High-Performance Inspection Probe
Introduced for Machining Centers

Renishaw Inc.‘s new OMP40 probe is a significant development that brings the benefits of automated part set-up and in-cycle gaging to small machining centers and high-speed cutting machines. With the OMP40, you can realize the benefits of probing, including reductions in set-up times of up to 90%, reduced scrap due to setting errors, reduced fixture costs, and improved process control.

The OMP40 uses miniaturized electronics that allow an ultra-compact probe that is 40 mm (diameter) by 50 mm (length), while still delivering a metrology performance of 1µm repeatability.

The OMP40 operates with Renishaw’s optical signal transmission system and is a further development in the company’s extensive range of products for machining centers. It was designed to meet a demand for probing on small machining centers and an expanding family of high-speed machines fitted with small HSK and small-taper spindles.

The OMP40 features a 360° optical transmission system with a range of up to 3 m, allowing probe operation in any spindle orientation. The result is simplified system installation and set-up on small machine tools, making the OMP40 suitable for retrofitting to machines without probing.

 

Latest Version of Handbook on
Machine Tool Resources Now Available

The latest version of a valuable resource on the world machine tool industry is now available from The Association for Manufacturing Technology. The 2002-2003 Economic Handbook of the Machine Tool Industry offers the latest information on the US and global machine tool industries. It covers employment, machine tool shipments, machine tools in use, and the financial condition of the industry by location.

The handbook contains approximately 300 pages including written overviews and an explanation of terms. Both product-specific and country-specific data are included. Information on capital equipment purchases is broken out for several major consuming industries.

 

AMBA Creates New Chapter for
Northern Ohio; 22 Firms Sign On

One of the more extensive association for the mold industry and one dedicated to mold makers is the American Mold Builders Association which has announced the organization of its 12th chapter, the Northern Ohio Chapter. In a summer meeting, 36 individuals from 22 companies throughout Ohio agreed to the formation of an official chapter. Dave Hunt, vice president of Hunt Machine & Manufacturing Co. in Tallmadge, Ohio, will serve as chapter president. Hunt is the third generation of his family to operate the 50-year-old mold making business. Assisting Hunt on the steering committee to select officers and committee members are Tom Nahodil and Dave Kuhary of Industrial Mold & Machine in Twinsburg, Ohio.

AMBA has grown from its original roots as a Chicago-based group to a national trade association with over 400 member companies with 9,000 employees and representing in excess of $2 billion in annual tooling sales. AMBA has chapters in Arizona, the Carolinas, California, Chicago, Milwaukee, Indiana, Minnesota, Upstate New York, and three chapters in Michigan.

What is DFM-Design For Manufacturing

Design For Manufacturing ( DFM ) is the the company’s initial idea prior to mold plastic parts design. Its main target is how to design the mold core part of a plan to meet the requirements set plastic parts. Its content is mainly formed of the gate, parting surfaces, core-pulling ideas.

  • gate design: by the Pro / E of Plastic Adviser of the plastic parts were filled gate position and performance analysis, can find the appropriate position into the plastic. Since the gate point is set in the shape of the surface of the plastic parts, the need to minimize traces of pouring, and taking into account its own mold can pull waste drying track, so a point into the plastic.

  • sub-surface: Plastic Housing Knobbie open mode direction is vertical upward, and set draft is of 1 °. Sub-surface plastic parts should be selected in the bottom surface, it is a good mold release and will not affect the appearance of the quality of the plastic parts can also use the gap and core, thimble, etc. into the sub-gap discharge. To facilitate the process, improve accuracy, the child in plastic molded side hook grooves. This allows the shape of the sub-surface of a plane, more convenient
  • pulling mechanism design: careful observation of three-dimensional model of the plastic parts can be found there is a need to use the slider slot for easy mold after molding. It requires the use of angle pin block side parting pulling mechanism.

H 13 mould steel and H 13 die steel mechanical properties

4Cr5MoSiV die steel die steel, referred to as H13, is a kind of air cooling type heat hardening die steel, wCr=5%, the hardenability of $150.m steel is very good, under air cooling can be hardened. H13 die steel temperature has the toughness and wear resistance of high strength, good heat in, under working temperature with thermal fatigue performance, good anti in addition, good oxidation resistance, small distortion of heat treatment. The mechanical properties of Hl3 die steel Higher Hl3 die steel heat resistance and wear resistance, and toughness similar hardenability is good, is a good material for the production of forging die. Due to higher toughness, even in the quenched state also have certain toughness, thermal fatigue resistance is particularly good, so use it for making high speed hammer forging die is very ideal, and sometimes also used for the production of die casting mold, extrusion mold etc.

Plastic Mold  maintenance and repair matters needing attention

Mould repair note:

1 disassembling the mould, avoid bumping and the water spray, mobile tostationary.

2 spray hot die, then spray a small amount of release agent

3 to conduct a comprehensive inspection of the mold and anti rust treatment: carefully wipe dry cavity, core, the top of the water and sundries institutions and for position and other parts, and spray mold antirust agent and butter.

Maintenance of the mold

In the process of plastic mould in continuous work, due to wear, easy to cause themovement of parts in the process of lubricant deterioration, leakage,pressure injury issues such as plastic materials, the need for mold maintenance.

Mold maintenance is generally divided into the daily maintenance and lower die maintenance

Mold maintenance generally include the following aspects:

1 regular derusting (appearance, PL surface, cavity, core etc.)

2 regular re add lubricant (ejection mechanism for etc.)

3 regular replacement of wear parts (rod, bolts etc.)

4 other places that need attention

Die mold maintenance required by the professional maintenance staff will die after removal of the mold cavity of the mold, a thimble test protection professional.
