In this video, we showcase our cutting-edge turning-milling center, MC-100, tailored for the complete production of heavy-duty truck axles. Utilizing a turning-milling machine concept, the axle itself is rotated, allowing various machining operations— turning inside and outside, turning the steady rest seat, gear milling, milling, drilling, threading, chamfering, and more—to be performed without the need for multiple setups.


This approach ensures exceptional precision in cylindrical and symmetrical components, like truck axles, where maintaining concentricity and surface finish is critical. By rotating the workpiece, the machine achieves consistent machining across the entire surface, reducing complexity and setup time.


For truck axle manufacturers, this system offers:

 - complete flexibility in handling different axle designs and dimensions

 - enhanced efficiency through continuous operations on a single machine

 - optimized setup and cycle times, resulting in increased productivity

 - high repeatability and precision in turning and milling, critical for heavy-duty applications


Key Features:

 - turning process for comprehensive machining of truck axles

 - single-machine operation for all necessary processes: milling, drilling, threading, facing, turning inside and outside, turning the steady rest seat, gear milling

 - on both sides of the main spindles, there is a combined lathe chuck for external clamping (3-jaw-chuck) and internal clamping (mandrel)

 - seamless transition between operations, minimizing downtime

 - flexible setup for varying axle specifications

Industrial Engineering

Industrial engineering redesigns and installs engineering systems primarily. It also examines and redesigns managerial processes that impact productivity in engineering systems. Machine tools and other machines are important components of engineering systems. Industrial engineers have to analyze the currently available machine tools in the market and the existing machine tools being used in the factory, plant and processes to identify more productive and profitable replacement of new machine acquisition opportunities.

This collection offers you information on new machine tools and application of new machine tools to increase productivity to help you in giving ideas and directions in developing alternatives for your current machine tools in operations productivity improvement exercises/studies.

Reasons for buying a  new machine tool: Increase productivity, increase capacity, reduce costs, new machines for new products,  tighter quality standards, process flexibility,  and make more parts instead of buy. 

Analysis of of the appropriateness of existing machine tools and the scope to utilize new machine tools that are being offered by various companies is also part of facilities industrial engineering. Industrial engineers need to evaluate the existing facilities every year to find opportunities for replacing them for productivity.

The machine tools and other production equipment are also examined during process improvement studies using process charts. Each time an operation is being examined, the opportunity of using equipment that is available with outside vendor is to be compared with using the equipment available within the company. This is the comparison of the element of work being currently done with the best alternative available.

"Ultra narrow" machines for high speed, high volume
MAZAK recently introduced the new UN Series of high-speed horizontal (left) and vertical (right) machining centers, the UN-600/30H and UN-600/30V, respectively, to address requirements for high productivity, reliability, maintenance and automation in automotive manufacturing.

Designed for the mass production of automotive components, these #30 taper machines feature an extremely small footprint (as indicated by their UN designation, for "ultra-narrow") and are up to three times more productive per unit of floor space than normal-sized machines, according to the developer.

UN Series machines are automation-friendly, allowing multiple machines to be placed together and tended by one robot.

The width of the UN-600/30V vertical machining center is 27.4 in.; it can accommodate a maximum workpiece diameter of approximately 23.6 in. This is possible because of the interpolated machine C- and Y- axes for the X-axis, which is programmed in the same way as a conventional machine X-axis.

The UN-600/30V offers 20-tool storage capability.

The UN-600/30H horizontal machining center has the same, 23.6 in. maximum workpiece diameter and is substantially smaller than other horizontal machining centers in its class. This is due to a compound X-axis, whereby half of the axis stroke is on the machine table and the other half is on the machine column.

The UN-600/30H features 30-tool storage capability.

New integral spindle/motors are used for faster acceleration/deceleration to provide unsurpassed high productivity. The UN Series machines feature high-speed 20,000 rpm machine spindles that accelerate to top speeds in just 0.55 seconds, and perform synchronized tapping at 8,000 rpm.

Five-axis vertical machining for faster production

MAKINO’s latest full five-axis machine solution is the DA300 vertical machining center, combining speed, precision and flexibility for complex part applications. The DA300 “delivers the highest productive capabilities for multi-axis workpieces in the smallest of machine footprints.” 

It is developed as a single setup, multi-side accessible, or full-contouring operation for processing complex parts comming in industrial hydraulic and pneumatics elements, optical, electrical and semiconductor components, medical and dental products, diecastings, automotive components, and aerospace parts.

“The DA300 integrates numerous features that increase productivity and efficiency by providing significant reductions in non-cut time.  “The machine provides a 50% reduction in spindle acceleration time, 15% reduction in positioning time, 40% reduction in tool-change chip-to-chip time, and (it) includes a standard vision-type broken-tool sensor [Vision B.T.S.] that optically checks tools outside the work zone to ensure tool consistency and part quality while simultaneously reducing non-cut time during tool changes by 80%.

When all of these time savings are combined,  dramatic advantage in reduced part-production times and increased profitability can be obtained.

The DA300 worktable is an integral, 340X300-mm table, accommodating workpiece sizes up to 450 mm in diameter, 400 mm tall and weighing 250 kg. The machine provides X-, Y- and Z-axis travels of 450, 620, and 500 mm, respectively, at feed rates of up to 60,000 mm per minute.

The direct-drive, motor-driven A-axis table offers 150 degrees (+30 to -120) of tilt capability at 100 rpm. The rotary C-axis has full 360-degree rotational positioning at 150 rpm. Combined, these rotational axes have the range and speed necessary for high productivity in complex five-face or full five-axis machining.

High Speed Machining of  Bulkhead at Raytheon Aircraft Makino (Mason, Ohio) MC1516 high-speed horizontal machining center


Raytheon Aircraft Company (Wichita, Kansas) does industrial engineering, that is continuous improvement in engineering. Attention is given to  maximize throughput and efficiency. 

Raytheon engineers came to know about high speed machining and  decided to use a Makino (Mason, Ohio) MC1516 high-speed horizontal machining center with a seven-pallet modular machining center (MMC) to machine  bulkhead.   MC1516's Jet 50 spindle provides up to  15,000 rpm. The 50 taper spindle provides horsepower at various ranges and brings a high level of rigidity.  

To machine the bulk heads,  end mills reach 12,500 rpm and achieve metal removal rates as high as 320 cubic inches per minute.  In two setups, the MC1516 machines thin wall tolerances under 0.00010 inch to near net shape. Roughing and finishing are conducted simultaneously using carbide end mills.

The seven-pallet MMC allows the spindle engagement for more than 90 percent of the time. The MMC allows setups offline and keeps the MC1516 constantly fed.

The new technology adoption had challenge of learning quickly. The team consisting  of people in every discipline involved in the process, from manufacturing engineers, programmers to the operator  worked with Makino to learn and optimize the new process. The planned learning paid off with production parts being machined immediately after installation. Raytheon quickly realized the efficiencies, such as reduction in machine and labor hours per part. The machine uses  universal vacuum fixturing also. While the larger bulkhead is machined on a dedicated fixture, vacuum fixtures allowed operators to set up smaller parts in one operation.

The successful process improvement using high speed machining  will be extended to more parts.
