Guhring UK Unequal helix geometry achieves speedier milling

| Editor: Barbara Schulz

UK – A Devonshire linear motion specialist was looking for efficiency gains in its milling department. Trying to slash cycle times from 20 to five minutes, engineers found that a particular range of undersized cutters were the right size for the job.

Recognised as the originators of the V-slide and bearing guide system used worldwide for the control of linear, rotary and continuous motion, Hepcomotion is said to be the largest manufacturer of linear motion products in the UK. Formed in 1969, three quarters of the company's output is now being exported.

Special end geometry enables high-speed machining

Taking delivery of its first Guhring cutting tools five years ago, the use of Guhring drills, milling and threading products has resulted in the Tiverton company now retaining a consignment stock of said products. Commenting on the partnership, Martin Shapland, CNC process engineer at Hepcomotion, says: "We use a lot of Guhring's milling, drilling and tapping products. This includes 5XD solid carbide drills and Ratio RF milling cutters with an unequal helix.” The unequal helix of the RF tools is claimed to improve chip flow and surface finish and to reduce vibration said to extend tool life and consistency.

Guhring's Regional Sales Engineer Ian Goffey says: “The new Diver line is a versatile cutter that will machine mild steel, stainless steel, cast iron, aluminium and a wide variety of super alloys. It removes swarf from the work area and tool whilst the end geometry enables the Diver to plunge in at 90 degrees or even ramp into a workpiece at 45 degrees. This combination gets the chips away from the job, which makes it suitable for high-speed machining."
