近十年来，模具行业通过采用新的加工技术，如CNC电蚀加工或高效仿形铣削加工（HSC），以取代耗时费力的手工操作（如手工研磨）。
德国Lach Diamant公司在最近于法兰克福召开的欧洲模具展（Euromold）上，展示了用于模具HSC加工的仿形铣刀系列，其中包括为加工铝、石墨、玻璃/玻璃纤维增强塑料（GRP/GFRP）模具而专门开发的PCD仿形铣刀和用于加工淬硬钢模具的PCBN仿形铣刀。试验结果表明，与以前的加工方法相比，采用仿形铣削可将加工时间缩短50％。
在今年3月于德国奥格斯堡召开的磨削技术展览会上（GrindTec，最早由德国工具磨床协会发起，现已成为国际性的重要展会），Lach公司展出了用于磨削硬质合金、高速钢和陶瓷材料的金刚石和CBN磨轮系列。这些磨轮既适用于常规磨削，也适用于CNC数控磨削和/或高速磨削。此外，Lach公司还展出了用于普通氧化铝和碳化硅砂轮的金刚石修形工具系列，以及用于PCD工具加工和成形的放电加工机床。Lach公司自1978年率先获得放电磨削（EDG）加工的技术专利后，一直在不断推出新型电加工机床，其最新型号机床Dia-2100-mini将在GrindTec上展出。
The LACH DIAMOND display includes newly developed PCD machining tools for
innovative processing of aluminum.
Foremost the unmatched PCD insert with an integrated chipbreaker (worldwide patents).
This high-tech product, especially in form
of the enhanced processing of forged or drawn
aluminum (with low Sic content) is a must for
the automobile and accessories industries.
The chipbreaker of this PCD insert made by
LACH DIAMOND breaks the chip immediately
following its formation thus preventing the creation
of the long and disturbing aluminum chips.
The working process is not anymore interrupted by chips caught in the system. The aluminum chips are easily removed and prepared for recycling.
PCD inserts with chipbreaker in the most common ISO designs can be supplied from stock.
LACH DIAMOND developed the so-called
»dia-compact« monoblock diamond milling cutter for face and square angle milling of aluminum parts for the automobile, electro industry and their suppliers.
This tool has in the meantime won the 2004 Innovation Award of the State of Hessen.
The PCD diamonds used in the monoblock diamond milling cutter are with the steel bearing element a firm unit. This design allows the milling cutter in the HSC range to run at a cutting speed of up to 15,000 m/min. and a feed speed of up to 120 m/min.
The »dia-compact« monoblock diamond milling cutter is supplied so that it is ready for operation and can be immediately attached to the machine.
The advantages: sharp increase in productivity through a shorter time cycle and lower costs.
Feed of up to 0.2 mm per tooth
Large depth of cut
Suitable for roughing – finishing – fine finishing
Multiple life time/production time through the
LACH DIAMOND regrinding service.
The above information represents just the most outstanding highlights from the program of polycrystalline diamond and CBN tools.
You are welcome at the LACH DIAMOND IMTS Show booth where our staff will be glad to show you around.
We will be pleased to demonstrate to you our new developments in the field of the LACH diamond and CBN grinding wheels, diamond dressing tools and diamond-tipped wear tools.
