PTG Holroyd 推出 HG200 螺旋型面磨削中心
PTG Holroyd Introduces HG200 Helical Profile Grinding Centre
PTG Holroyd Precision 推出 HG 系列新机型 HG200 螺旋型面磨削中心，面向生产泵螺杆及紧凑型制冷、空压机所用小型螺旋件的厂商。该机基于 HG350 模块化平台，可磨直径 200 mm 以内的螺旋齿轮与泵螺杆，型面宽度 50 mm、最大深度 35 mm、工件重量 200 kg。销售总监 Mark Curran 表示，公司把 HG350 模块化平台用于更小机型，以简化生产并给客户更大灵活性，该平台可配置为齿轮、转子、蜗杆和泵螺杆磨削。HG200 采用西门子 Sinumerik One 数控系统，PTG Holroyd 与西门子合作将该系统适配磨床需求。机床还配雷尼绍 OSP 60 扫描测头与 SPRINT 技术，可通过关联的工件测量机实现加工中自动修正，帮助在磨削复杂螺旋型面时保持精度。HG 系列面向深切磨削，具备大功率磨削能力，可选加长床身以容纳更长的螺杆和蜗杆轴，另提供 IO-Link 通信与 RFID 扫描，便于生产单元在换产时识别工件和刀具。标配功能包括坐标自动调整、磨削中砂轮修整、型面管理与坐标测量。HG200 之前，公司已推出 HG350 和 HG500 磨削中心。
PTG Holroyd Precision has introduced the HG200, a new machine in its HG Series of helical profile grinding centres. The machine is designed for manufacturers producing pump screws and smaller helical components used in compact refrigeration and air compressors.
The HG200 follows the launch of the company’s HG350 and HG500 grinding centres. It is based on the modular HG350 platform and is designed to grind helical gears and pump screws up to 200 mm in diameter, with profiles up to 50 mm wide, a maximum depth of 35 mm and component weights of up to 200 kg.
Mark Curran, Sales Director at PTG Holroyd, said the company had adopted the HG350 modular platform for smaller machines to simplify production and provide greater flexibility for customers. The approach allows the platform to be configured for gear, rotor, worm and pump screw grinding applications.
The HG200 comes with Siemens Sinumerik One computer numerical control (CNC) technology. PTG Holroyd worked with Siemens to adapt the control system to the requirements of its grinding machines. The company was the first UK machine tool manufacturer to adopt the latest control technology when it was introduced.
The machine also incorporates a Renishaw OSP 60 scanning probe with SPRINT technology. This allows automatic in-process corrections or adjustments through an associated component measuring machine, helping manufacturers maintain accuracy when grinding complex helical profiles. Mr Curran said PTG Holroyd had worked with Renishaw and Siemens to integrate automatic calibration using the SPRINT probe.
The HG Series is designed for deep grinding operations and features high-power grinding capability. An extended machine bed is available to accommodate longer screws and worm shafts. Other available features include IO-Link communication technology and radio-frequency identification (RFID) scanning, which can help production cells identify components and tooling during changes between manufacturing cycles. Standard onboard functions include automatic coordinate adjustment, in-cycle wheel dressing, integrated profile management and coordinate measurement.
The HG200 expands PTG Holroyd’s range of grinding machines for specialised helical components. The company’s portfolio includes equipment for manufacturing compressor rotors, pump screws and high-accuracy gears, along with technical consulting services. PTG operates through the PTG Holroyd Precision and Holroyd Precision Rotors brands, supplying machine tools for precision engineering applications across industrial sectors.
