Spin Milled - Explain

[alcorn]

I have a been playing vokeys for a while now. I've got the old nickel headed models 52*8 56*10 60*8 and I hit them all reasonably well. But truth is I saw some of the used spin milled wedges at golf smith and I'm somewhat temped. Could someone please explain the difference between the spin milled wedges and plain faced wedges?

This is a spin miled face.

spin milled is refering to the way the were cut the spin milled wedges grooves are cut deeper and wider causing more spin cause it takes away all the grass and dirt from getting in the way of the ball against face contact. all i know is spin milled doesn't nesaserly mean more spin in your case it does but it is just a machine they use to cut the grooves can some one elabarte as i don't feel i did to good of a job

The above pic is what a SM face looks like. Note the circular(spin milled) milling lines not the grooves.

spin-milled has nothing to do with channeling dirt and grass from the club. the spin-milling process is designed to essentially give the face more friction along with the grooves themselves to allow for more bite on the ball, thus more spin. A wedge such as the cleveland which uses zip groves uses a different method to impart more spin on the ball, square grooves which cut into the ball more upon impact for more spin. Some prefer spin-milled, some prefer zip grooves, either way it's just personal feel. IMO, spin-milled give more bite on the ball, especially 3-4 peice balls, and in warm-hot weather consider yourself replacing a ball after almost every crisply hit chip shot.

You guys should check your information before posting things that aren't true... "spin milled" is the CNC process used to make the grooves and clubface. I have worked in a machine shop and know exactly what they are referring to. Don't believe me... check the Titleist website which says this...

Vokey Spin Milled wedges feature a CNC machine cut face and grooves. A special circular saw style cutting tool is used to create precise grooves with a steeper draft angle and a tighter edge radius for increased friction. Vokey Spin Milled wedges have 30% more groove volume than a conventional wedge. This provides more consistent and higher spin, particularly from grassy lies and wet conditions. seems like they focus more on the importance of how the GROOVES were made, not the face... since this is what is responsible for the increased spin.

Is that not a spin milled face? I'll leave it at that.

Do you know what a CNC machine is... ever seen one? Well, the little cutter they use makes those lines, the smaller one used to cut the grooves will make the same lines on the groove bottoms... "spin milling" is the process used to make the wedges. You can continue to believe what you will... but why would you want to mislead others?

Wrong (see below).

Ding ding! We have a winner.

No (see below).

I've answered this question before, and I suppose I'll do it again. This comes straight from people I've asked at Titleist. The "spin milled" part of the Spin Milled wedges is the grooves. As their site says, "Vokey Spin Milled wedges feature a CNC machine cut face and grooves. A special circular saw style cutting tool is used to create precise grooves with a steeper draft angle and a tighter edge radius for increased friction." Look at a Vokey Spin Milled wedge. Notice how the grooves, at the ends, have a radius up to the face? They're cast wedges but the grooves aren't cast into the club - the clubs come out of the casting process with flat faces. They then mill the face to ensure it's flat and add the "micro texture," then "spin mill" to cut the grooves. They do it by turning a saw blade on its side, basically - which gives you that radius at the ends. It just so happens that Titleist also mills flat the face of their Spin Milled wedges, and that the "micro texture" does perhaps add a teeny bit of spin. They don't do this on their 200 series because the 200 series is a lower-spinning wedge, so adding even a little spin to it would be counter-productive. They could, though, and that wouldn't make the 200 series wedge a "spin milled" wedge in Titleist's eyes. Executive Version: "Spin Milled" refers to the grooves.

Questions #6 and 7 under "Spin milled wedge questions" address your particular questions, but listen to the whole pod-cast anyway.

[LBlack14]

That is a SM wedge and this place is starting to remind me of GolfRewind. Maybe you guys should do YOUR homework!

From Golfsmith : http://www.golfsmith.com/products/SE...ged_Wedge_Head

Snake Eyes 655TM Fluid Forged Wedge Head: This wedge head is designed for mid-to-lower handicap players (0-18) looking for soft feeling, versatile wedge that offers many loft/bounce options. 655 Tour Milled wedge heads are fluid forged from a soft carbon steel. This process starts with a raw casting and then subjects the head to a forging press to compact the material and eliminate any voids or air pockets. The soft material is unique in that it is 10% less dense than most carbon steels used in forgings allowing more mass to be positioned in the sole and back part of the wedge. Each head is then individually CNC-milled both on the face surface as well as each scoreline to provide the most accurate wedges possible. 655TM wedges offer contemporary round profiles with soft wedges and a slightly dull chrome finish to avoid glare.

This is a spin miled face.

The "Spin Milling" refers to the way the grooves are made, not the "little circle things" on the face. I, too, have worked my whole career in a metal shop.

This is where you are wrong... the circular "micro texture" is not made using the same process as the "spin milled" grooves. Yes, they are both

milled , but "spin milled" refers to a specific process used on the grooves, as Erik has explained to you. Listen to the podcast in my above post, reps from Titleist explain the difference. I'm pretty sure the guys at Titleist have done their homework

I live next door to a Man that owned his own CNC milling company. You calling him and Golfsmith liars? I may be wrong obout the grooves, but that is a spin milled head. period.

From the US patent office.

Title: Spin milled grooves for a golf club
Document Type and Number: United States Patent 7473187
Abstract: The present invention is directed to a golf club head with an improved striking surface. The grooves are machined into the strike surface with tight tolerances. The grooves have sharp edges, radiused ends, and a draft angle between about 2° and 12°. The striking face is machined such that it has a uniform texture with a roughness of more than 40 Ra.

It just so happens that Titleist

Another thing to consider, like Erik said, the micro texture does add some spin. My CG1's also have this micro texture, and while the difference is small, you can notice it. I switched to the Tour Action in my 3+4 irons for this reason. They don't have that texture, and it seems to cut down on side spin a little. Then again, its so small it could all be in my head. lol

Your missing the point... and prehaps we are spliting hairs here. Yes, that is a spin milled head, you are correct. The point in contention, however, is what makes it a spin milled head. The production of the grooves are made using the "spin milling" process.

[LBlack14]

I give, no more hair slitting for me. Thanks for the info.

That is a CNC machined head with the spin milling process used to machine the grooves.
