Do you know to ensure economic & precise turned parts?

How to Ensure Economic and Precise Turned Parts
2

• When we deal with complex machinery there is
  rarely any alternative to turned parts. Machining
  has given us the precision that we require in
  complex structures and machines. Although it is
  cost effective in the long-run, machined products
  may seem more expensive when you first start out.
  But more often than not many buyers are ignorant
  of the CNC industry and how they can ensure
  cost-effectiveness and precision in their orders.
  
• The secret to a successful partnership lies in
  understanding the others business. It helps in
  ensuring that we come up with a precise order and
  design. This helps the turned parts manufacturers
  to create the right product. It is also necessary
  to ensure economy of operation. Here are few of
  the parameters that must be kept in mind when
  placing an order

Order In Bulk

• Ordering in bulk always gets one economy of scale
  since most manufacturers will offer discounts on
  bulk orders. You can further cut down on costs
  through annual contracts. An annual contracts
  assures the supplier that you are steady and
  long-term customer. You are offered a better deal
  because you are adding value to their business
  through your recurring order.
• But it is not just the steady order that benefits
  your supplier. It also allows them to minimise
  tooling, setup and material costs. They can plan
  for economical manufacturing on their parts a
  benefit that they can then pass on to you as the
  customer. The best way to ensure this is by
  checking the previous years demand and then
  creating a realistic estimate while keeping in
  mind your growth rate. In case there are going to
  be any changes from the original plans, let them
  know well beforehand.

Allow for delivery time

• While its always advisable to go with a supplier
  who can assure emergency delivery, keep in mind
  that such services are usually offered at a
  price. If you want the supplier to deliver your
  products at a less than usual time-frame, you
  will probably have to pay extra.
• A better strategy is to keep sufficient lead time
  during the planning stages. Ask your supplier for
  the optimum order time and the time they will
  take for a cost-effective delivery schedule.

5
Customization and Standard Parts

• Customisation is one of the biggest benefits of
  machined parts industry. But it does come at a
  cost. There are ways by which you can minimise
  the cost of customisation. But the most
  economical way is to go with standard products.
  Every turned parts manufacturer will offer these
  at a lesser rate. Not only does a standard size
  costs less,it is also more likely to be readily
  available. Look for free machining material
  wherever possible. Production costs are less and
  you can get a higher yield.The finished product
  is also likely to require little or no
  corrections. This further brings down the
  production costs and time.
• For instance, if you want special threads instead
  of the standard, the manufacturer has to tweak
  the design. There are chances of errors in
  prototype, which takes time and money to perfect.
  A standard product does not require any such
  special consideration and can hence, be available
  at a short notice and minimal cost.

6
Special pricing for tolerance

• High tolerance is sometimes sought by clients who
  are looking for high dimensional accuracy. But a
  very high tolerance requires special tooling and
  hence, higher costs. Its better to specify
  tolerance that is no closer than what you require
  for actual functionality.
• Be very clear about the tolerance level you
  require and ensure that it is close to the
  standard at the planning stage.

7
Give a detailed design and plan

• Creating a detailed design along with its part in
  the whole structure, helps the parts manufacturer
  to better understand and visualise what you are
  looking for.
• Even if you are hiring them to do the final
  design, your vision is critical in realising the
  actual part. It helps in reducing wastage and
  guides the manufacturer in understanding the
  functionality.

Special features
Special features

• Turned parts manufacturers keep standard tools
  like drills, gages and reamers. If you want a
  significant change from the standard, it will
  require extra tools or effort.
• This could be something simple like full threads
  on screws or different hole diameters. Both
  require special gages and are often harder to
  create.
