Romi’s D Series Vertical Machining Centers Built for Rigidity and Speed

These VMCs absorb vibration to allow consistent production of highly precise parts.

Romi’s D Series vertical machining centers (VMCs) are designed and built, based on customer research, to offer users higher productivity, robustness and precision. The VMCs are built with Romi-made monoblock cast iron beds that absorb vibration to allow consistent production of highly precise parts. In the United States, Romi offers three models — the D 800, D 1000 and D 1250. All three are equipped with big-bore, 40-taper, direct-drive spindles with speeds of 10,000 or 15,000 rpm. A direct-drive system is said to be low maintenance and improves accuracy and repeatability, while the big-bore 40-taper increases stiffness and allows increased depth of cut.

The machines are equipped with thermal compensation (with sensors) to improve precision. Each model features a FANUC 0i-MF i-HMI CNC with 15" touchscreen, and a high-speed package that is said to allow better performance during machining. Linear roller guides on all three models facilitate feed rates up to 1,575 ipm (40 m/min), which allows for precise, fast acceleration and positioning. These guides are also said to increase robustness during machining and higher load capacity (part weight) on the table.

The models D 800, D 1000 and D 1250 have a net machine weight of 20,500 lbs., 21,800 lbs. and 23,000 lbs., respectively; and a maximum machining volume of 31 × 24 × 25 inches, 40 × 24 × 25 inches and 50 × 24 × 25 inches, respectively. Each model is also equipped with a 30-tool automatic vertical tool changer.

Quicktech Turn-Mills Feature Integrated 6-Axis Robot

The machines are designed to perform complex milling with standard live tools, and an optional 360˚ B-axis extends milling capabilities

Quicktech’s i-42 ROBO and i-60 ROBO 4-axis mill/turn centers feature integrated 6-axis Mitsubishi robots for fast, automated loading and unloading of medium-diameter (i42: 42mm/1.68", i60: 60mm/2.36") bar stock. The machines are designed to perform complex milling with standard live tools, and an optional 360˚ B-axis extends milling capabilities. The Mitsubishi S-

series 6-axis, high-speed robot automatically loads, unloads or turns over parts weighing up to 13 lbs. An optional multitray, 4-pallet stacker handling system enables extended untended operation. The robot is contained within the machine and positioned to allow unimpeded operator access for machine setup and operation.

The i-42 ROBO and i-60 ROBO machines operate in four axes (five with the optional B-axis), with a 15-hp, high-torque main spindle that features C-axis capability, a 2-hp live-tool milling spindle, and capacity for 17 tools (23 with B-axis). A standard DIN-173-42B collet chuck provides capacity for 42 mm bar, while an option with a 60 mm collet or 6", 3-jaw chuck offers 60 mm bar capacity. A 3-axis (4-axis with optional B-axis) gang-type vertical tool post serves the main spindle with six OD turning tools, five ID turning tools, and three radial and three axial live toolheads. The optional B axis increases live tool capacity to six radial and six axial positions. The tool post also provides Y-axis motion for off-center milling operations. Rigid tapping is standard, as is the Kennametal KM-25 quick-change system that minimizes tool change time.

A matched CNC system combines a Mitsubishi M80A control, featuring a 260-mm (10.4") LCD with Mitsubishi servomotors and amplifiers. Standard machine features include a bar feeder interface, parts conveyor and catcher, chip conveyor, collet chucks and a 400-psi coolant pump.

Hydromat Rotary Transfer Machines Offer Modular Design Flexibility

Units feature control architecture geared for performance and reliability.

Hydromat’s Epic HF FANUC line of rotary transfer machines can be equipped with collets or chucks for precision metal cutting operations. The modular system consists of horizontal and vertical tool spindles mounted around a precision cast base. Epic HF FANUC machines utilize 12 or 16 horizontal machining stations, and have the available capacity of six vertical tool spindles on a 12-station machine and eight vertical tool spindles on a 16-station machine.

The machines feature control architecture said to be geared for performance and reliability, with FANUC G-code programming, one of the most widely used control languages in the world. The units use standard, affordable induction motors for most common machining operations. According to the company, the Hydromat HMI software provides maximum ease-of-use and reliability for daily operations. The vector spindle drives are located in air-conditioned electrical cabinets, and come with FANUC servo motors with optional Hydromat Shred-Advantage and Thread-Advantage deep machine learning technology.

Operational and control benefits are said to include nanometer resolution, providing high precision and smooth finish surfaces. The company says the units’ hardware is reliable and proven to provide stable performance and maximum operational uptime. With high-speed, high-precision operations, the units are designed to result in high-quality machining with reduced cycle times. Simple, familiar operation allows maximum productivity as operators to get up-to-speed quickly. Connectivity through standard 100-Mb Ethernet interface permits easy process data collection and remote diagnostics troubleshooting. Macros and PC interconnectivity extend the ability of the machine, creating customized process solutions. Simulation tools are said to provide effective training in part programming and maintenance in a safe and stable environment.

The optional Hydromat Shred-Advantage technology enables the feed axis to oscillate with each revolution of the spindle to eliminate stringy chips. With the optional Thread-Advantage technology, the thread mill is said to be up to 10x faster with precise, accurate position control, providing fast, synchronized tapping.

Index Corp.'s MS32-6 Multi-Spindle Automatic Lathe Offers Flexible Tool Slide

Index Corp. launches next-generation MS32-6 multi-spindle automatic lathe.

Index Corp. has launched its next-generation MS32-6 multi-spindle automatic lathe. This version of the six-spindle machine brings the benefits of multi-spindle technology to a broader range of applications thanks to a flexible tool slide platform that reduces change-over times. The INDEX MS32-6 multi-spindle automatic lathe.

The INDEX MS32-6 multi-spindle automatic lathe.

Accommodating up to 32-mm barstock, the MS32-6 easily handles a variety of complex parts, as the machine is equipped with 12 cross slides, with two v-shaped cross slides equipped with X and Z axes located at each spindle position. C and Y axes, together with live tools, can also be implemented to allow for a range of machining processes, including off-center drilling, threading, contouring, hobbing and polygonal turning. All of the machines’ slides can also be alternatively configured for grooving or drilling.

Coupled with the company’s quick clamping device, tools can be set up off of the machine and then quickly installed, reducing tool change times by 50%. Additionally, the machine incorporates the same W-serration system on its live units for drilling, milling and polygonal turning. By presetting tooling for these operations off of the machine, setup times can be reduced by up to 92%.

With the updated MS32-6, users can apply twin turrets with rigid tools in up to five spindle positions. These hydraulically controlled units can alternate between tools in less than half a second, enabling efficient use of separate tools for roughing and finishing in the same position.

The machine’s fluid-cooled spindle drum features six spindles with speeds that are independently controlled to a maximum of 8,000 rpm, allowing optimum cutting data to be applied to each individual cutting process.
