LCV-760/LCH-500.

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.

Swing Type APC.
 

The LCH / MH Series machines have a standard 2 pallet swing type changer system. The LCV series machines have one piece swing table. The load position at the front of the machine allows easy loading and unloading of work pieces. The pallets are positioned and clamped to the table with four precision taper cones to ensure accuracy and rigidity. During the pallet changing cycle compressed air is blown through the cones to clean the clamping surfaces, removing chips and coolant. This air assures pallet location accuracy and long componet life.

 
Standard 4th Axis Rotary Table (LCH and MH series).
 

The contouring rotary tables with a minimum indexing increment of 0.001 offer simultaneous machining functions for complex profiled workpieces. Extra large preloaded thrust bearings insure smooth and accurate table rotation. Four clamping cones insure accurate and repeatable pallet location along with excellent rigidity.

One-Piece Swing Table.
 

The one piece swing table makes the LCV Series machines flexible machining centers with dual set-up capability. The operator can load & unload parts on one side while the machine works on the other side. The tables are positioned and clamped with four precision taper cones to ensure accuracy and rigidity.

 

The table indexing system is fast and smooth:
LCV-500 -> 4sec.
LCV-760 -> 14sec.
LCV-1100 -> 12sec.

 
Cast Iron Construction.
 

LEADWELL uses 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 rigid T-shaped, single-casting base construction provieds excellent rigidity and avoids overhang of the stationary table. The traveling coolumn design reduces the required floor space and provides excellent accessibility to the machine table. Heavy duty linear guide ways insure accurate positioning and rapid travel for all axes. 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.

Directly Coupled Servo motors.
 

The LCV-Series servo motors are connected to the ball screws with rigid shaft couplings. These couplings ensure that even under severe loading from sharp machining, precise interpolation is achieved. This design is superior to both belt driven and flexible shaft coupling designs (with pretension).

 
Chip Removal.
 

LEADWELL's simple and efficient design uses chip augers 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.

Cartridge Type Spindle.
 

The heavy-duty spindle utilizes FAG, NSK or SKF bearings to allow heavy cutting. Overszied 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.

 
Side-Mounted Tooling System.
 

The tool magazine is isolated from the machining area. An automatic door keeps Chips from contaminating the tools' tapered shanks. Having the next tool ready near the spindle during current tool machining, drastically reduces tool change time.

Automatic Tool Changing System (Opt.).
 

The high-speed ATC activates a high-pressure air blast to clean the spindle taper and the ATC tool pot to ensure accurate tool holding. Tools are automatically returned to their original location, eliminating tool interference from oversized tools in the magazine.
