NOMURA COMES WITH THREE SERIES:

When it comes to buying a new CNC horizontal boring mill ,we know that you are looking for a machine tool that is built to handle the most demanding jobs in your shop. As the old boring mills are fading away, we looked for and found Nomura as a great choice for a horizontal boring mill replacement.
We became a Nomura Horizontal Boring mill distributor because Nomura meets our stringed qualifications in a CNC machine tool that we sell. It is very important to us that we sell quality machine tools to our customers. Read about the rich and honored reputation that Nomura has in the machine tool industry. We found their construction, use of the highest quality components, and the finest FANUC Control, to be an easy sell for us to represent Nomura. We invite you to read below the quality that is built into each of the Nomura CNC Horizontal Boring and Milling series offered.
NOMURA CNC TABLE TYPE HORIZONTAL BORING AND MILLING MACHINE: HB-135 SERIES
NOMURA: HB-135 SERIES
The NOMURA HB-135 Series has continued improvements while it maintains the basic tenet of machine tool technology-functionalism.
The HB-135 Series was designed to accommodate large and heavy work-pieces.
This HB-135 Series has proven mechanical principles, the highest-grade and synthesized components, operational friendliness and inherent craftsmanship that will ensure many decades of superb and unparalleled performances.
The Development and Design Guildelines:

-
RIGIDITY: Fully utilize the axes, strokes and table size:
-
The cross section of each major component has been increased, on average of 150% of the industrial norms.
-
This provides a superior dampening capability, less vibration, and a twist and distortion ratio 200% better than conventional designs.
-
Precision machining is obtained even at the upper reaches of the Y axis and on the corners of the table.
-
-
ACCURACY: Heat and friction were minimized at the lowest level to assure excellent accuracy.
-
Circulating, cooled spindle oil is employed to provide a mist lubrication of the spindle bearings and a coolant jacket for the outer spindle and spindle motor flange.
-
Additionally, the slideways are a fluorocarbon resin coated and force-lubricated.
-
All moving components are free from heat an distortion.
-
-
POWER: Optimize the cutting capability:
-
Exacting cross calculations of machines rigidity creates the perfect compliment, a 37/45 kW (50/60HP) main spindle motor , which, in combination with the three-gear transmission, provides up to 3,970Nm (2,930 ft -lbs.) of torque across the variable speed range of 5-3,000 rpm.
-
Further combined with direct servo/screw couplings and a Z-axis speed reducer, this powerful, integrated system provides a superior performance across a wide range of high speed and/or heavy duty machining requirements.
-
-
THE HB-SERIES is comprised of three models:
-
HBA: With ATC.
-
HBP: With ATC and APC.
-
HBN: Without ATC and APC.
-

The HB-135P-R5's Boring Spindle:

The Rigid Bed and Saddle:



-
The cross sections of the column have been enlarged, on average, by 150%.
-
This added thickness has improved both the twist/bend and distortion resistance ratios to that of a level twice as resistant as that which is found on conventional machinery.
-
With provision and inclusion of the chip conveyor, chips and cutting fluids can be readily collected and disposed of, greatly enhancing the machine's conditions and performance.
-
With the basic design of planer type, no overhang of the Table is at all caused.
-
A Plain Table Type is also available if this design doesn't fit your applications.

NOMURA'S PENDANT CONTROL BOX:
-
Both the machine's switches and controls and the CNC device's keypad and display screen are ergonomically concentrated in a single control unit.
-
The CNC display unit shows all the details of the machining process that simplifies preparation, checking and operation.
-
The detachable manual pulse generator makes set-up much easier as the machine movements can be manually accomplished from the MPG.
-
Nomura utilizes the highest quality FANUC control on their machine tools.

Rotary Table:

-
The combination of rational rib arrangements in the over-sized, thick-walled major components has resulted in more rigidity, better damping and less vibration than that found in most single unit machines.
-
On the occasion that the spindle is positioned at the upper position of the Y Axis, absolutely heavy-duty machining is assured.
-
The extra-large rotary table has a 1,800 x 2,000 mm (70.8 x 78.7 in) working surface that can carry a 15,000 kg (33,000 lbs.) load, more than adequate to handle BIG and HEAVY work-pieces.
-
The slide-ways of the table-base are engineered to the maximum radius, and become as one unit when clamped to the rotary table.
-
The Rotary Table has a maximum loading capacity of 15,000 kg (33,000 lbs. )
-
The table is equipped with a rotary scale, NC or manually controllable to a minimal increment of 0.001 degree.
-
The Ball Screws and Feed Servo Motors are directly linked, preventing backlash for accurate contouring commands.
-
The Z -Axis incorporates a speed reducer to generate the maximum continuous thrust force of 29,400 N (6,600 lbs.).
-
The large diameter Z-Axis ball screw and its incorporated speed reducer work together to complete precision machining for the various shapes, materials, and tooling requirements of today's work-pieces.
-
Each of the Series' models are equipped with both telescoping and retracting covers for their respective guide and slide ways.
-
This protection prevents chip contamination of, or external damage to the sensitive surfaces of the ways.
NOMURA CNC TABLE TYPE HORIZONTAL BORING AND MILLING MACHINE: HB-110 SERIES
NOMURA HB-110 SERIES Has High Rigidity, Accuracy & Power


The Nomura HB-110 CNC Table Horizontal Boring & Milling Machine attains its high precision by the technologies that Nomura has refined over the 100+ years of building machine tools.
The heavy-duty cutting is made possible with an integrated design that takes advantage of the rigidity of each main component.
SPECIFICS:
-
The spindle undergoes more than 20 processes from nitriding to super finishing, which ensures long years of use with minimal wear.
-
The adoption of the nose type spindle head allows better accessibility to the workpiece and reduces the extended amount of the spindle, which provides rigidity and permits heavy duty cutting.
-
By attaining higher spindle speeds and faster rapid feeds, the workpiece cutting time has been shortened, which improves your productivity.
-
The HB-110 employs a high output AC 18.5/22kW (25/30HP) motor (30min/rating) for the rotation drive of the spindle, 2 stage stepless speed change over a wide range is possible and the high torque is obtained.
-
The main bearings of have super high rigidity and precision and are used to assure high precision in the spindle rotating system.
-
The elaborate spindle preparation involves more than 20 processes, from nitride heat-treatments to super -finish grinding, so as to assure wear and deterio-ration resistance.
-
Since the bearing components of the spindle are equipped with mist lubrication, and the outer spindle and motor flange employ an oil- jacket cooling system, they are free from heat and distortion caused by friction, and support high speed cutting and heavy-duty machining.
-
For the main parts such as the bed, saddle, column, etc., Nomura uses a high grade cast iron for the box frame structure that has a high rigidity has been used.
-
With the rational rib arrangements, static rigidity as well as dynamic rigidity (especially vibration dampening) are outstanding.
-
A large diameter ball screw is used to ensure rigidity in the thrust direction from the cutting load, and the double anchor system supports both ends of the ball screw.
-
As the guide groove for the way-cover receiver is machined at the slideway, the slideway of the machine is protected from dirt and stain.
HAND SCRAPING:

With our vast expertise in machine tool rebuilds, we can attest to the need for hand scraping the machine tools during the building process.
No machine can obtain the degrees of flatness, squareness and straightness that hand scraping can do. Nomura, with its high-precision, high quality components, and the hand scraping has built a Horizontal Boring Mill worth its weight.
