What is a CNC Machine?

CNC stands for Computer Numerical Control. Numerical Control is the automated control of machining tools by means of a computer. The computer follows a programmed code that contains instructions to process a piece of material.

What is CNC Milling?

CNC Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done in varying directions on one or several axes. This is all controlled by the computer and follows the instructions set by the programme.

What is CNC Turning?

CNC turning is a machining process in which a cutting tool, typically a non-rotary tool bit,
describes a helix toolpath by moving more or less linearly while the workpiece rotates.
turning, the workpiece (metal or plastic) is rotated at high speeds and a cutting tool is traversed along 1, 2, or 3 axes of motion to produce precise diameters and depths.

What materials can be machined?

At KMF Precision Engineering we can machine a wide variety of materials and regularly machine:
Carbon/alloy steels
Stainless steels
Specialist steels
Aluminium castings

What types of CNC machines does KMF use?

Here at KMF Precision Engineering, we have a wide variety of CNC machining and turning machines available to produce your parts. We have 2-axis, 3-axis and 5-axis milling machines and 3 axis and 4 axis turning. We have 2 sliding head machining centres that allow both turning and multi-axis milling. Horizontal machining with our Mazak HCN 5000-111 with synchronised running of 12 pallets allowing a suite of parts to be run in one visit.

What is the difference between 3-Axis and 5-Axis machining?

The main difference between 3-axis and 5-axis milling machines is that the workpiece can be worked on from three axes with the former and five axes with the latter. Both are highly versatile, automated, and replicable production processes that will enable you to quickly and cost-effectively create accurate components.

What size can KMF machine up to?

KMF Precision Engineering can machine a part up to 3000 x 800 x 1000mm in size using our Mazak VTC 800/30SR which has a simultaneous trunnion + B axis head with an 18,000 rpm HSK- 40 spindle.

Does KMF offer subcontract manufacturing?

Here at KMF Precision Engineering, we will happily help with your subcontract manufacturing requirements. We have the machines and staff capable of producing high precision engineered parts in low to high volumes, depending on your needs.

What finishes does KMF offer?

From a strong base of approved and trusted suppliers, we can provide a range of metal finishing services, including, zinc electroplating, anodising (both decorative and hard), phosphoric bond,
hexavalent chromium-free, nickel plating and CARC. We also offer in-house engraving and bead blasting and vibrating tumbler facilities. We will be happy to help with any other finishes required.

What accreditations do KMF hold?

KMF Precision Engineering currently holds AS9100 and AS9001

Machined parts you can trust

KMF's machined components need to perform with pinpoint accuracy in the most demanding environments and therefore we recognise the importance of quality and precision in our products. To ensure all processes are performed to the highest quality standards, KMF Group carry ISO 9001 approval as the baseline for our quality system.
