LEADWELL CNC MACHINE - MH SERIES



















CAST IRON CONSTRUCTION
LEADWWELL uses only top quality well-ribbed casting. 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 travel column design reduces the required floor space and provides excellent accessibility to the machine table. Heavy duty linear guide ways ensure accurate positioning and rapid travel for all axes. The cast iron base coloumn. saddle, headstock and table have over 10 times the dampening capacity of those from steel resulting in superior cutting performance.

B. AXIS
B-axis has a standard of one degree turning with oversized bearing.
The force driving position between the worm and worm gear has a curved surface which provides 2-3 times higher driving capacity than the conventional complex screws. The driving force is properly distributed, and this ensures the backlesh between teeth is controlled under 0.1mm.


SWING TYPE APC
The MH-series machine has a standard 2 pallet swing type changer system, the load position at the front of the machine allows easy loading and unloading of workpieces. The pallets are positioned and clamped to the table with four precision tapeer 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 component life.


OVERSIZED TAPERED CONES
The B axis movement and Z axis cross movement are equipped with oversized tapered cones for extremely accurate pallet positioning. This assures outstanding machine accuracy.

The bigger O. D. of cones than other makers and over 75% contact surface each other for each pair. The rigidity and the repeatability of continous cutting with 0.001 degree better than the 1 degree divided cutting.

BALL BAR TESTING
LEADWELL uses a stringent ball bar test that checks not only linear accuracy but also machine geometry. This test ensures that each machine meets the three-dimensional squareness and accuracy requirements.

5 AXES ROTARY TABLE (OPTIONAL)
The contouring rotary with a minimum indexing increment of 0.001 offer simultaneous machining factions for complex profiles workpieces. Extra larger preloaded thrust bearings insure smooth and accurate table rotation.
Four clamping cones ensure accurate and repeatable pallet location slong with excellent rigidity.

CHAIN-TYPE MAGAZINE
- 40/60/90 available (MA-500i)
- 40/60/80/120 ABAILABLE (MH-630)

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