GRINDING SHOP OWNERS Tim and Wendy Middlehurst have a wish list of machines they
would like to purchase for their newly
expanded 8,000 sq ft Orangeville, ON,
shop, Hi-Quality Carbide Tooling Inc.
“There are currently eight items on
the wish list,” says Wendy, vice president
and secretary/treasurer of the company.
The new Studer CT960 grinder from
United Grinding is number one on that
list. The grinder was purchased through
United Grinding’s distributor Machine
Tools Systems, Toronto, and installed
this past August.
The new machine is a dream that
took four years to turn into a reality. The
Studer ID grinder is the latest in a line-up of more than 25 machines, of which
nine are cylindrical or surface grinders.
Founded in 1980 by Tim
Middlehurst’s father Dennis, the ISO
9001:2008 certified and Controlled
Goods Program approved company

tooling for cold forming, fastener and
spring industries. The fast-growing
company expanded its facility last year,
adding 4,400 sq ft to an existing 3,600
sq ft and set up a new quality inspection
department featuring a Mitutoyo Crysta-Apex S544 full contact CMM. Today,

grinding services, as well as vertical and
horizontal honing, polishing, wire EDM
cutting (the company just purchased and
installed a new Sodick wire EDM) and
The new Studer ID cylindrical grinder
is the second Studer in the company’s
shop. Hi-Quality purchased the first
Studer, the S33 CNC OD cylindrical
grinder, in 2007.
