Grinding

GRINDING

The Miura grinding process ensures that each club head and model is ground to perfection.

OUTLINE GRINDING

The grinding process has many stages, the first being the outline grind. Miura has developed a unique procedure that grinds each model and club head profile with precision. This process ensures there is a consistent look to each individual head which would be difficult to achieve if done by hand.

FACE GRINDING

The face grind is done with a machine that adjusts the depth and grooves. During this process, the Miura craftsmen ensure the groove shape and subsequent performance specs are produced to meet the R&A and USGA requirements. For Miura wedges, the CNC milling machine is used to refine the grooves. This allows Miura wedges to produce the maximum spin permitted.

BLADE AND HOSEL GRINDING

An accurate top line is created during this step. Once the top line is complete, the grinding of the hosel follows. Since the player’s eye will move from the top line, to the hosel, and up the shaft—the grind must be precise. Each worker on the grinding line must ensure this stage is completed to perfection.

In order to reach this stage, the Miura factory has produced three individual sets of dies for each model and loft. Dies alone will not deliver a quality iron—each model needs a precise amount of heat and force. Forging also requires the skill, patience, and experience of a Miura craftsman.

SHAPING

Shaping is most important step of the grinding process. It is responsible for the seamless transition from short to long irons. Each iron has its own build and there are many components that go into shaping a particular iron. Adjustments to the top line, leading edge, or toe profile can help a golfer gain confidence, but requires the grinder to make those changes without altering the club head’s performance.

WEIGHT ADJUSTMENT

Shaping is the most important step of the grinding process. It is responsible for the seamless transition from short to long irons. Each iron has its own build and there are many components that go into shaping a particular iron. Adjustments to the top line, leading edge, or toe profile can help a golfer gain confidence, but requires the grinder to make those changes without altering the club head’s performance.

ADJUSTMENT PROCESS

An integral part of the grinding process involves ensuring the lie, loft, and offset of each club head is balanced. Although these weights are measured during the manufacturing process, confirmation at this stage allows the Miura craftsmen to complete the grinding process with confidence.

Any changes to the lie or loft will have an inevitable effect on the club head. When an adjustment will have a negative impact, additional alterations will be made.
