What Lapmaster International does

Lapmaster International (operating commercially as Lapmaster Wolters under Precision Surfacing Solutions Group) is a privately held US-headquartered manufacturer of precision surfacing equipment, consumables, and aftermarket services for industrial customers requiring micron- and sub-micron-level flatness, parallelism, and surface finish. Its product platform spans lapping machines, fine grinding machines (using diamond and CBN superabrasive wheels with lapping kinematics), polishing machines, single-wafer processing systems for silicon and silicon-carbide substrates, multi-wire saws (DW288-S4), optical pitch polishing machines, dual-face machines, thru-feed grinders, buffing machines, and automation/special-purpose systems. The technology core is abrasive-media precision surfacing — proprietary slurry formulations, superabrasive wheel bond chemistry, and Peter Wolters AC microLine wafer-processing know-how — protected through nine heritage brands (Lapmaster, Peter Wolters, ELB, aba, REFORM, KEHREN, ISOG, MICRON, Barnes) with cumulative experience exceeding 200 years.

The business model combines one-time capital-equipment sales with a recurring consumables stream (diamond slurry, abrasive powders, polishing pads, composite plates, fine-grinding wheels) and a multi-year aftermarket services layer including contract lapping/grinding/polishing, factory-trained repair, a 10-year spare-parts guarantee, retrofit and overhauling, and digital support via RangeCare remote diagnostics and Datacare process-data management. Go-to-market is direct enterprise sales through 11+ offices in the US, China, Germany, India, Japan, Korea, Switzerland, Taiwan, and the UK, supported by application-laboratory process development and trade-show presence at CCMT, Semicon China, and Optatec. The customer base spans semiconductor and photovoltaic wafer manufacturers (post-2019 Meyer Burger integration), automotive, aerospace, medical devices, optics and electro-optics, bearings, MEMS, technical ceramics, mechanical seals, and cutting tools, with 9,000-10,000+ active global customers and 150,000+ installed systems supporting revenue diversification across cyclical and secular-growth verticals.

Partnerships

One partnership is on record.

• Meyer Burger Technology LtdmajorStrategic or Co-development Partner · 7 February 2019Acquisition of Meyer Burger's wafering equipment and service business for photovoltaic and specialized substrate material (for semiconductor and sapphire industries). PSS acquired the business for CHF 50 million in cash plus earn-out based on 2019 revenue levels. Approximately 70 employees at Thun location and 26 globally were taken over. Manufacturing activities for non-PV wafering continue in Thun, Switzerland under long-term rental agreement, while PV wafering production remains in China. PSS gained Peter Wolters AC microLine technology and wafering portfolio synergies.
