Cleanliness is now a quality issue
Keeping products clean is becoming a more significant part of manufacturing as standards for cleanliness, deburring, and finish grow more stringent.
“We’re finding that more and more companies continue to incorporate lean principles into their everyday manufacturing processes,” explains company spokesman Roger Hesse, Stoelting Inc. (Kiel, WI).
“However, one challenge many ‘lean’ companies face is the issue of maintaining part cleanliness standards in a one-piece flow environment. To meet tight cleanliness standards, many companies previously cleaned parts in large centralized batch systems, which have the advantages of longer dwell times and concentrated energy sources such as ultrasonics, agitation, and turbulation. However, they are now looking for less cumbersome, more streamlined one-piece flow-through cleaning processes.
“The challenge for the cleaning equipment manufacturer has been to develop cleaning systems capable of cleaning critical parts ‘one-piece-at-a-time on a continual flow-through basis.’ This must be done while maintaining customer cleanliness standards, which in many instances have become even more stringent in recent years,” Hesse concludes.
At IMTS Stoelting will feature a Nearfield, one-piece flow-through, high-end critical cleaning system as well as a Versaforce automated cleaning cell.
Standards of cleanliness are being formalized in industry. Before ‘how clean is clean’ was established on a situation-by-situation basis, now formal standards are evolving. To meet these needs, Sugino Corp. (Itasca, IL) is offering a new high pressure U-Jet cleaning unit. “In general, manufacturers are being held to higher standards of cleanliness,” states company representative John Fisher. “Not only must suppliers remove chips and obvious contaminates, they often are responsible for removing all coolants and cleaning fluids. Entire shipments have been rejected because the buyer found traces of solvent on ordered parts.
“At the IMTS booth we are going to emphasize our company’s diversity. We are not limited to cleaning and deburring equipment. We offer a wider variety of equipment to support machining operations. A major innovation will be our SSV ballscrew unit. In addition, we will offer a number of pumps, high-accuracy servo units, and drilling and tapping equipment.
Motors are among the key machine tool components. Here’s how one major supplier views the market.
“Reducing the total cost of ownership is definitely the mega-trend in the global industry, says Manfred Grundke, chairman of the executive board, Bosch Rexroth AG, Lohr, Germany. “Rexroth recognized this trend years ago and has developed a business model that reflects this demand. We offer components with superior performance, like our new machine-tool control, the IndraMotion MTX, one of the fastest CNC controls available.”
In another view of motion control. Paul Webster, CNC motion manager, GE Fanuc Automation (Charlottesville, VA) explains, “We are also increasing system flexibility. Servo features in spindles like positioning and contouring are more common. Live tooling functions such as rigid tapping, velocity control, and 6000 rpm or higher servos for servomotor are following a similar trend. These features are common in compound and dial-type machines. These same machines demand better waterproofing of drive systems. IP-67 is becoming standard in servos with IP-68 being requested.
“Additionally, we are putting all features into more economical packages. The distinction between the low and high-end system is becoming more blurred as overall performance increases.
“While the overall trend is to less complicated/inexpensive systems, linear motors, built-in spindles and torque motors are slowly gaining popularity. As the economy improves, drive systems that require more design effort will gain ground. The performance benefits of these systems have been well known, but the additional expense of design work made them difficult to implement during harder times.
“The need for a competitive advantage in high-speed machining is making advanced spindles, high-speed linear and torque motors an attractive option. Built-in and direct-drive spindle motors offer higher rpm and rigidity than belted or gearing options and are becoming more popular in the machining-center market. The spindle market is being driven by these high-speed requirements and is producing spindles capable of high speed [over 15,000 rpm], but also high power output.
“The processing speeds of current CNCs allows faster control loops, vibration suppression functions, and servo features. Processor speeds will continue to get faster, as they look for even more stable servo control and higher speeds and resolution.”
At the show, GE Fanuc will demonstrate a plant application in a special automotive area. Attendees will see:
- A simulated dial index control system featuring the new Series 30i CNC with 32 motors and eight spindles;
- An assembly application suite based on Cimplicity Machine Edition software and a PACSystems RX3i programmable automation controller (PAC) with a new motion control module;
- An automotive body shop application featuring Cimplicity Machine Edition software with Ethernet I/O connections and a PACSystems RX7i;
- Cimplicity Manager software providing backup and restore to CNCs and PLCs; and
- The Proficy Plant Applications manufacturing execution system (MES) software-which enables plant managers to gain clear insight into production processes to more efficiently manage their operations and achieve peak performance.
Loose, wet chips, usually considered a necessary evil, may be a greater source of profit in today’s economy.
“We are seeing much better activity than we did two years ago,” says Dennis Sultany, vice president, Puckmaster Inc. (Minneapolis, MN). “Many companies who have not upgraded their equipment in some time are placing orders. Some are buying because of improved business, and others because they have worn out equipment from lack of upgrading for a long period.
“Our equipment offers two advantages. First, it compresses chips into solid blocks or pucks that can be easily handled. Second, we recover machining fluids for reuse. For every 1000 lb [453 kg] of scrap we recover, we can send 20 gal [76 L] of fluid back to the machine’s coolant flow. Pay-off for our machines is greatly improved by the current booming scrap market.
“We will show four machines at IMTS. Three are chip and fluid recovery machines in various sizes, including a portable unit for smaller shops. The fourth is a shredder which breaks down larger scrap, and also removes unwanted foreign solids from the scrap, such as stray metal parts and broken bits.”
Fluid power is still an important part of machine-tool drive systems. Despite some inroads by electric and pneumatic system, hydraulic actuation systems are still commonly used, particularly where heavy forces are involved or power is needed in small areas. Hydraulic systems also do a better job of carrying off heat and offer long-term reliability.
William Wessman, product manager, Eaton Hydraulics (Eden Prairie, MN) notes a number of trends in hydraulic valve design. “This includes a trend to lower solenoid power. We have a new line of solenoid valves that operate on very low power. The user drives these valves from the PLC signals. There is an amplifier within the valve. This means lower control cost and less energy consumed. Usually the tradeoff when solenoid power is reduced is less force to move the valve. This can mean problems with very heavy loads, or when contaminants are present in the fluid. With the on-board amplifier system, this is not an issue.
“There is also a trend to better sound attenuation. This has been achieved with integrated pump/motors where vibration is minimized.”
Continental Machines (Savage, MN) is another manufacturer offering valves used in machine tool control. According to company spokesman Ron Neitzel, “The latest offering will be a proportional valve with onboard electronics. It will have onboard diagnostics that will allow remote problem diagnosis. This design uses Windows-based programming.
“The market is chiefly OEM and the valve can be used on virtually any hydraulic system for motion control.”
At IMTS Stoelting will feature a Nearfield, one-piece flow-through, high-end critical cleaning system as well as a Versaforce automated cleaning cell. “Additionally, we are putting all features into more economical packages. The distinction between the low and high-end system is becoming more blurred as overall performance increases.

Tuf-Trac magnetic chip and parts conveyors provide maintenance-free handling of ferrous chips, turns, small parts, and stampings. Permanent magnets move inside an air-tight submersible housing to attract and hold ferrous pieces. The conveyors place magnets on 305-mm centers supported by twin roller-drive chains riding in oil-impregnated polyethylene track. Ceramic or Erium rare earth magnets glide ferrous material along a stainless steel, self-cleaning slider plate. Standard models vary in shape from straight horizontal to multiple doglegs including low-profile units in widths from 203 to 1118-mm wide.
Two new lifts include the DryLin SLW, a compact, flat linear table with a spindle drive. It’s the first spindle-lift table available as part of the DryLin W linear guide system. The table delivers great torsional strength at a height of just over 1 1/8″ (28.6 mm). DryLin HTSP is a low-cost, plastic spindle-lift table available with DryLin R linear bearings. The HTSP is equipped with plastic crossbars and slides. Weight can be further reduced by combining the table with a carbon shaft and aluminum spindle. Stroke is always adjustable, manually or via servomotor.
