MXR Micro Back Turning Bar Overview

The MXR Series is a precision-ground solid carbide micro back turning bar designed for machining rear faces, internal undercuts and recessed features behind shoulders in small-diameter bores. The tool enters through the bore, passes the internal shoulder and cuts during a controlled reverse-feed movement.

Standard models cover cutting diameters from Ø2.8 to Ø5.9 mm, cutting widths of 1.3 and 1.5 mm, and clearance lengths from 10 to 22 mm. The one-piece carbide construction provides the rigidity and dimensional stability required for restricted-access internal machining.

Fitur Utama Produk

• Reverse-Feed Back TurningDesigned to pass an internal shoulder and machine the rear face or recessed feature during reverse tool movement.
• 30° Cutting GeometryThe defined cutting geometry provides clearance for controlled back turning and internal undercut machining.
• Small-Bore AccessibilityCutting diameters from Ø2.8 mm provide access to rear-facing features in miniature and precision-turned components.
• Rigid Solid Carbide BodyFine-grain solid carbide construction helps control tool deflection and supports repeatable rear-face dimensions.

Panduan Pemilihan

1. Check Entry ClearanceConfirm that the tool tip and neck can pass through the bore before moving behind the shoulder.
2. Confirm Rear ClearanceCheck that sufficient space is available behind the shoulder for radial positioning and reverse-feed cutting.
3. Select Width and DepthThe selected cutting width B and depth Q must cover the required rear-face or undercut dimensions.
4. Minimize Tool OverhangUse the shortest practical L1 and the largest compatible shank diameter to improve rigidity.

Kondisi Awal yang Disarankan

  • Atur ujung potong secara tepat pada garis tengah spindel.
  • Confirm the spindle direction and programmed reverse-feed direction.
  • Simulate the complete entry, positioning, cutting and retraction path.
  • Do not move the tool radially into cutting position before it has cleared the shoulder.
  • Begin with a conservative cutting depth and feed, especially on the 22 mm clearance-length models.
  • Use suitable coolant or compressed air to prevent chip accumulation behind the shoulder.
  • Reduce the cutting load if vibration, taper or rear-face dimensional variation occurs.

Pertanyaan Umum & Unduhan

Pertanyaan Umum tentang Produk

What are MXR micro back turning bars used for?
MXR solid carbide micro back turning bars are designed for machining rear-facing surfaces, internal undercuts and recessed features behind shoulders in small-diameter bores. The tool passes through the bore and machines the feature using a controlled reverse-feed movement.
What cutting diameters are available?
Standard MXR models cover cutting diameters from Ø2.8 to Ø5.9 mm. Available shank diameters include Ø4, Ø5 and Ø6 mm, with clearance lengths of 10, 15 and 22 mm depending on the model.
What cutting widths and depths are available?
Standard cutting widths B are 1.3 and 1.5 mm. Depending on the model, the catalog cutting depth Q ranges from 0.6 to 1.8 mm. Both dimensions should be compared with the required rear-face or undercut geometry.
What does the 30° geometry represent?
The 30° value identifies the back-turning cutting geometry shown in the technical drawing. It provides clearance for machining behind an internal shoulder. The component geometry and complete tool path must still be checked before machining.

Pertanyaan Umum (FAQ) tentang Seleksi & Pendaftaran

How do I select the correct MXR back turning bar?
Select the model according to cutting diameter d1, nose radius R, cutting width B, cutting depth Q, clearance length L1 and shank diameter D. Verify that the tool can enter the bore, pass the shoulder and move into the cutting position without collision.
How is an MXR tool different from a conventional boring bar?
A conventional boring bar normally machines the bore diameter and forward-facing internal surfaces. The MXR cutting edge is oriented for reverse-feed machining of rear faces and recessed features positioned behind an internal shoulder.
What materials can be machined with MXR back turning bars?
Typical applications include carbon steel, alloy steel, stainless steel and copper alloys. Selected tools can also machine pre-hardened steel, cast iron and titanium alloys. Application-specific coated versions are available for titanium and other difficult-to-machine materials.
How can I prevent a collision during back turning?
Simulate the complete entry, radial positioning, reverse cutting and retraction sequence before production. Do not move the tool radially into the cutting position until the cutting edge has completely passed the internal shoulder.
How can I improve machining stability?
Use the shortest practical clearance length and tool overhang, select the largest shank diameter permitted by the bore, and use a high-precision holder. Reduce the cutting depth and feed if vibration or rear-face dimensional variation occurs.

Pertanyaan Umum (FAQ) tentang Pemesanan & OEM

Can you manufacture custom MXR back turning bars?
Yes. Cutting diameter, nose radius, cutting width, cutting depth, back-turning profile, clearance length, shank diameter, coating and overall length can be customized according to the component drawing or application requirements.
Can I order mixed models or trial quantities?
Yes. Mixed-model requirements and small trial orders can be reviewed according to the selected sizes and available stock. The standard minimum order quantity is normally 10 pieces, subject to final model confirmation.
Is OEM marking and private-label packaging available?
Yes. OEM services can include laser marking, custom model identification, private labels and distributor packaging. Please provide the logo file, marking position and packaging requirements when requesting a quotation.
Informasi apa saja yang diperlukan untuk mendapatkan penawaran harga?
Please provide the standard model or component drawing, bore entrance diameter, shoulder diameter, rear-face width, machining depth, workpiece material, tolerance, quantity and any coating, marking or packaging requirements.
What is the lead time for MXR back turning bars?
In-stock standard models can normally be dispatched within 1–3 working days after order confirmation. Customized tools require separate lead-time confirmation according to the geometry, coating, quantity and inspection requirements.
