§ The process

How we do it

Turning is where Holloway started in 1924, and it is still a third of what we do. Sliding-head lathes run small precision parts unattended; twin-spindle turn-mill centres finish complex parts in one hit; the heavy lathes handle shafts up to two metres.

We hold bar stock for common grades, so repeat orders can start the day they arrive.
