T-8M Series.

LEADWELL's mission is to constantly search for excellence and gain respect in the industry. Using our 25 years of experience, the entire staff at LEADWELL pledges to bring innovation, quality assurance, worldclass after sales service, and environmentally friendly machine tools to the worldwide marketplace.

 

We strive to win the respect of both our customers and world wide competitors alike.

Headstock.
 

Heavy duty thermally symmetrical headstock design has heat dissipating fins to minimize thermak distortion during long machining clcles. All critical components are machined in a temperature controlled environment and assembled in a clean-room.
Cartridge style spindle provides quick and easy replacement

 
Directly Coupled Servo Motors.

The T-8 series servo motors are connected directly 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 belt driven and flexible shaft coupling designs.

T-8 servo motors have 1,000,000 pulse encoders for high accuracy of linear axes.
Motors are the same between X & Z axes which reduces spare part requirements.

Tailstock.
 

Heavy duty tailstock with large diameter quill and precision Morse taper provide outstanding rigidity.

Quill adjustment is hydraulic.

 
Sub-spindle.
 

The sub-spindle replaces the standard tailstock on T-8S and T-8SM turning centers. A position encoder is attached to the sub-spindle so the sub-spindle can then be synchronized with the mainspindle. Special software allows the work piece to be transferred from the main spindle to the sub-spindle at any speed for secondary machining operations, This eliminates the need for operatorintervention.

Allows machining of both ends of parts.
Works great with bar feed option and parts catcher for unmanned operation

Double-Nut Ball screw.
 

LEADWELL uses only premium qualitypreloaded double-nut ball screws. Each ball screw is accurately aligned parallel to the linear guide ways and anchored at both end. They are then pre-tensioned to improve machine stiffness and reduce thermal growth. With this design they exceed customer requirements for accuracy and maximum life.

Rotational torque variations are measured to guarantee a non-binding, highly accurate, and longrunning components.

 
The Roller Type Linear Guide way.
 

T-8(M)/T-8XL(M) equip with roller type linear guide way can provide higher rigidity and make the movement more smooth and stability, especially for the request of high accuracy and heavy load.

Cartridge Type spindle.
 

The heavy-duty spindle utilizes FAG or NSK ABEC-7 bearings to support heavy cutting.

Wide bearing spacing for high rigidity
Special heat treatment for critical parts
Highly accurate draw tube mechanism
Precision labyrinth seal
Large diameter quill for high rigidity

Optimum spacing of front bearings to spindle nose for highest rigidity
All of which produces better part finish in less time.

 
Parts catcher.
 

The unique LEADWELL parts catcher design works well with the bar feeder option to improve productivity. Parts are transferred outside the operator door, which eliminates the need to stop the machine to unload finished parts

This option can be easily added to any T-8 series machine.
Used with the Bar Feeder option, the T-8 becomes an unmanned machine.

Servo tailstock.
 

Rigid tailstock driven by a servo motor provides outstanding stability.

 
Tool setter.
 

LEADWELL's tool setter option measures both radial and axial tools. It uses macro programming to automatically define and update tool offsets.
Reduces setup time. The tool setter option can also check gor broken tools.
