speed: 5000rpm. Due to rigid tapping and double-speed fallback, the rigid tapping speed is increased effectively.

Structural Highlights of VL850

  1. Base: the base span is increased, thereby effectively dispersing the force and improving the overall stability.
  2. Column: with the large-span herringbone column design and reasonable rib arrangement, the best support rigidity can be provided.
  3. Transmission components: precision screws are used on the three axes and appropriately prestressed. The tail end is pre-tensioned. With the high-precision low-resistance line rail, high-speed and high-precision machining can be realized.

Overall casting
The bearing seat and motor seat are cast with the bed body into a whole, and the saddle and nut seat are cast into a whole.

Ultra-wide base
Use the integrated casting. It has high stability, rigidity and firmness and can provide the stable load supporting capacity. The table will not be suspended. With the strengthening design on each axis, the maximum rigidity and stability can be realized. With the rear-flushing chip removal design and the rear removal type of the base chip removal design, the best removal angle can be provided so that chips can be smoothly discharged into the chip box.

Use the enlarged line rail design. The Class P high-precision and high-rigidity line rails of Taiwan are used on the three axes. In addition, the retainer is added to reduce noise, make the machining accuracy stabler, improve the load bearing capacity and prolong the service life.
