HPC offer a very wide range of machining services. We aim to provide a complete turning service for any type of component up to around 10" diameter. We can also manage the entire component supply chain which might include machining, anodising or plating and stockholding for call off/kanban.

Slidinghead Turning


We have years of experience when it comes to slidinghead machining so whatever your requirements we can hopefully advise you. We have 10 Citizen slidinghead lathes that can operate around the clock. We do need reasonable volume for these machines (ideally 100+). We have recently purchased a LFV machine from Citizen (Low Frequency Vibration) which ensures we can chip any type of material and reduce production problems.

Fixed Head CNC Turning


We have our own fixed head turning facility consisting of a variety of Nakamuras and Doosan CNC Lathes. All the lathes have powered face and side milling tools and also angled milling and drilling capability/
We are very pleased with our latest purchase of a Nakamura WT-150 Twin spindle Twin Turret machine with Y-axis and barfeed.

CNC Milling capacity


We can offer milling capacity through our sister company Hemlock Engineering Ltd.
Most of the 3 axis milling machines are geared up with 4th axis units and/or multi vice workholding systems which enable us to clamp up to 8 components in a single operation. This means that cycle time is extended. This gives time for the operator to do other work within cycle - such as inspection - and also reduces the number of overall operations.

Order Processing and Production Control
  • From incoming enquiry to final despatch, all products are tracked, controlled and documented using our own bespoke "Route Manager" production control system.

  • Each operation is progressed as the previous one is completed, ensuring all operations are completed fully and in the correct order.

  • All levels of traceability and documentation (C of C's, Raw Material traceability, Inspection records etc.) can be offered.

  • Original enquiry information can be accepted in electronic form.
    We can accept e-mailed drawings or even solid models in many formats such as PDF(*.pdf), IGES(*.igs), DXF(*.dxf), Parasolid(*.x_t),  SolidEdge(*.par) and SOLIDWORKS(*.SLDPRT).

Quality Control
  • Our organization is fully accredited to ISO 9001:2015  by a UKAS Acreddited body (NQA).

  • We supplied components to many safety critical industries for many years - such as train braking systems and fire suppression systems.

  • All orders are subjected to in-process and final inspection.
    This inspection and sampling program is tailored to the complexity of the individual component and the requirements of the client.
    Critical to Quality Dimensions are automatically recorded and stored in a database

  • Our inspection equipment is among the most up-to-date available today. For example, we use a VICIVISION Video Inspection System, enabling us to perform fully automated and highly detailed inspection than possible using manual methods. This equipment is guaranteed to +/- 3micron accuracy.

  • Cleaning and packaging is of the highest standards and for many customers we supply components in tailor made packaging, to suit both the component and the customer's goods receiving / production systems.
