Process: Drilling

Overview

 

Drilling is a method for creating or enlarging holes in a component.
When drilling, a drilling machine is lowered towards the workpiece. When the rotating cutting tool reaches the component, a hole is cut. The diameter normally ranges from 1/8 to 1½ inches, sometimes expressed in millimeter. It is possible to make larger or smaller holes, but it usually requires different production techniques. The ratio between the diameter and the depth of the hole ranges from 1:1 to 1:10. Although it is possible to do other ratios, it normally requires special tools. This is frequently used within the aviation industry.

There are a few different kinds of stationary drilling machines. Among them, the radial arm drill press is often considered as the most important in workshops. The workpiece remains fixed on a table while the spindle moves to where a hole is supposed to be drilled. This is typically for small volume production. Some workshops also have automated drilling machines that can drill several holes at the same time. In all cutting operations, a cutting fluid is normally used to reduce the negative effects of friction heat.

Drills are available at most workshops, although some workshops specialize in more advanced drilling projects.

Compare drilling with CNC drilling, which is used when the drilling has to be very accurate or in patterns. With deep hole drilling, it is possible to do very deep holes.

Drilling projects for quote

  1. Drawings count: 1

    Machining-Drilling

    Drilling of free-issue material is needed for the construction industry. The company behind this requirement has a yearly spend of £80,000 on bespoke machining services. They have advised that the free-issue material will be comprised of varying thicknesses. They seek prices for plow bolts to be drilled as indicated, with some lengths requiring more or less holes. Those that can assist are asked to make contact with the buyer directly to discuss.

  2. Drawings count: 4

    Machining-Drilling

    This manufacturer of sports cars, whose annual spend on subcontract machining services tops a massive £500,000, invites potential suppliers to quote for the attached parts. These are off-the-shelf cap head socket screws that require drilling, in order to accept locking wire within their end application. Initially, the client is looking for 200 off of each part, but has advised that these items will be ordered on a repeat basis, meaning that the successful supplier wins a long-term customer as well as the job in question.

  3. Drawings count: 2

    Machining-Drilling

    This manufacturer is currently looking to hear from suppliers that are able to drill free-issue 'couplings', which are destined for end use within the oil & gas industry. These items will be made from mild steel, with quotes requested for a batch of 200 off at this time. Having experienced quality issues, the client now requires the couplings to be drilled out correctly. They outsource £20,000 worth of machining work every year and therefore, further opportunities could also be made available.

  4. Drawings count: 1

    Machining-Drilling

    Outsourcing a massive £500,000 worth of machining work every year, this company seeks a supplier to drill 3600 off free-issue mild steel bars. They have an immediate order to place for the work in question and will require the parts on an ongoing basis. Therefore, they are keen to build a relationship with a Qimtek member who can facilitate ongoing supply. Those that are interested in this opportunity should make contact with the buyer directly in order to be considered.

  5. Drawings count: 1

    Machining-Drilling

    Drilling and chamfering of free-issue screws is needed, on behalf of a company that spends over £500,000 a year in the subcontract machining market. The client requires quotes on quantities of 100, 500 and 1000 off as part of a contract for which they are currently tendering. If the project is won, it will lead to regular call-offs of the same work. Various sizes of screw will also be required moving forward, meaning that there is plenty of potential for the successful supplier to form a long-term relationship with the buyer in question.

  6. Drawings count: 2

    Machining-Drilling

    Drilling and powder coating of free-issue parts is required, on behalf of a company that outsources machining work to the tune of £100,000 a year. They have an urgent order to place for the work in question as the items were delivered incorrect and subsequently, are keen to speak with interested companies as soon as possible. Those that can assist are asked to quote their best price and delivery in order to be considered, with the parts required by the latest of the 8th December.

  7. Drawings count: 1

    Machining-Drilling

    Drilling, countersinking and chamfering of free-issue screws is needed, on behalf of a company that spends over £500,000 a year in the subcontract machining market. This forms part of a contract that the client has recently won and they would ideally like to improve on a lead time of 15 days. Various sizes of screw will be required moving forward, meaning that there is plenty of potential for the successful supplier to form a long-term relationship with the buyer in question.
