Features:

The MV-Series servo motors are connected to the ball screws with rigid shaft couplings. These couplings ensure that even under severe loading from sharp corner machining, precise interpolation is achieved. This design is superior to both and flexible shaft coupling designs.
 
Simple and efficient design uses chip augers on both sides of the machine and provides high volume coolant to wash the chips from the work area. The augers move the chips into the disposal container, which eliminates the need for an operator to manually remove chips. This system eliminates operation intervention and reduces non-cutting time.
 
We use only premium quality preloaded double-nut ball screws from THK, IBU STAR and HIWIN. On the MV-Series machines each ball screw is accurately aligned parallel to the guide ways and anchored at both ends. They are then pre-tensioned to improve machine stiffness. The rotational torque variation is inspected to guarantee a non-binding, highly accurate, and long running component. With this design the MV-Series can exceed customer requirements for accuracy and maximum life.
 
The operator panel swivels for better operator convenience.
 
We use only top quality well-ribbed castings. Finite Element Analysis (FEA) is used on each new casting to determine the size and location of all internal ribs ensuring high torsional stiffness and minimum vibration. The cast iron base column, saddle, headstock, & tables have over 10 times the dampening capacity of those made from steel resulting in superior cutting performance.

We use STAR and HIWIN linear guide ways that feature zero clearance and fully-loaded carrying capacity in all directions. The ways consume less power and requires no adjustments. They linear guide ways out perform all other types of ways used today. Additionally, each way is automatically lubricated independently to increase life.
 
The heavy-duty spindle utilizes FAG or NSK ABEC-7 bearings to allow heavy cutting. Oversized disk springs used to hold the tool in the spindle are tested for long life. The high retention force of the springs reduce tool movement, improve tool life, allow heavier cutting, reduce chatter, & create a better part finish. This spindle is prepared to easily add the CTS option.
 
The encoder is directly attached to the high-performance spindle motor. The spindle is then synchronized with the Z-axis motion. This synchronization eliminates the need for expensive floating tap holders and prevents thread distortion and thread pullout.
 
We use a stringent ball bar test that checks not only linear accuracy but also machine geometry. This test insures that each machine meets the three-dimensional squareness and accuracy requirements.
 
High Productivity Options
 
4th Axis Rotary Table Option: This 4th axis rotary table option boosts productivity by allowing more machining with a single set-up. It also can turn the V-Series machine into a 4 Axis contouring machine which adds versatility.
 
This unique programmable coolant nozzle option provides precise coolant control. It allows the NC program to change the coolant direction during the machining cycle. The nozzle can be programmed for tool lengths from 60mm (2.4") to 250mm (10"). This option eliminates operator adjustment causing unnecessary downtime.
 
Our tool probe option measures both tool length and tool diameter. It uses macro programming to automatically define and update tool offsets. This option will ease setup, and check for broken tools.
 
The optional CTS includes an auxiliary high-pressure pump, which supplies high pressure coolant to the cutting edge. CTS improves tool life, allows both deep hole drilling and blind pocket milling. It also allows higher speeds, which reduces cycle time. This option can be easily added to any MV-Series machine.
 
The cutting torque is maximized by combining the German ZF-2-speed gear box with the oil cooled main spindle. The gearbox has its own separate lubrication system.
 
The two speed spindle option advantages are:
 
"Over 95% efficiency
 
"Quiet gears
 
"Heat is not transmitted to the main spindle
 
"Gear vibration is not transmitted to the main spindle
 
"Minimum backlash
