"We always order from Rapidfacture when things have to go quickly and have to fit right away! For us, the ability to know the price immediately is extremely important. This enables us to provide our customers with quick and precise offers."
Prices for custom-made products start at 40 €.
The unit costs are strongly related to the number of pieces. There is an unavoidable, but only one time, cost per order for equipping the respective machine. If the unit price for a single part were to be 70 €, five parts might only cost 150 €. In case of higher quantities, it can also be further automated/optimized (bar loader, multi-spindle turning machine).
Material costs play a subordinate role for single parts with small dimensions below 50 mm. Material costs rise with the diameter about square (according to the increase of the area . The majority of our in-stock materials are at several € per kg. The most expensive materials are V2A, V4A and in particular bronze, which cost more than € 10 per kg.

We are currently working with a network of manufacturing partners that we all know personally. We value good communication, as well as maximum quality. Since we have several manufacturing partners, we are able to place orders efficiently and thus ensure short delivery times. The manufacturing companies are exclusively German specialist companies.
We adhere to the technical delivery conditions of the Association of the German Industrial Parts Industry.
For series from 10 pieces you can get a sample part (e.g. to pre-test or modify). If the order for the series follows, you get the sample part at the serial price, otherwise it is billed as an item.
Turning, together with milling, is one of the most commonly used techniques in the field of metal cutting. Mainly metals, but also plastics are processed. When turning, the workpiece is rotated and the material is removed by means of a stationary tool. This creates a rotationally symmetrical component. Typical applications are tips, nozzles, faucets, but above all machine components from the drive technology such as bearings, shafts, spindles, gear-wheels, cylinders or pistons. Also flanges, as they are needed for attaching electro motors or for joining pipes.
Mechanically functional parts, such as rotating shafts or joints, and especially parts that should fit together, require a high degree of accuracy. The theoretical nominal size cannot be achieved due to deviations in practice. The accuracy is one of the main cost factor in mechanical production. Dimensional accuracy is indicated by tolerances — every measure has a tolerance. For high-precision applications, parts are prefilmed and then respharpened on circular grinding machines, with the precision in the range of single-digit thousandths of a millimeter.
Always make sure, that exact dimensions (e.g. if the part has to fit into a counterpart) are given a sensible tolerance. All untolerated dimensions of a drawing fall under the general tolerance. This can be too coarse for many applications. For example, a bolt with a diameter of 32 mm receives a tolerance of ± 0,3 mm. For high dimensional accuracy, we always produce tolerance center. A measurement with 50 mm and + 0,1 mm tolerance is therefore made to 50,05 mm ± 0,05 mm.
For precise diameter measurements, the fit system is often used to define the tolerance. The definition of fits is made by the fit system, which is always composed of two parameters: An indication of the position of the tolerance (above/below the nominal diameter) and the accuracy indication. For example, the fit „H7“ indicates that it is a fit with the location „H“ (= close to the nominal diameter) with accuracy „7“. H7 is the right fit for many ball bearings — hardly any game, but still pushable by hand. For fits, tolerance class 7 (e.g. fit H7) is standard for CNC turning. Tolerance class 6 can even be achieved. For higher accuracy, the parts have to be sharpened in addition round after turning.
Many inserts have a radius of 0,4 mm. Therefore, inside corners of the rotated contour cannot be made sparp-edged. It is also more advantageous for stability, since sharp transistions weaken components. However, if radii are not allowed (because the part is to be screwed up to the stop and is obstructed by the radius), then a puncture must be applied. Balls, free stitches and small radii can be measured poorly. The tolerances of radii are still difficult to control. Here it is necessary to measure complex with coordinate measuring machines and these are accordingly expensive.
Turning reaches very smooth surfaces. The surface finish is better than milling because the thickness is constant and the cutting process is more stable (lower vibration inclination). More information can be found in the CNC blog Precifast.
A lot of thread sizes can be made by thread cutting. Threads cannot be rotated to a stop — the tool always needs discontinuation space. This is approximately two or three times the thread pitch.
Turning tools have radii on the cutting edge, so that no sharp edges are created on the workpiec, but curves. If a counterpart is to be fitted precisely to the surfaces of the workpiece, these curves are disturbing because the counterpart is here. With a free-stitch, material is removed, so that a space is created. Free stitches are required due to production (discontinuation of the tool) or to ease assembly. Further information can be found in the CNC-blog Precifast.
We send an offer as soon as possible. This takes usually a maximum of three days.
The delivery times are currently in the period of 1-3 weeks. We are working to reduce our delivery times. Many of the materials we offer are now available in-stock up to diameter of 120 mm.
We manufacture only after receipt of payment. We currently offer cash in advance as a means of payment. For larger orders, payment on account is also possible after consultation.
If you would like to cancel an order, please contact us immediately by phone. As far as possible, we stop the order for you. Please understand that an order can no longer be canceled once it is in production.
We ship our products not only to customers within Germany or Europe, but also internationally.
For a quick introduction to the CAD we recommend you to use one of our templates. Maybe your required workpiece is already there, so only minor changes are needed.
Costs are only incurred with one order. The use of our software and your request is of course free of charge.
Our Live Price works with turned parts. They can be uploaded as STEP file, importet and edited in the CAD. You may add Features and tolerances. Other drawind data can also be uploaded, but there will be no price estimation.
A current version of your browser is required to use the online CAD. Because of the high programming effort, the CAD is not adapted for older versions of Internet Explorer (under version 10). Please update your browser, due to certain security vulnerabilities also in your self-interest, if necessary.
We take privacy seriously and keep our IT infrastructure always up-to-date. All connections to the RAPIDFACTURE servers are protected by SSL encryption. Our servers are located in Munich, Germany. We are committed to data protection. Drawings and customer data are only passed on if it is required for the production and processing of the order. Drawings that are created in our online CAD without a login or drawings that are neither explicitly saved nor placed in the shopping cart are not saved.
Accuracy causes costs. Set tolerances only as accurately as required for the function. Preicse parts must first be workd out roughly, measured and then finely processed.
The diameter dimensions of many raw materials are often round dimensions such as 20, 60 or 80 mm. If possible, construct the largest diameter 1 mm smaller than the next round dimension — e.g. 119 instead of 120 mm. This means that the part can be produced with little effort from the raw material 120 mm.
Large ratios of length to diameter cause effort — ideal are ratios under 4:1. Long thin waves turn through during machining, so the processing speed must be reduced.When machining internal contours, the tools turn away, resulting in loss of accuracy. With an intermediate storage (Lunette), even very long workspieces can still be rotated — we do not offer this option. However, drawn/ground shafts can be worked on at the ends with little effort.
Among our standard materials, V2A, V4A and bronze are the most expensive. For individual parts under 50 mm, the material costs are often negligible, but rise strongly with the diameter.
Aluminium is the easiest to work with. The steels V2A and V4A are harder to process due to their high toughness, making the production more expensive. Technical plastics such as POM or PA are well-machinable, but bend easily away, which may require additional devices.
