雷尼绍推出 PH20 PLUS 五轴触发测头系统，检测行程达 300 mm
Renishaw introduces PH20 PLUS 5-axis touch-trigger system with 300 mm inspection reach
雷尼绍推出用于三坐标测量机（CMM）的 PH20 PLUS 五轴触发测头系统，用来替换现有的 PH20 测头，检测行程比原测头提升 50% 以上。新系统沿用 PH20 的高速触发测量能力，重新设计的 A 轴采用新的运动学安装座，可支持更长、更重的测针配置，额外增加 107 mm 行程；配 50 mm 测针时，从 A 轴中心算起的最大工作长度可达 300 mm。 PH20 PLUS 定位为 PH20 的直接替代品，兼容现有 TP20 模块（不含加力模块），现有 TP20 模块可通过 PB20 适配器继续使用，原有零件程序和测量策略可沿用，也可配置成与现有 PH20 安装的有效工作长度一致。基于 TP20 测头系统的新 PE20 模块采用更大的运动学安装座，与 PH20 PLUS 测头直接对接，并提供多种长度。 配套的新模块化料架系统安装在 MRS2 导轨上，可装在三坐标测量机台面或机床框架上，包含可配置的 TP20 模块更换端口、PE20 模块温控端口以及分配电力的连接模块；带电源的 PCR20 料架可独立存放多个测头模块和附件。新系统与雷尼绍 UCC 控制器完全兼容，集成方式与原 PH20 相同。IMTS 2026 期间，PH20 PLUS 将在多家三坐标测量机厂商展台演示，雷尼绍人员将在质量保证展台 134314 和 134524 接待咨询。
The PH20 PLUS 5-axis touch-trigger system for co-ordinate measuring machines (CMMs) is being introduced by Renishaw to replace its established PH20 head. It offers over 50% increase in inspection reach over the original head, which will improve access to features deep inside parts and in hard-to-access areas. The new PH20 PLUS system builds on the proven measurement capabilities of the PH20, enabling high-speed touch-trigger measurement across a wider range of applications.
Launched in 2010, the PH20 touch-trigger system utilises the head motion technology developed for the multi-award winning REVO® 5-axis measurement system, which minimises the dynamic errors of a CMM at higher measurement speeds. It has been widely adopted by manufacturers globally due to the substantial increases it has achieved in CMM throughput, boosted by its innovative 5-axis infinite positioning, inferred calibration routines which reduce machine downtime, and the ability to automatically change TP20 probe modules.
The new PH20 PLUS system builds on these benefits with a redesigned kinematic mount that supports longer probe configurations, improving access to part features that can be difficult to reach with the original PH20 system.
"With PH20 PLUS, we've focused on extending capability which we think will appeal to both existing PH20 customers and those with measurement requirements which could previously not be met by the existing head," said Nathan Fielder, Product Manager at Renishaw. "Existing PH20 users will be able to adopt the new head and reuse existing part programmes and measurement strategies, while benefiting from increased reach and greater flexibility."
Increased reach and improved capability
The redesigned A-axis features a new kinematic mount that supports a wider range of probe module extensions. This enables the PH20 PLUS head to use longer and heavier probe configurations giving users improved access to features deep inside parts and in hard-to-reach areas. The result is an additional 107 mm of reach, significantly increasing the accessible measurement volume without compromising usability.
With a 50 mm stylus, the PH20 PLUS head offers a maximum working length of up to 300 mm from the centre of the A-axis, an increase of over 50% compared with the current PH20 system.
Based on the industry standard TP20 probe system, the new PE20 modules feature a larger kinematic mount for direct interface with the PH20 PLUS head and are available in a range of lengths to suit different applications.
Backwards compatibility protects existing investment
The PH20 PLUS system has been designed as a direct replacement for the PH20. The system maintains compatibility with the existing range of TP20 modules (excluding the extended force module), ensuring straightforward upgrades. Existing TP20 probe modules can be used via the PB20 adaptor, enabling customers to keep their current hardware. This supports the continued use of established stylus configurations and existing part programmes, helping to minimise transition effort and protect previous tooling investment.
The PH20 PLUS system can also be configured to match the effective working length of existing PH20 system installations, simplifying upgrade and replacement decisions.
New modular rack system for automated module changing
A new modular rack system has been developed to support automatic and repeatable probe module changing with the PH20 PLUS head. The system mounts to an MRS2 rail, which can be installed on the CMM bed or directly onto the machine frame. It includes configurable change ports for TP20 modules, temperature-controlled ports for PE20 modules, and connector modules to distribute electrical power across the rack.
In addition, the powered PCR20 rack provides a standalone solution capable of holding multiple probe modules and accessories, enabling flexible configuration based on application requirements.
Designed for efficient integration
The new PH20 PLUS system is fully compatible with Renishaw's UCC controller and integrates in the same way as the original PH20 system, providing a direct, drop in replacement for existing CMM installations.
Visitors to IMTS 2026 will be able to see the PH20 PLUS 5-axis touch-trigger system demonstrated on the booths of various CMM manufacturers, and Renishaw staff will be on hand to discuss the new product at the Quality Assurance booths 134314 and 134524.
