The VTplus series of compact chuckers incorporates technical features that should enable the user to maximize profit potential through a high rate of performance that will increase productivity.
Friendly Control System
The machine utilizes the FANUC 0i series controller together with the new series motors, as this prove combination ensures high performance and reliability.
Expandability and Automation
The design of the VTplus machines has an emphasis on automation. The physical size of the machines is ideal for cellular manufacturing systems, where it can be coupled to gantry type loading devices, barfeed equipment or robotics. Coupling a machine with any of these items gives a low cost automation process, beneficial to the intended purpose of the machine to maximize profit with performance.
- Machining Accuracy
- On tests, these machines have proven to be capable of high positional accuracy and have achieved outstanding surface finsih performance.
- Suitable high machining quality required such as motor and hydraulic parts.
- Material:Brass
- Insert:Diamond (nose R 1.2)
- Surface speed: 300m (984ft) / min
- Cutting depth:0.02mm (0.000787")
- Feed rate: 0.02 mm (0.000787") / rev
- Spindle Torque Output Diagram
- High Speed Tool Changing
- Axial Drives
- To reduce backlash, friction and vibration, drive belts and gears have been eliminated from feed drive mechanisms, by direct coupling of servo motors to the ballscrews.
- Rapid traverse rates of up to 24 m /min are standard.
- Rigidity and Reliability
- Compact Design
- Continuous Machining Accuracy
- Offset tool holder, designed to reduce spindle height, makes cutting more stable.
- The headstock is designed to minimize the effects of thermal expansion. In tests, a high Cp value (Capability of Precision, the higher the value obtained, the better accuracy repeatability displayed) of 1.41 at 15 m tolerance if obtained on VTplus-15/20.
- This remarkable achievement even reaches grade A--the highest level (Cp value over 1.33), which shows the accuracy and stability, of the VTplus machines.
Cutting condition on VTplus-15
The directly driven spindle unit uses the powerful FANUCP series motors with their wide range of high torque output and fast acceleration times to optimum speeds.
Fast tool changing is an essential requirement to reducing idle time, and the random bi-directional turret fitted to the VTplus sreries has a station to station time of 0.3 sec. A camlock mechorism aids heavy hogging while also ensccing excellent tool change repeatability.
The VTplus series has been designed using the latest computer analysis technology to simulate stresses in the machine structures so that the design can provide the optimum rigidity and cutting stability.
The simple compact design occupies minimal floor space, 2.15 x 1.56 m for VTplus-15/20.To assist in tailoring the machine to fit into existing shop floor layouts, the swarf conveyor can be located at either the rear or the right hand side of the machine bed.
