5,115 mm

With years of innovation and manufacturing experience on horizontal boring mills, we combine them with the latest Japanese key components to make the MB series provide maximum mechanical performance and strengthen our reputation as a professional boring mills manufacturer.

High rigidity structure combined with a high precision spindle provides excellent machining accuracy and heavy-duty cutting ability.

The rotary working table is supported with hydrostatic bearings. Working table max. load 4,000 kg. B-axis positioning accuracy 0.001°.

One-piece bed structure plus 4 compound guideways are combined with the X / Y axes high rigidity box way to meet with various needs for heavy-duty cutting and precision machining.

The open-space operating area can shorten the distance between the operator and the working area to increase both safety and convenience. Additionally, this compact size machine does not take too much space in the factory.

High Rigidity Structure

SeriesB

The Finite Element Method ( FEM ) provides optimum machine designing and light-weighted structure advantages while ensuring high machine rigidity.

Built to withstand years and years of rigorous high production machining, the heavily ribbed, one-piece thermally balanced bed and casting components are of “ MEEHANITE ” casting.

The 3 axes feed system is adopted with full travel support and uses high precision linear encoders to ensure optimum performance and accuracy.

The X / Y axes are adopted with high rigidity box way which is pre-heated and pre-grinded, suitable for heavy-duty cutting conditions.

The Z-axis is adopted with 4 compound guideways to effectively prevent the working table from overhanging while providing strong and firm support.

The contac t sur face of the bed and column are all precision hand scraped to ensure maximum performance and accuracy.

Large size ball screws are designed with pretension to increase the working accuracy.

The automatic lubrication system uses pressure-relief lubricators and high quality copper oil pipe which gives the right amount of lubricants to the guide ways, ball screws and other key components. The bed and column structure are built in one-piece.

1,800 N-mMaximum Torque

High rigidity closed spindle head design combined with spindle transmission and feeding system provides powerful heavy-duty cutting ability.

Max. spindle speed of 3,200 rpm with 3-step gear box can provide maximum torque output of 1,800 N-m under 137 rpm.

The system uses a Ø110 mm high precision spindle which allows the W-axis travel to be up to 500 mm.

coolingsystem

The spindle cooling system uses oil cooling and water jacket device to give the right amount of coolant to all the bearings, motors, gears inside the spindle box. This effectively reduces spindle thermal distortion and ensures working accuracy.

The inner taper of the spindle conforms with BBT50 tool to provide a firmer grip to the tools which reduces the vibration from the tools.

4,000 KG

The rotary table is supported with high rigidity base which gives full travel support, to prevent overhanging problems and maintain accuracy over long working hours.

Hydrostatic bearings with high resolution linear scales provide strong support, anti-vibration features, low-wear and long life-term advantages.

T h e B - a x i s p o s i t i o n i n g u s e s a p o w e r f u l hydraulic braking system to provide positioning accuracy in any indexing. The r ight angle indexing lock device allows the 90° indexing with more stability.

Optional APC SystemOptional auto pallet changer system which is designed by

AWEA R&D team can efficiently reduce the labor needs, shorten

the time for part uploading to enhance working efficiency.

Four hydraulic clamping devices and disk type spring

locks clamp the table after table positioning, high

pressure air tight detecting device would ensure the

successful locking. Besides, each hydraulic clamping

device has 39,000 N t. c lamping force to provide

optimal cutting rigidity and high accuracy.

APC mechanism is adopted with high rigidity box way

and driven by high reliability hydraulic system, thus to

provide stable and efficient pallets exchange function.

High Reliability ATC SystemHigh Efficiency Chip Conveying System

The carefully designed chips conveying system allows the chips to

automatically fall into the screw type chip conveyor. The chip conveyor

then transports the chips into the water tank and chip container to

prevent heat and chips from accumulating which ensures long-term

working accuracy.

2 sets of chip conveyors are installed between the contact surface of the

saddle and bed which helps the chips on top of the bed to be quickly

transported in to the chip conveyor and also reduces cleaning time.

Standard 40T ATC system. 60T magazine is

optional.

Max. tool load is 25 kg, max. tool magazine

load is 600 kg which can meet various needs of

working condition.
